Evaluation of Building Design/Analysis Software for Microcomputers

摘要

This report documents the results of an evaluation of microcomputer-based programs for building energy analysis and heating, ventilating, and air-conditioning system designs. The programs were evaluated for ease of use and calculation performance. The study showed that all programs evaluated were suitable for use by building designers and that no program package could be identified as clearly the best. Each program has a unique set of strengths and weaknesses. Load-estimating and duct-sizing software packages were tested by simple design problems. Load-estimating software performed consistently, although differences in algorithms resulted in clear discrepancies among cooling load predictions. Duct design programs did not agree particularly well, especially with respect to pressure drop calculations. Further performance evaluations are necessary. Information in this report should help designers select the program packages appropriate for their experience level and design application.
