Vietnam’s construction sector has experienced rapid growth over the past decade, especially in major urban centers such as Ho Chi Minh City, Hanoi, and Da Nang. As international investors, technology companies, and manufacturing groups expand their presence in the country, sustainable building standards have become increasingly important. Among these standards, LEED (Leadership in Energy and Environmental Design) has become one of the most recognized green building certification systems for commercial developments, industrial facilities, and large-scale mixed-use projects.
Developers pursuing LEED certification in Vietnam typically require specialized consultancy services to manage sustainability strategies, documentation, energy performance modeling, and coordination with international certification bodies. Several international consulting firms operate globally in this field, supporting projects that aim to achieve high levels of environmental performance and operational efficiency.
Below is an overview of several international LEED consultancy firms with experience in sustainable building and environmental certification projects.
