What is the heating temperature stipulated by the state?

According to Indoor Air Quality Standard (GB/T 18883-2002). It is stipulated that the heating standard in winter is 16 ~ 24℃, and the indoor temperature that meets this standard is indoor comfortable temperature.

The Design Standard for Energy Efficiency of Residential Buildings in Hot Summer and Cold Winter Areas stipulates that the design temperature of bedrooms and living rooms in indoor heating environment in winter is 16 ~ 18℃. According to the indoor environmental quality standard item in the "Guidelines for Planning and Design of Well-off Urban and Rural Residential Science and Technology Industry Demonstration Community in 2002" formulated by the state, the indoor temperature in heating areas in winter is 16 ~ 2 1℃.

Extended data:

When the temperature is lower than 12℃, 80% people who sit feel cold, and more than 20% people who are active feel cold. Hygiene regards 12℃ as the lower limit of building thermal environment. Generally speaking, the most suitable environmental temperature for human body is 18℃ to 22℃, which varies from person to person.

The most suitable indoor temperature should be kept at room temperature 65438 08℃ and relative humidity should be kept at 30-40%. When the room temperature is 23℃, the relative humidity should be kept at 40-50%. In a family with a baby, under normal circumstances, the indoor temperature should be around 20℃ and the humidity should be kept at 50% ~ 60%. It can be adjusted according to the characteristics of children who are afraid of cold and heat.

Because of various factors such as environment, buildings and terminals, when the room temperature exceeds 18℃, the energy consumption will increase by 20% for every degree of increase. ?

When the heating temperature exceeds 22℃, the indoor air will be extremely dry, which will affect the body's own body temperature regulation function, leading to increased body temperature, vasodilation, accelerated heart rate, endocrine disorders and so on. At the same time, excessive temperature will also increase the volatile emission of toxic and harmful gases in furniture, floors, stones and other decorative materials. Compared with low temperature, too high temperature is more harmful to the body.
