A house built in the 1950s has 14.86 m2 of single-glazed windows. Estimate the heat loss (Watts) if the windows are replaced with double-glazed windows. Assume the indoor temperature is 20oC and the outdoor temperature is 0C?

Answer #1

Heat loss in double glazed window is less than that of single glazed window, because U value of single glazed window(5.6 watt/m2-K) is more. So heat loss will be more in single glazed window (for same dimension window) and less in double glazed window.

The external walls are 4.6 m in length and 2.7 m in height. the windows of the house occupy 32% of the bedroom's external wall area. Now, let's assume the walls are of weatherboard construction, with a total R-value of 0.46m2 k/w and the windows are single glazed clear with a U value of 5.9 W/(m2k). - Temperature difference = 9.3 degrees (outdoor= 10.7 degrees, indoor = 20 degrees) what would be the rate of heat transfer via conduction through...

Estimate the heat loss, due to conduction through a 1 square meter window if the inside temperature is 20°C and the outside temperature is 0°C. There is a stagnant layer of air on each side of the window, which makes the temperature difference across the 5 mm thick window only 1°C. This answer was 160 W. Estimate the heat loss by conduction through if it is double paned. Assume the stagnant air layer is between the two layers of glass...

In the first lesson we talk about the heat transfer that takes place in the human body, but the same types of transfer occur for any object. For the following question, use the dimensions and characteristics of your own home. It’s reasonable to assume that walls are thick enough to block direct heat loss to radiation (without prior conduction through the walls). Windows are relatively thin in comparison and conduct more heat than walls (i.e. a double-pane glazed window has...

A house with 200-m2 floor space is heated with geothermal water flowing through pipes laid in the ground under the floor. The walls of the house are 4 m high, and there are 8 single-paned windows in the house that are 1.2 m wide and 1.8 m high. The house has R-4 insulation (where R= 1/U is the overall unit thermal resistance(the R-value) and U is the overall heat transfer coefficient) in the walls and R-5 on the ceiling. The...
