In 2018, the project was selected as the energy saving subsidy project of Beijing Commission of Housing and Urban-rural Development, realizing the overall building energy saving of 15%-20%. It would receive 30 CNY/㎡ as subsidy, totally more than 6 million CNY from government for energy saving.
In 2019, Nord Property entrusted Sanzen Energy to carry out energy-saving transformation for the newly completed phase III project of 300,000 square meters and phase I project of 100,000 square meters.
The project adopts ground source heat pump system for heat- ing and cooling
Construction area 65,000 square meters, including 39,000 square meters for the Old town
In 2017, Sanzen Energy was authorized to implement this rectification project.
