The expanded, revised version of the energy standard focuses on energy-saving measures the Standard 90.1 committee hopes will help designers create more energy-efficient buildings. The newly updated ANSI/ASHRAE/IES Standard 90.1-2019, Energy Efficiency Standard for Buildings Except Low-Rise Residential Buildings, includes new and updated equipment efficiency requirement tables and a clearer compliance path for renewable energy treatment.

The latest edition of ASHRAE’s most prolific energy standard includes more than 100 updates since the last edition was published in 2016. 2019 Update Focuses on Energy-Saving Measures, Addresses Fan Efficiency, Pump Requirementsįrom HVAC&R Industry Newsletter, October 31, 2019
