Abstract:Considering that the energy-saving technology of building electricity has its relativity and limitations and no effective and convenient method of evaluation on this technology is available,the energy- saving technology shall be measured and evaluated in terms of overall economic efficiency and carbon emission;the self-examination shall be performed for the electrical energy-saving technology and the characteristics and applicability of commonly-used energy-saving technologies shall be analyzed,including intelligent lighting control system,frequency control,electricity sub-metering and utilization of renewable energy,etc.;the common application errors shall be pointed out and the suggestions in the actual application shall be proposed.
Key words:building electricity;energy-saving technology;investment payback period;embodied carbon;lighting energy saving;electricity sub-metering;frequency control;renewable energy
摘 要:建筑电气节能技术有相对性、局限性,也缺少有效、方便的评价方法,应从综合经济效益、碳排放两个方面对节能技术进行测评;对电气节能技术进行反思,分析智能照明控制系统、变频调速、用电分项计量、可再生能源利用等常用节能技术的特点、适用性;指出常见的应用误区并提出实际应用中的建议。
关键词:建筑电气;节能技术;投资回收期;隐含碳;照明节能;用电分项计量;变频调速;可再生能源
