Welcome to the New & Improved Reference Ace Beta!

1.1 Purpose

This manual documents the rules used for modeling residential buildings for performance-based compliance under California’s 2022 Building Energy Efficiency Standards (Energy Code) for residential and nonresidential buildings. This document explains how the proposed design, standard design, and reference design are established for a building and what is reported on the certificate of compliance (CF1R).

The 2022 compliance manager is the simulation and compliance rule implementation software specified by the California Energy Commission (CEC).

Documentation of detailed calculation algorithms is contained in the companion volume Appendix G, 2022 Residential Alternative Calculation Method Algorithms.

This reference manual documents the compliance analysis modeling rules for all aspects of the CEC’s Alternative Calculation Method (ACM) Reference Manual for single-family residential buildings. For modeling rules for multifamily buildings, please refer to the Nonresidential and Multifamily Alternative Calculation Method Reference Manual. This document does not specify the minimum capabilities of vendor-supplied software. The CEC reserves the right to approve vendor software for limited implementations of what is documented in this manual.
