The total project heated area is 1.8 million m2, of which the first phase was 220,000 m2. The first phase has been operational since 2015, and it has maintained a winter indoor temperature that is over 20°C, which is higher than the national standard.  After the total project is completed, about 13,500 tons of coal will be saved annually and annual emissions of 37,800 tons of CO2, 410 tons of SO2, 760 tons of NOX, and 2600 tons of dust/particles will have been eliminated, all compared to traditional coal heating.
