Efficient Windows A 2.0 m2 glass window is at a temperature of 20. ℃ on the inside surface and -20.℃ on the outside. The glass is 5.0 mm thick. At what rate does energy flow out through the window glass? Compare this rate to the energy flow through a double-paned window that has a 2.0 cm gap between the panes filled with argon gas.

Insulate the Roof A cathedral (sloped) ceiling in a house has a total area of 100. m2. The ceiling is covered with drywall (RSI 0.45), and the rafters are filled with insulation (RSI 40.0). The roof is sheathed with 1/2 in. plywood (RSI 0.63) and asphalt shingles (RSI 0.44). Calculate the rate at which energy is lost, assuming that the interior temperature is 20. ℃ and the exterior temperature is 2.0 ℃. Assume that energy losses from conduction through the wood rafters and from ventilation of the roof cavity are negligible.
