Inefficient windows can negatively impact a building’s comfort, energy bills, and carbon footprint. But did you know that by optimizing the influence windows have on a building’s thermal energy demands -– minimizing sunlight on hot days and maximizing it on cold ones -– the size of a building’s HVAC equipment could be smaller, easing the transition to energy-efficient heat pumps? In this Better Buildings Residential Network peer exchange call, learn how windows can be instrumental to decarbonizing buildings and reducing U.S. annual energy use.
