What are the energy-saving materials?

(l) Building envelope energy-saving building envelope includes windows, walls, roofs, etc. to improve the thermal performance of the building envelope, so that the heat energy supplied to the building can be effectively utilized inside the building, so as not to be lost quickly through its envelope, so as to achieve the purpose of reducing energy consumption. Realize the energy saving of enclosure structure and improve the sealing performance of doors, windows and walls, so as to reduce heat transfer loss and air infiltration and consume heat energy.

(2) Heating system energy saving heating system includes three parts: heat source, heating network and indoor heating facilities. It is necessary to improve the boiler operation efficiency and pipe network transmission efficiency without excessive loss of heat energy in the process of conversion and transmission. Therefore, it is necessary to improve the equipment performance of the heating system, improve the design, construction and installation level, and improve the operation management technology. In the part of indoor heating facilities, technical measures such as double pipe entry, household measurement and room temperature control should be adopted, and the heating measurement and charging system should be implemented, so that residents are both energy consumers and energy savers, mobilize people's enthusiasm for active energy conservation, and fully realize the due benefits of building energy conservation.

(3) Developing and using renewable energy is the direction of building energy consumption. Renewable energy is clean energy, which refers to the inexhaustible and inexhaustible resources that can be continuously regenerated, continuously utilized in nature. It is harmless or extremely harmful to the environment, and the resources are widely distributed, which is suitable for local development and utilization. Renewable energy mainly includes solar energy, wind energy, water biomass energy, geothermal energy and ocean energy. Wind energy. Wind energy refers to the energy loaded by the wind. The size of wind energy depends on the wind speed and air density. solar energy. Solar energy refers to the energy loaded by the sun. Its measurement is generally based on the total amount of radiation from sunlight to the ground, including the sum of direct radiation from the sun and scattered radiation from the sky.
