数值模拟气象资料在建筑能耗计算中的应用 总被引:2,自引:0,他引:2
在应用DOE-2计算不同地区的建筑能耗过程中,如何获得该地区的典型气象年的资料一直是最关键的问题。介绍了一种使用计算机数值模拟仿真的方法,即使用Meteonorm软件来求得任意地区的气象资料,再将其输入到D0E-2中来计算建筑能耗;以及将这种方法应用于湖北省地区的住宅节能标准的研究的情况。 相似文献

The present paper deals with the energy performance, energy classification and rating and the global environmental quality of school buildings. A new energy classification technique based on intelligent clustering methodologies is proposed. Energy rating of school buildings provides specific information on their energy consumption and efficiency relative to the other buildings of similar nature and permits a better planning of interventions to improve its energy performance. The overall work reported in the present paper, is carried out in three phases. During the first phase energy consumption data have been collected through energy surveys performed in 320 schools in Greece. In the second phase an innovative energy rating scheme based on fuzzy clustering techniques has been developed, while in the third phase, 10 schools have been selected and detailed measurements of their energy efficiency and performance as well as of the global environmental quality have been performed using a specific experimental protocol. The proposed energy rating method has been applied while the main environmental and energy problems have been identified. The potential for energy and environmental improvements has been assessed. 相似文献

Numerous studies have focused on improving energy efficiency in commercial buildings. Engineers and researchers have developed complex methods to improve energy efficiency, but buildings are often managed by non-specialised technicians who need understandable and cost-effective actions to implement in their buildings. This paper presents basic actions on which to base improvements in energy efficiency in commercial buildings in operation. Furthermore, obtained results and details of the implementation of these techniques in various buildings in the Universitat Politècnica de València are presented. 相似文献

The performance of different HVAC systems varies when coupled with different buildings. This paper examines the relationship between building heating and cooling load and subsequent energy consumption with different HVAC systems. Two common HVAC systems in use throughout the UK office building stock, variable air volume (VAV) system and fan coil (FC) with dedicated outside air system, have been coupled with a typical narrow plan office building with and without daylight control and for both cellular and open plan.The results presented in this paper clearly indicate that it is not possible to form a reliable judgment about building energy performance based only on building heating and cooling loads. For the two investigated systems, variable air volume system and fan coil with dedicated outside air system, the difference between system demand and building demand varied from over −40% to almost +30% for cooling and between −20% and +15% for heating. If a heat recovery unit is used, the difference in heating performance is even greater, rising to −70%. 相似文献

Schools are the most suitable type of building for the application of energy efficiency and good indoor air quality measures. This is justified by the fact that such measures can promote sustainability to the future citizens, and even more, ensure a comfortable and healthy environment for educational purposes. Unfortunately, in practice school buildings face the same, or even more intense, energy performance and indoor air quality problems as any other building. The purpose of this study is to investigate the energy efficiency, thermal environment and indoor air quality in public nursery and elementary school buildings in the city of Kozani, located at the cold climatic zone of Greece. The survey, conducted both by in-field measurements and by questionnaires, reveals the main parameters affecting the overall performance of the investigated buildings. The problematic building envelope, the improper control of heating and lighting systems, the absence of proper legislative measures and, above all, the lack of interest concerning the efficiency of such buildings are the main factors in the reported efficiency. 相似文献

The article presents the implementation of management measures that have reduced the gas consumption for space heating of a university building in Spain by 40%. The measures affect the use of the building, e.g., the use of its spaces, and the scheduling of its occupancy. They also affect the management of the heating system: a protocol for turning the system on and shutting it off has been developed.The work is part of a framework for action by the Technical University of Catalonia covering more areas and for a longer period of time, in which policies have been designed for managing buildings and a number of studies have been developed on the energy consumption of the university's buildings. The article highlights the work methodology proposed to achieve the energy savings calculated theoretically in a previous study. The implementation of these measures in the case, from November 2006 until May 2007, has reduced consumption from 113.2 kWh/m2 to 68.7 kWh/m2 a year; thus, the hypothesis has been validated. In addition, it was possible to examine methodological details more closely. Finally, the relationship between the people involved in the process (the building owners, managers and energy users) is a determining factor. 相似文献

低碳建筑是指在建筑生命周期内,从规划、设计、施工、运营、拆除、回收利用等各个阶段,通过减少碳源和增加碳汇实现建筑生命周期碳排放性能优化的建筑。笔者以重庆市《低碳建筑评价标准》为例,对低碳建筑评价指标体系进行简要介绍;并与重庆市《绿色建筑评价标准》对比,找出低碳建筑与绿色建筑评价指标体系的异同点。通过对比分析发现,绿色建筑评价指标体系侧重于建筑资源、能源消耗的基本情况以及营造的环境水平,而低碳建筑评价标准侧重于建筑资源能源消耗的详细情况及碳排放性能。 相似文献

Energy efficiency or buildings should be regard as a kind of idea but not merely a technological means through out the whole process of architectural design. Architects should fully understand and mater the concrete means of energy efficiency of buildings so as to create the architectural forms accord with the ecological law. namely "green form" This articie will present the abovementioned idea by introducing the design of Administrative Building in New School Area of Ningbo Univesity of Technology 相似文献
