A Simplified Residential Base-Case Model

Abstract

This study was for the DOE-2.1e program to develop a simplified residential ASHP house model in Houston, Texas. The house characteristics were based on the standard reference design and requirements as defined in Chapter 4 of the 2009 IECC. To develop the 2009 IECC compliant DOE-2.1e residential house model, this study used the step-by-step procedure started from the RUN 3A which is one of the example for a simple structure in the samp1e.inp file included in the DOE-2.1e program package. The RUN 3A is an office building model, which has 30 degrees of azimuth, 5,000 ft2 of the floor area with 8 feet of the floor-to-ceiling height and 2 feet of the plenum height. Through the step-by-step procedure, the RUN 3A was modified to become a residential model (i.e., RUN 30 in this study), which has a single-story, a single-family, a south-facing and detached house, which has 2,500 ft2 of the floor area with 8 feet of the floor-to-ceiling height without the plenum. In addition, the residential base-case model replaced with an ASHP system from a VAV system for RUN 3A.
