How Building Decarbonization Can Transform HVAC

ASHRAE Journal, vol. 63, no. 9, September 2021

 
Buildings in the US account for 40% of carbon emissions. Eighty percent of that is from electricity use and the remainder is from the combustion of fossil fuels for heating and other uses at the building. As many states, utilities, and large corporations are moving to get electricity from clean, carbon neutral sources, it is clear that electricity is becoming the carbon free choice of energy for many in the US. Buildings that use natural gas and other fossil fuels for heating will be stuck producing carbon emissions, as electricity becomes increasingly carbon free. Natural gas can now be replaced with electric systems that provide equivalent or better service. An all electric building coupled with a renewable or carbon free source of electricity is considered to be a decarbonized building.
