 Energy-conserving measures in the electric design of the building
 Abstract：This text has design the angle from the building electrically and explain the energy-conserving importance, has put forward several kinds of effectual and feasible energy-conserving measures in engineering design .
 Keyword：Energy-conservation  The power losing  Power factor Electricity-saving lamp
 China is a big consumer of energy, the relative shortage of energy, but the waste of energy has been a corresponding serious. As a secondary energy contradiction between supply and demand of power has become increasingly prominent in recent years, the lack of energy has seriously restricted the growth of the national economy. Energy-saving issue has been China's national economic development of a long-term strategic approach, Energy conservation then became every electrical designers must seriously consider the issue. Now, the construction of the electrical design of several energy-saving measures to share some observations.

 建筑电气设计中的节能措施
 ［摘要］本文从建筑电气设计角度阐述了节能的重要性，提出了几种在工程设计中行之有效又切实可行的节能措施。

 我国是个能源消费大国，能源相对短缺，然而能源浪费却相应严重。作为二次能源的电能供需矛盾近年来越来越突出，能源的缺乏已严重制约着国民经济的发展。节能问题一直是我国发展国民经济的一项长远战略方针，那么节约电能就成为每位电气设计人员必须认真考虑的问题。下面就建筑电气设计中的几种节能措施谈谈一些看法。
 １供配电系统的节能设计
 根据负荷容量，供电距离及分布，用电设备特点等因素合理设计供配电系统，做到系统尽量简单可靠，操作方便。变配电所应尽量靠近负荷中心，以缩短配电半经减少线路损耗。合理选择变压器的容量和台数，以适应由于季节性造成的负荷变化时能够灵活投切变压器，实现经济运行减少由于轻载运行造成的不必要电能损耗。
