Key Takeaways
- vPanel carries Singapore Green Label: Vodapruf vPanel ALC panels are certified under the Singapore Green Label scheme — recognised in Malaysian GreenRE and GBI assessments.
- Superior thermal conductivity: At 0.125 W/mK, vPanel reduces building heat load — contributing directly to energy efficiency credits in GBI and GreenRE assessments.
- 10× lower manufacturing energy: Vodapruf’s non-autoclaved production uses 10× less energy than conventional AAC panel manufacturing, supporting embodied carbon reduction goals.
- Lightweight reduces structural load: Lighter walls reduce foundation and column sizes, saving material and reducing embodied carbon across the entire structure.
- No plastering = less material waste: vPanel’s skim-coat-ready surface eliminates the plastering layer, cutting cement consumption and site waste.
Green building certification is moving from ‘nice to have’ to ‘mandatory’ for commercial and industrial developments in Malaysia. Developers targeting GBI (Green Building Index) or GreenRE ratings are under increasing pressure to specify materials that earn certification credits.
Wall panels are one of the highest-impact choices a developer can make. They cover the largest surface area of any building element — and their thermal performance, embodied carbon, and material certifications directly affect your green rating score.
In this guide, we break down how ALC panels — specifically Vodapruf vPanel — contribute to green building certification in Malaysia, and what credit categories they support.
What Is the Green Building Index (GBI) in Malaysia?
The Green Building Index (GBI) is Malaysia’s national green rating tool for buildings, managed by the Malaysian Institute of Architects (PAM) and the Association of Consulting Engineers Malaysia (ACEM). GBI rates buildings across six categories: Energy Efficiency, Indoor Environment Quality, Sustainable Site Planning, Material & Resources, Water Efficiency, and Innovation. Wall materials affect at least three of these categories.
GBI has 4 rating levels: Certified, Silver, Gold, and Platinum. Most commercial developers in Malaysia now target at least Silver or Gold. Here is how wall panel selection affects your GBI score:
| GBI Category | How Wall Panel Choice Matters |
| Energy Efficiency (EE) | Lower thermal conductivity → lower OTTV → higher EE score |
| Material & Resources (MR) | Green-certified materials, recycled content, waste reduction |
| Indoor Environment Quality (IEQ) | Thermal comfort from insulating walls |
| Innovation (IN) | Innovative construction methods (e.g. panelised systems) |
How Does vPanel’s Thermal Performance Support GBI Energy Credits?
vPanel’s thermal conductivity of 0.125 W/mK is significantly lower than red brick (0.72 W/mK) and conventional concrete (1.44 W/mK). Lower thermal conductivity means less heat transfer through the wall — reducing the building’s Overall Thermal Transfer Value (OTTV). A lower OTTV directly improves your GBI Energy Efficiency (EE) score. For buildings targeting GBI Gold or Platinum, optimising OTTV is one of the most impactful levers.
| Wall Material | Thermal Conductivity (W/mK) | Relative Heat Transfer |
| Red Brick (clay) | 0.72 | 5.8× more heat than vPanel |
| Standard AAC Block | 0.14–0.24 | 1.1–1.9× more heat than vPanel |
| Hollow Core Concrete Panel | 0.35–0.50 | 2.8–4.0× more heat |
| Vodapruf vPanel (ALC) | 0.125 | Best — baseline for comparison |
In practical terms, using vPanel instead of red brick on a typical 10,000 m² building envelope can reduce OTTV by 15–25%, depending on glazing ratio and orientation. This is a meaningful contribution to GBI Energy Efficiency credits without any change to building design.
What Green Certifications Does Vodapruf vPanel Carry?
Vodapruf vPanel carries the Singapore Green Label — one of the most widely recognised product environmental certifications in Southeast Asia. The Green Label certifies that vPanel has been independently assessed for environmental performance across its lifecycle, including raw materials, manufacturing emissions, and product durability. This certification is directly recognised in Singapore’s Green Mark and can be submitted as supporting evidence in Malaysian GBI and GreenRE assessments.
| Certification | Issued By | Relevance to Malaysian Green Building |
| Singapore Green Label | Singapore Environment Council (SEC) | Accepted in GBI Material & Resources credit; GreenRE evidence |
| SGBC Certificate (LIGHTHERM) | Singapore Green Building Council | Applies to LIGHTHERM products in same project |
| Class A1 Fire (EN 13501-1) | Third-party lab | Safety certification — supports occupant safety credits |
| Green Mark compliance | BCA Singapore | Reference for GreenRE-equivalent performance |
How Does vPanel’s Manufacturing Process Reduce Embodied Carbon?
Vodapruf vPanel is produced without autoclaving — Vodapruf’s proprietary formulation allows the panels to cure naturally over 7 days at ambient temperature. This uses approximately 10× less energy than conventional autoclaved AAC panels, which require 180–200°C pressurised steam for 8–12 hours. Lower manufacturing energy means lower embodied carbon — a key factor in GBI Material & Resources credits and increasingly in lifecycle carbon assessments.
