Results of the competition aside, we would like to thank each and every team for making our experience over these past few weeks one that we'll never forget. During touring, we received multiple comments that the quality of the entries were consistently good from one end of the mall to the other. We couldn't agree more. We've had the opportunity to meet a lot of great people from other teams and hopefully we'll cross paths again in the future. Good luck to everyone getting packed up and making the trip home after tours conclude. If you're anything like us, the prospect of taking the house back apart and shipping it home is a lot less appealing than setting it up on the mall. It's a lot more fun to put it together anticipating the event than it is to take it apart in the aftermath of weeks of hard work. Maybe the National Parks Service would be interested in a permanent pavilion... :)

Contest Results - Communications
Posted on October 13, 2009
Results for the communications jury are in. Here is a recap, including the description of the contest from the Solar Decathlon website. Communications - 64.5 Points out of 75 (5th place) The Solar Decathlon challenges teams to communicate the technical aspects of their houses, as well as their experiences, to a wide audience through Web sites and the public exhibit of their houses on the National Mall. The Communications contest awards points based on their success in delivering clear and consistent messages and images that represent the vision, process, and results of their project. A jury of Web site development and public relations experts evaluates the team Web sites, communications plans, and National Mall exhibits for effectiveness. In addition, the jurors assess each team's: 1. Planning and audience analysis 2. Web content quality, appropriateness, and originality 3. Information presentation, including graphics, photos, Web site organization, and on-site displays 4. Branding to help make the project identifiable or memorable in some way 5. Delivery of team messages to target audiences and people of all abilities 6. Innovation of methods to engage audiences, including the Web site visitors and people waiting to tour the home.
The main component of this jury was a simulated tour in which team members guided the jurors through the house in order for them to see how the house is being presented to the general public. Following a brief introduction at the front steps, Courtney Keys began with an overview of the inspiration for the house as well as a description of the landscape and passive features. Lucas Dixon explained the mechanical closet prior to the jury entering the house. Once inside, Neal Clements went over the design inspiration for the interior of the house and the manner in which one conceptually interacts with the space. Lucas went over the home automation system prior to passing the tour off to Deanna Hinkle for a demonstration of the house's operable features. Following a few brief questions, Jared Lairmore highlighted a few aspects of the tour such as the signage displays and the stamp the team provides with a link to the team website.
As always, contests are ongoing and the overall rankings change daily. You can access current standings at http://www.solardecathlon.org/scoring. Also, for more information on specific jury members, please visit http://www.solardecathlon.org/juries.cfm.

Contest Results - Architecture and Market Viability
Posted on October 13, 2009
Results for the first two major juries in the "subjective contest" categories are in. Here is a recap of each, including the description of each contest from the Solar Decathlon website. Architecture - 82 Points (8th Place) Teams are required to design and build attractive, high-performance houses that integrate solar and energy-efficiency technologies seamlessly. A jury of professional architects evaluates team construction documents and the final constructed house. It evaluates three main factors: architectural elements, holistic design, and inspiration.
Deanna Hinkle, Steve Winter, Dave Nedrow, Jared Lairmore, Courtney Keys, and Neal Clements were the team members involved in the architectural jury presentation this past Saturday. The main points of emphasis the team focused on were the house as a reinterpretation of the American living condition, the manner in which the house references Ohio's heritage, thoughtful integration of architecture with passive and active systems, and adaptability of space, specifically the way in which the user interacts physically with the house. The most enjoyable aspect of this tour was demonstrating the operable features for the jury, as this interior manipulation is not possible during larger public tours. All three of the jurors were engaging and asked great questions. Unlike many "architectural juries" where the format is a bit rigid, this presentation ended up striking a nice balance between a relaxed presentation and casual conversation. In the end, we're very pleased with the final result and thoroughly enjoyed the experience.
Market Viability - 91 Points (5th place: tied with Minnesota and Germany)
Teams build their houses for a target market of their choosing. They are then asked to demonstrate the potential of their houses to keep costs affordable within that market. A jury of professionals from the homebuilding industry evaluates how well suited the house is for everyday living, determines whether the construction documents would enable a contractor to construct the house as intended, and assesses whether the house offers potential homebuyers within the target market a good value.
Jared Lairmore and Deanna Hinkle began by explaining the house as a reinterpretation of the way in which the typical American house allocates space and the manner in which one interacts with their physical environment. Key points of emphasis were the way in which the occupant can easily adapt the space to a variety of situations and overall livability. Steve Winter and Neal Clements followed up with a taboo topic for many designers (money) and explained how the house uses readily available, off-the-shelf building components and prefabrication as a means of keeping costs down. They also noted that the house uses typical construction techniques optimized for efficiency in order to engage the existing workforce of residential contractors. Kurtis Meyer and Lucas Dixon finished by explaining how the house can be utilized as an infill project in several Columbus, Ohio neighborhoods as well as in less dense development. They also noted how the house addresses the two fastest growing market segments in central Ohio, those being young professionals and empty-nesters.
We'd like to thank the jurors for each contest for their time and interest. It is evident that the contest organizers did their homework in selecting qualified, engaging sets of jurors and we enjoyed the interaction during our presentations. Other contests are ongoing and the overall rankings change daily, so please check the DOE Solar Decathlon website for updates. You can access current standings at http://www.solardecathlon.org/scoring. Also, for more information on specific jury members, please visit http://www.solardecathlon.org/juries.cfm.

Interior Shots
Posted on October 12, 2009The competition has been in full swing for several days now and things are going great. We're having a great time interacting with people during touring and can't thank everyone enough for coming out to see the house. What a great experience. Things have settled down a bit and we've been able to take some photos of the interior of the house. Enjoy!

Finally...Some Time to Post
Posted on October 8, 2009We've been working about 16 hours per day since October 1st to get the house finished for touring. Last night we received our final sign-offs from all of the various Solar Decathlon code officials and today we spent the morning cleaning the house, picking up the site, and touching up the finishes. After the opening ceremony (where our own Lucas Dixon did a fantastic job with his speech, by the way) the house opened for VIP touring. This afternoon, 998 people toured the house and the team had a great time interacting with everyone. After all of our hard work, it was very satisfying to show the house and we really appreciate all of the positive comments. Here are a few pictures from today.

