Vietnam is entering a new phase in construction: one that puts energy efficiency at the center of development. With buildings accounting for 35–40% of the country’s total energy consumption, the need for Vietnam Energy-Efficient Building Practices is urgent. Rising urbanization and industrial growth have made energy use in buildings a national priority. The government and private sector are responding. In 2024 alone, Vietnam doubled its number of green-certified buildings, adding 163 new certifications and bringing the total to 559. These buildings now span 13.6 million square meters, far exceeding the national targets of 80 buildings by 2025 and 160 by 2030.
This surge is more than a symbolic achievement. It also reflects a shift in how buildings are being designed, built, and operated. From LED lighting to smart HVAC systems, Vietnam’s construction sector is embracing solutions that can reduce energy use by 25% to 67%.
Vietnam Energy-Efficient Building Practices: Building Smarter from the Start
A large portion of energy savings comes from choices made during the design phase. Integrating efficient lighting, HVAC systems, and insulation can significantly reduce a building’s energy footprint. For example, switching to LED lighting can slash electricity use by up to 70%, while motion sensor systems can reduce lighting energy in specific areas by 50%.

Insulation also plays a critical role. In buildings without insulation, heating and cooling systems account for up to 65% of total energy use. When insulation is installed, that share drops to 35%, cutting overall energy demand dramatically.
These design choices don’t just reduce energy use but also pay off quickly. In a recent set of 23 buildings, technical energy-efficiency upgrades led to energy savings of 12,000 MWh and emissions cuts of 10,000 tCO₂e, with payback periods averaging just 3.5 years. The success of these retrofits has spurred the government to expand its Green Building Code, which now mandates efficiency standards for all new commercial buildings over 2,500 square meters.

A Climate and Cost Opportunity
Vietnam’s efforts are already delivering measurable results. Energy-efficient buildings have directly helped the country avoid 73,035 tCO₂ of greenhouse gas emissions to date. With rising energy costs and growing climate pressures, energy-efficient construction is not just the right thing to do—it’s the smart thing to do.
Beyond carbon savings, these buildings are financially attractive. Green-certified buildings often enjoy rental premiums of up to 7% and show higher occupancy rates than their conventional counterparts. For instance, the LEED Platinum-certified Capital Place in Hanoi reports 95% occupancy, compared to the city average of 85%. Tenants and investors are recognizing the long-term value of sustainability, with ESG-focused funds increasingly prioritizing certified projects.
The Future of Vietnam Energy-Efficient Building Practices
Vietnam energy-efficient building practices have shown that they can scale fast. It’s no longer about a few showcase projects, but a growing trend reshaping the sector. As construction continues to boom across commercial and residential developments, embedding smart, energy-saving technologies into every new project will be key. And, the journey is far from over. However, the path forward is clear. With the right policies, investment, and awareness, Vietnam’s construction sector can lead the region in building a greener, more efficient future, one structure at a time.
