It has taken a team effort from the design and construction to the operations of Stone 34 to make it truly a model for sustainable buildings. The project participated in a variant of the City’s Living Building Pilot Program and incorporated a range of leading-edge features: hydronic chilled beams which provide more efficient heating and cooling; heat recovery and exchange chiller system; phase change thermal energy storage tank; rainwater capture for non-drinking purposes; and large windows and complemented by LED lights with daylight and motion sensors. After its first year of operation, a design and operations review performed by the International Living Future Institute confirmed that Stone34
surpassed its targets in energy by 15% and water by 27%. The building has an ENERGY STAR score of 100 and has two LEED Platinum certifications.
