As Vietnam increasingly strengthens its position as a strategic manufacturing hub in Asia, the wave of FDI enterprises continues to expand with rising expectations for construction quality, operational efficiency, and sustainability aligned with ESG (Environmental, Social, and Governance) standards. 

Investors from Japan, South Korea, Taiwan, China, Europe, and the United States are no longer looking for contractors who simply “build a factory.” They seek a partner with a sustainability-driven mindset, one who can embed durability, energy efficiency, and compliance into the design so that the facility operates reliably for 20 - 30 years while meeting international benchmarks. 

This is why FDI manufacturers choose NSN, a Design & Build (D&B) General Contractor with over 20 years of experience in industrial construction and renewable energy, trusted for turning challenges in cost, operation, and ESG compliance into long-term competitive advantages.

1. Optimized Energy Design – A Foundation Aligned with ESG Goals 

Operating costs are often the “long-term burden” of FDI factories. Energy efficiency, therefore, becomes both a competitive advantage and a key factor contributing to the Environmental (E) component of ESG. NSN approaches design by optimizing every kilowatt-hour of energy consumption from the first step. 

Key solutions include: 

• CFD (Computational Fluid Dynamics) simulations to optimize airflow, heat distribution, and ventilation to reduce cooling loads. 

• Daylighting and natural ventilation strategies to minimize dependence on artificial lighting and HVAC systems. 

• BMS/EMS - Smart building and energy management systems, enabling real-time monitoring, control, and performance analytics, integrated with rooftop solar and BESS. 

• Renewable energy integration, including rooftop solar systems compliant with Vietnam’s current renewable policies, reducing grid electricity consumption by 10-20%. 

• High-efficiency MEP systems, selecting energy-efficient HVAC, LED lighting, and equipment to reduce operational losses. 

With these solutions, factories can reduce energy operating costs by 20–30% annually, a significant driver of long-term ROI for FDI manufacturers. 

 2. Water & Resource Management

Effective water and resource management is essential for meeting ESG requirements and environmental regulations. NSN adopts a closed-loop, circular-resource approach to ensure compliance with stringent standards from global investors. 

Solutions include: 

• Collection, treatment, and reuse of rainwater and treated wastewater for appropriate applications. 

• Separation of domestic and industrial wastewater to enhance quality control and minimize environmental risks. 

• High-efficiency cooling water systems that reduce power consumption and extend equipment lifespan. 

These measures help factories reduce water-related costs while demonstrating strong environmental responsibility. 

3. Sustainable Materials – Built to Endure 

To align with ESG objectives and ensure sustainable durability, construction materials must be environmentally friendly, highly durable, and low-maintenance. 

NSN implements: 

• Eco-friendly materials with green certifications, such as low-VOC, non-fired bricks, low-density cement, recycled steel, clinker-reduced cement, low-E glass, high-efficiency motors, and FSC-certified timber. 

• Modular structural designs that enable flexible expansion or production changes. 

• Material waste minimization, optimizing resource usage for investors. 

This philosophy of “building sustainable construction” is reflected in even the smallest design details. 

4. BIM & Digital Technologies – The New Standard for FDI Factories

A modern factory requires a “digital brain” at the design stage to optimize construction processes and operational management, an essential part of the Governance (G) criteria in ESG. 

NSN applies: 

• Building Information Modeling (BIM) to detect technical clashes early, reduce material waste, improve accuracy, and enhance transparency. 

• Lifecycle asset management simulations using BIM data to accurately predict maintenance costs. 

• IoT and automation systems to standardize operation, improve reliability, and enhance maintenance efficiency. 

These digital capabilities are key reasons why leading electronics, high-tech, and precision engineering manufacturers choose NSN as their D&B partner. 

Strategic Benefits for FDI Enterprises 

Sustainable design is not a “luxury" choice. It is a strategic investment that shapes sustainable competitiveness: 

✔ Significant reduction in operating expenses and improved long-term ROI 
✔ Full alignment with ESG standards 
✔ Lower environmental risks and strong compliance with Vietnamese regulations 

✔ Enhanced workforce attraction through a high-quality workplace environment (ESG – Social) 
✔ Strengthened brand reputation, supporting future expansion in Vietnam 

Investing in sustainable design is investing in the future performance of the factory. 

A Sustainable Journey Begins with the Right Blueprint 

When an FDI enterprise chooses to build a factory in Vietnam, it is committing to a sustainable vision. NSN stands ready to accompany that journey as a professional and transparent Design & Build General Contractor, where quality and sustainability come first.
