What is the construction energy efficiency rate of 50%?
The comprehensive building energy conservation is a system engineering, must be led by the state legislature, the government, to make a comprehensive and clear policy of building energy saving, and by the relevant government departments in accordance with the country's energy policy, make comprehensive building energy efficiency standards; to be truly comprehensive building energy-saving, the design and construction of each link, at all levels of supervision and management departments, developers, operation and management departments and users, in strict accordance with the provisions of the national energy policy and energy conservation standards, full implementation of various energy-saving measures, so that every citizen really establish the overall concept of building energy efficiency, building energy efficiency will be truly implemented
Comprehensive building energy efficiency is the sum total of energy saving in each link of the whole life process of building. Refers to the construction in site selection, planning, design, construction and use of the process, through building materials, products and equipment with energy-saving, energy-efficient construction standards in the implementation of energy-saving equipment, operation and management of building use, reasonable design of building envelope, heating, cooling and lighting, improve ventilation, to run the efficiency of drainage and pipe system, and the use of renewable energy, while ensuring the function and quality of the indoor thermal environment of the building, reduce the energy consumption of buildings, rational and effective use of energy
In the new building energy specifically refers to the planning, design, building (renovation and expansion), transformation and use of the process, implementation of energy-saving standards, using energy-saving technology, technology, equipment, materials and products, improve the efficiency of heat preservation and insulation performance and heating, air conditioning and heating systems, with the operation and management system building strengthen the use of renewable energy, under the premise of ensuring the quality of the indoor thermal environment under the increase of indoor energy exchange resistance, in order to reduce the energy consumption of heating system, air conditioning refrigeration and heating, lighting, hot water supply due to a large number of heat generated.

Building energy efficiency means to reduce energy consumption as much as possible in the construction and construction of building materials and in the construction and use of buildings, to meet the needs of the same or achieve the same purpose. Building energy-saving, in developed countries in order to reduce the loss of energy in the original building, commonly known as "improving the energy utilization of the building, in order to increase the construction of comfortable conditions, the rational use of energy, improve energy utilization efficiency.
