A-For a general office room, the exposed wall (with a window, outside winter type) construction is 19 mm plaster outside (cement and sand) and 20 cm brick (building). The area of the window is 50% of the exposed wall. Calculate the heating load required for the office caused by the wall and window. Take Tout-5 °C and Tin-25 °C, exposed wall height=3 m and width=5 m, Inside and outside still air thermal resistance fi= 9.37 W/m²°C and fo= 34.1 W/m2 °C respectively. (6 marks)
