    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
