According to the United States Green Building Council (USGBC), in the United States alone, buildings account for:
- 72% of electricity consumption
- 39% of energy use
- 38% of all carbon dioxide (CO2) emissions
In addition, approximately 40% of air infiltration comes from the building envelope. Although doors account for a tiny percentage of the overall surface area of the building envelope, they are responsible for 11% of air infiltration.
This source of energy waste can be easily eliminated with the proper selection of doors and hardware.
