Hangzhou Gongshu District creates a "new green model" for pollution reduction and carbon reduction
Gongshu District, Hangzhou City, Zhejiang Province, has taken the lead in the track of synergy in pollution reduction and carbon reduction, focusing on extending the depth, maintaining the intensity and expanding the breadth, digging deep into the carbon reduction potential in the field of green buildings, and driving carbon reduction in the three major fields together.
Promote large-scale commercial complexes to tap the carbon reduction potential of green buildings
To save energy and reduce carbon emissions, we must focus on key industries. The construction sector is one of the key industries for the implementation of energy conservation and carbon reduction, and has made outstanding contributions to reducing carbon emissions. Improving the energy efficiency of buildings can unleash the potential of energy conservation and carbon reduction in the building sector.
Hangzhou Joy City is a landmark commercial complex in Hangzhou, covering an area of 57,259 square meters and a construction area of 233,454.11 square meters. The project adopts the contract energy management model, and carries out energy-saving upgrades to the air-conditioning system, basement lighting system and kitchen exhaust fume system, achieving annual power savings of about 2.1 million kilowatt hours, annual saving of about 1,082 tons of standard coal, and annual reduction of CO2The emission is about 2,697 tons, and the comprehensive energy saving rate reaches 35.8%. It has successively won the honorary titles of "Zhejiang Green Shopping Mall", "Hangzhou Energy Conservation Demonstration Project" and "RICS Sustainable Development Award", and was selected by the Ministry of Housing and Urban-Rural Development as a "National Advanced Typical Case of Carbon Peak and Carbon Neutrality in the Field of Urban and Rural Construction".
The three major areas go hand in hand to implement pollution reduction and carbon reduction
Gongshu District has carried out pollution reduction and carbon reduction work in the fields of energy, industry and construction.
In the energy sector, we will implement "source saving and flow control" and carry out capacity building for load peak regulation. In the first half of the year, Gongshu District completed 17,410 kilowatts of load peak regulation capacity. Among them, 8,300 kilowatts of grid-connected photovoltaic projects and 2,900 kilowatts of projects under construction. Two new energy storage projects have been developed, namely the industrial park energy storage project and the charging station photovoltaic storage project, with a total installed capacity of 280 kilowatts. The total load access capacity of air conditioning is 124,500 kilowatts, and the installation of transformer capacity of more than 2,000 kVA has been basically completed. Secondly, the implementation of intelligent energy-saving renovation of buildings. In the first half of the year, the energy-saving renovation project of Tianyang D32 fashion shopping block has been completed, and the energy efficiency of the project has been improved through the energy-saving renovation project. Kangqiao Industrial Park has carried out the transformation and upgrading of inefficient industrial land, and has signed a relocation agreement for 16 enterprises, and in the first half of this year, it has been determined to vacate 1,448 tons of standard coal. The freed up energy consumption space will be used to balance the energy consumption indicators of the region.
In the industrial field, "cages for birds". Gongshu District will speed up the rectification of high-consumption and low-efficiency enterprises, promote a new round of manufacturing industry "free cages for birds, phoenix nirvana" action, further promote the transformation and upgrading of inefficient industrial land in Kangqiao Industrial Park, adhere to the principle of "list promotion, closed-loop management", and carry out rectification and upgrading by shutting down and withdrawing, so as to make room for development for projects that are in line with industry orientation and have high land use efficiency and per mu tax. Promote the construction of green manufacturing system. Promote the application of new energy and energy-saving technology and equipment in high-energy-consuming industries and traditional manufacturing industries. Encourage enterprises to adopt new technologies, new processes, new equipment, and new materials to transform and upgrade production implementation, process conditions, and production services, and improve the production level of enterprises. Build a green energy industry ecosystem. The new material and new energy industry will be included in the 1+4+N leading industries in the region, and the "chain master" enterprises of the photovoltaic industry such as Hoymiles Power will be cultivated as the starting point, and the "chain" service will be strengthened, and efforts will be made to build a green and low-carbon industrial system. At present, there are 16 key industrial enterprises in the energy conservation, environmental protection and new energy industries in the region, such as Hoymiles Power, Chuhuan Technology, and Tianfeng Power.
