Development of an ASHRAE 152-2004 Duct Model for the Single-Family Residential House

This paper presents the results of the development of the duct model based on ASHRAE standard 152-2004 (ASHRAE, 2004) using the DOE-2.1e building energy simulation program. To accomplish this, FUNCTION commands for DOE-2 were used to develop the duct model and provide the improved predictions of the duct heat loss or gain from the unconditioned space as well as supply or return duct leakage. After applying the duct model to the DOE-2 base-case simulation model, simulation results were compared with the measurement from the case-study house for verification
