HVAC/Water Equipment Efficiencies

2016 Title 24 CASE Topics

Measure Overview

The purpose of this measure is to update mandatory efficiency requirements for space conditioning equipment that appear in Tables 110.2-A thru K so the minimum equipment efficiency values are as stringent as the minimum efficiency requirements in ASHRAE 90.1-2013. Not every efficiency value listed in the tables in Section 110.2 will be updated. The Statewide CASE Team is proposing that eighty-two (82) values in these tables be updated. Most of these changes will update the minimum efficiency values for equipment that is already covered by Title 24.

This proposal would also add minimum efficiency requirements for the following equipment that is not previously covered by Title 24:

  • Propeller or axial fan evaporative condensers
  • Centrifugal fan evaporative condensers
