My contribution to the Lighting Controls Association in December provides a summary of the new ANSI/ASHRAE/IES 90.1 energy standard, which is used by a model energy code by some jurisdictions while also serving as an alternate compliance path for the IECC.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) and the Illuminating Engineering Society (IES) recently published ANSI/ASHRAE/IES Standard 90.1-2019, Energy Efficiency Standard for Buildings Except Low-Rise Residential Buildings. This edition includes more than 100 changes from the 2016 version, covering administrative and enforcement, commissioning, mechanical, and lighting. For lighting, the new version adjusts interior power allowances, updates several control requirements, and introduces a simplified compliance method for office, school, and retail buildings.
