本文利用两栋住宅的5分钟间隔天气能源数据，研究了天气变化对能源利用的影响：住宅1为具有先进效率特征的传统住宅，住宅2为具有相对先进效率特征的净零太阳能住宅。我们的研究结果表明，2号住宅的能源消耗对天气变量的变化不像传统住宅那么敏感。平均而言，我们发现，每增加一个单位的加热和冷却度分钟，房屋1和房屋2的能源使用量分别增加约9%和5%和5%。此外，我们的研究结果表明，非温度变量，如太阳辐射和湿度影响能源使用，房屋2的敏感性始终低于房屋1。此外，我们的研究结果表明，能源使用对天气的敏感性取决于季节和白天/夜晚的特定时间。(C) 2015 Elsevier Ltd.版权所有。
This paper studies the impact of weather variation on energy use by using 5-minutes interval weather-energy data obtained from two residential houses: house 1 is a conventional house with advanced efficiency features and house 2 is a net-zero solar house with relatively more advanced efficiency features. Our result suggests that energy consumption in house 2 is not as sensitive to changes in weather variables as the conventional house. On average, we find that a one unit increase in heating and cooling degree minutes increases energy use by about 9% and 5% respectively for house 1 and 5% and 4% respectively for house 2. In addition, our findings suggest that non-temperature variables such as solar radiation and humidity affect energy use where the sensitivity rates for house 2 are consistently lower than that of house 1. Furthermore our result suggests that the sensitivity of energy use to weather depends on the season and specific time of the day/night. (C) 2015 Elsevier Ltd. All rights reserved.
