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: General Occupants Pets (large dog) Bedrooms (typical furniture and decorations) Living Room (typical furniture and decorations) Dining Room Bathrooms Kitchen (typical appliances) Laundry Room (typical appliances) Basement footprint Gross floor area (including garage) Living gross floor area Perimeter (including garage) Wall heights Gross wall area Overhang Window area (evenly distributed on 4 sides of house) Door area (3 doors) Garage door area Roof area (including garage) Wood siding, bevel, 0.5" x 8" tapered Plywood sheathing, 0.5" Framing, nominal 2 x 4, 16-in center, with fiberglass batt insulation Gypsum, 0.5" Wood shingles, cedar shake Felt building paper Plywood sheathing, 0.5" Framing, nominal 2 x 6 trusses, 24" centers 23° roof pitch 4 1 3 1 1 2 1 1 2500 ft2 3000 ft 2500 ft 360 ft 8 ft 2800 ft None 300 ft 60 ft? 120 ft 3500 ft?

Heating and cooling loads due to infiltration under the design Winter and Summer conditions. b. Overall UA values for each element of the building envelope (i.e., wall, roof, window, door, etc.). c. Heating load contribution due to sensible heat transmission d. Total heating load. e. Cooling loads due to the sunlit exterior surfaces. f. Cooling load due to the windows. g. Cooling loads due to the unconditioned spaces. h. Cooling loads due to the interior heat gains. i. Total cooling load. j. Select, describe, and determine the total costs for the installation of commercially available heating and cooling systems for this house.
