Green building is an approach to design, construction and operations that conserves resources while it protects human health. Green buildings use less energy, consume fewer natural resources such as water and forest products, and emit fewer pollutants into the environment. The District is a national leader in green building, which supports the vision set forth in the Sustainable DC Plan. By continually encouraging market transformation, funding research that promotes innovation, and collaborating with the community and private sector on best practices DC will remain a leader in protecting our planet.

Green Building Fund Grant Program

DOEE has created a Green Building Fund Grant Program to support innovative projects to “green” the built environment in the District. Grant projects include those that concentrate on research, data analysis, training, or engagement that help the District lead the way in enacting innovative policies that drive toward greater social, environmental, and economic sustainability for our city. Learn more about the Green Building Grant Program.

Net-Zero Energy Buildings

Net-Zero Energy (NZE) buildings generate as much energy as they consume, annually. These buildings minimize their greenhouse gas contributions, are cheaper to operate, provide healthier and more pleasant places to live, work and play, and will be increasingly important components of the District’s climate action plan. Clean Energy DC, the District’s detailed plan to reduce greenhouse gas emissions, calls for all new construction to achieve net-zero energy beginning in 2026. In light of this important goal, DOEE is committed to supporting projects pursuing NZE ahead of the statutory requirement.

Appendix Z of the 2017 DC Energy Conservation Code defines a net-zero energy building as “a highly energy-efficient building that produces on-site, or procures through the construction of new renewable energy generation, enough energy to meet or exceed the annual energy consumption of its operations.”
