To lower the contribution of a house to the greenhouse gases (namely CO₂) a homeowner decides to replace the 4" single glazing (acrylic/polycarbonate) aluminum frame without thermal break windows with 2" air-filled double-glazing wood/vinyl frame windows. The new windows have low emissivity (ε-0.1 on surfaces 2 and 3). The house has 195 ft² (18.17 m²) of windows, half of them are operable and the other half are fixed. All windows have 10" 14" (the total number of panes is 160). Estimate the reduction in the house's contribution to greenhouse gases during heating season if the homeowner goes ahead with the changes. Assume a five-month heating season with an average outdoor temperature of 32°F and indoor temperature of 70°F. The house is heated by a geothermal heat pump with a coefficient of performance of 3.5, in its heating mode. The electric company that supplies power to this house, on average, emits 1.1 pounds of CO2 per each kWh of electric power cunpliad

4. To lower the contribution of a house to the greenhouse gases (namely CO₂) a homeowner decides to replace the 4" single glazing (acrylic/polycarbonate) aluminum frame without thermal break windows with 2" air-filled double-glazing wood/vinyl frame windows. The new windows have low emissivity (ɛ=0.1 on surfaces 2 and 3). The house has 195 ft² (18.17 m²) of windows, half of them are operable and the other half are fixed. All windows have 10" 14" (the total number of panes is 160). Estimate the reduction in the house's contribution to greenhouse gases during heating season if the homeowner goes ahead with the changes. Assume a five-month heating season with an average outdoor temperature of 32°F and indoor temperature of 70°F. The house is heated by a geothermal heat pump with a coefficient of performance of 3.5, in its heating mode. The electric company that supplies power to this house, on average, emits 1.1 pounds of CO2 per each kWh of electric power supplied.
