Problems solved by technology

However, it can be seen from the previous analysis that the thermal performance evaluation method of ordinary energy-saving buildings is relatively simple and rough in dealing with solar radiation problems, and is not suitable for the evaluation of solar buildings. It is very important to study methods suitable for the evaluation of energy-saving performance of solar buildings. necessary and urgent

Abstract

The invention discloses an energy-saving performance estimating method of a driven solar heating building. The method comprises the following steps of: acquiring basic building information, basic meteorology and energy saving calculation parameters by using a conventional method; calculating the characteristic parameter SG of the driven solar heating building according to the basic information; acquiring a SG-SES relation curve by using conventional methods, such as the dynamic energy consumption simulation of building, searching the driven solar heating energy-saving index SEG of the building by an SG value according to an SG-SES curve relation map; and calculating and acquiring an auxiliary heat consumption index Eaux of the driven solar building. In the invention, the shortcoming of the solar heating building in a performance estimation aspect, which is caused by the consideration neglect of solar radiation in a current building energy-saving design standard, is overcome, and the energy-saving performance of buildings adopting a plurality of heat-collecting modes is evaluated so that an estimation result is more scientific and reasonable.

Description

technical field [0001] The invention relates to the field of building energy conservation, in particular to an energy-saving performance evaluation method for passive solar heating buildings. Background technique [0002] 1. Introduction to passive solar heating [0003] Building a conservation-oriented society, vigorously developing regional "energy-saving and land-saving residences" to alleviate the energy shortage trend, and to adjust the harmonious relationship between people, buildings, natural environment and resources has become the basic national policy of our country. According to the statistics of the Ministry of Construction, under the current economic level, the energy consumption of urban residential buildings has exceeded 25% of the total energy consumption in the country. my country has a huge population and limited land and resources. No matter how small the consumption is multiplied by 1.3 billion people, it is a huge amount, and no matter how large the pro...
