In recent years, HEMS (home energy management systems) have received attention as energy conservation measures, and are being adopted increasingly in smart houses. The Home Environment Visualization and Management System was developed by the author’s laboratory. The purposes of this system are to raise residents’ interest in the indoor thermal environment, encourage the use of passive control methods, and promote awareness of health, safety, and energy-saving in the home. In our proposed system, a dedicated website for each home, an LED indicator that shows indoor and outdoor temperature by color level, a real-time advice display function, and a weekly environmental report were prepared. In the weekly report, a comparison graph of power consumption with other homes was shown. In this study, a verification of the effects of this system, intended for about twenty subject homes, was conducted. The main results of the system operation are as follows:

1) The number of times the website was viewed increased during the summer and winter, though the browsing logs differed greatly among residences. This demonstrates that it is important to provide easy-to-use information to promote browsing.

2) In the log indicating reactions to the real-time advice, a positive reaction of at least 80% was confirmed. This indicates that providing advice in real time is effective in encouraging environmental adjustment behaviors.

3) From the answers to a questionnaire about the weekly environmental report, an energy-saving effect was obtained as power consumption increased. This shows that offering comparisons with other homeowners is effective in encouraging energy conservation.

From these results, it was confirmed that the website, the LED indicator, and the real-time advice were useful for promoting environmental adjustment behavior. In addition, it was confirmed that the weekly environmental report was useful for promoting energy-saving behavior.

近年来，HEMS（家庭能源管理系统）作为节能措施受到关注，越来越多地应用于智能家居。家庭环境可视化与管理系统由作者实验室开发。该系统的目的是提高居民对室内热环境的兴趣，鼓励使用被动控制方法，并提高家庭健康、安全和节能意识。在我们提议的系统中，准备了每个家庭的专用网站、按颜色级别显示室内和室外温度的 LED 指示灯、实时建议显示功能和每周环境报告。在周报中，显示了与其他家庭的用电量对比图。在这项研究中，验证了该系统的效果，旨在为大约二十个主题之家进行。系统运行的主要结果如下：

1）夏季和冬季网站的浏览次数有所增加，但不同住宅的浏览日志差异很大。这表明提供易于使用的信息以促进浏览非常重要。

2) 在显示对实时建议的反应的日志中，确认了至少 80% 的积极反应。这表明实时提供建议对于鼓励环境调整行为是有效的。

3) 从每周环境报告问卷的回答中，随着电力消耗的增加，获得了节能效果。这表明与其他房主进行比较在鼓励节能方面是有效的。

从这些结果可以确认网站、LED指示灯和实时建议对于促进环境调整行为是有用的。此外，确认每周环境报告对促进节能行为是有用的。
