My lighting column for the November 2021 issue of ELECTRICAL CONTRACTOR tackles outcome-based energy codes.

Excerpt:

Codes are complex and sometimes confusing, sometimes requiring interpretation by the authority having jurisdiction. Because there is no national code, the country is a patchwork of codes. Energy codes only regulate design efficiency and are therefore limited to being predictive of energy savings based on estimates and modeling.

Going back more than a decade, some policymakers began working to simplify energy codes while addressing their shortcomings. Instead of a prescriptive-based (design within limitations, with some mandatory items) or performance-based (intensive modeling) compliance path, codes would evolve to be outcome-based, using a building’s actual measured/metered energy performance as the compliance metric.

It’s not an easy nut to crack, but the benefits continue to attract the interest of policy makers, particularly in California.
