上海公共建筑能耗现状及节能潜力分析 总被引:52,自引:10,他引:52
根据上海地区办公楼、商办楼、宾馆和商厦能耗调研的数据,对上海公共建筑空调能耗的现状作了评价。认为上海建筑用能水平较低,用能不尽合理,提出用系统能量效率比用单位面积平均一次能耗量作为建筑节能的评价指标更为合理。 相似文献

对山东某地区商务办公建筑进行了调研。应用抽样调查的方法,对该地区37个样本量的能耗进行统计处理,得出了该地区单位面积建筑能耗为72.14 k W·h/(m~2·a),单位面积供暖能耗为14.74 kgce/(m~2·a)。研究结果表明,山东某地区的商务办公建筑在用能方面还存在一些问题,建筑节能潜力较大。这对于科学确定商务办公建筑的能耗指标,进而实施用能超定额加价政策具有一定的参考价值。 相似文献

A review on buildings energy consumption information 总被引:4,自引:0,他引:4
The rapidly growing world energy use has already raised concerns over supply difficulties, exhaustion of energy resources and heavy environmental impacts (ozone layer depletion, global warming, climate change, etc.). The global contribution from buildings towards energy consumption, both residential and commercial, has steadily increased reaching figures between 20% and 40% in developed countries, and has exceeded the other major sectors: industrial and transportation. Growth in population, increasing demand for building services and comfort levels, together with the rise in time spent inside buildings, assure the upward trend in energy demand will continue in the future. For this reason, energy efficiency in buildings is today a prime objective for energy policy at regional, national and international levels. Among building services, the growth in HVAC systems energy use is particularly significant (50% of building consumption and 20% of total consumption in the USA). This paper analyses available information concerning energy consumption in buildings, and particularly related to HVAC systems. Many questions arise: Is the necessary information available? Which are the main building types? What end uses should be considered in the breakdown? Comparisons between different countries are presented specially for commercial buildings. The case of offices is analysed in deeper detail. 相似文献

《Journal of Building Performance Simulation》2013,6(5):313-328
There are many factors that drive the energy consumption and demand in high-rise commercial office buildings. Understanding the effects of individual building parameters and two-factor interactions can be very useful for directing building audits and developing energy simulation models. A fractional factorial analysis was conducted to evaluate a large number of building parameters in an effort to quantify their effect on building energy consumption and demand. The analysis utilized building data collected from 22 building audits of high-rise commercial office buildings located in the downtown Chicago Loop area. Simulation results for three of the buildings show the effects of each factor and two-factor interactions on energy consumption and demand over a set of climate zones. The factors of primary importance include lighting and equipment power density, chiller efficiency, window U-value, the mass of interior furnishings and supply fan static pressure. 相似文献
