Our work in sustainable and energy conscious design is an expression of our principles. To achieve solutions specific to context, we search for harmony with climate and topography. We take care that our sites are developed with minimum disruption of their inherent qualities and of their surroundings. We promote the effective use of regional materials, conservation of water resources, and healthy interiors with daylight and views. We believe that designing with climate means more than energy efficiency; it enriches architecture, offering a better quality of life and the enjoyment of place. Our long term commitment to environmentally sensitive design has allowed us to reach beyond local boundaries.

In the early eighties, we started exploring earth sheltered and solar strategies. The Heywood Residence was among the winners of the Passive Solar Design Competition, sponsored by the Arizona Solar energy Commission. In the same period, the firm produced An Energy Performance Plan for Arizona Buildings, under a research grant from the U.S. Department of Energy through the Arizona Architects Foundation. Subsequently invited to AIA's national Energy Committee, Hugh Knoell contributed for three years in formulation of the national AIA Energy Action Plan. Recognizing the firm's work, the National Council of Architectural Registration Boards (NCARB) selected our House on the Edge of a Mountain Preserve as a case study in conjunction with Renzo Piano's Debis Tower for its energy-conscious design monograph:
