Green building practices are becoming increasingly relevant in Vietnam as the country experiences rapid urbanization, industrial growth, and expanding real estate development. Developers and manufacturers are increasingly seeking internationally recognized sustainability frameworks to improve building performance, reduce operational costs, and meet environmental goals. One of the most widely adopted certification systems for emerging markets is EDGE (Excellence in Design for Greater Efficiencies), developed by the International Finance Corporation (IFC).
EDGE focuses on measurable reductions in energy use, water consumption, and embodied energy in materials, making it particularly suitable for fast-growing construction markets such as Vietnam. Achieving EDGE certification requires technical expertise in energy modeling, material analysis, and sustainable design strategies. As a result, developers often rely on specialized sustainability consultancies to guide projects through the certification process.
This article reviews several international consultancies that provide EDGE-related sustainability advisory services and green building expertise, many of which support projects across Asia, including Vietnam.
