Question:
A wood frame wall consists of 2x6 wood studs (38mm x 140mm)spaced at 16? o.c. (on centre), with fibreglass batt insulation(see ?insulating blankets and batts in Tbl. 8.1) between the studs.Each stud is 7?9? long and sits between a 2x6 bottom plate and a2x6 top plate such that each wall ends up being 8? tall (standardheight of a sheet of drywall). The wall is sheathed with 7/16?thick ?hardboard, medium density? (Tbl. 8.1) on the outside, and?9.5mm gypsum or plaster board? (Tbl. 8.1) on the inside. The househas four such walls each measuring 16 feet long by 8 feet tall, andis located in Toronto (heating degree days below 18 = 3653). Thehouse is heated with electricity at a cost of $0.10/KW.h. Don?tforget the air films, and use the winter outside air filmcoefficient. You may also ignore any extra framing details of thecorners. Just find the repeating unit as shown in class and assumeit continues around all four walls.Calculate the area-weighted average RSI-value of the whole wallassembly, area weighting the stud-batt-top/bottom plate layer andthen using the tabular method including the inside and outsidesheathing layers as well as the air films.
