The group Architectes Ingénieurs Associés (AIA) has updated an innovative system of energy storage and redistribution for buildings. Baptized AIR4POWER®, it has been the shared goal of a partnership with American startup LightSail (California).
Many buildings now produce energy from renewable sources. AIR4POWER®‘s solution allows this energy to be stored and redistributed in one of four forms: electricity, heat, cold, or compressed air.
Energy storage has always been a tricky problem, but the LightSail system has solved it with the aid of a compressed air system. The AIA (Architectes Ingénieurs Associés) group, based in Saint-Herblain, a suburb of Nantes, has allied itself with the Californian high-tech enterprise, LightSail Energy, which has developed the RAES (Regenerative Air Energy Storage) system.
LightSail’s technology improves on a technology that has been in use since the 19th century, in combination with “opportunity spaces” within buildings and foundations, which allows the AIR4POWER® system to achieve efficiency rates as high as 85 %.
Pays de la Loire—Silicon Valley link-up
This promising partnership between AIA and LightSail got underway as part of the overall Innovation Loire Valley project whose objective was to strengthen economic links between the Pays de la Loire and Silicon Valley, notably by means of learning expeditions. The next one is due to take place on 10 to 14 November 2015.
Before, Danielle Fong, co-founder of LightSail, will represent the company in Nantes this October at Greenweek.
