We believe in designing buildings with purpose and beauty, sustainability, and suitability for the communities who will use them and the environment we all share. Sustainability has been a focus since our firm was founded in 1996 and is integral to our practice at every phase of design and construction. From reviewing siting, massing, and building systems at the conceptual phase to carefully specifying materials with low embodied carbon, sustainability is interwoven into all aspects of our work. As a signatory to the AIA 2030 Commitment since 2018, we strive for all projects to be carbon-neutral by 2030. We are proud to be among the 27 firms nationwide (15% of participating firms) that met the 70% energy reduction target for 2019.
