Case Study of Two Passive Solar Commercial Buildings: Volume 1, Johnson Controls, Inc. at Salt Lake City, Utah and Comparison with Building at Wells, Minnesota: Final Report

摘要

In this study, ''calibrated'' simulation models were developed for two small commercial buildings with energy conserving features including passive solar elements and daylighting. BLAST version 3.0 was used with the input files adjusted so that good agreement was obtained between predictions and actual measurements from on-site monitoring and data recording. The calibrated models were evolved by first obtaining a good match between predicted and measured temperature profiles and then examining the thermal loads to confirm performance. A limited number of parametric runs were made using a range of typical climate conditions to determine how the buildings might be expected to perform in other locations and to gain insight into this technique for evaluation. During this process, comparison was made with a baseline building configured to represent more conventional construction practices. It was found that both buildings performed well when compared to the baseline building, particularly during the heating season. It is concluded that the calibrated model technique is a very useful method for evaluation of a building design which might be replicated in several locations, and that it should be useful in comparing different design features. Volume 1 is primarily concerned with the Johnson Controls Building at Salt Lake City, Utah. It also includes presentation of climate sensitivity data from both the Johnson Controls Building and the Security State Bank Building at Wells, Minnesota. (ERA citation 12:040722)
