OK SB1285

Amends Oklahoma's Public Facilities Act to establish mandatory energy efficiency standards for HVAC systems in new construction and large-scale renovations of state-funded buildings, including higher education institutions and career technology centers (excludes public school districts and charter schools)

Requires gas-fired heating systems to achieve minimum 95% Annual Fuel Utilization Efficiency, ground source/geothermal heat pumps to meet specific performance standards (COP of 3.5 for heating, EER of 15 for cooling), and prohibits electric resistance heating as a primary heat source

Mandates life cycle cost analysis covering energy consumption, maintenance, and replacement costs over 25 years, with priority given to systems demonstrating lowest total life cycle cost and ground source/geothermal systems serving as the benchmark

Requires all new construction to incorporate total building HVAC control systems using non-proprietary software capable of scheduling, air quality monitoring, peak demand reduction, and integration with lighting/shading systems

Establishes preference for Oklahoma-licensed vendors, in-state bidders, HVAC units manufactured in Oklahoma, and engineers licensed in the state; effective November 1, 2026
