Air infiltration accounts for 25–60 percent of energy used to heat and cool a home—energy that is simply wasted.

Project Drawdown, High Performance GlassImpact metric calculations
To determine the carbon emission reduction estimates related to adopting a home and window insulation, the following calculation were performed:
Home insulation
((1/thermal resistance value before insulation improvement) - (1/thermal resistance value after insulation improvement)) x (surface area) x ((interior temperature) - (exterior temperature)) x (hours of cooling/heating per year) x (0.33 kgCO2e/kWh emission factor) = kg CO2e / monthWindow insulation
(((1/thermal resistance value before insulation improvement) - (1/thermal resistance value after insulation improvement)) x (surface area) + 1.08 x (air infiltration rate) x ((interior temperature) - (exterior temperature)) x (hours per year) x (0.33 kgCO2e/kWh emission factor) = kg CO2e / monthFor detailed calculations, references and assumptions, please see our Methodology page.
