The Net Zero Modification and Preservation Emergency Amendment Act of 2026 aims to amend the Green Building Act of 2006 by exempting certain residential and nonresidential projects from the requirement to maintain net zero energy compliance. The bill modifies the compliance requirements for various types of projects, including temporary buildings, additions under 10,000 square feet, and specific facilities such as police and fire stations. Additionally, it introduces new definitions related to aquatic centers and natatoriums, and it updates existing definitions to align with the Building Codes.

Furthermore, the bill amends the Clean Energy DC Building Code Amendment Act of 2022 by redefining net-zero-energy standards and clarifying the types of projects to which these standards apply. It also repeals section 6 of the Housing Production Trust Fund Act of 1988, which imposed additional net zero energy requirements on subsidized projects. The changes are intended to streamline compliance and support the construction of essential facilities while maintaining energy efficiency standards where feasible.
