Green Engineering Management

Green Engineering Management

In response to the global focus on corporate carbon reduction efforts, Acter has gradually phased out old production processes and focused on developing high-value, low-power consumption and low pollution technologies, while enhancing green procurement practices and integrating them into engineering operations. With our dedication to developing various green technologies and establishing green engineering project management procedures, we aim to install high-value, low-power consumption, and low-pollution green factory facilities to minimize the impact of factory operations on land, air, water, and natural ecological systems. Considering that significant energy can be consumed throughout the entire life cycle of engineering construction projects, we start from the initial planning and design stages to enhance energy efficiency and minimize environmental impact. This approach not only reduces customers' operating costs but also facilitates the efficient distribution of energy resources while decreasing greenhouse gas emissions. Moreover, we actively propose optimal green solutions to customers, assisting them in planning, designing, and constructing green buildings to advance the industry's transition to net-zero emissions.

Green Engineering Project Management Process
01
 Communication with customers regarding their demands 
  • Engage in thorough communication with customers to optimize business scale and resource utilization, while avoiding over-design.
  • Provide professional "green value engineering solutions" tailored to customers' specific demands and budget. These solutions are presented to customers for evaluation and selection, creating new opportunities for the green economy.
02
 Overall planning and design 
  • Plan the overall integration of energy-saving equipment, eco-friendly materials, and low-pollution design, while conducting performance analysis.
  • Utilize Building Information Modeling (BIM) for precise calculations, increasing construction accuracy, reducing the risk of pipeline conflicts, and minimizing material waste.
  • Effectively employ Virtual Reality (VR) technology to facilitate discussions with customers regarding site pipelines and space configuration. This allows for thorough communication and minimizes time and manpower waste.
BIM
  • 2D,3D & VR 
03
 Green procurement 
  • Establish a standard system and procedures to effectively control resource inventory, adjust demand accordingly, and improve procurement performance.
  • Strengthen green supply chain management by reviewing the specifications of green products and equipment, and systematizing all resources.
Intelligent Management
  • ERP / PLM
04
 Green engineering techniques 
  • Implement PLM (Product Lifecycle Management) project standardization management for efficient and instant communication.
  • Integrate prefabricated components, modularized piping and wiring, automated monitoring equipment, and various other green engineering techniques to effectively enhance resource utilization efficiency and reduce costs.
ISO Management System
05
 Environmental recovery/resource recycling 
  • Materials used on the project site should be shipped in batches to avoid excessive raw materials. Any materials that have been excessively ordered shall be repurchased by the suppliers or the information regarding the excess shall be entered into the procurement system for use by other units. These measures can effectively reduce and control leftover materials.
  • Provide customers with a proper maintenance and repair strategy to decrease equipment wear and tear rates and equipment replacement rates.

The air duct system is designed with a airfoil blade backdraft damper The airfoil blade, in the fully open position, has lower static pressure loss compare to a three-vane blade, reducing the power required for the fan shaft and lowering energy consumption.
The low-humidity air-conditioning chemical desiccant wheel features an energy-saving plate heat regenerator that recovers regenerative power in full. Recycling the high-temperature exhaust of regenerative electric power to preheat the temperature of regenerated makeup air. This can reduce approximately 10% to 17% of regenerative electric power, thereby decreasing the power consumption/ carbon emissions.
