Notice on Approving the "Civil Building Energy Saving Design Standard (Heating Residential Building Part)" (Trial) as a Ministry Standard
(86) Chengshezi No. 95
In order to implement the State Council's "Provisional Regulations on Energy Conservation Management" and meet the needs of energy-saving design work for urban and rural construction projects, the "Civil Building Energy Saving Design Standard (Heating Residential Building Part)" (Trial) compiled by the China Academy of Building Research and relevant units has been reviewed and approved by our Ministry as a Ministry Standard, with the number JGJ26-86, and will be implemented on a trial basis from August 1, 1986. Localities may compile corresponding implementation details based on the requirements of this standard and in combination with the technical and economic conditions of their regions, and submit them to the Design Bureau of the Ministry of Urban and Rural Construction and Environmental Protection for filing. If you have any questions or comments during the trial implementation, please inform the Institute of Building Physics of China Academy of Building Research.

Preparation Instructions
This standard is compiled by China Academy of Building Research in accordance with the requirements of the Notice No. 114 of the Ministry of Urban and Rural Construction and Environmental Protection (83) Chengshejianzi. It is compiled by the Institute of Building Physics and the Institute of Air Conditioning of China Academy of Building Research, together with the Institute of Building Economics of China Building Technology Development Center, the Department of Atmospheric Sciences of Nanjing University, the Department of Heating of Harbin Institute of Civil Engineering, the Institute of Building Materials Science of Liaoning Province, and the Institute of Beijing Institute of Architectural Design.
This standard consists of 6 chapters and 8 appendices, including general provisions, heating period degree days and indoor calculated temperature, building heat consumption index and heating energy consumption estimation, building thermal design, heating design, and economic evaluation.
This standard is based on the needs of my country's socialist modernization construction and the existing technical and economic level. It emphasizes that under the conditions of ensuring the use function and building quality and complying with the economic principle, the heating energy consumption should be controlled at the specified level by adopting appropriate technical measures that conform to national conditions in the building design and heating design. For this purpose, the insulation requirements of the enclosure structure in this standard are further improved than those of the "Civil Building Thermal Design Code", and regulations are also made for the design of heating and heating systems and pipe insulation.
This standard is formulated on the basis of investigation and research and absorbing domestic and foreign tests. It is the first civil building energy-saving design standard compiled in my country, but it is currently limited to the heating residential building part. The other parts of the heating civil building need to be supplemented in the future. In the process of using this standard, if you find that some of the provisions are inappropriate, please send your opinions directly to the Building Physics Research Engineering 2 Design Standard Full Text Information System

Chapter 1 General Provisions
Article 1.0.1 In order to implement the energy conservation policy promulgated by the state. To reverse the situation of high heating energy consumption and poor thermal environment quality of residential buildings in severe cold and cold areas in my country, this standard is specially formulated by adopting appropriate technical measures in building design and heating design, while ensuring the use function and building quality and complying with economic principles, and controlling the heating energy consumption at the prescribed level. Article 1.0.2 The energy consumption involved in this standard mainly refers to heating energy consumption. Energy consumption in other aspects should be implemented in accordance with relevant standards, specifications or regulations. Article 1.0.3 This standard is mainly applicable to the energy-saving design of heating systems for newly built and expanded residential buildings and residential areas with centralized heating. Reconstructed residential buildings, other civil buildings with similar functions to residential buildings, auxiliary buildings of industrial enterprises, etc. can be used as a reference. This standard does not apply to temporary buildings and underground buildings.
Article 1.0.4
When designing building energy conservation in accordance with this standard, it shall also comply with the requirements of relevant design standards, specifications or regulations. Engineering 6 Construction Standard Full-text Information System

Chapter 2 Heating Period Degree Days and
Indoor Calculated Temperature
Article 2.0.1 This standard specifies the control indicators of heat consumption of residential buildings in different regions and the limit values ​​of the average heat transfer coefficient of the enclosure structure according to the heating period degree days. Article 2.0.2 The heating period degree days and distribution map of major cities and towns across the country are shown in Appendix 1, Table 1.1 and Attached Figure 1.1.
Article 2.0.3 The indoor design temperature of the living rooms (including bedrooms, living rooms, etc.) of general residential buildings is 18℃; the average indoor calculated temperature of all rooms, including auxiliary rooms, used to estimate heating energy consumption is 16℃.
