Over 50% of a home’s annual energy consumption is through space heating and air conditioning. I upgraded my air conditioner to a model with a higher SEER rating and also got all the windows replaced with ultra-energy efficient, triple-pane, Energy-Star Certified windows. Heat gain and heat loss through windows are responsible for 25%–30% of residential heating and cooling energy use.
