GREEN AND LOW-CARBON
At Longfor Gaobeidian Railway City, under the concept of landscape paintings, we conducted the application of an ecological rainwater system through the development of filtration, retention, storage, purification, and utilization to integrate the concept oဣf sponge city into the whole community as a way to realize the sustainable circulation of rainwater and add ecological materials and clean energy for use.
Our design team integrated the concept of sponge city into the whole community as a way to realize the sustaina🃏ble circulation of r🍸ainwater and make use of rainwater to create a rainwater garden. We adopted organic materials for the pavement of the ground in a scientific way to speed rainwater penetration with the advantage of energy-saving and consumption reduction. An ecological grass ditch was designed in the middle of the site to collect, transport, and discharge rainwater, having a certain effect on rainwater purification.
In addition, Longfor Group creatively conducted the readable design of ecological display and education by installing a realtime interaction screen for introducing the sponge city system, temperature, humidity, and PM2.5 data of the whole community, greatly elevate🦂d the interactive experience of the community.

Longfor Group follows the “passive priority, active optimization” principle in design and creates ultra-low energy consumption building projects in Jiangqiao Town, Jiading District, Shanghai. To achieve the indoor environment and energy consumption targets, we adopt multiple passive measures, including prioritizing external shading, energy-saving doors and windows, and thermal insulation of the enclosure structure to reduce the demand for building heating and air conditioning. At the same time, we improve the energy efficiency of heating, air conditioning, and fresh air systems and utilize renewable energy, such as solar energy, to achieve a far lower level of buildingไ energy consumption than conventional buildings. According to statistics, after this design, the energy consumption levels of heating, air conditioning, lighting, domestic hot water, and elevators should be꧟ reduced by more than 50% compared to the 2016 building energy-saving design standards.

At the start of 2023, xnbl88.commercial finalized the pilot retrofit of high-efficiency cooling stations at the Nanjing Longwan Paradise Walk project. Following the renovation, each core equipment in the cooling station system at Nanjing Longwan Paradise Walk was equipped with automatic machine operation adjustments, frequency control, and optimization search features, increasing the system’s automation level. This ensured water and air balance throughout the air-conditioner system, leading to improved efficiency and energy savings. According to data, as of the end of the reporting period, the high-efficiency cooling station retrofit at Nanjing Longwan Paradise Walk saved a total of 500,000 kilowatt-hours of electricity with a energy efficie𓃲ncy rate of 17.4% and reduced carbon dioxide emissions by 250 tons.
As the iconic landmark of Longhu Group's urban renewal, the Longhu Blue Engine Industrial Park, where the Longfor smart headquarters are located, was formerly known as the Auto Parts Mall and officially opened in May 2021.
In the෴ past two years of renovation design and implementation, Longhu has fully respected the building conditions and did not ♛generate additional structural usage, reducing approximately 42632 tons of carbon emissions.
The project adopﷺts prefabricated construction technology and green prefabricated building materꦗials produced by Longhu Ecology, with an assembly rate of nearly 75%, which increases efficiency by 50% compared to traditional construction methods. At the same time, the latest smart building and IoT system settings are adopted to integrate and control building energy consumption, continuously optimize energy use, and create a green model with a low-carbon concept.
The Lathe Plant in Hefei was designed and built by Soviet experts in the 1950s and 1960s. It symbolizes and epitomizes Hefei’s industrial culture and has crucial historical protection value. Following𒈔 the requirements of the local government and respecting the industrial heritage, we used artistic methods to give it a new lꦡife.
We follow the Historical Building Protection Law and strive to inject new vitality into the old city with limited intervention and activation. Longfor Group uses a combination of six repair methods and red brick materials to maximize the characteristics of the factory during the production period. Inside the building, we fully respect the original spatial features of the industrial heritage, preserve and restore the 😼valuable arched dome, and create a rich indoor space with a new metal roof and skylight system. In addition to safeguarding industrial memory, we fully consider the regional characteristics and integration with the surrounding environment. We have transformed the Cheqiao Factory site into a block garden model, creating a leisure place that promotes regional cultural quality, diversity, and inclusiveness.
Longfor has taken multiple measures to steadily promote soil remediation, improve air quality, and reduce water pollution to address issues surrounding old industrial bases and environmental impacts. After the transformation, the ecological environment has significantly improved. Through this industrial heritage transformation, we have given an old industrial base new functions and spiritual out🀅looks through selective heritage inheritance, modern architectural techniques, and active intervention.