Let's Go To The Mall
Posted on October 1, 2009As this post is being typed, the house is taking shape on the mall. Steve and Deanna were on site early this morning to set up the transit level to locate the first piece. The crew from Greenlawn dropped off the first module and it is leveled and in place. Dave is riding with the second module and it will be on site shortly. If all goes well, all three modules will be in place within the next few hours ready to seal back up in to a single house. After all of our work to get here, today is a satisfying payoff. There is certainly a lot left to do, but this moment feels pretty good. Pictures will be posted once we are able to download some from our cameras. Check back!

Someone Stole the House!
Posted on September 28, 2009
The first of many thank you's goes out to the people at Greenlawn Homes, who have generously donated their services to help us move everything to
I have to admit, it looks strange on the build site with no house. In a few days the trailer and fence will be gone and all that will remain after 10 months of hard work is the gravel we laid for our vehicles to drive on. While it is exciting to have our house on the road, I'm sure we'll look back in the not too distant future and miss the fun we had together at the build site. Thanks again to National Rent-a-Fence for supplying the construction fence and Roger Beck for loaning his solar-powered storage trailer. Both of you have been an integral part of our success and we really appreciate your help.

The Entertainment is Here
Posted on September 28, 2009The last large piece of casework to finish is the entertainment area. Two slots have been installed to receive the two collapsable dining tables. The tall narrow panel to the right will incorporate a pull-out cabinet that will store the dining chairs and other various items. The large panel to the left will house all of the electronics for the house and will pull out of the wall to reveal additional storage behind. (We just need to cut the hole for the TV screen.) The lower cavity will serve as storage for the couch when it is not in use. This area will be completed over the weekend in time to ship the house to DC. We're down to the wire...wish us luck!

The Kitchen
Posted on September 28, 2009
The kitchen is an exercise in coordination, sequencing, perseverance and swearing. When you're trying to make a space that is only 6'-8" long accommodate all of the items necessary to prepare a meal, space for installation gets a little tight. But this house is about efficiently using every bit of volume and trust me, we did. After fabricating the maple butcher block countertop and cutting the holes for the various appliances we took it to the site and set it in place. Fit like a glove. A couple of hours and we'd have everything installed, or so we thought...
First up was the drawer-style dishwasher. If the instructions tell you an appliance requires a rough opening that is 23-1/2" wide, and you build a cabinet 23-1/2" wide, you would expect it to fit right? Turns out the fit was a little tight, but with a little bit of gentle persuasion we got it in. Lesson learned: Give the rough opening an extra 1/8" and you won't be sorry.
The downdraft ventilation went in next and the main challenge here was routing the duct from the bottom of the blower box through the floor with only 6" of depth to make the turn. After hours of frustration for Neal and Deanna, SuperLucas stepped in and got the job done. Lesson learned: Delegate all ductwork tasks to Lucas immediately. There's no shame in deferring to the master.
The combination microwave/convection oven (aka micro-hood) beneath the cooktop went in without too much hassle, although we had to make a custom bracket to hold it up. Generally this appliance is installed above a stove and held up with two screws through the cabinet above. However, in this instance, the countertop was already in place because you can't install the downdraft ventilation without the counter. So we needed to lift up the counter to put the screws through the cabinet. But you can't install the micro-hood without first installing the downdraft ventilation behind it, which required the counter to remain in place. You see the problem. Lesson learned: Consider your sequencing when finalizing design or you'll have to fabricate a custom solution.
Finally, the Kohler sink and faucet went in and all items were installed. We only had to make a slight modification to the location of one of our holes, otherwise everything went smoothly. Lesson learned: Measure your sink flange to make sure you're not going to hit it when you drill your faucet holes.
We finished deep breaths and high fives all around. As my father always says, there's a bite to every project and it held true in the kitchen. We faced a little challenge with each step and everything took twice as long as we thought it would, but there wasn't anything we weren't able to overcome. All that is left to do is install the doors and drawer fronts and it will be ready to prepare a memorable meal in DC. We can't wait!

Bathroom
Posted on September 28, 2009
The frosted glass bathroom doors have been installed along with the vanity, the sink, the lights and the toilet. Kohler has been kind enough to donate all of the fixtures and they installed with no problems. The highlight is the dual flush toilet, which will save thousands of gallons of water per year over a standard toilet. Not only that, but it looks great too! The last thing we need to put in is the faucet, which we'll do in the next few days before we head out for DC.
Coordination Tip: Be sure to measure the location of your shut-off valves before you build your vanity, otherwise one might fall right on the edge of the cabinet. (Note: This was not the plumber's fault...this one was on me.) Luckily, Deanna quickly figured out a way to install a false panel on the side to cover the mistake.

To Bed I Said
Posted on September 28, 2009The pull-out bed unit has been installed on its track and is operating smoothly. The bed rides on linear bearings recessed in the ceiling cavity and is supported by non-marring casters on the floor. In the stored position it aligns with the office/closet interface wall for a seamless transition. When bedtime rolls around, it is easily rolled out of the wall and flips down to reveal a queen size mattress. By combining standard Murphy Bed hardware in a custom case with an off-the-shelf set of linear bearings in the ceiling, the seemingly complex operation of moving a giant bed and storing it in a wall becomes deceptively simple.

The Doors
Posted on September 28, 2009The operable interface doors have been installed outside the office/closet area and near the kitchen. We had a minor ordering mix-up which we discovered the first time we tried to lift a door. We ordered hollow core, but they came solid. Initially this was a source of concern, but now that they are installed they have a really nice, solid feel because of the added weight. Thanks to Chris and Dwight for their assistance in getting these in place. You guys really helped us out in an situation where time was in short supply.
They're heavy!

Tile
Posted on September 28, 2009The bathroom has received tile on the walls and floor and we're ready to install the interior polycarbonate and trim. The walls are a glossy 3x6 tile installed in a running bond pattern, and the floor is a 3x12 with a more matte finish. Next step is to install the fixtures. Stay tuned!

OSU sends the Solar Decathlon Team off with cheers! (9/25/09 OSU)
Posted on September 26, 2009Today several hundred students rallied behind Solar House 1 to send her off in style. The Central Ohio Brass Band and Brutus Buckeye, seen just to the left of President Gee, contributed a festive spirit. After remarks by Interim Dean of Engineering Greg Washington, Knowlton School of Architecture Director Ann Pendleton-Jullian, our dear President Gordon Gee, and three students, we all joined in the first verse of Carmen Ohio. It was really wonderful to see all the students who came out to support us!

