Application of an ASHRAE 152-2004 Duct Model for Simulating Code-Compliant 2000/2001 IECC Residences

This paper presents the results of the application of the duct model based on ASHRAE 152-2004 - Method of Test for Determining the Design and Seasonal Efficiencies of Residential Thermal Distribution Systems (ASHRAE 2004) to the code compliant 2001 International Energy Conservation Code (IECC)1 (ICC 1999, 2001) using DOE-2.1e building energy simulation program2. Code compliant DOE-2 simulation model was developed based on IECC and the duct model (Kim and Haberl 20083) was applied to the IECC-code compliant model. Then, the efficiency analyses of the IECC-compliant simulation model were performed on: 1) duct properties, and 2) the different locations of HVAC system and ductwork including the attic space and conditioned space based on the different climate zones
