Who we are

The Committee on the Environment (COTE®) is an AIA Knowledge Community working for architects, allied professionals, and the public to achieve climate action and climate justice through design. We believe that design excellence is the foundation of a healthy, sustainable, and equitable future. Our work promotes design strategies that empower all AIA members to realize the best social and environmental outcomes with the clients and the communities they serve.

ULI Resources on Renewables & Reuse

By Julie Hiromoto FAIA posted 13 days ago


Urban Land Institute (ULI) recently issued two reports that the COTE community should take notice of: Renewable Energy Strategies for Real Estate and Resilient Retrofits: Climate Upgrades for Existing Buildings. 


In my 2019 Congressional Testimony, before the House Committee on Energy and Commerce, I reiterated the importance of both energy efficiency and phasing out fossil fuels in order to meet the Committee’s own goal of a zero carbon economy by 2050. The question is not one of energy efficiency or fuel source, but that fully electric, renewably powered buildings cannot be successful without first curbing consumption. Architects and our project partners have made great strides in reduction, absorption and conservation design strategies and operational policies. And the world of renewables is complex, with local and regional nuances, and may require specialized expertise. If you tried to dip your toe into these waters 10 years ago, you’ll see that the landscape has completely shifted. Renewables are the fastest growing energy source and now more cost effective and achievable- even in Texas, where 40% of our power is wind, the highest percentage of any state. Renewable Energy Strategies for Real Estate is a foundational report that outlines the business case, financing mechanisms, and risk mitigation strategies for both onsite and purchased renewable power. 


After returning from the United Nations Climate Conference in Glasgow, Scotland (COP26), I flagged existing buildings as one of four big opportunities for architects to do more. It’s not just about making our existing building stock more efficient to save money, enhance comfort and reduce our GHG emissions, but reducing risk and vulnerability of existing real estate assets in the face of more frequent extreme weather and natural disasters. By retrofitting existing buildings that may otherwise fall into disrepair or abandonment, we can also address housing and infrastructure limitations resulting from constricted supply chains, labor shortages and climate migration. Our existing buildings are a critical part of the solution, and Resilient Retrofits outlines the cost benefit analysis of retrofit, including equitable design, policy and finance perspectives.
