加热、通风和空调（HVAC）控制用于有效地减少家庭能量管理系统（HEMS）中的能量消耗。对于HVAC控制，由于HVAC操作与室内环境条件显著相关，因此有必要评估室内舒适度。虽然有一些室内舒适度的指标，个人有不同的舒适范围。问卷调查是收集个人舒适范围数据的一种方法。但是，它需要用户的贡献。因此，我们提出了一种新的调查方法，改变了向用户提出问题的间隔，以减少所需的响应数量。此外，提出了一种不需要问卷调查的舒适度估计方法。该方法分析用户对HVAC系统的操作，例如触摸其开/关开关。在日本宫城县的一个实验室和16个住宅中安装了一台能够利用这两种方法的HEMS。使用该HEMS进行了一项实验，它能够将维持每个人舒适度所需的反馈次数平均减少32.2%。HEMS提供了与每小时问卷相同的准确性。也就是说，它确认了基于空调运行的估计与基于每小时问卷的估计几乎相同。
Heating, ventilation, and air conditioning (HVAC) control is used to effectively reduce energy consumption in a home energy management system (HEMS). For the HVAC control, it is necessary to evaluate the indoor comfort level because the HVAC operation is significantly related to indoor environmental conditions. Although there are some indices for indoor comfort, individuals have different comfort ranges. A questionnaire is one way to gather data on individual comfort ranges. However, it requires contributions from users. Therefore, we proposed a new survey method that varied the intervals of the questions addressed to users to reduce the number of responses needed. Additionally, a comfort estimation method was proposed that did not require a questionnaire. This method analyzes the user's operation of the HVAC system, such as touching its on/off switch. An HEMS with the capability of utilizing these two methods was installed in a laboratory and 16 houses in Miyagi prefecture, Japan. An experiment using this HEMS was conducted, and it was able to reduce the number of feedbacks needed to maintain each person's comfort by an average of 32.2%. The HEMS provided the same accuracy as hourly questionnaires. Namely, it confirmed that the estimation based on the air conditioner operations was almost the same as that based on an hourly questionnaire.
