A green building Public buildings The future development direction of architecture, The Cisco Smart City project, located in Panyu District, Guangzhou, is a three-star public building with green buildings. The project uses a number of leading green building design technologies. It is mainly reflected in the building energy saving schemes such as setting sponge city facilities to absorb runoff and rainwater within the site, using large temperature difference cooling to save energy consumption for transmission, and setting solar photovoltaic systems on roofs and facades to make full use of renewable energy. In addition, the proportion of recyclable materials and recyclable materials of the project reaches 10.81%.
In terms of comfort, the lobby and coffee shop with constant air volume all air air-conditioning system and the tower office with variable air volume all air air-conditioning system have improved the air filtering efficiency.

In fact, in order to further develop green buildings and continue to promote healthy development, the country has issued a series of standards such as the Technical Guidelines for Passive Ultra Low Energy Consumption Green Buildings, the Evaluation Standard for Green Buildings (GB/T 50378-2019), and the Technical Standard for Near Zero Energy Consumption Buildings (GB/T 51350-2019).
At present, the real estate market has slowed down and entered the "silver era". Consumers' demand for health quality and lifestyle is forcing the real estate products to return to "quality".
The growth mode of real estate enterprises is also changing from focusing on speed and scale to focusing on benefits, and the initiative to explore the improvement of environmental protection benefits and green development is enhanced. For example, Vanke pushed the green building industry chain, Evergrande set up a green building research base, and Landsea actively promoted the green building transformation of existing projects.
As a developer of Cisco Smart City, Country Garden has always been following the national pace, creating a better life for owners by creating a healthy living environment, vigorously following up the research on green building standards, constantly improving the group's own green building standard system, and comprehensively implementing the concept of sustainable development, To contribute to the sustainable development of green ecology in China's human settlements.
Green buildings are considered as the future development direction of buildings in line with the green production mode. The 13th Five Year Plan for Building Energy Efficiency and Green Building Development issued by the Ministry of Housing and Urban Rural Development clearly states that by 2020, the proportion of green building area in new urban buildings will exceed 50%.
Accordingly, a series of standards such as the Evaluation Standard for Green Buildings 2019, the Technical Standard for Buildings with Near Zero Energy Consumption, the Evaluation Standard for Healthy Buildings, and the Evaluation Standard for Healthy Houses have been successively issued, and the requirements for residential products are developing towards "lower carbon, more comfortable, and healthier".
Under the guidance of planning and standards, many real estate enterprises have already run on the runway of green buildings. The 2019 Top 50 Report on Green Credit Index of China's Real Estate Enterprises jointly prepared by China Standards Ranking Research Institute, China Investment Association and China Securities Market Design and Research Center shows that 53 listed real estate enterprises have a total area of 70 million square meters of green building certification, and Vanke, Country Garden and China Evergrande rank among the top three in the area of green building certification.
In addition to building guidelines on environmental issues such as energy conservation, water conservation, pollution prevention, waste classification, environmental greening, biodiversity protection, etc., in 2019, Country Garden Design System Sustainable Development Research Institute also carried out the "Country Garden Healthy and Comfortable Residential (Passive Ultra Low Energy Consumption and Assembled) Building Technology Guidelines", "Country Garden Green Building Design Guidelines" The preparation of a series of guidelines such as the Technical Research on the Implementation of Country Garden Sponge City Project and the Design Guidelines for Country Garden Sponge City.
In terms of green building certification, during the 2019 annual report period, Country Garden built 117 green building certification projects, with a total floor area of 49.2 million square meters. In 2019, Country Garden also built one German PHI passive housing certification project and three American LEED certification projects. At the same time, in terms of low impact development, Country Garden will design and construct 110 sponge city projects in 2019, covering an area of 18.64 million square meters.
Do you know what accounts for a large proportion of urban garbage? It is construction waste. Up to now, the national stock has reached more than 20 billion tons, which has become one of the important factors restricting urban waste treatment.
This year's government work report proposed to improve the effectiveness of ecological environment governance and strengthen the construction of sewage and garbage disposal facilities. For this reason, Country Garden has taken a variety of green environmental protection measures for its construction projects to ensure legal compliance, strive to greatly reduce the impact on the environment during the construction process, and achieve effective management of the construction site environment of the development project.
Among them, the construction waste generated in the construction process will be classified and placed on the site first, and then handed over to professional organizations for recycling and compliance treatment; During construction, measures such as site hardening, greening, watering and dedusting shall be taken to reduce dust pollution.
In addition, recyclable materials such as steel bars and copper are selected in the architectural design of Country Garden Development Project, and prefabricated components account for a large proportion. The construction process uses premixed concrete and commercial mortar to reduce the environmental pollution and material waste caused by on-site construction. Some projects make full use of the integrated design of building civil decoration, and use the kitchen and bathroom with integrated qualitative design.
It is reported that prefabricated buildings assembled by prefabricated parts and components on the site can reduce 80% of on-site construction waste and 60% of material loss, and significantly reduce construction noise and dust.
Country Garden has been constantly upgrading "green technology" in the research and development of green buildings. In 2019, the environmental assessment coverage of Country Garden and its construction projects reached 100%, and no major negative impact on the environment and natural resources occurred. At the same time, it continues to promote green construction, green operation and green office initiatives, takes active and effective measures to deal with climate change and protect biodiversity, and guards our common green home.
In the coming year, there will be a large number of green building projects and sponge city construction projects in Country Garden for acceptance. They will conduct field surveys on the landing of buildings and the actual operation effect of buildings to ensure the construction of truly sustainable buildings.
In the next three to five years, Country Garden will continue to actively participate in the application of national, provincial and ministerial research projects, continue to take advantage of the advantages of the real industry platform, and deepen cooperation with scientific research institutes and universities to achieve the combination of production, teaching and research, and help the implementation of R&D technology.
