According to the definition of "green and energy-saving building" by the Ministry of Construction, green and energy-saving buildings provide people with healthy, comfortable and safe living, working and activity spaces, and at the same time use resources efficiently in the whole life cycle of the building to limit the impact on the environment. things".
Green buildings follow the principle of adapting measures to local conditions, and comprehensively consider the climate characteristics, geographical environment, natural resources and other factors of various parts of our country, and adopt appropriate external wall thermal insulation system, sunshade system, external window thermal insulation system, natural ventilation system, natural lighting, solar energy and other factors. Various technologies such as integration with buildings, ground source heat pump air conditioning, reclaimed water reuse, green building materials and intelligent control have been screened, optimized and integrated to form a building energy-saving technology system with regional characteristics, with reasonable site selection and planning, resources Utilize the characteristics of high-efficiency circulation, comprehensive and effective energy-saving measures, healthy and comfortable building environment, harmless waste reduction, and flexible and suitable building functions.
1. Energy-saving technology of building envelope
This technology refers to improving the thermal performance of the building envelope, isolating outdoor heat from entering the room in summer, preventing indoor heat from leaking outside in winter, and maintaining indoor comfort as much as possible, so as to reduce the utilization rate of heating and cooling equipment and reduce energy load. , to achieve energy saving. The complete set of technologies are: high-efficiency external wall thermal insulation technology; external window energy-saving technology, which adopts hollow low-emission glass windows; Surface combined roof insulation system.
2. Energy utilization technology
This technology refers to converting solar energy and geothermal energy into heat energy and electric energy through conversion devices, which can effectively solve the problems related to hot water, heating, air conditioning and lighting in buildings. The complete set of technologies are: solar photovoltaic power generation technology; solar heat concentration technology; solar energy and building integration technology; temperature, to meet people's use of hot water in life and production.
3. Environment and environmental protection technology
This technology refers to improving people's living environment, reducing environmental load, and protecting the environment as much as possible during the construction and use of buildings. The main technologies are: three-dimensional greening technology for buildings; green building materials technology, which refers to the use of environmentally friendly building materials that can be reduced, reused and renewable in the process of construction and use; comprehensive water-saving technology, including the use of water-saving appliances. , rainwater and sewage collection and reuse technology, ground water conservation technology; simulate the wind environment and sunshine law around the building, and carry out efficient natural ventilation and natural lighting design.
In the future, buildings will greatly reduce energy consumption through various advanced energy-saving technologies and means, and finally achieve the goal of zero-energy buildings.
