If you follow our twitter handle @pendulum_kc, you are aware that we are keenly interested in the advancement of solar technology. So much so that our office building is headed in the direction of being 75% independent of “the grid” by the end of 2012. That being said, we were excited to attend the Solar Decathlon in Washington D.C. this year and get up to speed on where solar is headed. One of the most exciting takeaways of the trip was the encouraging reality that the cost of solar panels as an individual component of a turn-key system is dropping rapidly, making this not so new technology more accessible to the masses. With the cost of panels at half of what it was in the not so distant past, the idea of solar as a viable alternative to conventional energy sources especially at the residential and small commercial level has caused many to take note.
Diversity In Delivery
Beyond advancements in technology and increased affordability we were equally excited about the diversity in design and delivery of the entries in the competition this year. Although there were varied levels of craftsmanship and execution, some of the design solutions were simply spectacular. The images below illustrate some of the variety in materials, massing, design features and aesthetic on display.
One of the most impressive aspects of the competition aside from the work itself was the judging criteria. The ten categories listed below focused almost exclusively on function, efficiency, and affordability; the question of whether your family can actually live a “normal” life in the space had to be addressed. Design and aesthetic was also taken into consideration but was clearly not the singular driving factor in the accumulation of points.
Competition Criteria
1.0 Architecture (drawings & specifications)
2.0 Market Appeal
3.0 Engineering (drawings & specifications)
4.0 Communications (website & public exhibit)
