Lussier Community Center This 12,300 s.f. facility is designed to operate efficiently in an instructive, hands-on manner. The geothermal system is monitored online, providing feedback so that occupants can make adjustments in equipment use or in their own behavior. Operable windows are situated throughout, using natural convection to expel air through windows high over the central space. We anticipate that air conditioning will be needed only two weeks per year. The building detailing is crisp and straightforward, enhancing awareness by users of the elements of enclosure. It strives to merge an aesthetic sensibility with a participatory, ecological response to program, site and construction.
