北京地区大型商场空调系统一般为典型的夏季制冷、冬季供热设计,而由于室内照明及商品照明负荷大、持续时间长,商场人员相对密集、人体的全热负荷大等因素,商场实际大部分营业区冬季温度普遍偏高,冬季非但不需供热,反而有时要制冷, 相似文献

This paper presents the results of a study that estimated the DSM energy saving and load management potential in commercial and government/institutional sectors in Oman (central grid area) and evaluated its impact on generation capacity and energy savings. The end-use (lighting and air-conditioning) energy consumption data have been collected in two major segments of the commercial sector for simplicity and to save time and money. Another unique aspect of the study is the inclusion of the energy savings, in transmission and distribution (T&D) losses that are estimated by using generation expansion planning approach. The study has found that DSM is financially beneficial from customers’ point of view as the discounted payback period of investment in efficient lighting and air-conditioning is between 4 and 12 years of the surveyed sample. From the utility point of view the capacity saving at the horizon year is between 372 and 596 MW and the overall energy saving for the whole planning horizon is about 29–44 TWh. The total avoided cost in generation and capacity saving is somewhere between 416 and 597 million dollars. 相似文献

夏热冬暖地区办公建筑能耗模拟与分析 总被引:2,自引:2,他引:0
夏热冬暖地区是我国经济和建筑产业最发达的地区之一,也是建筑能耗最多的地区之一。分析和研究夏热冬暖地区建筑能耗的特点对建筑节能有重要的意义。本文用eQUEST建筑能耗模拟软件模拟了夏热冬暖气候下不同的建筑围护结构的能耗性能,并与实际调查结果进行了比较。结论表明:办公类建筑中的空调是最大的能耗终端,全年的能耗以办公设备和照明的能耗最稳定。有外保温措施和同时具有内、外保温措施最大区别在于节省空调电力消耗31.3%和39.1%。说明建筑外墙保温系统是建筑节能的重要手段。 相似文献

The government of Thailand legislated an Energy Conservation Promotion Act (ECP Act) in 1992 and set bye-laws that identify designated buildings (DBs) and detail mandatory requirements for energy conservation for DBs in 1995. An Energy Conservation Promotion Fund (ENCON Fund) was also created to fund energy audits on 1900 DBs. Recently the requirements and procedures for energy conservation in buildings have been revised where system performance requirements for building envelope, lighting, air-conditioning, and hot water generation are adopted. Moreover, the new building energy code (BEC) distinguishes different categories of DBs, provides credit for use of solar energy, and introduces a new option of whole building energy compliance. The authors develop building models from data obtained from energy audit reports and use them to estimate savings on energy and peak demand from future new buildings using forecasted energy and peak demand data from the Load Forecast Subcommittee, a panel tasked to forecast future electric load of Thailand. From a modest level of energy saving in the first year that the code is expected to be enforced, the level of saving rise to over 10% and 20% annually of requirement of target buildings in 6 and 12 years respectively. 相似文献

The building energy performance improvement of large-scale public buildings is very important to release China’s energy shortage pressure. The aim of the study is to find out the building energy saving potentials of large-scale public and commercial buildings by energy audit. In this paper, the energy consumption, energy performance, and audit were carried out for a typical commercial mall, the so-called largest mall in Asia, located in a hot-summer and warm-winter climate zone. The total annual energy consumption reaches 210.01 kWh/m2, of which lighting energy consumption accounts for 30.03 kWh/m2 and the lift and elevator energy consumption accounts for 40.46 kWh/m2. It is by far higher than that of the average building energy consumption in the same category. However, the annual heating, ventilation, and air-conditioning (HVAC) energy consumption is only 87.19 kWh/m2 even though they run 24/7. It proves that the energy performance of the HVAC system is good. Therefore, the building energy savings potential mainly relies on reducing the excessive usage of lighting, lifts, and elevators. 相似文献
