Course Description

The 2022 version of 90.1 begins the Standard’s move to become 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 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 have direct energy impact. It is estimated that this standard will reduce energy cost by over 15% when compared to the 2019 version and over 48% compared to buildings built in compliance with 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 3-hour seminar is highly interactive, and your questions and comments are a welcome part of the discussion. The 3-hour version of this seminar will just cover the changes made in the 2022 edition. For new users to the code the 6-hour version offers an overview of the code requirements including the new changes. Together, we will explore ways that the 2022 edition of 90.1 can reduce energy use in buildings and how you can use these strategies to move toward net zero energy use.
