This training provides an overview of the ASHRAE Standard 90.1-2022 Performance Rating Method in Appendix G as adopted by the 2025 New York State Energy Conservation Construction Code. The course explains the proposed and baseline modeling framework, including use of the stable Appendix G baseline, and focuses on the requirements most likely to affect compliance results, including building envelope, HVAC, lighting, service water heating, and renewable energy. The course also explains the distinction between regulated and unregulated loads.

Key topics include thermal block development, baseline HVAC system selection and sizing, ventilation and fan power, equipment efficiency, thermal bridging, fenestration, infiltration and shading, lighting power and controls, service water heating, purchased heating and cooling, and requirements for plug, process, and other equipment loads. The training also covers the compliance calculations and allowed metrics for demonstrating compliance, including the New York State site-energy metric, and explains how prescriptive renewable energy requirements are incorporated into the performance calculation. The training also addresses application of Appendix G requirements to different project scopes where applicable.
