By optimizing the building’s envelope and employing natural ventilation, lighting, shading techniques, and advanced energy-efficient systems, the structure drastically curtails its energy demands. Innovative measures in air conditioning, lighting, and elevator systems have been deftly woven into its design, significantly enhancing their efficiency.


  Moreover, a holistic energy solution has been employed, merging various sources like photovoltaic power generation, integrated photovoltaic-thermal technology, and diversified energy storage. This approach not only harnesses clean energy but also recovers and utilizes low-grade thermal energy, establishing an intricate yet sustainable energy ecosystem.


  This concerted effort in energy management, encompassing clean energy utilization, waste heat recovery, and smart energy governance, represents a pivotal step towards a greener and more sustainable future. The Shenling Environmental High-tech Zone stands as a testament to the possibilities of harmonizing innovation and environmental responsibility, setting a global benchmark for specialized environmental systems’ research and manufacturing.

Definition of Zero Energy Consumption Building                                                         

  Zero Energy Building (ZEB) is an advanced form of Nearly Zero Energy Building (nZEB). ZEB maximizes the use of renewable energy resources within and around the building, ensuring that the annual renewable energy production exceeds or equals the building’s total annual energy consumption. Simultaneously, it adapts to climatic and site conditions, significantly reducing heating, cooling, and lighting needs through passive architectural design. Additionally, it employs active technological measures to maximize the efficiency of energy equipment and systems, providing comfortable indoor environments with minimal energy consumption. The indoor environmental parameters and energy efficiency indicators comply with specified standards.

High-Efficiency Large Temperature Difference Water Chilled Air Conditioning System                                                                                                

  Shenling Production Base III stands as a pinnacle of sustainable architecture—an exemplar of ‘Zero Energy Consumption Buildings.’ It employs an ultra-large temperature difference water-chilled, highly efficient refrigeration system. The system’s design maintains a chilled water return temperature of 4/17℃. Achieving an outstanding annual target energy efficiency ratio of 5.5+ (under water storage cooling conditions), the refrigeration system in the machine room excels.

  The air conditioning terminal utilizes cutting-edge technology, featuring ultra-large temperature difference series-connected counterflow and direct-current brushless motor technology. This design enables seamless operation with significant temperature variations and precise airflow regulation. Moreover, the fresh air system integrates EC fans and variable air volume controllers along the fresh air duct. This setup dynamically adjusts the airflow based on indoor CO₂ levels, ensuring on-demand supply of fresh air. Simultaneously, it responds to vertical shaft pressure by modulating fan frequency, thereby optimizing the total fresh air unit’s airflow. This strategic adjustment reduces the cooling load and energy consumption of the fresh air system.


  The annual energy efficiency ratio of the air conditioning system is maintained at ≥4.2, ensuring consistent cost-saving, carbon-reducing, and energy-efficient performance throughout the year.

  Shenling Production Base III is a ‘Zero Energy Consumption Building.’ It utilizes the park’s rooftops for the installation of solar photovoltaic panels, with an installed photovoltaic capacity of 6.41MWp. It connects to the factory’s distribution network through two 10kV grid access points. The generated electricity from the photovoltaic system meets the annual energy consumption requirements of the zero-energy building. The surplus energy, exceeding the building’s consumption, is prioritized for the park’s production needs and then integrated into the grid.

  Simultaneously, the Building itself incorporates PVT (Photovoltaic Thermal) panels and solar thermal panels on its roof. The electricity generated by the PVT panels is stored in energy storage cabinets primarily for the operation of heat pump water heaters. The heat generated by the PVT and solar thermal panels is used for preheating domestic hot water. Additionally, the outdoor ground carport of the R&D Building is equipped with photovoltaic panels. The energy storage cabinets store the electricity generated by these panels for use in new energy vehicle charging stations and office electricity.
