对宾夕法尼亚州费城的热水、空间供暖和空间冷却系统进行了分析，分析了有无太阳能辅助以及有无非峰值蓄热；佛罗里达州代托纳海滩；这些地点覆盖不同的气候，并由具有不同发电和增长模式的电力设施提供服务。确定公用事业公司的服务成本和业主的资本投资成本，以获得年度总成本。通过比较，可以得出新系统在何时何地比传统系统更经济的结论，以及非峰值热存储如何影响这些结果。引文:ASHRAE Transactions，1983年，第89卷，pt。新泽西州大西洋城1B号

Water heating, space heating, and space cooling systems with and without solar assistance and with and without off-peak thermal storage are analyzed for Philadelphia, PA; Daytona Beach, FL; and San Diego, CA. These locations cover different climates and are served by electric utilities having different generation and growth patterns. The utility's costs of service and the homeowner's capital investment costs are determined in order to obtain total annual costs. Comparisons permit conclusions as to where and when the novel systems will be economical compared to conventional systems, and how off-peak thermal storage affects these results.
