Question:
Consider a contemporary single-family detached house located in suburban Milwaukee, Wisconsin. The home is a single-story structure with an attached unheated garage that is insulated in the same fashion as the house living space. The house is located on a 0.75 acre lot (which is large compared to most suburban densities) and has several small trees and shrubs near the house. The house is designed to have an air change rate of 0.5 ACH under typical weather conditions, is maintained at 70}F year-round, and has the following characteristics:
