The exterior wall construction is as follows from exterior to the interior: Face Brick (100mm) Air Space (19mm) Continuous extruded polystyrene Insulation board with density of 56kg/m³ (38mm) Building paper (vapour permeable air barrier) Plywood sheathing (12.5mm) Wood stud 42mm wide, 400mm on center, Mineral fiber insulation (92mm) (You can assume the ratio of wood studs to mineral fiber insulation is 1:4.) • Vpour Barrier (0.15mm) Gypsum board (12.5mm) There are two 1.5m x 0.8m windows with two layers of 3mm glasses separated by 92 mm of air space. There is a 2.1m x 0.915m solid hard wood door with the thickness of 50mm. The roof construction is as follows (from interior to exterior): Plywood board (25mm) Vpour Barrier (0.15mm) Expanded polyurethane Insulation (102mm) Built-up roofing (9.5mm) Below the slab is a conditioned space with the same temperature as your room and you can assume there is no heat loss through the floor. The inside temperature is set to 20°C and outside is -10°C. . . Find the RSI value of each assembly. Find the temperature at each interface within your exterior wall, window, door, and roof assembly. Draw temperature gradient of your exterior wall and roof assembly. If the room is heated by electricity at cost of 1.7 ¢/KWh. Find the daily energy cost for maintaining the room temperature. Show all your work and calculation in proper format. Mention all your assumptions used to solve above problem. Use illustration and written explanation to clarify your approach.
