通过对重庆市城市发展新区村镇住宅建筑能耗的全年调研,得到了重庆城市发展新区村镇居民的用能习惯及村镇建筑的能耗水平。采用分类归纳法,对家用电器测试归纳,并对非用电设施调研估算归纳。基于实测数据和调研估算数据建立了重庆城市发展新区村镇住宅建筑用能模型,并进行验证。结果表明,重庆城市发展新区村镇住宅能源消费形式以电为主,为电+燃气+薪柴+煤+太阳能的混合型结构;村镇居民用能习惯在使用何种能源的选择上存在差异,但对同一种能源的使用差异性不大。实测数据表明,所建立的村镇住宅建筑用能模型能准确反映重庆城市发展新区新村镇住宅建筑用能的实际情况。 相似文献

Energy usage and energy efficiency are of increasing concern in Mexico, electricity generation principally depends upon fossil fuels. On one hand, the stocks of these fuels have been confirmed to be critically limited. On the other hand, in process of electricity generation by means of these fuels, a number of poisonous by-products adversely affect the conservation of natural eco-system.This paper focuses on estimation of energy consumption, energy savings, reduction of emissions of CO2 for use of urban and rural household appliances in Mexico between 1996 and 2021.The analysis concentrates on six major energy end uses in the residential sector: refrigerators, air conditioners, washing machines, TV set, iron and heater.It is estimated that by 2021 there will be a cumulative saving of 22,605 GWh, as a result of the implementation of government programs on energy efficiency that represents a cumulative reduction of CO2 emissions of 15,087 Tg CO2.It means that Mexico can reduce in 5650 MW the generation capacity of national electricity system, which is to avoid burning 40.35 MM barrels of oil.The findings can be useful to policy makers as well as household appliances users. 相似文献

Polyvinylchloride (PVC) panel is one of the most favorite decorative materials that has been popularly applied as finishing
of ceiling in residential buildings. It is about five years that the people incline to redecorate the ceiling of old buildings
with PVC panel in big cities of Iran, such as Mashad. In this study, the influence of ceiling PVC panel on the cooling and
heating loads of studied apartment were determined by software DeST-h. In addition, the summer natural ventilation of the
mentioned apartment is investigated by determining the wind speed into the apartment through the computational fluid dynamics
(CFD) software. The evaluation of environment indoor wind velocity showed that most of the apartment space is a comfortable
zone. The results of studied building analyses demonstrated that using PVC panel on the ceiling can decline the energy consumption
of the penthouse (fifth level) of the investigated building, which is about 3.7% and 7% for studied methods of without and
with air layer, respectively. In addition, although the existence of air layer can decline the cooling and heating loads,
the increase in air layer thickness did not show significant decrease on building energy consumption. However, the PVC panel
is expensive and is not suitable to be used for ceiling thermal insulation, but adding a thin layer of air between ceiling
and PVC panel can be a good step toward sustainable building, when the people are inclined to utilize it as a decorative ceiling. 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

As the Korean economy and society continues to develop, the number of subways are expected to increase. This increase will demand greater heating and cooling energy as well as convey a sharp rise in the overall energy consumption. This study aims to develop energy conservation and analysis for subways. This study shows the information, that is, tables, graphs, and charts concerning the trend in energy efficiency in subways between 1999 and 2001. We suggest a practical application for energy conservation methods and efficient energy use based on the investigations and analyses. 相似文献
