Insulate Your Home

When your home has poor insulation, you need to use more energy to keep a comfortable room temperature. Up to 60 percent of energy used to heat and cool a home is wasted when you can’t keep 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 buildings more energy efficient. You’ll be warmer in the winter, and cooler in the summer without having to run heaters, fans or air conditioning units that contribute unnecessarily to carbon emissions and your monthly expenses.

  • 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/heating per year) x (0.33 kgCO2e/kWh emission factor) = 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 (0.33 kgCO2e/kWh emission factor) = kg CO2e / month
