The space-conditioning calculation section of the Home Energy Saver utilizes the detailed hourly building energy simulation program DOE-2.1E (Birdsall et al. 1990). User inputs for the energy-related characteristics of houses are collected and interpreted outside of DOE-2 (Pinckard et al. 2003). The prepared data are then passed to a master DOE-2 Building Description Language (BDL) file (Winkelmann et al. 1993a) through macro input variables (Winkelmann et al. 1993b). These and other macro variables internal to the DOE-2 BDL file are used to calculate input quantities, convert input quantities to the correct formats, and select the correct lines of conditional DOE-2 code for each house simulation. DOE-2 output files are scanned and the relevant output quantities are captured, converted and compiled, and returned for display (Pinckard et al.2003).

The following sections describe inputs to the DOE-2 model, the details of the model, and outputs from the DOE-2 model.
