4 EML 4600 LECTURE 5 Heating Load Calculations Trane Trace Calculation Options: UATD: The conduction heat loss is calculated with the equation: Heat Loss = U-Value × Area × (Winter Design Temperature - Room Heating Design Temperature.) At the user's option, internal loads may be scheduled on, although it is not recommended for design calculations. The room load effect is assumed to be instantaneous for both internal and external values of heat gain. No credit is allowed for solar heat gain. CEC-DOE2: This room load method duplicates the “Precalculated Weighting Factors” in the DOE2.1c energy analysis program, and is based on the original ASHRAE weighting factors for light, medium, and heavy construction.

Solar Utilization When do we need heating for a building? When the building is residential in nature. When the building is light commercial with significant exposed walls and windows and low internal heat gains. When we are at the perimeter of a building.
