Consider a small house with walls 3.7 m high and each of four walls is 12.2 m long. A total of eight windows are placed in these walls, each with dimensions 0.9 m by 1.2 m. The windows are single paned with k = 0.78 W/m∙K and 0.6 cm thick. The walls have an RSI value of 3.4, which means they have RA = L/K = 3.4 m2K/W resisting heat flow. The heat transfer coefficients on the inside and outside of the house are 3 and 6 W/m2K, respectively. What percentage of total heat loss leaves through the windows? Neglect radiative heat loss.

Question
Consider a small house with walls 3.7 m high and each of four walls is 12.2 m long. A total of eight windows are
placed in these walls, each with dimensions 0.9 m by 1.2 m. The windows are single paned with k = 0.78 W/m∙K and
0.6 cm thick. The walls have an RSI value of 3.4, which means they have RA = L/K = 3.4 m2K/W resisting heat flow.
The heat transfer coefficients on the inside and outside of the house are 3 and 6 W/m2K, respectively. What
percentage of total heat loss leaves through the windows? Neglect radiative heat loss.
