Common Mistakes in Green Building Implementation and How to Fix Them

Amid the global shift toward sustainability and Vietnam’s Net Zero 2050 commitment, green buildings are becoming a top choice for many businesses and investors. However, in practice, many projects face difficulties during implementation due to common mistakes in green building, leading to higher costs or failure to obtain international certifications such as LEED and EDGE.

So, what are the most common mistakes in green building implementation, and how can they be solved to maximize project efficiency?

1. Lack of Early Direction in the Design Phase

– Common mistake: Focusing only on architecture and aesthetics without integrating green criteria from the beginning. Adding them later during construction results in high costs and difficulty achieving certification.
– Solution: Develop a green strategy from the design stage. Engage LEED/EDGE/BREEAM consultants early to optimize materials, technology, and energy-saving solutions.

2. Choosing Inappropriate Materials

– Common mistake: Selecting cheap materials without verified sources, high VOC emissions, or failure to meet environmental standards.
– Solution: Prioritize certified green materials (FSC, EPD, Energy Star, ISO 14024), recycled or renewable products, and eco-friendly alternatives.

3. Inefficient Energy Management

– Common mistake: Installing electrical, lighting, and HVAC systems without optimization, leading to energy waste.
– Solution: Implement energy monitoring systems (BMS/EMS), use energy-efficient equipment, adopt renewable energy (solar, wind), and design for natural ventilation.

4. Lack of Water Management Solutions

– Common mistake: Overlooking rainwater harvesting, wastewater reuse, or efficient irrigation systems.
– Solution: Apply water-saving technologies, recycle greywater, install low-flow fixtures, and design green landscapes to reduce irrigation demand.

5. Neglecting Operation & Maintenance

– Common mistake: After handover, buildings operate traditionally without following green standards → lowering efficiency.
– Solution: Establish green operation–maintenance procedures, train staff, and conduct periodic inspections to maintain certification.

6. Lack of Stakeholder Alignment

– Common mistake: Investors prioritize speed, contractors focus on cost savings, leading to neglect of green standards.
– Solution: Set clear coordination mechanisms among investors, consultants, and contractors, and align on green goals within contracts.

7. Unreasonable Cost Estimation

– Common mistake: Believing green buildings are too costly, without allocating budget for green solutions.
– Solution: Conduct a life-cycle cost analysis (LCCA) to prove long-term operational savings. Leverage incentives and financial support from government and green finance institutions.

Key Takeaway

To ensure successful green building projects, businesses must prepare holistically — from mindset, strategy, design, and operation — with support from professional consultants and full stakeholder commitment. Addressing common mistakes in green building early helps projects achieve international certifications (LEED, EDGE) while delivering long-term sustainable value.
