REQUIREMENTS EXPLAINED

This credit rewards decreased regulated and unregulated energy usage below the ASHRAE 90.1-2019 requirements referenced in EAp2: Minimum Energy Efficiency, Option 1. To limit documentation level of effort, use the same ASHRAE 90.1 compliance method for prerequisite and credit compliance — either the prescriptive method or Appendix G Performance Rating Method (PRM).

For the prescriptive method, use the ASHRAE 90.1-2022 standard for maximum achievement of points, and to earn 4 New Construction points or 2 Core and Shell points automatically per EAc3: Enhanced Energy Efficiency, Option 1 Path 1 Case 2.
