North House
One of the key goals of the Solar Decathlon is to raise awareness among the general public about renewable energy and energy efficiency, and how solar energy technologies can reduce energy usage. One of the primary ways this is achieved is through public tours of the individual houses, including the North House. There were a few questions that we, Team Ontario / BC receive quite often during tours - the questions and answers are documented here:
What is the total photovoltaic capacity of the house?
The total capacity is 14 kW. This can be broken down to 8.3 from the Roof, 2.1 on the East Façade, 2.1 on the West Façade, and 1.5 on the South Façade.
How do the exterior blinds work?
The exterior blinds work with the highly insulated glass windows to accept heat from the sun in the winter, and reject heat during the warmer months. They are automated using data from sensors on the interior and exterior of the building, the location of the building, the time of day and the time of year. The user can override this optimized automated system according to their preference. During inclement weather, the blinds are designed to go to the horizontal tilt position when the wind speed reaches 8m/s and when wind speeds reach 12 m/s they retract fully.
What is the purpose of the ceiling?
The ceiling is a sculptural solution for light diffusion and sound absorption. The form helps to loosely define the spaces in the open living area. There are 5248 individual cells of varying sizes.

What a race in the end. At first there was the announcement of the engineering contest. Darmstadt was placed 4th place so we all did not know, here were are placed compared to the first team Illinois (they became seventh). And then the announcement of the overall winner: We all were standing there waiting just to hear Team Germany once … As it took really long … the announcement began with 3rd over 2nd to first … the eagerness was unbelievable. And in the end we knew … we did it again!

Advisor Jonee Kulman Brigham reports on the first rate ICON Solar House lighting design.This morning, the DOE announced that University of Minnesota had won the lighting design competition which considers "designing functional, energy-efficient, and aesthetically pleasing lighting systems" - both for daylighting and electric lighting. Scoring 72 out of 75 possible points, the team was complemented on the simple controls, use of daylighting, black-out shades, electrochromic glass shading, extensive use of solid state LED lights, the east porch lighting, the appearance of the lit house at night, and for creating a lighting design that worked with the ventilation system and climate.
Rose Lin, co-leader for the interior design team in charge of lighting collaborated with Joe Messier, student commissioning leader on integrating electric lighting and shading with the daylighting approach. Joe modeled the integrated result in both daytime and night lighting mode in a 3D rendering program to help the team refine the lighting scheme. Professional lighting and daylighting experts contributed advice through a series of design reviews and meetings.
The team chose a selective and strategic approach. According to the project manual, "The ICON House is designed with features that offer maximum efficiency of light around the house, interior and exterior, natural and artificial. Integration of technology and sustainability is balanced with traditional lighting strategies by using electric lighting with a clearly defined purpose, and selective use of daylight to enhance areas within the home. As a result of the selectivity, the entire electric lighting budget is under 500 watts for both interior and exterior." That last point was illustrated by a vase of five, 100-watt incandescent bulbs that was displayed for visitors in order to make the savings more tangible.

The choice of lighting sources points a new way forward. A U.S. Lighting Market Characterization Report prepared for the EPA in 2002 found that average residential lighting use consisted of 91% incandescent lamps, 9% fluorescents, and a negligible amount of LEDs. The ICON Solar House shows that warm, familiar and pleasing lighting design can come from a majority of LEDs, a few fluorescents, with no need for incandescents.
The ICON Solar House also illustrates that strategic placement and shading of windows can result in daylighting that reinforces the functionality and mood of various places in the home. The narrative by Rose and Joe in the manual states, "Along this east west axis a variety of daylighting approaches are taken from dramatic to tranquil, creating three zones that reflect the living activities within each zone." The kitchen area is filled with light in the morning from the large east windows that visually connect it to the dining area on the porch. If the light becomes too much, the electro chromic glass can be set to tint, reducing glare and solar gain, while retaining view. In the central dining area, large south windows capture moving sun angles and views of the south deck. In the living and workstation areas to the west, north clerestories and a modest sized west window, limit solar gain and glare while providing ample indirect north light for the more tranquil activities of reading, watching movies, or working at the computer. Low window openings at the south and high north clerestory window openings enhance natural ventilation.