Special Delivery
Posted on September 14, 2009We'd like to thank Dave Hinkle, Deanna's father, for taking the time to pick up our sofa frame and the electronics for our entertainment center. We attempted to purchase the sofa frame locally but it was out of stock and wouldn't have been delivered in time to finish the house. Dave drove to Pittsburgh from his home in Youngstown to pick one up at another store prior to his visit to Columbus for the USC game. That equates to an extra 9-10 hours we were able to spend working on the house instead of driving. As time to finish runs short, these additional hours are significant. We should probably also thank Dave and his wife Debbie for doing such a great job raising Deanna and let them know how proud they should be of their daughter and her contributions to this project. But we won't do that because Deanna would blush and get all bashful, and we'd be accused of being sappy. So we'll stop at thanks for your help. We really appreciate it.

Recycling Your Wood Scraps
Posted on September 10, 2009You couldn't throw this away if you tried. (No...really. We throw it all the time, and he always brings it back.) In the absence of a tennis ball or chew toy, a piece of 2x4 will do quite nicely.

An Exterior Update
Posted on September 10, 2009We haven't posted any shots of the "completed" exterior yet, so here they are! We still need to finish fabricating and installing the horizontal louvers in front of the translucent panels on the south side and install the pop-off panel over the inverter closet, but for the most part we're finished with exterior work on the house. The decks and landscaping won't be installed until we get to the mall because we don't have the space on site, but consider that an invitation to come see us in Washington D.C. We hope to see you there!

A Dab of Sunblock
Posted on September 10, 2009In order to control solar access to the south side of the house, we're fabricating fixed horizontal louvers from marine grade plywood. The intent is to space them such that summer sun is blocked while winter sun is allowed to hit the polycarbonate which will in turn heat the water contained in a series of tubes between the layers of polycarbonate panels. It is basically a trombe wall that relies on the thermal storage capacity of water rather than a solid mass so that light is still permitted in the space. And now for a Solar Decathlon fabrication discovery. What is the best surface for laminating layers of plywood? 10' sawhorses or course! These super-sized sawhorses were left over from finishing the ceiling panels where we used them as a large spraying/drying rack. Turns out they make a great surface for clamping long boards while keeping them straight. We plan to leave them on the large work porch outside the Knowlton Hall woodshop where we're pretty confident that architecture students will find countless other uses for them in the coming years.

Casework
Posted on September 10, 2009The house is now entering the finishing stages and we're dedicating a significant portion of our time to building the interior casework in the Knowlton Hall woodshop, located just down the street from the site. We're done building the closet & office, the bedroom shelving & flip-down bed unit, the bathroom vanity, the kitchen pullout shelving, and the laundry unit. In the next week, we anticipate working on the entertainment center and the lower kitchen cabinets as we receive our furniture and appliances. More photos will follow as we install the pieces. Check back!

Exterior Soffits
Posted on September 10, 2009Similar to the interior ceiling, the exterior soffit is a series of 12" wide fibercement panels in order to maintain continuity between interior and exterior. As we wire the exterior lights, these panels are being installed and painted. Once we're done with the exterior, we'll move inside and continue in a similar manner. The interior ceiling has been fully insulated with Owens Corning batt insulation and has received 2x2 furring to accept the ceiling boards. We'll post progress pictures once we get started (hopefully next week).

Plumbing & Electrical
Posted on September 10, 2009We're rolling along with the rough-ins for each system. In fact, we're virtually done with rough plumbing with the exception of the tanks below the house. We're hard at work on final wiring, hooking up the inverters, and the home automation system. We also hope to wrap up the lights shortly so we can start installing the ceiling boards. We'll post an exhaustive entry on each system once we're done, but in the mean time we'd like to thank the guys from Muetzel plumbing and Michael from Watt-1. You all have really helped out a lot and we couldn't have gotten this far without your efforts. We can't say enough how much we appreciate everything you've done and how much we've enjoyed working with all of you.

Louver Installation
Posted on September 10, 2009Here are a few shots of the louver installation. One of the challenges related to building this house has been sourcing off-the-shelf hardware for the operable features of the house. The louver pivot hardware was no exception. Fortunately, the hardware we selected works flawlessly. After recessing a bracket in the floor & ceiling and a pivot on the top & bottom of the louver framework, the pivot is simply set in to the lower bracket and tilted in to place. While in the open position, a screw is turned in the upper bracket which extends the top pivot pin to engage the top of the louver. Once the hardware was in place, installing each lover took less than 2 minutes apiece. Each panel has a kick-stop so that it can fixed in any position. Now that the louvers are installed, we've adjusted them to block the evening sun and it has made our working environment much cooler. Isn't it great when a plan comes together?
Almost there...

My Own Fastener Flea Market: A Little Bit of Everything
Posted on September 10, 2009After working on this project since December and receiving constant ridicule for my messy tool pouch, I finally decided to clean it out. Steve's argument is that it is hard to find anything when your pouch is a mish-mash of various fasteners. My argument is that I've always got what you need (as long as you only need a couple). I counted 17 different types of fasteners while organizing. Can you find them all? --Neal

Flooring
Posted on September 10, 2009The team has recently completed installation of the hardwood floor. The product is a 3" wide, random length tongue & groove board installed with a standard flooring stapler. There are two unique challenges to using a continuous hardwood floor in this house. First, the modules need to come apart and reassemble on the mall so nailing down all of the boards is not an option. To get around this issue, we created joint covers that are 4 boards wide glued together in to a solid unit. By ripping off the bottom grooves on the outermost edges we are able to set these boards in to place over the joints and create a virtually invisible joint line. By cutting 1/2" deep saw kerfs every 2" on the underside of the joint covers they become much more flexible. This will insure that the boards will lay flat and accommodate slight variations in alignment. A little carpet tape is all we should need to keep them in place. Second, the floor contains radiant tubes which would leak if they were punctured by fasteners. To solve this problem we selected a board width (3") which breaks down evenly within the spacing of the tubes (12"). By determining the maximum reach of the 2" flooring staples, we were able to start the boards in a position where they would not hit the tubes. We don't have any pictures of the completed installation because we had to cover the floor with paper and Masonite as we were working to prevent damage, but we'll be sure to put up photos of the finished interior when everything is complete. Solar Decathlon Tip: If you're using a flooring stapler, make sure that the little screws that hold the protective rubber sole in place are fully tightened. If not, they will leave a large gash in the floor everywhere you drive a staple (very hard to see at daybreak when the sun isn't fully up) and you will have to remove several rows of boards. Ask us how we know... The wood flooring over our radiant subfloor.

