Which component directly reduces a building’s Greenhouse Gas (GHG) emissions?

Which component directly reduces a building’s Greenhouse Gas (GHG) emissions?
A . High-efficiency HVAC
B . Double-glazed windows
C . Building Commissioning (Cx)
D . Native plant landscaping

Answer: A

Explanation:

A high-efficiency HVAC (Heating, Ventilation, and Air Conditioning) system can directly reduce a building’s greenhouse gas emissions by using less energy than a standard system. Since most energy production involves the burning of fossil fuels, which releases greenhouse gases, using less energy results in fewer emissions.