The embodied carbon difference between autoclaved and non-autoclaved panels is substantial:
- Autoclaved AAC panel: Requires industrial autoclave chambers, high-pressure steam, and significant electricity — all contributing to manufacturing carbon.
- Vodapruf vPanel (non-autoclaved): Cured naturally over 7 days in ambient conditions — no autoclave, no pressurised steam. Factory energy consumption is dramatically lower.
- Reduced transport carbon: vPanel’s lightweight design means more panels per truck — 518.4 m² per 40ft lorry. Fewer deliveries = lower transport emissions.
What Other Environmental Advantages Does vPanel Offer?
Beyond thermal performance and manufacturing, vPanel offers three additional environmental advantages: no plastering requirement (eliminating cement render layer and associated material waste), faster installation reducing on-site energy consumption from equipment, and longer service life from its closed-cell water-resistant structure (fewer replacements over the building lifecycle).
- No plastering eliminates waste: Conventional wall systems require render coat + plaster + paint. vPanel eliminates the render/plaster step — reducing cement consumption by one full layer across the entire building.
- Faster build = less site energy: Shorter installation time means less on-site equipment operation — cranes, mixers, scaffolding, lighting — all consuming energy over the construction period.
- Longer service life: vPanel’s closed-cell structure resists moisture absorption — reducing the risk of long-term wall damage, mould, or structural deterioration that requires replacement.
How Does vPanel Compare to Other Green Wall Materials?
Among common green building wall materials in Malaysia — red brick, AAC block, lightweight concrete panel, and ALC panel — Vodapruf vPanel ALC offers the best combination of low thermal conductivity, Green Label certification, non-autoclaved manufacturing, and direct skim coat finish. No single competing product combines all four of these green attributes in one system.
| Green Attribute | Red Brick | AAC Block | Conventional ALC Panel | Vodapruf vPanel |
| Thermal Conductivity | 0.72 W/mK (poor) | 0.10–0.24 W/mK | ~0.15–0.20 W/mK | 0.125 W/mK ✅ |
| Green Certification | None | Varies | Varies | Green Label ✅ |
| Non-autoclaved | N/A | No (autoclaved) | No (autoclaved) | Yes ✅ 10× less energy |
| No plastering required | No | No | Some | Yes ✅ |
| Low water absorption | No | No (up to 20%) | Moderate | Yes ✅ (closed-cell) |

Frequently Asked Questions (FAQ)
Does vPanel qualify for GBI Material & Resources credits in Malaysia?
Yes. Vodapruf vPanel carries the Singapore Green Label, which can be submitted as supporting evidence for Material & Resources credits in GBI assessments. Additionally, vPanel’s non-autoclaved manufacturing and lighter weight (reducing structural material needed) contribute to lower embodied carbon — an emerging GBI and GreenRE consideration.
What is Malaysia’s OTTV requirement for commercial buildings?
Malaysia’s Building Energy Efficiency standard (MS1525) sets OTTV limits of 50 W/m² for office buildings and similar commercial developments. Using vPanel instead of red brick can reduce OTTV by 15–25% on a typical building, helping projects meet or exceed this requirement and earn GBI Energy Efficiency credits.
Is vPanel certified under GreenRE?
vPanel’s Singapore Green Label is accepted as supporting evidence in GreenRE Material & Resources assessments. For GreenRE-specific documentation, our team can provide product certificates, thermal conductivity test reports, and manufacturer declarations.
How does non-autoclaved manufacturing affect embodied carbon?
Autoclaving requires 180–200°C pressurised steam for 8–12 hours per batch, consuming significant electricity and fuel. Vodapruf’s natural curing process eliminates this step, using approximately 10× less manufacturing energy. In embodied carbon calculations, this can meaningfully reduce the cradle-to-gate carbon of the wall system.
Can vPanel be used for external walls in Malaysian green buildings?
Yes. vPanel’s low thermal conductivity (0.125 W/mK) and closed-cell water-resistant structure make it suitable for both internal partitions and external wall applications. For external walls, a waterproofing render coat is applied before the skim coat finish. The thermal performance of the external wall directly affects OTTV and GBI EE scores.
What thickness of vPanel is recommended for Malaysian green building external walls?
For external walls targeting GBI or GreenRE energy credits, 150mm vPanel is typically recommended. A 150mm vPanel achieves thermal resistance (R-value) of approximately 1.2 m²K/W — significantly higher than a 230mm red brick wall. Actual recommendations depend on building geometry, glazing ratio, and orientation.
Does vPanel’s Green Label certification expire?
Green Label certificates require renewal every 3 years following reassessment. Vodapruf maintains its Green Label certification and keeps it current. For active project submissions, we can provide current valid certificates upon request.
