Energy problem is one of the important issues, like the Chinese economy in recent years the rapid development of the environmental problems have caused the country attaches great importance to, energy conservation and emissions reduction is the top priority. Countries around the world are actively developing new energy and renewable energy. The "green energy" in the construction industry get more and more importance. In the process of research of new green energy saving energy, solar energy and shallow geothermal energy and other new energy increasingly widely used in construction industry, its irreplaceable important position.Solar inexhaustible, unlimited, and can be used for permanent sources of energy, rich resources, free from contamination. To surface of shallow geothermal resources are called, refers to the surface of the soil, groundwater, rivers, lakes and other absorb solar energy, geothermal energy and reserves of low temperature heat.Solar energy and shallow geothermal energy is widespread. But the mere use of solar energy and shallow geothermal energy have their own limitations. Solar energy is strongly influenced by season, climate, geographical position, the heat source is not stable. And surface soil, shallow geothermal energy is greatly influenced by the water, equipment investment, etc.At present, in engineering practice, the most common solar system or use a single ground source heat pump hot water supply system to solve building internal cooling in summer, winter heating.The main content of the subject is the research and application of ground source heat pump, solar energy systems. Discusses the working principle of the system, the initial investment and running late, maintenance of comprehensive economic analysis comparison, discusses the system of science and economy. To solve specific engineering practice, which can realize solar integration design, meet the needs of users24-hour supply of hot water, and can compensate for the variations of soil temperature field around a single ground source heat pump system, such as defects. Use of ground source heat pump and solar energy complementary advantages of energy saving, increase the reliability of the system. In the specific engineering practice, more rational, scientific, reasonable use of green energy. The subject’s central argument is practical use of the design engineering cases. Specific research methods through observation and track the running equipment, joint more solar energy-ground source heat pump systems in initial investment and operation cost, and engineering system design stage, in the operation of the equipment in need of improvement, discusses and analyzes the problems of joint solar energy-ground source heat pump system applied to provide theory and practical experience. To make green energy gets more and more widely used in construction field, really want to users, which achieve the goal of energy saving, and can meet the practical needs. Building For the general engineering design personnel to provide new ideas, new methods, optimize the design, improve design level.
