Through this presentation, attendees will learn about the tools available to assist in energy modeling and documenting compliance with 90.1 Appendix G Performance Rating Method, how Denver is using these tools now for compliance with the 2022 Denver Energy Code, and what is coming in the future.
For jurisdictions and energy modelers alike, more stringent performance-based building energy codes mean that compliance is centered in energy modeling, documentation, and verification that a model was created correctly. Moreover, a balance must be struck on the time spent on compliance. To address this challenge, several tools were developed to determine project compliance based on energy model results and to also help determine model inputs and provide a framework for performing model reviews.
The workflow and tools discussed will focus on the application of ASHRAE Standard 90.1 Appendix G Performance Rating Method and the 2022 Denver Energy Code. We will overview two U.S. Department of Energy Excel-based tools, the Performance-based Compliance Form and the Companion Tool. The Compliance Form streamlines the documentation for Appendix G as written and the Companion Tool provides documentation if the Appendix G methodology is customized by a jurisdiction for compliance or by an entity for determining incentives. These tools integrate into the modeling workflow to streamline the whole building energy modeling and documentation process. Attendees will also learn about the energy model review process for Denver.
Additionally, we will look to the future of performance-based compliance tools, emphasizing projects that enhance the usability of energy modeling for code compliance such as ASHRAE 229P and web-based tools.
