Wanwei Wuhan Dongxihu Cold Chain Park upholds the principle of sustainable development, creating a benchmark national cold chain park project aimed at enhancing intelligent, visualized, and lean warehousing information systems. It strives to build a green, energy-efficient, and environmentally friendly cold chain distribution center. Recently, the park received the highest-level Tier 1 Green Warehouse certification from the China Association of Warehousing and Distribution, and the Gold certification for LEED BD+C: Warehouses and Distribution Centers from the U.S. Green Building Council.
Wanwei Wuhan Dongxihu Cold Chain Park is the first high-standard cold chain intelligent park built by Wanwei in Wuhan. It is a three-story ramp park with a total construction area of about 90,000 square meters and a cold storage capacity of nearly 57,000 tons. Located in the premium area of Dongxihu District, the park includes all temperature zones such as frozen, refrigerated, constant temperature, and ambient temperature. It also has value-added service areas like food processing to meet the diverse needs of various customers, providing comprehensive cold chain logistics services to leading chain enterprises such as Walmart and Yum!
In the initial design phase, special meetings were held to discuss the energy-saving intelligent system of the park, responding to the “dual carbon” goals and practicing green concepts. The park is designed with solar photovoltaics and automation systems, with heat recovery from refrigeration used for floor heating and antifreeze in cold rooms. Energy-consuming equipment is chosen based on energy-saving standards. The park employs intelligent temperature control, intelligent refrigeration, intelligent fire protection, and intelligent security systems to ensure the storage, distribution, and environmentally friendly operation of the park.
All warehouse roofs in Wanwei Wuhan Dongxihu Cold Chain Park (three cold storage buildings) are covered with photovoltaic panels, using high-efficiency photovoltaic modules with a conversion efficiency of up to 21.2% and inverter efficiency of 98.6%. The roof area is 22,638 square meters with a total installed capacity of about 3.19 MW. Preliminary estimates suggest that the annual average power generation from the rooftop photovoltaics is about 3.03 million kWh.
Adicionalmente, Wanwei Wuhan Dongxihu Cold Chain Park utilizes a fully automated warehouse system. Compared to traditional rack warehouses, the energy-saving rate of the automated warehouse system is as high as 33%. The automated warehouse doors are smaller than traditional ones, significantly reducing cold air leakage. Furthermore, the automated system’s dark operation mode reduces lighting electricity consumption compared to traditional cold storage. The double-deep stacker system has a real-time energy feedback function, also contributing to energy savings. From the perspective of rack height and efficiency, traditional industry racks generally have 5-6 layers, whereas Wanwei Wuhan Dongxihu Cold Chain Park’s automated racks reach 15 layers. The operational efficiency of the automated warehouse is 195 pallets/hour, peaking at 228 pallets/hour, which is 2-3 times the efficiency of manual operations. The automated warehouse features imported hydraulic buffers and world-class control technology and hardware. The warehouse adopts a conveyor + linear shuttle car mode, making the equipment compact and flexible, greatly saving corridor space and reducing the time goods stay in the corridors.
Based on the ASHRAE90.1-2010 Energy Standard for Buildings Except Low-rise Residential Buildings, the project’s energy-saving rate exceeds 50%.
As of June 30, 2023, Wanwei’s cumulative green building certification area exceeds 7.7 million square meters, with 101 projects obtaining three-star green certification. Twelve cold chain parks have received LEED Platinum/Gold certifications (including seven Platinum and five Gold). In the future, all new cold storage facilities will aim for 100% green warehouse certification and 100% coverage of distributed photovoltaics.
