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, 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 2.0 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 Fund Grant Program.
Net-Zero Energy Buildings
Net-zero energy (NZE) buildings generate as much clean 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. DC is taking an efficiency first approach to defining NZE buildings, ensuring that they first focus on driving their energy consumption as low as possible. Renewable energy can be generated either on- or off-site, acknowledging that not all buildings can supply their own energy.
The Clean Energy DC Building Code Amendment Act of 2022 calls for the District to adopt an NZE building code that applies to the new construction or substantial improvement of any building subject to the Commercial Provisions of the DC Energy Conservation Code, including commercial buildings and residential buildings taller than 3 stories.
Appendix Z is the District’s current, voluntary NZE building code. It is an alternative pathway for buildings to comply with the 2017 DC Energy Conservation Code. Appendix Z defines an NZE 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.”
