I have a project that is considering using the Core Performance Guide option for compliance with this credit. Our team has reviewed the requirements of the Core Performance Guide and we feel that the project is a good fit. Does anyone have any experience with this option for achieving the Minimum Energy Performance prerequisite and the Optimize Energy Performance credit?
