The Solar Decathlon Europe – An Exciting, if Wet, Experience

The Nottingham H.O.U.S.E

The experience of serving as a sponsor of the University of Nottingham Solar Decathlon H.O.U.S.E. is one, I am sure, none of us who were directly involved will soon forget.

This was the first Solar Decathlon held outside of the United States, and Madrid, Spain served as the host. The University on Nottingham was keenly interested in participating and sought a sponsor who manufactured all the primary components they would use in the house. Saint-Gobain was the obvious choice, given the scope of our interior and exterior products that create and promote energy efficiency and sustainability. The Saint-Gobain companies that participated included Isover, British Gypsum, Saint-Gobain Glass, Solaglas, Ecophon , International Timber, Pasquill and Greenworks (Saint-Gobain Building Distribution). The Nottingham H.O.U.S.E design utilized an L-shaped, modular design that could be worked into rows, terraces or stacked.  The Team’s goal was to design and build an affordable, energy efficient house that would appeal to the general population.

During the construction week in Madrid, the H.O.U.S.E team lost several days due to the worst rain storms to hit Madrid in 50 years. The H.O.U.S.E. location was in the lowest part of the Villa Solar, below the water table, and the rain just poured down onto the site while construction was underway.  As the crane was placing the house modules, it slipped and significant damage was sustained.  There was no way to repair the damage to the house completely so the students made some adjustments in order to meet the construction deadline to compete.  While challenges such as this were a learning experience, the judges did not take the adversity into consideration.

The Nottingham team was the youngest team in the competition, with second and third year students while the other teams were fourth year or graduate students. The team that won, Virginia Tech, had participated in two previous Decathlons with the same house.  By perfecting their design and incorporating the feedback they received, they were able to return and win.

We are proud of what the students we sponsored achieved in the design and construction of the house, how they worked through the challenges and emerged able to compete.  They received second place in the sustainability section and were voted the most livable house by the visitors to the Solar Decathlon.  Several Spanish developers, as well as English developers, are interested in using the design for future construction. 

As part of our sponsorship, Saint Gobain provided training at our facilities to teach the students how to construct the house using our products.  This project wasn’t just about the H.O.U.S.E, it was about creating an energy efficient concept that could be mass produced by builders, the training and the solid hands-on skills the students gained that will set them apart when they enter the workforce. 

As for future participation in the Solar Decathlon, the expertise that was gained by participating would be in vain if the University of Nottingham did not participate in future Solar Decathlons especially since the same students could perfect the H.O.U.S.E which was very well received by developers and potential homeowners – the audiences that really count.
