1绪论上世纪70年代中期以来,一种基于市场的、全新的节能新机制——合同能源管理(简称EPC,Energy Performance Contracting,国内简称EMC,Energy Management Corporation)在市场经济国家中逐步发展起来,而基于这种节能新机制运作的专业化的“节能服务公司”(在国外称ESCo,在国内简称EMCo)也得到了迅猛发展。合同能源管理机制是通过节能服务公司和用能单位签订节能合同,提供能源审计、节能改造方案设计、施工设计、原材料和设备采购、施工、节能量监测和效益保 1 Introduction Since the mid-1970s, a new energy-saving mechanism based on the market-EPC (Energy Performance Contracting, abbreviated as Energy Management Corporation) has gradually developed in market economy countries. The specialization of “ESCOs” based on this new energy saving mechanism (ESCo in other countries and EMCo in China) has also been rapidly developed. Contract energy management mechanism through the energy-saving service companies and energy companies signed energy-saving contracts, to provide energy audits, energy-saving program design, construction design, procurement of raw materials and equipment, construction, energy saving monitoring and benefit insurance
