Green Engineering Management

Green Engineering Management

In response to the growing global awareness of sustainable development, we have integrated the United Nations Sustainable Development Goals (SDGs) into our green engineering management framework. By fostering new thinking and opportunities within our core operations, we adopt advanced environmentally friendly and energy-efficient technologies throughout project execution. We have established green engineering project management processes to deliver high-value, low-energy-consumption, and low-pollution facility systems for our clients, thereby reducing the ecological impact of business operations.

Acter is committed to enhancing energy efficiency and reducing environmental impact by offering a comprehensive suite of green technology services that align with environmental protection standards. These solutions help clients lower operational costs, optimize energy and resource utilization, and reduce greenhouse gas emissions. In collaboration with our clients, we promote the planning, design, and construction of green buildings—delivering optimal solutions for property owners and contributing to the industry’s transition toward net-zero emissions and a more sustainable future.

Adhering to a life cycle management approach, Acter integrates sustainability considerations throughout every stage of a project—from design, material selection, and transportation to construction, usage, and demolition. Through our internal procurement system and surplus material control mechanisms, we ensure efficient resource reuse and incorporate circular economy principles into our engineering and construction processes. This approach effectively reduces waste generation and supports a green, circular, and sustainable business model.

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.
