Question

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 this external wall (both through the weatherboard wall area and the window)?

Could anyone help me with this question, please? Thank you so much
