Exam 32: Heat Load Calculations

A corner office measures 10 feet by 12 feet 6 inches with an 10-foot ceiling. The two outside walls are brick with 3 1/2 inches of insulation. There are no windows in the walls. The ceiling has 9 1/2 inches of insulation beneath a vented roof. The floor is a slab floor sitting on the ground. What is the heat load for the walls for a design temperature difference of 75°F?

A corner office measures 10 feet by 12 feet 6 inches with an 10-foot ceiling. The two outside walls are brick with 3 1/2 inches of insulation. The ceiling has 9 1/2 inches of insulation beneath a vented roof. The floor is a slab floor sitting on the ground. It is desired to put a 4-foot by 3-foot double pane window in each of the two outside walls of the office. What is the heat load for this office by adding the two windows for a design temperature difference of 75°F?

A side of a house measures 10 feet by 15 feet. There is one window which measures 3 feet by 4 feet. The wall is a wood frame with siding and 3 1/2 inch insulation + 1 inch polystyrene sheathing (R-16). The window is single pane plus storm window. Find the heat load for the window for a 70° F design temperature difference.

The wall is a wood frame with siding and 3 1/2 inch insulation + 1 inch polystyrene sheathing (R-16). The window is single pane plus storm window. Find the heat load for the wall (excluding the window) for a 70° F design temperature difference.

The wall is a wood frame with siding and 3 1/2 inch insulation + 1 inch polystyrene sheathing (R-16). The window is single pane plus storm window. Find the heat load for the entire side of the house for a 70° F design temperature difference.

The U factor is the amount of heat transferred through 1 sq yard of structure for each degree temperature difference between the inside and outside surfaces.

The units for the heat transfer multiplier are British thermal units per hour per square foot or Btu/h sq ft.
