Standard Hourly Meteorological Data In Building Energy Simulation Of The Applied Research

With China's urban construction and the development of the built environment for the continuous improvement requirements, building energy consumption has continued to increase. Buildings energy efficiency reduced energy consumption of buildings by satisfies the basis of environmental requirements. Building sustainable development has become an important issue. To this end, countries have formulated relevant policies and regulations to ensure that the energy-saving work carried out. The 《hot summer and cold winter residential building energy-saving design standards》 (JGJ134 — 2001) and 《Summer heat in winter residential building energy-saving design standards》 (JGJ75 — 2003) have Already promulgated, which showed that the construction thermal environment and building environmental control system dynamic simulation of the importance and necessity , which makes the process of building thermal simulation in HVAC engineering design and related to the importance of research. The process for building thermal simulation requires a month, a quarter of the year and even daily, hourly meteorological parameters, therefore, access to a set of realistic reflection of meteorological and environmental characteristics of data is the process of building thermal simulation of a basic work.The present research mainly include:1. In this paper we analysis the standard of hourly data. On behalf of my choice of five climatic zones of typical cities of Beijing, Shanghai, Guangzhou, Harbin and Kunming, using energy simulation DOE-2 program for the same typical office building. Use the 30 cities measured data to simulate building energy consumption and use that for a basic. Now China has two sets of standards of the database (China typical weather CNTMY and the Chinese standards CSWD). Then I found that the two sets of data to simulate the whole building energy consumption is relatively close to the 30 energy consumption on average. The difference in energy consumption between -15% to 10%. It closed to the China's actual basic climate change.2. According to the simulation of the cities in 30 monthly energy consumption values, use the mathematical statistical theory to analyze the relationship between the dry bulb temperature, dew point temperature , solar radiation, relative humidity , wind speed and building energy consumption. the results show that the temperature and moisture is the main impact of building energy consumption factors. It is different from region to region. The meteorological parameters on the impact of energy consumption are different. Mainly in heating energy consumption areas, dry bulb temperature is a major factor in energy consumption and in air-conditioning areas, air moisture affect is a major factor in energy consumption.3. Due to different regions the meteorological parameters on some extent have different impact of energy consumption. So we selected typical month of different regions may use different weighting factor. This article uses mathematical statistics to calculate for each of meteorological parameters standardized coefficient on energy consumption. Then obtain the meteorological parameters weighting factor for Beijing, Shanghai , Guangzhou, Harbin and Kunming. That likes a reference to the people that research for the meteorological parameter.
