Jian Yan City | Building a "Zero Carbon City" to Promote Ecological livability

Source: Urban Construction News Channel

With the high-quality development of China's economy, the acceleration of the new urbanization process, and the continuous improvement of residents' living standards, the people's yearning for a green ecology and a beautiful China has become more urgent. This year's Report on the Work of the Government again focused on "carbon reduction", specifically proposing to promote green transformation of the development mode, improve policies to support green development, develop a circular economy, and respond to the people's expectations for green and low-carbon development with more powerful policy measures.

To implement "carbon reduction", it is not only necessary to formulate a macro policy system at the national level, but also to be specific to each city, and even to the "cellular units" of each city - communities. Communities are not only the main places for people to work, live, and reside, but also an important spatial carrier for cities to practice the "dual carbon" concept. Therefore, promoting "carbon reduction" should not only focus on the supply side, but also on carbon emissions in urban communities. Especially with the acceleration of industrialization and urbanization, the carbon emissions of residents' lives are constantly increasing. If residents can practice low-carbon emission reduction in their communities and promote the construction of a "zero carbon city", it will be greatly beneficial for achieving the "dual carbon" goal. How to build a "zero carbon city" requires efforts in areas such as increasing greenery and reducing carbon emissions.

Increase the "green content" of urban communities

The "green content" reflects the "gold content" of the construction of a "zero carbon city". Improving the green coverage rate of urban communities is an important part of the blueprint for a "zero carbon city". Continuously increasing the "green quantity" of the community, improving the quality of greening, and bringing residents' dreams of seeing green through windows into reality through various methods such as demolishing violations and returning green, inserting green through gaps, breaking through hard and increasing green, and vertical greening. In addition, to build a "zero carbon city", it is necessary to accelerate the green construction of urban public infrastructure, combine the renovation of old residential areas, garbage classification, and reasonably set up various sponge facilities such as green roofs and rainwater gardens on roads, green spaces, and buildings, to avoid and solve the problem of urban waterlogging and water accumulation, improve the effectiveness of creating a "zero carbon city", and achieve the goals of clean urban environment, green and low-carbon, energy conservation and carbon reduction.

Increase carbon reduction in urban communities

The 'carbon reduction' reflects the 'golden value' of the construction of a 'zero carbon city'. Based on the actual level of economic development in various regions of China, the carbon emission intensity during the operation of buildings in various urban communities is set to minimize carbon emission standards while not affecting the quality of economic development. By comprehensively utilizing seawater source heat pumps, solar photovoltaic photothermal, wind power generation, sewage source heat pumps, industrial waste heat and other technical measures in cities according to local conditions, we aim to achieve efficient and clean energy supply in cities; By building community rooftop photovoltaic power stations, integrated photovoltaic building curtain walls, and other facilities, we aim to achieve green supply of domestic energy; By constructing an efficient oil fume purification system and a primary energy efficient variable frequency air conditioning system, energy-saving transformation can be achieved. Technologies such as building wall insulation mortar and energy-saving aluminum alloy windows are used to achieve energy-saving transformation of the building body, achieving the effect of "roof power generation and indoor energy conservation"; By embedding photovoltaic panels in public places such as lighting, benches, and parking lots, solar energy can be absorbed and stored to convert into photovoltaic energy, further reducing consumption and carbon emissions, and achieving the "dual carbon" goal of energy harvesting.

Enhancing the "Smart Power" of Urban Communities

The "wisdom" reflects the "gold content" of the construction of a "zero carbon city". Combining the construction of "zero carbon cities" with the construction of smart cities, focusing on building a smart energy management system, continuously optimizing the energy structure of urban communities, increasing the proportion of green energy in urban community consumption, and achieving smart management of energy consumption, energy efficiency evaluation, energy scheduling, and safety assurance. Specifically, in urban communities, by integrating new technologies and achievements in the fields of big data, cloud computing, and the Internet of Things, a complete urban service system is formed to achieve digitalization of life, transportation, healthcare, safety, and environment. Smart services in areas such as clothing, food, housing, and transportation are provided to residents, helping to reduce their individual carbon emissions and promoting them to enjoy more convenient, efficient, and low-carbon urban life, forming a green, low-carbon Healthy lifestyle.