Drywall: Pretty Dry Stuff
Posted on September 10, 2009While it isn't the most exciting thing in the world, the drywall is all done and the joint compound has been applied and sanded smooth. Next step - paint!
- Login to post comments
We're Finished
Posted on September 10, 2009Applying paint and stain inside the house can be a time consuming and difficult process because there are always several people working on different parts of the house, kicking up dust, moving materials, etc. In order to alleviate this problem, we're trying to pre-finish as many elements off-site as possible. In the case of the ceiling boards, which consist of 1/2" plywood ripped to 12" wide, laying the boards flat on a set of sawhorses does the trick. The plywood is prefinished, so we only have to spray one side with a coat of primer and a couple coats of white latex paint. Some things, however, require building custom fixtures to make the process go faster. In the case of the slats for the louvers, we built a hanging rack so we could finish all sides of each slat at once. (And so we don't get hit with any safety violations, I should mention that right after this picture was taken we thought better of standing on a bucket and got a stepladder.) Some things you just have to finish on site. We've been taking turns priming and painting late in the day after a bulk of the site activity has ended. While the house isn't large by today's suburban standards, there are still a lot of windows to cut around and a lot of nooks and crannies. Thanks to everyone who has helped out with this tedious but important effort. Spraying the boards. The custom built louver finishing rack. Tedious painting around the windows.

D Minus 22 and Counting
Posted on September 8, 2009Just about everyone is familiar with "D-Day" the start of the Normandy Invasion that led to the end of World War II in Europe. However, it is lesser known that D-Day is not a term specific to June 6, 1944; D-Day (short for 'day of days') is the actual start of a campaign and the days leading up to it are counted down D - 3, D - 2, D -1 and the following are counted up D+1, D+2, D+3.... Our own D-Day is September 30, 2009, when our house will go forth from Columbus to Washington D.C.. We like sharing tidbits, just like this one.
In the spirit of spreading information, great changes are going to be coming to the OSU Solar Decathlon website in the days leading up to competition. There will be more content in each of the sections, with more useful information about the competition, resources to apply alternative energy solutions to your own homes and better guides to further your knowledge and enable you to work for a better energy future. One of the changes, to make finding new content easier, will be updates on the homepage about the latest and greatest stuff to see in the coming weeks, along with the current score and rank of OSU as the competition progresses.

Labor Day: Green Living Fayre: 23 Days Remaining
Posted on September 8, 2009
Labor Day saw the OSU Solar Decathlon Team in Zanesville, Ohio for the Green Living Fayre. James, Kurtis, and Neil went down to promote Solar Decathlon and raise awareness of the impending competition. Despite some inclement weather, the event was relatively well attended. Those who stopped by the booth got to learn from our wall insulation mock-ups, the evacuated tube array model, and were directed to stay tuned as the competition gets under way. It was a fun event, where we met some future OSU students, new acquaintances in the sustainability advocacy community, and people with unique perspectives on energy and the environment.

24 Days left, Getting the Control We Needed
Posted on September 6, 2009Work continued today on Solar House 1. Installation and calibration of the sensors and other controls equipment was executed. Only fine-tuning remains on the house's control system. Soon, we will be harmonizing our house's climate controls with the weather and catering our energy consumption to our sun's radiation. While little over three weeks remain before OSU Solar Decathlon is DC-bound, we are confident that we will be ready.

Posted on September 5, 2009As of day there are only 25 days left before Solar House 1 is Decathlon bound! To keep you informed of our final preparations, send-off events, and the Solar Decathlon itself, the blog will have a new entry everyday from now to the close of the competition.
The House Today
To start off this countdown right, not to mention the football season, our Ohio State Buckeyes triumphed over the strong opposition of the U.S. Naval Academy's Midshipmen. Just a few hundred feet away from this heated competition was our own contender, Solar House 1, awaiting the Solar Decathlon.
As you can see, the house now has solar panels! Additionally, our house is insulated, floored, and generally shaping up to be a lean, mean, green, holistically livable, wholly sustainable, energy-generating machine. That said, we should take a look at the heart of our energy solution, the Sanyo bifacial photovoltaic panels.
The solar cells are built on a transparent base. Which is not only aesthetically cool, it is a great advance in the efficiency of crystalline solar cells. Sunlight that hits the house through our around the arrays will be reflected back up by the white roof membrane and hit the back of the solar cells, which work just as well as the front. This means that our house, along with others that adopt this technology, will be able to generate more electricity and for a longer period in the day than has been possible before.
We're really excited about this.
Check back in tomorrow, to get a preview of upcoming events!

Good Day Columbus!
Posted on September 3, 2009FOX 28 - WTTE visited OSU Solar Decathlon at Solar House I yesterday. Five members of the Team were interviewed in segments live on Good Day Columbus. Lucas, James, Bethany, Erin, and Jared discussed an overview of the house, the pillow tank water system, events at the Decathlon, home automations controls, and design and barn siding. You can see the segments here. Thanks to everybody involved for making this happen, especially Johnny and Adam at Fox 28.

The Birthday Boy
Posted on August 12, 2009If we're having a stressful moment, encouraging tail wags and a break to play fetch are very therapeutic. Happy birthday to the best jobsite dog of all time. We love you Motown!

A Little Help From Big Brother
Posted on August 11, 2009Another piece of the exterior envelope has been installed. The translucent polycarbonate panels on the south side of the house are complete with the exception of the hopper window in the bathroom. Special thanks go out to APSCO for donating and fabricating the aluminum extrusions and trim pieces for these openings. It was a bit of a family affair, as Steve Winter's father worked for APSCO prior to his retirement, and his older brother Brad is a current employee. Brad made a special trip from the Cleveland area down to Columbus after work one night last week to help us set the PolyGal polycarbonate panels and make sure everything was sealed up just right. It was a bit of a late night, but we got it all done. Thanks Brad. You really came through for us. And now for a side story just because I got a kick out of it when Steve told me. Brad and Steve's dad came to Columbus in June to visit for graduation, and the three of them went to the site that Saturday night just before dusk to take a look at the house. They got to talking about whether or not we had verified if the house would fit under bridges. A bit nervous at the prospect of a newsworthy disaster, Steve got out the tape measure. Steve's dad stood back, eyeballed the facade, and said, "Looks like about 13'-2"." Steve hooked the tape measure on to the parapet and dropped it to the ground. You guessed it....13'-2" right on the nose. Dad's still got it. --Neal

Solar Houses Are For Louvers
Posted on August 11, 2009Since the house is intended for a young couple, the east and west ends facades have operable louvers to insure that things don't get too hot inside (from unwanted solar heat gains, of course...) Oak strips have been sanded, stained and attached to white powder coated aluminum frames. Each end of the house has four units which pivot to allow a wide range of configurations based on the sun and/or the activities going on in the house. The east end is next - stay tuned!

