Extended data:

Building energy efficiency, originally in developed countries, is to reduce the energy loss in buildings, which is generally called "improving the energy utilization rate in buildings". Under the condition of ensuring the improvement of building comfort, we should make rational use of energy and continuously improve the energy utilization rate.

Building energy efficiency refers to the implementation of energy-saving standards, the use of energy-saving technologies, processes, equipment, materials and products in the planning, design, new construction (reconstruction and expansion), transformation and use of buildings, the improvement of thermal insulation performance and the efficiency of heating, air conditioning, refrigeration and heating systems, and the strengthening of the operation and management of building energy-using systems.

Using renewable energy, on the premise of ensuring the indoor thermal environment quality, increase the indoor and outdoor energy exchange thermal resistance, thus reducing the energy consumption of heating system, air conditioning refrigeration and heating, lighting and hot water supply due to large heat consumption.

Building energy conservation is a systematic project. In the process of comprehensive promotion, relevant supporting policies and regulations should be formulated and the implementation should be strengthened. There should be supporting standards, including technical standards, product standards and management standards, so as to facilitate supervision and inspection in the implementation process.

For new technologies, new processes, new equipment, new materials and new products, we should give policy support and increase market promotion. In short, to do a good job in building energy conservation, as long as the relevant departments and governments at all levels work together and cooperate closely, China's energy-saving goal can be achieved.
