1. Statutory Drivers: QCVN 09:2017/BXD, Decree 15/2021/NĐ-CP & The 2029–2030 Labeling Horizon
Vietnam's regulatory transition toward high-performance building envelopes rests on four statutory pillars: QCVN 09:2017/BXD (National Technical Regulation on Energy Efficiency Buildings—mandatory for all new and renovated buildings ≥ 2,500 m²), Decree 15/2021/NĐ-CP (legally codifying Green Buildings and energy-efficient construction in Vietnamese investment law), Decree 09/2021/NĐ-CP on construction material management, and Prime Minister's Decision No. 280/QĐ-TTg.
Following a two-year voluntary incentive phase for building envelope materials (covering windows, doors, walls, and roofs through endorsement and comparative labels), Vietnam's program transitions into mandatory energy labeling leading into 2029–2030 to achieve Decision 280/QĐ-TTg's statutory target that ≥ 50% of insulating building materials are energy-labeled by 2030, alongside requiring 25% of domestic construction materials to be certified green products and 100% compliance of new buildings with QCVN 09:2017/BXD.
2. The 3 Mandatory Physical Parameters: SHGC/U-Factor, Thermal Conductivity (λ) & SRI
Because many domestic Vietnamese producers have not yet published certified thermal values, foreign suppliers who provide MoC-ready laboratory reports capture immediate specification advantage across three categories:
(1) Coated & Low-E Architectural Glass (US$570M+ Vietnam Market): Must certify maximum Solar Heat Gain Coefficient (SHGC) across North, South, and East/West orientations and Overall Heat Transfer Coefficient (U-factor, W/m²·K) per Table 2 of QCVN 09:2017/BXD.
(2) Opaque Wall & Roof Thermal Insulation (PIR/PUR, Mineral Wool, AAC Panels): Must certify Thermal Conductivity (λ — lambda, W/m·K) and minimum Thermal Resistance (R-value, m²·K/W) per Table 4 of QCVN 09:2017/BXD.
(3) Cool Roofing & Exterior Finishes: Must certify Solar Reflectance Index (SRI) to combat tropical solar heat gain.
3. Specifying Materials into FDI Industrial Parks (LEED / LOTUS) & Commercial Towers
Foreign Direct Investment (FDI) manufacturing campuses in Bình Dương, Đồng Nai, Bắc Ninh, and Hải Phòng alongside Grade-A commercial developments in Ho Chi Minh City and Hanoi account for the majority of USGBC LEED, VGBC LOTUS, and BCA Green Mark projects in Vietnam. International building material manufacturers accelerate adoption by preparing localized technical submittals for MEP consultants, facade engineers, and licensed regional importer-stockists early in the design stage.

5. Frequently Asked Questions
Q1. What are the mandatory energy labeling rules for building materials in Vietnam leading up to 2029 and 2030?
Under Prime Minister Decision 280/QĐ-TTg and Ministry of Construction (MoC) roadmaps, Vietnam established comparative and endorsement energy labels for building envelope materials (glazing, windows, wall/roof insulation). After an initial two-year voluntary incentive phase, energy labeling transitions to mandatory enforcement to ensure at least 50% of insulating building materials on the market are energy-labeled by 2030.
Q2. What technical values (SHGC, U-factor, R-value, SRI) are required under Vietnam's building energy code QCVN 09:2017/BXD?
QCVN 09:2017/BXD mandates maximum U-factor and orientation-specific Solar Heat Gain Coefficient (SHGC) limits for fenestration/glazing under Table 2, minimum Thermal Resistance (R-value) and Thermal Conductivity (λ — lambda) limits for opaque walls and roofs under Table 4, and Solar Reflectance Index (SRI) benchmarks for roofing.
Q3. How big is the coated glass and green construction material market in Vietnam?
Vietnam's coated and Low-E architectural glass market alone has reached approximately US$570 million and is expanding rapidly alongside green insulation, AAC blocks, and smart HVAC—driven by 100% mandatory QCVN 09:2017/BXD compliance for buildings ≥2,500 m² and surging LEED/LOTUS certifications across FDI industrial parks.