All Decked Out
Posted on August 5, 2009Construction of the decks has started and we're really flying along. The sub-assemblies that will be ganged together to form the large outdoor living space are framed and we're getting them set up outside the house. These modules are constructed of standard 2x8 pressure treated lumber and will sit on double 2x12 framing. The pieces are small enough that they can be taken apart for transport and easily moved and re-assembled by a team of a few people without any heavy machinery. We don't have enough room on site to install the deck in its final configuration on the west end, but we plan to mock up the east end as a test. We're still sourcing finish decking and railings, but they should be finalized shortly. We'd also like to express our gratitude to Jim Bieser at Contract Lumber for helping us out with the deck lumber order. We worked with Jim on the initial framing lumber order for the house, and we had such a great experience we gave him another call. Just like the first time, we got exactly what we needed and it arrived really fast. Thanks Jim! Deck framing progress.

What's All This Stuff In The Closet?
Posted on August 5, 2009A large portion of our seemingly enormous mechanical closet has now been filled in with the solar-thermal system. We would like to extend our sincere thanks to Dave Hammontree and his team for their generous donation of materials and help installing everything. We have one rack of evacuated tubes mounted on the south side of the west module, and another rack mounted on the roof. These tubes cycle water through a loop in to the large tank in the mechanical closet, which in turn helps heat the water for our radiant floor system and domestic water. The bulk of the piping runs within the west module so we will only have a few connections to make under the house once we get to Washington DC. We can't wait to wrap up the final finishing touches, install the evacuated tubes and test it out!

Siding Update
Posted on July 30, 2009The rest of the siding is finished with the exception of small areas on the east and west ends we're waiting to install until we're done with the louvers. As expected, the east, west, and south sides took considerably less time because the pieces were much smaller and easier to work with. We're within a few weeks of completely wrapping up the exterior and moving to the interior full-time. We'll post photos of the finished product, so be sure to check back!

North Facade: Done!
Posted on July 10, 2009"Diligence is a good thing, but taking things easy is much more restful." --Mark Twain
After several long days of diligence, the north side of
the house is completely clad with salvaged barn siding. We can really
get a sense of the exterior of the house now and we couldn't be more
pleased with the way everything is looking. We'll begin the other
facades next week which, now that we've conquered the north side, will
seem tiny by comparison.
Other updates: Mechanical and electrical rough-in work
continues on the inside. We're placing the order for the deck framing
lumber and working on sourcing the finished decking. Our goal is to
begin constructing decks within the next couple of weeks. Team members
will be meeting with a metal fabricator this afternoon to discuss
operable parts for the rotating louver panels at the east and west
ends. The plywood order for the interior casework is being finalized,
with the idea that some team members will begin fabrication of the
interior elements while others work on the decks. The polycarbonate
panels for the south side have been ordered and will be here in a week
or so. We'll post more photos as we make more progress. Check back!

Point/Counterpoint: Salvaged Barn Siding & Hardie Board
Posted on July 4, 2009The parapets have been capped with sheet metal copings and we've started installing the salvaged barn siding on the north side of the house. While it has been exciting to see this part of the exterior take shape, we've realized that this is going to be a long, tedious process. As one might expect with salvaged material, it has a fair amount of variability in terms of thickness, warping, cupping, and bowing. We've developed a few jigs to help position the wood and locate the screw holes which has sped up the process some, but a fair amount of care is still required to make sure that each board ends up plumb and straight with an even gap along its length. All that said, we couldn't be more pleased with the final results thus far. All of the work that has gone in to preparing and installing the siding is really going to pay off in the end.
We've also made a great deal of progress lining the exterior mechanical cubbies and the east and west porch walls with Hardie Board panels. A stark contrast to the rough, weathered texture of the barn siding, the Hardi-Board is a crisp, white, smooth surface. Also in stark contrast to the barn siding, the Hardie Board installs quickly and easily with minimal fuss.
The major focus in the coming weeks will be finishing up the exterior cladding while work on the MEP rough-in continues inside. Check back for updates!

Electrical Rough-In
Posted on July 4, 2009We've started the electrical rough-in and things are really starting to take shape inside the house. The main breaker panel has been installed and wiring and boxes have been roughed in. Michael from Watt-1 has been leading the installation for the past several days and his expertise and efforts have been extremely valuable. Thanks Michael! We really appreciate everything you're doing.

A New Use For An Old Barn
Posted on June 25, 2009The barn siding was delivered Sunday night and the team has gotten to work sorting the wood, pulling nails, and ripping it in to straight, useable pieces. While this process is labor intensive, we're confident that the results will be worth it. The wood is a mixture of poplar and red oak from a barn in Chillicothe, Ohio. Special thanks go out to Jake Balzer Family with Balzer Farms for helping us with this effort. We really appreciate the quick turn around and delivery and we can't wait to show you the finished product.

Rigid Insulation
Posted on June 25, 2009With the exception of the area around the scuppers where we're still waiting on metal trim pieces, we've completed installing the rigid insulation and furring strips to receive the barn siding. The rigid insulation, generously donated by Owens Corning, will serve as an additional layer of protection against the elements and reduce the effects of thermal bridging through the studs. The furring will hold the barn siding away from the house in order to create an air space behind the wood. This principle is known as a rainscreen and it allows any water that gets behind the siding to drain out instead of becoming trapped. The air space allows the back side of the siding to dry out, reducing potential for rot.

This House Is For The Birds
Posted on June 25, 2009After taking a break for a couple of weeks to concentrate on graduation, we returned to the site and found a new tenant. A momma bird and her two eggs occupied a nest in the rafters at the northeast corner of the house. After consulting with some friends in the vet school, we decided not to bother her, and in turn she didn't bother us. She watched us work for about three weeks until one day the eggs hatched revealing two tiny, fuzzy babies. As of today, both babies have left the nest and we can go ahead and close up this portion of the house.

