When your home has poor insulation, you use more energy to keep a comfortable room temperature. In some homes, over 60 percent of the energy used goes into heating and cooling - energy and money that is wasted if you can’t keep the unwanted air out.
Whether you’re improving your home or building one from scratch, insulation is one of the most practical and cost-effective ways to make your home more energy efficient.
With better insulation, you’ll be warmer in the winter and cooler in the summer without running energy intensive heating and air conditioning, cutting down your monthly expenses and your carbon emissions.

Impact 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 or heating per year) x (residential energy emission factor) / (12 months per year) = kg CO2e / month
Window 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 (residential energy emission factor) / (12 months per year) = kg CO2e / month
Total: Home Insulation + Window Insulation = kg CO2e / month
