Realization of Building Energy Saving and Solar Heating in Cold Areas based on Computer Technology

Abstract

The climate of cold area is cold in winter (the average temperature of the coldest month is 0 ∼ - 10 °C and < - 10 °C), the outer envelope of the building bears the interference of low temperature, wind and snow, hot in summer, and the outer envelope of the building bears the interference of high temperature, solar radiation and rain. Therefore, the design of buildings should meet the requirements of winter heat preservation, cold prevention and antifreeze. At present, 95% of the new buildings built every year in China are still high energy consumption buildings. The heating energy consumption per unit building area is about three times of that in countries with similar climate. The building energy consumption in China accounts for nearly 30% of the national energy consumption. With the development of building technology, the improvement of people’s awareness of energy and the attention of government departments, China should vigorously develop building energy saving, which is urgent. The demand of solar energy is increasing day by day, and the situation of energy utilization is tense. However, the large-scale use of conventional energy will have a negative impact on the environment. As a kind of renewable energy, solar energy is inexhaustible and will not increase the environmental load. It will become an important part of the future energy structure. In the building energy consumption, the energy consumption of domestic hot water and heating accounts for a considerable proportion. Using solar energy to meet the requirements of low-grade energy consumption, such as domestic hot water and heating, has great energy-saving benefits. Therefore, solar energy heating technology has been paid more and more attention. At the same time, with the development and maturity of computer technology, it also provides more support for solar heating technology. This paper analyzes the realization of building energy saving and solar heating in cold areas by using computer technology.