Momma and her babies...they grow up so fast!

Final Construction Drawings Submitted June 2 by 7pm
Posted on June 10, 2009All of our students came together over the last week or so to make a major last push on the submittals required by the Department of Engery for payment. Engineering team worked on their drawings, energy analysis, and narratives and our outreach team came together with the market viability section, communications plan, and dinner menus.
Our architecture team worked frantically through the weekend and the first couple days of the week to pull our Construction Drawings together. Neal worked from home despite being sick putting together our cost estimate while Steve worked away at our specifications. Dave and Deanna put the finishing touches on our drawings while Jared and Dan formatted everything into a consistent and catchy graphic package and Keoni and I revised, bookmarked, and threw it all together. Whew- what a lot of work!

Window Installation
Posted on June 6, 2009Following the completion of exit reviews this week, we've started installation of the windows and doors. Special thanks to Carol Meyer at Gunton Corporation for all of her help selecting and coordinating the Pella window order. She has been a true pleasure to work with and we appreciate everything she has done to help us. We really can't say enough good things about her.
The windows themselves are Pella Designer Series triple glazed units with a low-e coating and argon filling. We've already noticed that installing them on the west facade has made the house significantly more comfortable to work in during the afternoon hours.
The units arrived ganged together for ease of installation. Installation of the units couldn't have gone much easier. The instructions were really clear and the units themselves are so well designed that it was a breeze. The west end (105" wide x 8' tall, triple glazed...pretty heavy) went in first and the rest were a snap once we got in a groove. The next step will be installing the doors. Stay tuned!

Shimming the end of the east unit

Moving the west end in to position...somewhat heavy, but well worth it to avoid installing 6 individual units.

Exit Reviews Complete
Posted on May 29, 2009Yesterday, May 28th, our graduating students in the Masters of Architecture program completed their exit reviews. All of our team members did well and we're very proud of their success. Not surprisingly, the Solar Decathlon came up in many of the public lectures that they presented on a topic of their choice. Friends, faculty, and community members got to hear about our architectural designs in terms of interstitial space, framing methods, green design, moving customizable space, and more. Congratulations Neal, Steve, Dave, Deanna, Matt, Dan, Michael, Jared, Andrew, and Kris!

"If you find water inside now, call a plumber."
Posted on May 12, 2009The team has been hard at work on the roof membrane over the last week and we're now officially watertight. Day 1 was cut short by rain but we got a solid start on the east module. Day 2 was filled with sunshine and we were able to install all of the remaining insulation and most of the membrane. All that was left for Day 3 was pitch pockets and final detailing and we were finished by mid-afternoon.
Special thanks go out to Todd and Elvis from Phinney Industrial for helping us out with this effort. They were with us every step of the way teaching us how to properly install every piece of the roof. Their guidance was crucial to getting everything done efficiently and done right. We learned a lot and we had a great time in the process. We'd also like to thank Mike DeCrane at Phinney Industrial for setting everything up. We couldn't have done it without all of your help.

Housewrap installation
Posted on April 28, 2009
Saturday was a big day on campus with 95,000 plus fans across the street for the spring football scrimmage. Our task for the day was installing the housewrap (thank you again Owens Corning!) and taping all of the seams. It was a little breezy, but once we installed all of the button caps and taped all the seams, everything laid nice and flat. The entire house is now clad in pink and ready for furring, rigid insulation, and windows.

Thank you Owens Corning
Posted on April 28, 2009We'd like to take a moment to thank Owens Corning for all of their support so far. The rigid insulation and housewrap have been delivered and we've started the installation. We also really apprecaited the site visit from the Owens Corning team. We had a great time meeting everyone and their insight has been most valuable. As you can see in the picture, we're finished installing the standoffs for the solar panels on the roof and we've pre-cut all of the rigid insulation so we can lay it down quickly when the roof membrane gets here next week. We're looking forward to finishing the roof so we can start roughing in plumbing, electrical, and HVAC.

OSU Solar Decathlon Team featured in National Speech by President Gee
Posted on March 9, 2009On February 9, 2009, OSU President E. Gordon Gee delivered the opening address of the 91st annual meeting of the American Council on Education, the Robert H. Atwell Lecture, in Washington D.C.. Featured prominently in his address, "A Call to (Link) Arms", was the OSU Solar Decathlon Team:
"A couple of weeks ago, I spoke at a student-led event for our Solar Decathlon Team. Many of you likely have students working on this same project. The idea is for students to design, create, and build homes that are net-zero in their carbon footprint. Next fall, 20 student teams from across the country will transport their creations here to the Mall, where they will be re-assembled and judged.
What I especially admire about Ohio State's Solar Decathlon team is its composition: 60 members from 20 different majors. Engineers, artists, architects, accountants, marketing students, and more. That easy, ingrained, Millennial Generation approach to problem-solving is one of my great sources of hope for the future, by the way."
The OSU Solar Decathlon Team is honored to be named in a national address to leaders of higher of education and to be percieved as a vanguard, not only in the problems we aim to address, but also in manner in which we aim.

Center Module Framing WrapUp
Posted on February 8, 2009We are building our house in three modules that will be transported separately to Washington, D.C. Therefore, each module was designed to be stucturally independent. The center module was started first and is nearly complete. After it is finished we will be able to construct the adjoining walls on the east and west modules and install the connection components that will help hold the house together.

Roof Construction
Posted on February 8, 2009We are installing composite roof joists to span the 22' 8" north/ south dimension of our house. The composite I sections, composed of 2 x 4 flanges and an OSB web, can span longer distances than solid sawn lumber and are more materially efficient. Also, the direct bearing of the joists on the wall studs alleviates the need for a double top plate. The use of composite I joists along with advanced framing techniques reduces the amount of wood required to frame a house.

First Wall Raising
Posted on February 8, 2009The team recently raised the first wall on the Solar Decathlon House. The 2 x 6 wall section is on the north side of the house and will enclose part of the kitchen and entertainment areas. The section was built with advanced framing techniques using 2x6 studs placed on a 24" on center layout. Because the roof joists are designed to bear directly on the wall studs, the wall assembly requires no double top plate, reducing the amount of wood required. The 5 1/2" inch wall cavity can also accomodate more insulation than the 3 1/2" cavity of a conventional 2x4 stud wall, increasing R - values. Also, notice that openings are reduced on the north side as part of a passive strategy to save energy. The north side of a building gets less sun and is exposed to the most extreme winter winds, thus contributing to more heat loss. Therefore, reducing penetrations on the north facade can save on energy costs, especially in the winter.
Special thanks to Phil Arnold from the Knowlton School of Architecture (with camera) who is helping us document our build.

