Vietnam’s construction sector has experienced rapid growth over the past decade, driven by urbanization, foreign investment, and large-scale infrastructure development. Alongside this growth, sustainability and energy efficiency have become increasingly important priorities for developers, international investors, and government institutions. As a result, LEED (Leadership in Energy and Environmental Design) certification has become one of the most widely recognized green building standards used in Vietnam.
LEED-certified buildings help reduce energy consumption, improve indoor environmental quality, and lower long-term operational costs. Achieving certification, however, requires specialized expertise in sustainability strategies, energy modeling, documentation management, and compliance with international green building standards. This is where experienced LEED consultants play a crucial role.
Below are several international consultancy firms involved in sustainability and green building advisory services, including companies capable of supporting LEED certification projects in Vietnam and across Asia.
1. ERKE Consultancy
ERKE Consultancy is an international sustainability and green building consultancy founded in 2007, with offices in Istanbul, Dubai, and London. The company has completed more than 200 LEED-certified projects across 15 countries, ranging from Europe and the Middle East to Asia.
ERKE provides comprehensive LEED consultancy services, supporting projects from early design strategy through final certification. The firm’s team includes LEED Fellows, LEED APs, BREEAM Assessors, WELL APs, EDGE Experts, and product sustainability specialists. This multidisciplinary structure allows ERKE to manage complex certification processes while integrating sustainability strategies into architectural and engineering design.
The company has extensive experience working on large-scale developments, including airports, hospitals, commercial headquarters, and mixed-use projects. Notable examples include the Bahrain International Airport (200,000 sqm, LEED Gold), Istanbul Çam Sakura Hospital (1,000,000 sqm, LEED Gold), and Allianz Istanbul Headquarters (LEED Platinum).
In addition to building certifications, ERKE also provides product sustainability services such as Life Cycle Assessment (LCA) and Environmental Product Declarations (EPDs). The company has worked with international manufacturers including Nippon Paint, Polisan, Çimsa, and USG Boral. This expertise enables ERKE to support projects where both building performance and sustainable materials are key priorities.
