智能建筑环境控制系统的照明与空调节能效果实证研究

Empirical Study on the Energy Efficiency of Lighting and Air Conditioning in Intelligent Building Environmental Control Systems

近年来有许多关于建筑智能控制系统节能减排的研究,但聚焦其实际应用的节能效果相关实证研究十分有限。本研究以深圳某办公楼14层实际智能化改造案例为研究对象,采用“A-B-A”的实证研究方法开展了为期92 d的实证实验。在实际场地安装基于物联网和边缘计算的智能建筑环境控制系统后,设置对照组对其有效性进行科学验证:分别选取2022年7月—9月设置“A-B-A”3组实验条件进行对比,通过对人员存在、照明灯具和空调系统的运行时间数据进行收集和分析。实证研究结果表明,照明与空调分别可节能约25.98%和19.50%,具有可观的节能潜力和绿色效益。本研究可为国内外智能建筑节能提供有效、科学的实证样本。

In recent years,there have been many studies on the energy-saving and emission reduction of building intelligent control systems,but empirical study focusing on their practical applications is limited.This study took the actual intelligent renovation case of a 14th-floor office building in Shenzhen as the research object,and conducted a 92-day empirical experiment using the"A-B-A"empirical research method.After installing the intelligent building environment control system based on the Internet of Things and edge computing onsite,a control group was set to scientifically verify its effectiveness.Three groups of experimental conditions of"A-B-A"set in July and September 2022 were selected for comparison,and the operating time data of personnel presence,lighting fixtures and air conditioning systems were collected and analyzed.The results indicate that lighting and air conditioning can save about 25.98%and 19.50%of energy,respectively,with significant energy-saving potential and green benefits.This study can provide effective and scientific empirical samples for the energy-saving of intelligent buildings both domestically and internationally.