Pex Tubing Installation
Posted on February 8, 2009We had an unseasonably warm day to install the pex tubing for our radiant floor system. It was the only day in weeks that was above freezing so the tubing was quite easy to work with.
The pex will transfer hot water through the floor to heat our house. A radiant floor heating system has several advantages over a forced air system. It requires less energy to convey the heat and the thermal mass of the floor effectively stores and radiates it evenly throughout the entire house.
All hot water for the house will be pre-heated with an evacuated tube system located on the south facade. The glass evacuated tubes contain an element, sealed in a vacuum, that responds to the sun's energy and creates heat. This heat is then conveyed, via water or air, through a coil that transfers that heat to a hot water tank that separately supplies the radiant floor and domestic hot water. Pre-heating these water sources with the sun's energy requires the use of less electricity or natural gas.

Thank You and Good Luck
Posted on February 3, 2009Today we received a really lovely note from one of our major sponsors, Integrys Energy Services, that we wanted to share. Hopefully, the warm thoughts below will make you smile too. -Erin
Dear Solar Decathletes (and their faculty supporters),
Thank you for having us with you last week, to bask (if not in the sun) in the creative energy that you emit as you undertake a host of technical and organizational challenges to be completed in the remainder of the academic year (plus, evenings, weekends, and probably in to the summer).
Since I live in Ohio too, and work for a company with ambitious solar projects of its own, I am often questioned on how a cloudy state like Ohio can host effective solar projects. What the questioners often fail to realize, is that the spirit of environmental stewardship is not about how much resource you have, but about how well you make use of it.
Here in central Ohio , we may be a little poor in sunshine, but we have the great fortune of being illuminated by over 40,000 individulas from all over the world. These students and faculty members at OSU come here because they believe that a well-informed mind is a necessary advantage as we try to tackle new problems with new approaches.
For my part, and on behalf of Integrys, our investment in the OSU solar decathlon team is our vote of confidence that our collective interests are best served by supporting the creativity of youth who have not yet inherited our outdated notions. Under the tutelage of faculty not beholden to our commercial interests, we hope that you will contribute; to our industry, creativity and knowledge; and to our planet, health and prosperity.
Thank you , and good luck!

Posted on January 5, 2009We had a beautiful day on Saturday to install the radiant subfloor that was donated to us by Warmboard Inc. The subfloor is 1 1/4" thick and has grooves that will accomodate the radiant tubing that will heat our house. When people think of radiant floors they typically think of concrete. However, concrete would not be practical for a house that has to roll to Washington, D.C. We therefore chose a plywood panel system with an aluminum top layer that performs better than concrete at transferring heat evenly. The product consists of 5 4'x8' panel types that can be arranged to work with any floor plan, requiring little additional work.

Solar Decathlon on the Road to DC
Posted on January 5, 2009This Friday ten members of the team are headed to DC to attend NREL's pre-event workshop. We'll represent areas such as Instrumentation, Safety, Communications and generally go over rules issues with various staff members as they move around from team to team all day Saturday. While we're there, we're also going to check out some of the local resources for food, plants, lodging, and construction supplies. On Sunday we'll go down to the National Mall to check out the site with some of the organizers and discuss logistics and then drive back so that we can be back in class on Monday.

Construction Update: Floor Framing
Posted on January 2, 2009The floor framing is now complete and we are ready to install our subfloor. All energy for construction is being provided by a solar powered storage container loaned to us by Roger Beck and the Home BASE project. Appropriately, every element of construction is being powered by the sun.

We made our December deliverables!
Posted on December 17, 2008We had to submit our construction documents, project manual including specifications and cut sheets, health and safety plan and some photographs to NREL (National Laboratory for Renewable Energy) by 7pm last night. The culmination of work from the summer and entire quarter, we pulled things together to get everything in on time. We'll get feedback from NREL in January on how well we did before several of us head to DC for the pre-event workshop from the 9th through the 11th. -Erin

Winter Break
Posted on December 10, 2008As Ohio State's autumn quarter winds down we are ready to make great strides in two very important aspect of our project. First, December 16th is the deadline for Construction Documentation. We will submit our drawings and project manual to NREL electronically and wait for their feedback. Secondly, with classes over we can really get going on construction. As you may have seen the trailers are on site, leveled, and ready to go. We are waiting on our first lumber delivery and some free time to really get things kicking. We hope to make great progress during break.
P.S. Our WarmBoard delivery has arrived and is awesome stuff. It is part of the radiant floor system and will be key to keeping the house toasty all winter long. Special thanks for this great in kind donation.

American Electric Power
Posted on December 10, 2008Our team had a great opportunity to present to AEP Ohio last week. We shared with them our goals for the project and discussed forming a partnership to teach the Ohio community about the NEW power grid. Because our house will be net metered it is a perfect teaching tool and is able to demonstrate how the future Utility/Consumer relationship may work. Special thanks to AEP for their time!

Construction Camera and Trailer Delivery
Posted on November 12, 2008Exciting news on the construction front. We have made great strides to put up a construction camera to view our progress online. Special thanks to Derek, OIT, Facilities and RPAC staffers. We have also received final confirmation that our trailers will arrive this Saturday. Wahoo. This comes after tons of hard work from Steve and the entire design team. It certainly will be something to have the first pieces of the house at Ohio State.

KSA Faculty and Students Compete in Solar Decathlon
A team of Ohio State students will participate in the Solar Decathlon, a U.S. Department of Energy-sponsored competition to design, build and operate the most engaging, energy-efficient, solar-powered home. The Ohio State Solar Decathlon team is one of 20 teams that were selected from universities around the world. Each team receives $100,000 from the Department of Energy for their project. The competition challenges teams to develop a solar-powered home that meets various requirements in architecture, engineering, livability, comfort and power generation.
The two-year Solar Decathlon contest culminates in Fall 2009 when the fully solar-powered homes will be shipped to the National Mall in Washington, D.C. for display and final judging. Ohio State’s Solar Decathlon team includes students from various disciplines, including Architecture, Construction Systems Management, Engineering, Environmental and Natural Resources, and Political Science.
Architecture adjunct instructor Keoni Fleming, and Lisa Tilder, associate professor of Architecture, are among the faculty contributors.

