As is tradition, The American Institute of Architects is celebrating the approach of Earth Day by announcing the winners of its 2023 COTE Top Ten Awards. Now in its 27th year, the annual program celebrates 10 projects displaying "integration of design excellence with environmental performance," according to an AIA description. Although the COTE program was created in 1997 by the AIA Committee on the Environment, the program formally shifted in 2017—rather than evaluating projects solely on "predicted performance," explains AIA, today's winners have also been judged on "post-occupancy data and narratives."

The 2023 COTE winners include affordable housing, a living laboratory, two offices, a nature center, three education projects, one infrastructure project, and a mixed-use project located across the United States. Each honoree was weighed against AIA's Framework for Design Excellence, a toolkit of 10 criteria seeking "to inform progress toward a zero-carbon, equitable, resilient, and healthy built environment," according to AIA.