TEAM BeauSoleil

WASHINGTON D.C. -- Two years ago, a team of architecture and engineering students from the University of Louisiana at Lafayette set out to build a sustainable, solar-powered home. They accomplished their goal – the BeauSoleil Louisiana Solar Home.
The home has been at the National Mall in Washington, D.C. since early October to compete in the 2009 U.S. Department of Energy’s Solar Decathlon. It’s the only team from Louisiana to ever compete in a solar decathlon and its among 20 teams from across the globe competing in this year’s contest.
Tomorrow, teams will celebrate their accomplishments with an awards ceremony at 8 a.m.
TEAM BeauSoleil from UL Lafayette is celebrating its first place win in Market Viability awarded earlier this week. A jury evaluated the homes on the following criteria:
• Livability – How well the home fits the specific needs of a targeted homeowner and whether it is a safe, comfortable, and convenient place to live,
• Buildability – Whether the home can be built efficiently at a cost-competitive price and constructed the way the team intended it to be built, and
• Marketability – How well the house’s curb appeal, interior appeal, quality craftsmanship, as well as its sustainability features and integration of solar technology, offer potential homebuyers a good value.
TEAM BeauSoleil scored 97 out of 100 possible points.
“We paid a lot of attention to what our culture is all about – our climate, our kitchen,” said Gretchen Lacombe Vanicor, project manager. “We knew from the beginning we had to make this home for the people of Acadiana and Louisiana.”
The Department of Energy will host the official awards ceremony Friday morning. The Engineering Award along with the first, second and third place overall winners will be announced. In addition, a People’s Choice Award will be announced. To vote for TEAM BeauSoleil, text HOUSE76 to 99503. Voting polls close at midnight tonight.

Solar House Team
In the spirit of education, I've compiled a list of the top 10 questions we receive during public tours. If we added some new signs, we could probably reduce the amount we have to talk by about 90% or just send the 21 year old team members bar-hopping for the day.
In the spirit of being tired after a few long weeks of work, we've also added the responses we'd like to give to mix things up a bit...
1.
What is the wood the cabinets are made out of?Real Answer: It's actually manufactured from reclaimed sorghum straw and low VOC, no formaldehyde adhesive. It extends our design concept (expanding horizons) because of the long straight lines in the grain, and is a green material from the Midwest as well.
After a Long Day: "It's actually pure magic." We'd offer a longer, more creative explanation, but we'd be hoarse since we get this one from almost everybody.
2.
What are those things on the walls?Real Answer: Those are custom made lighting fixtures that we installed efficient LED lighting in. They're made entirely from recycled steel and glass as well.
After a Long Day: "Take a stab at it...they are plugged in to the wall and giving off a warm, yellowish glow that happens to
light up the area..."
3.
How do you water the plants?Real Answer: Our custom automation system (Chameleon) has soil moisture content sensors that it reads. If the soil is to dry, a soaker hose running underneath the plants will turn on and water them until the desired content is reached.
After a Long Day: This one depends. If you just got the 10 minute pitch on the automation system, we're likely to ignore you since we already talked about it. If you skipped the pitch on automation, we're likely to ignore you because you'd know the answer if you had listened. Guess it doesn't really depend.
4.
Are these cement countertops?Real Answer: We chose concrete countertops due to their durability and because it's recyclable. It also helps us to keep the price down as it's cheaper than other common counter materials such as granite.
After a Long Day: That would be awfully tough since cement is just a binding agent. If you mix it with aggregate and water, you get the wonder material that we used.
5.
What are the fins on the sides of the house?Real Answer: They're called louvers, and are rather popular in other countries and on some larger commercial buildings here. Because of the changing angle of the sun through seasons, they block direct sunlight during the summer and allow most to pass during the winter.
After a Long Day: We have to drive our house down the highway to D.C. These are for aerodynamics to make it easier on the truck.
6.
Does the drain work?Real Answer: Yes. The shower area is sloped down to it to make sure we don't have standing water. As it runs the length of the bathroom, it can handle the flow from the shower, and it's slightly dammed as well to keep water from spilling over. We chose this type of drain due to the universal design aspect of the home...anybody can get into the shower.
After a Long Day: No. The company decided to mass market a product that doesn't work and we thought we'd support them because we respected the brash attempt.
7.
Why is there a screen behind the mirror?Real Answer: It is actually an energy saving measure. By getting headlines, weather, sports scores, stocks (et al) through a very low power draw device, you're minimizing the usage of traditional, high power draw devices such as a TVs or computers. Plus, it's awesome.
After a Long Day: Toilet + Shower + TV means all you need is a beer cooler and you'll never have to leave the bathroom. We're only one step away...
8.
What are the tubes on the roof?Real Answer: We generate our electricity through the flat PV panels on the roof. The tubes allow us to heat water without using our electricity, which is far more efficient. There is a copper tube that goes into the manifold at the top, which in turn heats a closed loop of a hydroglycolic mixture. That in turn radiates up and heats the domestic hot water for the home, and the water used for our hydronic radiant floor system.
After a Long Day; They're huge Pixie Sticks. Go try to eat one.
Okay, so it's not quite the top 10 list I promised, but it's been a long day ;-).
In all seriousness though, we actually like answering questions. We've worked on the project for the past two years to raise public awareness and because we love the idea behind it. Keep asking questions, and we promise to give you the real answer (though you may have to sit through the others first).

Team Ontario / BC celebrated Canadian Thanksgiving tonight in our hotel. It was so nice to sit down to eat with the whole team, and with the friends and family who have journeyed to Washington to support our Solar Decathlon entry. Dinner was served at 10:00 pm - after lockdown on the mall - so that everyone on the team could participate.
