目的：本研究考察了英国客厅温度与英国建筑存量模型中标准假设相对应的程度。方法：对英格兰248个家庭在92个冬季每45分钟测量一次的现场温度进行分析，并与假设的加热期内外21摄氏度的恒温器设置进行比较。结果：在假设的供暖期间，家庭平均显示出较低的内部温度，并且加热到21摄氏度的持续时间比普通模型假设的要短得多，大约20%的家庭从未达到假设的21摄氏度的需求温度。数据显示，在工作日和周末，温度处于或高于需求温度的持续时间仅相差约45分钟，与假设的7小时的差异相反。家庭之间的差异很大。结论：这些发现表明，目前使用的供暖需求和供暖时间的标准假设并不能准确反映英国住宅的客厅温度。实践含义：标准假设可能必须修改，特别是关于工作日和周末的区分。在使用标准假设时，对给定家庭内部温度的预测可能存在较大误差。(C) 2013年作者。Elsevier B.V.版权所有。
Objective: This study examines the extent that temperatures in English living rooms correspond to standard assumptions made in established UK building stock models.Methods: Spot temperature measurements taken every 45 min over 92 winter days in 248 homes in England were analyzed and compared to the assumed thermostat setting of 21 degrees C inside and outside the assumed heating periods.Results: Homes on average displayed lower internal temperatures during assumed heating periods and significantly shorter durations of heating to 21 degrees C than common models assume, with about 20% of homes never reaching the assumed demand temperature of 21 degrees C. Data showed a difference of only about 45 min in the duration of temperatures at or above the demand temperature for weekdays and weekends, contrary to the assumed difference of 7 h. Variability between homes was large.Conclusion: These findings suggest that currently used standard assumptions of heating demand and heating duration do not accurately reflect the living room temperatures of dwellings in England.Practice implications: Standard assumptions might have to be revised, in particular regarding the weekday-weekend differentiation. The prediction of internal temperature for a given home contains potential large error when using standard assumptions. (C) 2013 The Authors. Published by Elsevier B.V. All rights reserved.
