采用能源审计的方法,分析了武汉市政府办公楼和大型公共建筑的节能潜力、节能率与回收期。结果表明,能源行为管理,过渡季节的自然通风,提高用能系统的能效比,充分利用可再生能源和自然采光等是成熟、可靠的节能技术。提出了节能分析按等价热值或者能质系数计算;节能率、经济性以年为单位核算;以实测能耗评价节能建筑,避免采用多种节能技术的建筑实际上是非节能建筑的现象。
Using the method of energy audit, this paper analyzes the energy saving potential, energy saving rate and payback period of Wuhan municipal government buildings and large-scale public buildings. The results show that energy behavior management, natural ventilation during the transitional season, improving the energy efficiency of the energy-using system, making full use of renewable energy and natural lighting are mature and reliable energy-saving technologies. Proposed energy-saving analysis according to the equivalent calorific value or quality factor calculation; energy-saving rate, economy in years as a unit of accounting; measured energy consumption evaluation of energy-efficient buildings to avoid the use of a variety of energy-saving technologies is actually building non-energy-saving building phenomenon.
