The Buildings of Excellence Competition

The Buildings of Excellence (BOE) Competition is a $75 million competition that has distributed monetary awards over five rounds. Kicked off in early 2019, BOE recognizes and rewards the design, construction, and operation of resilience, climate-friendly multifamily buildings that are healthier for residents and their communities.

Designing and developing clean and resilient buildings that are good for both businesses and residents is at the core of this competition.

The honorees are visionary architects and developers who take the lead in achieving beautiful, zero-emission buildings that improve quality of life and inspire the industry to follow their example toward a climate-friendly future. Their projects are beneficial for the environment, highly profitable, and provide them a competitive edge in the marketplace.
