Our Services


We provide common-sense sustainable design.  This means adapting the level of sustainability to the project and its unique requirements.  Sometimes sustainability is the over-riding factor and drives the design.  Sometimes, the building program limits the extent to which sustainable design can be implemented.  And while we will not allow the function of the building or the safety of the users to be compromised, we will always incorporate sustainable principles as much as possible.  We are familiar with the U.S. Green Building Council’s green building certification system (LEED), the Environmental Protection Agency (EPA) regulations and national standards, and the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) standards.
