Session 02 of the Bangladesh Innovation Summit 2026 focused on the growing importance of green and sustainable building practices in Bangladesh, particularly as the building sector contributes roughly one-third of global carbon emissions. Discussions examined why green building adoption, despite early momentum in the RMG sector following the Rana Plaza disaster and increased use of LEED certification, has remained limited in other sectors, with perceived costs of green construction and certification identified as a key barrier.

The session also highlighted low-carbon and blended cement, emphasizing the need to reduce clinker — the major source of cement-related emissions — and discussed paints and coatings as practical measures for improving building resilience and reducing heat exposure. Participants further explored the potential benefits of developing a Bangladesh-specific green building rating system rather than relying primarily on international frameworks such as LEED.

Finally, the session emphasized the government's role in accelerating adoption through policy, incentives, and supportive frameworks, including the newly developed DA-SH sustainable building assessment framework, to make sustainable construction more accessible, affordable, and contextually appropriate for Bangladesh.

Dr. Md. Ashikur Rahman Joarder: highlighted the absence of clear and standardized green building criteria outside the RMG sector, noting that LEED certification does not assess building safety, and that the emphasis on certification among RMG factories may sometimes overshadow actual energy efficiency; he also pointed to the lack of a Bangladesh-specific system for monitoring real building performance, including energy, gas and water consumption.

Dr. Kanthasat Boontem: pointed to Bangladesh's reliance on imported clinker — the major carbon-emitting component of cement — as a significant challenge to reducing the construction sector's carbon footprint. The persistent perception that green buildings and low-carbon materials are considerably more expensive continues to discourage homeowners and developers from adopting them.

Dr. ASM Obaidullah Mahmud: identified the limited availability of local, independent testing and verification of manufacturers' environmental claims — particularly for products such as cooling paints — as a barrier to credibility and informed adoption.

• 1. A research-based local rating system such as DA-SH, introduced to complement or substitute LEED and better reflect local conditions.
• 2. Lower-carbon and blended cement products with reduced clinker content, offering a substitution path to cut emissions directly.
• 3. Cool/heat-reflecting paints and coatings using hollow-fibre, heat-reflecting pigments that can lower surface temperature by roughly 3°C and partially absorb pollutant gases.
• 4. A proposed three-stage building rating process: at design stage, immediately after construction, and based on ongoing performance (utility bills) after occupancy.
• 5. Using carbon dioxide equivalence as a common unit to measure and compare the impact of energy, water, and material choices, working toward net-zero emission buildings.
• 6. Government incentives such as extra floor space, and lower holding tax, electricity, and water bills for certified green buildings.
• 7. Closer collaboration between academia, industry R&D, and government procurement policy to scale up low-carbon materials.

• 1. Bangladesh has 90+ LEED-certified RMG (garment) factories, following the Rana Plaza collapse.
• 2. A cement/paint company's newly built roughly 55,000 sq. ft. R&D facility in Bangladesh, designed to minimize electrical equipment use by relying on daylight.
• 3. The company's cool-coating technology, tested and verified by BUET (Bangladesh University of Engineering and Technology), showed about 43–45% effectiveness after roughly 3 years.
• 4. CSR/funding support extended to an innovation project at Chittagong University.
• 5. Regional comparison: Vietnam has the lowest clinker factor in the company's group and is a net exporter of clinker; Sri Lanka's coastal soil conditions were compared with Bangladesh's.
• 6. A comparison to the historic shift from CFL to LED/energy-saving bulbs, as an example of successful consumer advocacy despite higher upfront cost.

• 1. Develop and strengthen a Bangladesh-specific, performance-based national green building rating system rather than relying solely on international systems.
• 2. Base building ratings on actual monitored performance (utility bills, emissions) at multiple stages — design, post-construction, and occupancy — not design specifications alone.
• 3. Continue substituting high-clinker cement with lower-carbon/blended alternatives, supported by clearer procurement standards and specifications.
• 4. Government to lead by example through green demonstration projects in public housing and buildings.
• 5. Expand public incentives (floor-space bonuses, reduced holding tax and utility charges) to encourage private adoption.
• 6. Strengthen collaboration between universities, industry R&D, and government/regulators, with universities training talent and industry investing in commercialisation.
• 7. Continue public awareness efforts to shift the perception that green building is inherently more expensive, emphasizing long-term (4–5 year) payback.

• 1. Ministry of Housing and Public Works to continue rolling out the sustainable building assessment framework developed with UNEP and UNOPS.
• 2. Government considering new incentive policies: extra floor space for green buildings, and reduced holding tax, electricity, and water bills.
• 3. Company to continue R&D partnerships and CSR-linked funding with universities, including Chittagong University.
• 4. Call for universities to strengthen technical training, and for industry to keep investing in R&D and commercialisation of lower-carbon materials.
• 5. Discussion intended to feed into practical recommendations on regulatory incentives, industry-academia collaboration, green finance, and demonstration projects.

• 1. Historical framing: the earliest known building codes are traced to Hammurabi's laws (roughly 270 laws, including several on construction and builder liability for collapse).
• 2. LEED, while widely used in Bangladesh's RMG sector, was never designed as a safety-measurement standard in the first place.
• 3. The panel included a research/policy view (academia), an industry/manufacturing view (cement and paints), and a government/regulatory view (Ministry of Housing and Public Works).

1. 1. Green building is no longer a niche environmental concern — with buildings responsible for roughly a third of global emissions, it is central to housing, economic resilience, and quality of life in Bangladesh.
2. 2. Cost is the biggest perception barrier to green building adoption, but lower-carbon materials and efficient design typically pay back within 4–5 years and are cheapest when built in from the design stage.
3. 3. A credible, Bangladesh-specific rating system must be performance-based, monitoring actual energy, water, and material use across design, construction, and occupancy, rather than a one-time, design-stage certification.

Government should lead by demonstration, piloting green building standards in public housing and buildings, backed by procurement policy, incentives (floor-space bonuses, reduced holding tax/utility charges), and closer academia-industry R&D collaboration.