On this basis, we should pay attention to "energy efficiency improvement" in the construction field. Carry out high-star green building demonstration projects, ultra-low energy consumption building demonstration projects, near-zero energy building demonstration projects and other annual green building and building energy conservation project reserves and organize implementation. Carried out solar photovoltaic projects in civil buildings: a total of 3,879.68 kilowatts of installed solar photovoltaic capacity of new buildings have been completed. Implement the energy efficiency improvement and renovation of public buildings, carry out energy-saving renovation projects for commercial complexes and government offices in the jurisdiction, and vigorously promote the energy efficiency improvement of public buildings in Gongshu District. Cultivate green eco-urban areas, and continue to increase efforts to explore green eco-urban projects with the construction of the north of the city as a platform.
The blueprint leads the way and comprehensively strengthens the background of green development
In terms of top-level design, Gongshu District has systematically planned the synergy of pollution reduction and carbon reduction, formed a work pattern of coordinated promotion of pollution reduction and carbon reduction, and systematically promoted energy conservation and carbon reduction.
First of all, we need to formulate a "blueprint pilot" for carbon peaking action plan. In July 2021, a third party was entrusted to compile an action plan for peaking carbon dioxide emissions in Gongshu District (including the former Xiacheng), which was preliminarily reviewed by experts, negotiated by the soliciting department, and revised and improved. It is estimated that the carbon emissions of Gongshu District will peak in 2028, with a peak carbon emission of 5.525 million tons, achieving the target ahead of schedule. A leading group for "dual carbon" work has been established as a guarantee for promotion. In September 2021, the Gongshu District Party Committee and the District Government established the Gongshu District Carbon Peak and Carbon Neutrality Leading Group to coordinate and promote carbon reduction, promote the low-carbon transformation of the industry, curb the blind development of the "two high" projects, promote the application of new energy such as photovoltaics, realize the adjustment of energy structure, build a clean and low-carbon energy system, and achieve the "double carbon" goal.
Secondly, the "dual carbon" digital intelligence platform is applied to achieve "one network unified management". In accordance with the idea of digital reform, relying on the energy "double carbon" digital intelligence platform built at the municipal level, 241 annual key energy-using units in the region have been included in the supervision, and the "dual control" of energy consumption and carbon emissions of key energy-using units have been budgeted, real-time and accurately controlled. Through the platform, the energy consumption budget target is directly issued to the key energy-using enterprises, and the online monitoring of energy consumption data and the automatic early warning function of energy consumption are used to ensure that the total energy consumption of large energy users will not exceed the standard.
Thirdly, the social energy conservation and carbon reduction "point line into surface". The Gongshu Ecological Branch actively builds low-carbon cells, improves and improves the "cells" in an all-round way from the aspects of low-carbon concepts, green production capacity, and participation paths, and 10 communities in the district have been successfully included in the third batch of low-carbon (zero) carbon community creation lists in the province. In addition, Gongshu District has completed the creation of 32 "energy-saving institutions", with the creation of energy-saving institutions as the carrier, improve the system of energy conservation and resource conservation, strive to implement green office, take the lead in the implementation of domestic waste classification, vigorously carry out conservation culture, green life publicity and education, reduce the operating costs of organs, improve administrative efficiency, better play the role of party and government organs in demonstration and leadership, and promote the formation of a good atmosphere of 'strict economy and opposition to waste' in the whole society. At the same time, Zhejiang Provincial Archives participated in the selection of green buildings and obtained the two-star green building label certificate, becoming a demonstration unit of green buildings. At present, the district government canteen is in the process of applying for the green canteen of the provincial public institution.
In the next step, Gongshu District will handle the relationship between key tackling and collaborative governance, strengthen departmental coordination, regional coordination, and policy coordination, and continuously enhance the systematic, integral, and collaborative nature of various work. Handle the relationship between high-quality development and high-level protection, focus on building a green, low-carbon and circular economic system, effectively reduce the resource and environmental costs of development, and continue to enhance the potential and stamina of development. Handle the relationship between the "dual carbon" commitment and independent action, and use your own path and method, rhythm and intensity to achieve the "double carbon" goal.
