Heat Conductivity

When considering the design of houses, the heat conductivity by walls, roofs, and the floor plays an significant role. The heat conductivities (λ) of some building materials are explained in Table 1.

Calculate the heat flow by a wall of 150 m2 (typical of a single-family house in Central Europe) that consists of a brick layer with a thickness of d = 24 cm and by the same wall that consists, though, of a brick layer with a thickness of d = 36 cm. There is a temperature of 25°C inside and 10°C outside.
