Modifications to ANSI/ASHRAE/IES Standard 90.1, the standard that forms the basis for energy efficiency regulations for commercial buildings, have entered the review and revision stage of development.
Proposed changes to the energy
- Amending the minimum energy efficiency requirements for standard-sized package terminal air conditioners and raising the minimum energy efficiency ratio to match packaged terminal heat pumps
- Modifying service water heating efficiency requirements for electric water heaters, heat pump pool heaters, and oil storage water heaters
- Changing the interior space-by-space lighting power density tables based on light level recommendations in the new 10th edition of IES’ Lighting Handbook, including spaces for seniors in permanent living facilities.
