摘　　要：针对常规建筑供能系统存在的不足,充分利用城市既有天然气一次能源供应管网优势,以提高总能系统效率为出发点,本文提出了基于天然气基分布式能源系统智能建筑能源物联网(NDES-SG),并提出了NDES-SG集成基本原则与关键科学问题。为诠释NDES-SG的集成、节能潜力以及系统评价方法,给出了一个范例系统,系统计算结果表明,与常规供能系统相比,NDES-SG实现节能达22.2%。NDES-SG概念为进一步提高能源利用效率与实现新一代的建筑能源供应系统提供了思路。For the deficiency of conventional building energy supply system, in order to make full use of advantage of existing city primary energy supply pipeline network in natural gas and improve the efficiency of the total energy system, the building energy smart grid based on natural gas based distributed energy system is proposed in this paper. The basic principles of system integration and key scientific issues of NDES-SG system are also given in this paper. To interpret integration, energy saving potential and system evaluation method of NDES-SG, a simplified case is presented. The results show that NDES-SG system saves 22.2% compared with conventional energy supply system. NDES-SG concept provides a guideline for improving further energy efficiency and implementing a new building energy supply system.
