Supersolar Fresnel Lenses Power Team ABC’s Green-Roofed Sumbiosi Solar Decathlon House

<a href="http://www.sumbiosi.com">Solar Decathlon Team Aquitaine Bordeaux Campus</a> crowned their Sumbiosi house with a supersolar array of <a href="http://en.wikipedia.org/wiki/Fresnel_lens">Fresnel lenses</a> that concentrate 500 times more sunlight than the average system. Also equipped with a tracking mechanism, this project's solar efficiency soars through the roof, which, by the way, can be planted since a smaller area of solar panels are required to meet the home's energy requirement.

Team ABC's Sumbiosi Solar Decathlon house is very comfortable - even without air-conditioning

Fresnel lenses concentrate 500 more sunlight than conventional solar systems

A rooftop Ventec system also contributes to natural cooling and ventilation

Flexible design in the interior allows increases space when necessary

Unlike many of the homes, Sumbiosi provides a great deal of privacy

Using mostly natural materials, the team from France show tremendous respect for our limited resources

As you can see, there's no shortage of daylight in this home

The kitchen, dining and living area are combined in one compact but spacious area

Simple but bright furnishings contribute to the home's aesthetic appeal

This home produces almost twice as much energy as it needs

Greywater is cleansed with earthworms and sedentary layers and then reused to irrigate a green roof and wash the car!

The supersolar array makes space for the green roof, which also contributes to good air quality (conceptually - it has not been installed here in Madrid for practical reasons)

All materials were sustainably-sourced

Looks like a good spot for a nap, no?

The bedrooms are all modular in design

We love these fresh, clean lines and minimalist design

Rooftop panels double as shade

The home's cladding mitigates excess solar gain

The solar system produces electricity, hot water and a heat transfer fluid

Although this team's ranking is rather low, don't give up on them yet. This is a beautiful home erected by a team of hardworking kids.
