Question

Alex Wren of Owens Corning Fiberglass talks to Terry Jones, a homebuilder, to find out how much fiberglass insulation he intends to use in building homes during the next year. Albert then multiplies that number by the total number of builders in the territory. He is using a ___________ approach to measure sales potential.

a) multivariable
b) use of product
c) breakdown
d) regression
e) buildup

Answer 1

Adding 8 cm of fiberglass insulation increases the attic's R factor, leading to reduced heat loss and lower heating costs. The specific percentage drop cannot be calculated without additional information on the initial R values and heat loss rate.

Step-by-step explanation:

To determine the percentage drop in heating costs from adding insulation, one must understand the concept of the R factor, which is a measure of thermal resistance. The R factor indicates how well the insulation can prevent heat transfer. Adding an extra 8 cm of fiberglass insulation would increase the R factor of the attic, which in turn would reduce the rate of heat loss through it, leading to lower heating costs. Without the specific R values and an initial rate of heat loss, it's impossible to calculate an exact percentage reduction in heating costs. Generally, an increase in insulation thickness will result in reduced energy loss, thus lowering heating bills.
