Life-Cycle Climate Performance Metrics and Room AC Carbon Footprint
The comprehensive carbon metric accounts for the fact that AC electricity use and the integrated carbon intensity of that electricity can be up to 48% higher than estimated using national “average” assumptions. Taking real-world operating conditions and the actual carbon intensity of electricity generation, transmission, and distribution at the end-use into consideration provides for a more accurate assessment of the significant climate and economic benefits from energy efficiency and power grid investment.This article was published in ASHRAE Journal, November 2018.
