National zero-carbon settlement! Jiashan builds a low-carbon zero-carbon leading area and model room in the Yangtze River Delta

"This is a true zero-carbon settlement in China. Renewable energy sources such as wind energy, geothermal energy, solar energy, biomass energy, and hydrogen energy are used to complement each other and achieve carbon balance." Chief Engineer of the China Urban Science Research Society and China Ecological City Research Shen Lei, executive vice president of the institute and chief engineer of the Jiashan area of the demonstration zone, made an calculation: the total electricity consumption of the Zhuxiaohui dual-carbon settlement can reach 1.18 million kilowatt-hours per year, and the photovoltaic power generation on the building's roof reaches 1.2 million kilowatt-hours per year. Energy self-sufficiency. In addition, the total power consumption of electric vehicles in the settlement is about 100,000 kilowatt-hours per year, while wind power generation plus photovoltaic equipment outside the roof generates electricity of about 100,000 kilowatt-hours per year, which is a complete balance between electricity consumption and power generation.

In order to achieve the high-quality carbon peaking goal of the Yangtze River Delta Ecological Green Integrated Development Demonstration Zone and give full play to the integrated synergy and demonstration leading role of the integrated demonstration zone in the Yangtze River Delta Carbon Peaking Action, the Demonstration Zone Executive Committee, together with the two provinces, The Municipal Development and Reform and Ecological Environment Department formulated the "Carbon Peaking Implementation Plan for the Yangtze River Delta Ecological Green Integrated Development Demonstration Zone" and listed the Jiashan Xiangfudang Innovation Center as a key area for carbon peaking work, requiring vigorous exploration of reducing sources and increasing sinks. , alternative near-zero carbon path, and integrate into the Yangtze River Delta low-carbon and zero-carbon leading area and model rooms.

The Zhuxiaohui dual-carbon settlement with a total land area of 118,000 square meters has become a model for the model room - the construction waste generated after the original building was demolished is used as decorative materials for the new building; the sewage and wastewater are reused and discharged after treatment; the kitchen Remaining garbage and other waste are processed locally through biodegradation, and other domestic waste is collected, processed and reused in a classified manner; low-carbon smart city facilities such as contactless smart trash cans, photovoltaic power generation landscape racks, smart solar charging chairs, smart street lights, energy storage charging piles, etc. Products at your fingertips.

Beyond the living space of zero-carbon buildings, near-zero carbon concepts and technologies have also been rooted in production and ecological spaces - 400 acres of low-carbon smart farmland saves 50% of water and reduces carbon by 20%; the ecological island sees fireflies in summer and fireflies in winter. A flock of migratory birds. "We are conducting comprehensive dual-carbon experiments in Zhuxiaohui, including farmland carbon reduction, building zero-carbon, and ecological island carbon sequestration." Shen Lei said, hoping to move from Zhuxiaohui to Xiangfudang to the Yangtze River Delta, from a single settlement to a park Moving to urban areas, we will step by step explore a dual-carbon model that is universal, economical, practical, popularizable, replicable, and implementable.

"This place has gradually transformed from a weak point at the junction of two provinces and one city into the current forefront of reform and development. In the future, this place will be an observation window for eco-friendly and high-quality development." Deputy Director of the Zhejiang Provincial Development and Reform Commission and Demonstration Zone Chen Jianzhong, deputy director of the Executive Committee, said.
