Taking the 280-plus enterprises affiliated with the Electrical and Mechanical Industry Bureau of Shenyang as an example, the building has a building area of ​​about 5 or 6 million square meters, and the amount of coal used for heating is tens of thousands of tons per year. Especially in these enterprises, more than 200 collective enterprises and newly-acquired original districts belong to small-scale production plants, production support and welfare.
