Martyn Dodd will provide an overview of the building envelope requirements affecting nonresidential construction under California’s 2013 Title 24 Energy Efficiency Standards, which will take effect January 1, 2014. Mr. Dodd will highlight revised and new envelope requirements for 2013.

The California Energy Commission estimates the 2013 nonresidential standards are 30% more stringent than the currently applicable 2008 standards. This educational program assumes basic familiarity with the existing standards. If you are not familiar with the standards, we advise you to visit the California Energy Commission’s Title 24 web site at http://www.energy.ca.gov/title24/

About the Presenter
Having written software used in California for Title 24 energy code compliance over three decades, Mr. Dodd is principal of EnergySoft, a Bay Area company that specializes in performance based energy analysis. He is one of the original authors of the 1992 Nonresidential Alternative Calculation Method (ACM) manual, which defines the rules for code compliance software. It has become the model for both national and international code compliance software procedures.

Mr. Dodd is the author of the EnergyPro, COMPLY 24, and Perform 2001 software programs, which are used extensively throughout California for code compliance. He also wrote the NECB Comply software for the government of Canada, used for performance-based code compliance with the Model National Energy Code of Canada.

Learning Objectives

At the conclusion of the program participants will:

1. Have gained a summary understanding of the changes to the prescriptive building envelope requirements of the California 2013 Title 24 Nonresidential Building Energy Standards.

2. Be able to describe at least two mandatory requirements for nonresidential building envelope that are new or revised under the 2013 Title 24 Nonresidential Building Energy Standards.

3. Understand revised prescriptive requirements in the 2013 Title 24 Nonresidential Building Energy Standards for fenestration U-factor, solar heat gain coefficient, and visible transmittance.

4. Be able to describe revised prescriptive requirements in the 2013 Title 24 Nonresidential Building Energy Standards for cool roofing materials and minimum skylight area for large enclosed spaces.
