The room shown below, at a latitude of 40° N on the 15th of January, and solar time of 12 hrs. The room is maintained at 22°C dbt, the ambient temperature is 45°C dbt, and the adjacent building (conditioned building) is maintained at 30°C. The wall is made from common bricks of 20cm, 2cm of gypsum plaster, and a 2.5cm cement layer from inside and outside. Calculate the heat transfer by the walls, if the convective heat transfer coefficients for inside and outside are h_i = 11.5 W/(m^2)K and h_o = 27 W/(m^2)K respectively. For wall color take K = 0.85 and for ΔT use the following relation ΔT = (CLTD + LM)K + (25.5 - Ti) + (To - 29.4).
