US Green Building Council LEED Rating System
- LEED-NC, Platinum Level

This building achieved a Platinum rating under the LEED Green Building Rating System established by the US Green Building Council. Having participated in the charrette facilitated by the Rocky Mountain Institute, the firm designed a mechanical system based on ground source heat pump technology. Innovate use of large paddle blade fans reduce the amount of ductwork required in the building and, in conjunction with operable skylights, completely "flush" the building with fresh air when outside conditions permit. Extensive computer energy modeling shows that the building will yield annual utility cost savings of 60% versus a building constructed to current industry standards, while at the same time providing the occupants with individual control and operable windows. Incorporation of a wind turbine and solar photovoltaic cells were included in the design. As part of its mission to minimize the building's environmental impact, the firm - in concert with the design team - designed a "rainwater catchment" system to save and store rainwater on site, thereby minimizing any interruption of the natural water flow on site.