Let's talk about the economy
Posted on November 9, 2008
Over the past few months, people in the sustainable energy movement have been afraid that the current economic situation is the final nail in the coffin. That’s it. That’s all she wrote. We didn’t even get past infancy, and we’re already done in.
This is not necessarily the case.
The truth is the rise of a more frugal lifestyle, like what is happening in the current economic crisis, is exactly what we need to push our movement to the next level. This is an opportunity, not a downward spiral.
It won’t be easy, though- there’s a lot to be done and not a lot of time in which to do it. We’ve got to step up, and not just in the movement. We’ve got to take charge on the local level, the state level, and the national level. People don’t want the “New boss, same as the old boss” anymore. People want something new, and it’s up to give the people what they want.
We’ve been given a chance to bring a new, sustainable lifestyle to the American people. It’s going to be a long, painful fight, but the price of action right now far outweighs the price of inaction for us, for our environment, and for our country’s future.
But I know what you’re thinking. “Gas prices are dropping, so things have to be getting better, right? We fought the fight, and now we won!” Three things. 1) It was conservation that dropped prices- a record 10% drop in demand, and if we go back to the way things were, the prices will do exactly the same. 2) CO2 emissions don’t operate on the market. And 3) Gas prices and utility bills are wholly separate entities. Just because you’re paying less at the pump doesn’t mean you’re paying less for electric or natural gas.
I’m going to repeat that.
Just because you’re paying less at the pump doesn’t mean you’re paying less for electric or natural gas.
We need to hammer (Literally and figuratively) this point home so that the desire to build more sustainable homes doesn’t go hand in hand with gas prices.

Construction Trailer !
Posted on October 27, 2008
The Construction trailer arrived at our build site last Thursday. It looks great with two solar panels collecting the power to build our house! Special thanks to Roger Beck and the HomeBASE program for allowing us to use the trailer. It is awesome to see something physical on the site--we are one step closer to D.C.!

Save the Buckeye
Posted on October 27, 2008Last Thursday the Solar Decathlon team had the pleasure of attending a great event put on by the Save the Buckeye Initiative of the Pew Environmental Trust. The night was full of inspirational and educational speakers discussing the science of Global Climate Change. We also had the opportunity to shoot a short interview with Save the Buckeye representative Tom Bullock. You can expect it on the web shortly! We look forward to working with Save the Buckeye on a solutions based forum this coming November. Stay tuned for more info.

Penn State Booth
Posted on October 20, 2008
The Solar Decathlon team will have a information booth at our build site, just south east of Ohio Stadium, during the pregame festivities for the Penn State vs. The Ohio State University football game this Saturday. We will be setup from 4-7p.m. so there is plenty of time to come and check out our progress, learn more about the house, and meet the team. As an added bonus we may be hosting a few members of the Penn State Solar decathlon team. Hope to see you all there.
Go Bucks!

School Tour
Posted on October 20, 2008The Outreach team needs your help! We are planning a Ohio School tour in which we travel to schools across the state (colleges, high schools, and elementary schools) to share the Solar Decathlon experience and demonstrate what we have learned about sustainable building to the next generation. We are taking a cue from President Gee and have set a goal to visit 20 Ohio counties. If you know of a teacher or administrator at your local school or you personally would like to help us setup such a visit please email me, Lucas Dixon, at dixon.294@gmail.com.

Building Site Approval!!!
Posted on October 9, 2008Exciting news today! After months of waiting we have been approved for a building location on central campus. The site we were approved for was our first choice and we are pleased to announce we will be constructing our home on a bit of green space adjacent to the South East corner of the Ohio Stadium. The green space is directly south of the McCracken Power plant auxiliary building. Congrats and thanks go out to all those that made this site a reality. We will have a booth setup on the space for this Saturdays football game against Purdue. Hope to see you all on game day!

Solar Tour
Posted on October 8, 2008Last Saturday, October 4th, the Solar Decathlon Team and sister project POD had the thrill of being part of the Ohio State University/Clintonville Solar Tour. It was great that visitors got to see and touch the nearly completed POD project and the hear about our plans for Solar House 1. Team members Kara, Kurtis, James, Mark, and myself described the two projects to over 50 visitors. Thanks to all those that came on the tour we enjoyed the experience greatly. Thanks also to Scott and Sarah for including us in the plans for the tour.

Govenors Gala
Posted on October 8, 2008Last Friday evening team members Erin, Bethany, Derek, James, Carson, Kurtis, and myself were honored to attend the 2008 Governors’ Gala, Green Energy Ohio's Solar Tour kickoff. The governor’s residence was a beautiful backdrop for the crowd of probably 200. The team had a display setup and enjoyed talking to the many friends we have made over the last year. As Kurtis said, "It is pretty amazing that we know almost half of the people here." Ms. Strickland, Mark Shanahan, and Bill Spratley all spoke at the event hyping up the Solar Tour. It certainly was a good time had by all as we acknowledged all the work done to get the Renewable Energy Portfolio Standard (senate bill 221) passed last spring. A new day has dawned in Ohio, a day powered by renewable energy. The Solar Decathlon Team is grateful for all the support we continue to receive from the GEO community. Special thanks to Sarah and Julie for putting together such a superb event.

Scarlet Gray and Green
Posted on October 8, 2008Last Friday afternoon the Solar Decathlon team attended the Scarlet Gray and Green Fair on central campus. It sure is amazing how much this event has grown. Seeing the event grow from where it was during my freshmen year certainly is a measure of how far sustainability issues have come. It was great to be back on campus interacting with students and seeing all our friends. Thanks to team members James, Derek, Bethany, and Kurtis for working the booth. Congrats and thanks to Stacy and Christie for hosting the greenest event on campus!

Columbus Green Building Expo
Posted on October 8, 2008
Last Thursday the Solar Decathlon team returned to the Green Building Expo for the second straight year. It is hard to believe that it was only one year ago that just a couple of students with big dreams showed up at the doors of the Green Building Expo hoping to absorb as much information from the sustainability community. We have certainly been welcomed into the sustainability family with open arms. We returned to the expo this year and had a very successful booth. Special thanks and congratulations to Meera for once again an outstanding event.
