The Net Zero Continuity Temporary Amendment Act of 2026 proposes amendments to the Green Building Act of 2006 and the Clean Energy DC Building Code Amendment Act of 2022. The bill aims to exempt certain District-owned and funded residential and nonresidential projects from adhering to net-zero-energy standards and modifies compliance requirements for these projects. Key changes include the introduction of new definitions, such as "aquatic center" and "natatorium," and the redefinition of terms related to construction codes. Additionally, the bill specifies that certain projects, including temporary buildings, additions under 10,000 square feet, and specific emergency facilities, are not required to comply with the net-zero-energy standard until final regulations are issued by the Mayor.

Furthermore, the bill amends compliance language regarding energy conservation and renewable energy requirements, allowing for certain exceptions until the Mayor's regulations take effect. It also establishes a timeline for the Mayor to issue final regulations on net-zero-energy standards and prohibits the use of on-site fuel combustion for thermal energy in new constructions and larger additions after December 31, 2026. The act will take effect upon approval by the Mayor and will expire after 225 days.
