Course Description

The 2022 version of 90.1 begins the Standard’s move toward becoming a Net Zero Carbon Emission Code by 2031. This edition adds a new section, Chapter 11 Additional Efficiency Requirements. These additional requirements are above the prescriptive requirements but contain many options for compliance that demonstrate a possible path to net zero buildings. The mechanical section introduces the Total System Performance Ratio (TSPR) as an alternate path for compliance. This offers a whole new path to compliance using a system approach; not prescribed efficiency. The 2022 edition also includes a new informative appendix that can be used with Appendix G if a rating authority wants to use metrics other than energy cost, such as carbon. Appendix G also added Appendix J with performance curves to be used for part load equipment performance.

The 2022 standard is a departure from business as usual. Even the Purpose has changed to include sites. It still has the prescriptive requirements with 89 addenda, 39 of which focus on direct energy impact. It is estimated that this standard will reduce energy costs by over 15% when compared to the 2019 version and over 48% compared to the 2004 version. Many of the methods used in the 2022 version to obtain these savings can be applied to the edition of the code currently used by your rating authority to show energy savings beyond your current code.

This 6-hour seminar is highly interactive, and your questions and comments are a welcome part of the discussion. Together, we will explore ways that the 2022 edition of 90.1 can reduce energy usage in buildings, and how you can use these strategies to move toward net zero energy use.

Learning Objectives:

• Describe the background and development of Standard 90.1, requirements, and compliance paths.
• Describe updated requirements from previous versions of the Standard for key technical sections of the Standard: Lighting, HVAC, Building Envelope, Power, and Other Equipment.
• Describe the changes made to the Standard in 2022 with the context for understanding and applying the changes.
• Apply the new paths for compliance; Total System Performance Ratio (TSPR).
• Practice using new Section 11, Additional Efficiency Requirements.
• Explore ways to improve system energy performance in buildings.
