Abstract:

The park is a core component of industrial agglomeration development. The construction of zero-carbon parks is significant for regions in realizing carbon peak， carbon neutrality and high-quality development. Since functional parks， such as business parks， logistic parks and campuses， are of clear carbon emission sources，apparent paths for carbon reduction and good demonstration effects，these parks are the key to zero-carbon park construction. To facilitate the construction of zero-carbon functional parks， a replicable implementation method should be formulated. The related definitions， industrial development status and related policies of zero-carbon parks are summarized. According to the characteristics of the energy demand and carbon emissions of functional parks，a five-step method for zero-carbon park construction is proposed， which includes assessment on carbon emission，analysis on key zero-carbon technologies，planning of park reconstruction，system operation monitoring and comprehensive evaluation. Taking a business park as the example， the key factors affecting the cost and benefit of the park taking zero-carbon reconstruction are analyzed， and the comprehensive evaluation on relevant indicators is conducted. The results show that the payback period of the IEC park is eight years，and its cost and benefit are highly related to the installed capacity of PV units and trading price of carbon sink. If 50% park area is covered with PV modules， and the trading price of carbon sink reaches at 500 yuan/t，the payback period can be reduced to 6.7 years. The proposed planning method of functional zero-carbon parks can be widely used in various scenarios， such as office areas，campuses and hospitals.
