This bill amends the Public Facilities Act by updating Section 213 of 61 O.S. 2021, which focuses on energy and environmental performance standards for state buildings. The amendments aim to enhance the construction, renovation, and maintenance of state buildings to improve energy efficiency, promote the use of environmentally friendly materials, and reduce reliance on imported energy sources. Key provisions include the establishment of specific energy performance requirements for heating and cooling systems, the necessity for a total building HVAC control system, and the requirement for life cycle cost analysis to determine the most efficient building performance.

Additionally, the bill introduces definitions for terms such as "licensed vendor," "new construction," and "state-funded entity," and mandates that projects funded by state appropriations must utilize licensed vendors for energy-related design and construction services. The Office of Management and Enterprise Services is authorized to create rules and standards to ensure compliance with these new requirements. The bill also emphasizes the importance of using local vendors and encourages the integration of renewable energy sources in new construction projects. The effective date for these changes is set for November 1, 2026.
