The following wood frame house is located in Saskatoon, Saskatchewan (Degree days = 6053), and is heated with electricity at a cost of $0.10 per kilo Watt-hour (KWH). The house measures 6m wide by 12m long and 8m tall, and the walls are constructed as follows, (from inside to out): 9.5 mm gypsum board Polyethylene vapour barrier, plastic film . 5.5 of Glass fiber batt Insulation (fits in a 2x6 wood stud cavity) Look under "insulating blankets and batts" in table 8.1 9.5mm wood plywood 3" of extruded smooth skin polystyrene insulation, 35kg/m3 density Wood siding, bevel, 13 x 200 mm Outside temperature for January is -15C Inside temperature is 21C 1. (3 marks) Draw a vertical sketch of the assembly, roughly to scalo 2. (10 marks) Calculate the total thermal resistance (RS1-total) of the wall assembly as described using the tabular chart method shown in class 3. (6 marks) Using the tabular chart method shown in class (you may continue on the chart you drew for part 2 of this question), calculate the temperatures at the material layer interfaces for the wall, and plot them on a vertical section of the wall assembly with a temperature profile line, roughly to scale. 4. (4 marks) Calculate the January (31 days) heating cost for the wall portion of the house (all 4 walls) using the Indoor and outdoor tempeatures given. 5. (4 marks) Calculate the annual heating cost for the wall portion of the house (all 4 walls) using the degree days given. 6. (6 marks) If the same house sits on a foundation measuring 6m wide and 12m long (as given), with foundation walls extending down 1790mm below grade, and insulated with 2" of extruded polystyrene insulation (35kg/m3) extending all the way down the wall, using the below grade heat loss chart, calculate the annual heating cost for the basement portion of the house.
