Promoting green buildings is an important measure to carry out the source reduction of construction waste, and it is also a key task requirement for Zhongshan City to promote the construction of "waste free city".

In order to achieve the high-quality development of green buildings, recently, the Special Plan for the Development of green Buildings in Zhongshan City (2022-2035) (hereinafter referred to as the "Plan") was issued, which represents that green buildings in Zhongshan City are moving towards a new journey of high-quality development, and further help the construction of "waste free city".

In accordance with relevant planning requirements such as national economic and social development planning, the Plan defines the development goals, divisions and tasks of green buildings in Zhongshan City in accordance with the principle of "adapting to local conditions, moderately ahead, overall consideration and highlighting key points", integrates the green building design concept into the technical standard system of Zhongshan City's territorial spatial planning, and comprehensively constructs civil buildings in accordance with green building standards. Key areas and important buildings are built according to the star-rated green building grade to continuously meet the people's demand for quality housing.

Zhongshan Green building Project

Build high-quality civil buildings

Green building refers to high-quality civil buildings that save land, water, energy, building materials and other resources, protect the environment, reduce pollution, provide people with healthy, applicable and efficient use of space, and realize harmonious coexistence between man and nature during the whole life of the building. The promotion of green buildings can prevent and reduce the generation of construction waste in the construction process from the source, and effectively reduce the discharge of construction waste during the whole life of the project, which is an important measure to practice "no waste".

In recent years, Zhongshan City has focused on green and low-carbon development in the field of residential construction, taking green buildings as the starting point, focusing on quality buildings of "applicable, economic, green and beautiful", carried out green building creation actions, promoted the accelerated development of green buildings in Zhongshan City, and deepened the innovation transformation and upgrading of the construction industry. The annual proportion of green building applications is 88.29%. Among them, the star-rated green buildings accounted for 23.2%, and achieved phased results.

"By leading the high-quality development of green buildings, accelerating the energy-saving and green transformation of existing buildings, establishing a green and low-carbon technology system, and promoting the development of green industries, there are three main benefits for urban development: promoting a healthy lifestyle, saving energy and resources, reducing carbon dioxide emissions, and providing a more comfortable living environment." Zhongshan City housing and urban and rural development Bureau responsible person introduced.

Green building is the future

For urban development and citizens' living experience, green buildings have certain advantages. Gao Jie believes that "promoting the landing of green buildings is the future trend of real estate company development and environmental protection."

With growing concerns about climate change, resource shortages and environmental pollution, the demand for green buildings has also grown, he said. Green buildings can reduce the consumption of natural resources, reduce carbon emissions and reduce the generation of construction waste.

At present, green building has become the key support field of green finance in China. Among them, the "Green Bond Issuance Guidelines" issued by the National Development and Reform Commission clearly lists green building development as a key support project.

"While the initial costs of green buildings may be high, the long-term economic benefits are significant. Green buildings can reduce energy and water consumption, reduce operating costs, and increase asset value. At the same time, it can also increase the attractiveness of tenants and buyers, improve the rental rate and retention rate." "In addition, as households' demand for healthy living continues to upgrade and the national 'double carbon' strategy targets are formulated, green buildings are becoming more and more popular and even become the mainstream trend of improved housing." Now the energy conservation requirements for buildings are generally increased, we have been taking green differentiated development as an enterprise strategy, in this regard, the layout in advance, many projects of the building energy efficiency standards are higher than the national requirements, the cost of doing green buildings is not very high."

To build a number of high star green buildings

"Green buildings are ecological buildings, sustainable buildings. The green building can provide a more comfortable living environment is determined by its own nature, and its content includes not only the building itself, but also the ecological function system of the internal and external environment of the building and the stable ecological service and maintenance function system of the construction of community safety and health." Zhongshan City housing and urban and rural development Bureau responsible person introduced.

At the same time, he said that Zhongshan City in the promotion of green building development still has the overall technical level is not high, scientific and technological innovation ability is not strong and other difficulties, due to the lack of green building development encouragement policies and incentives, green building related technologies, products and other development lag, enterprises generally lack technology and product research and development investment, the transformation and application of the results of the project is insufficient.

"In response to these problems, we have also launched some measures to promote the construction of the existing building energy efficiency supervision system." The person in charge said.

In order to further grasp the energy efficiency application level of buildings and rationally evaluate the energy use of buildings, from 2021 to 2023, Zhongshan City has organized various towns and streets to complete the energy and resource consumption statistics of more than 600 civil buildings, the energy audit of 45 public buildings and the construction of 15 building energy consumption monitoring devices. Continuously expand the coverage of energy consumption statistics, improve the breadth and depth of energy auditing, tap the value of energy consumption monitoring data, give play to the evaluation efficiency of energy efficiency evaluation in the process of energy saving transformation, and actively guide the public buildings in Zhongshan City to save and use energy efficiently.

In addition, Zhongshan City is also actively carrying out the pilot demonstration of ultra-low energy consumption buildings, in the north of Xiaolan town (Fuxing New Village) near zero carbon emission zone community can be replicated and promoted on the basis of the experience, is orderly promoting the zero carbon city pilot in Cui Heng New Area and Modao Island, Zhulpai Island near zero carbon emission zone town pilot construction work.

The relevant person in charge of the Zhongshan City Housing and Urban-Rural Development Bureau said that next, Zhongshan City will implement the requirements of the "Planning" and other documents, focus on the carbon emission control goals of green buildings and construction fields (2021-2030), create a number of high-star green buildings in Zhongshan, and explore the construction of Lingnan ultra-low energy consumption buildings. Explore green construction technology route, construction supervision measures, acceptance mechanism and property operation scheme suitable for Zhongshan, study appropriate passive energy-saving measures, energy utilization methods and green building materials utilization methods, and make construction (renovation) implementation plans and green building layout plans for green buildings of different types of civil buildings. And formulate the layout plan of new and existing green ecological urban areas, communities and residential demonstration areas, and put forward targeted construction proposals.
