Why is the slogan of Beijing Urban Construction Longyue Eco-City called "25℃ Constant Temperature Community"?

First of all, Yuelai successfully became one of the first 16 "sponge city" pilot projects in the country in 2015. As the core area of ??Liangjiang New District in Chongqing, it has carried out sponge city construction with the purpose of protecting the Yangtze River, investing more than 4 billion Yuan, including 75 projects including public and private residential areas, urban water systems, municipal roads, garden green spaces, etc., aiming to create an ecological city with green waters and clear mountains;

The second Yuelai Gaoyikou section is Chongqing The only section that utilizes renewable energy, water source heat pumps, centralized energy supply and other ecosystems;

Utilization of renewable resources: The use of water source heat pumps, the so-called "water air conditioner", is environmentally friendly and energy-saving, and reduces emissions, allowing In summer it is cool both indoors and outdoors. Water source heat pump, centralized cooling and heating: Adopt the district energy system setting and connect it to the entrance of each household. After the residents install it by themselves, they can adjust the room (household) temperature, control device and household hot and cold metering (hot and cold apportionment by household). device or facility. The centralized cooling and heating system saves 12% more energy than central air conditioning, reduces outdoor cooling equipment, and reduces the heat island effect by 2-3 degrees;

The project also has high-tech features such as green roofs, grass ditches, and sunken green spaces. Technology, the roof system grows plants through the roof waterproof layer, which plays a role in thermal insulation. It can reduce indoor air-conditioning energy consumption by 20% in summer and save 10% of heating energy consumption in winter.

In addition, the project is surrounded by rivers on three sides, and each household is equipped with a fresh air system - a mechanical ventilation system is installed in the house, which can remove haze and continuously provide fresh air indoors 24/7, 365 days a year, to satisfy human health. need.
