As we move westward from the capital to the Pacific Northwest, Washington State showcases its dedication to environmental sustainability with robust legislation aimed at enhancing energy efficiency in buildings. This section explores the significant strides made by the state through its pioneering laws, the 2019 Clean Buildings Act (HB 1257), and its 2022 expansion (SB 5722). These laws exemplify Washington's commitment to reducing greenhouse gas emissions from buildings, a critical step towards achieving broader environmental goals.
Washington State
Washington State has been proactive in its pursuit of sustainability, particularly through legislation designed to promote energy efficiency within the building sector. This includes the influential 2019 Clean Buildings Act (HB 1257) and the 2022 Clean Buildings Expansion Bill (SB 5722). These laws set forth stringent energy performance standards specifically for commercial buildings, such as nonresidential spaces, hotels, motels, and dormitories, with the overarching aim of minimizing greenhouse gas emissions as effectively as possible.

Building owners are required to use the Clean Buildings Portal to verify building characteristics and submit compliance documentation. Tier 2 buildings must also participate in Benchmarking, Energy Management Planning (EMP), and Operations & Maintenance (O&M) programs.
These legislative measures in Washington State not only enforce compliance but also encourage building owners to adopt more sustainable practices, contributing to a significant reduction in the state's carbon footprint. The state's approach offers a model of how comprehensive energy efficiency legislation can drive environmental change while providing clear guidelines and support for compliance.
