EquestThe 2013 California Energy Code (CEC) and the 2013 California Green Building Code (aka CalGreen) place new emphasis, and requirements, on building energy efficiency. In addition, many local jurisdictions such as Napa, Santa Rosa, Healdsburg, Sebastopol and others have further adopted the Tier 1 requirements of CalGreen. Tier 1 requires that all buildings exceed the CEC standards by an additional 10%. These stringent requirements necessitate the coordination between architect and engineer, early in the design process, to ensure the building will meet the CalGreen requirements.

This process can no longer be purely left to the energy consultant to “make it work”. In order to achieve the Tier 1 requirements architectural upgrades to insulation or glazing may be required. For this reason it is critical to have a knowledgeable expert on your team who can review these issues in the conceptual stage of your project.
