Thailands Green Building Certification Standards

As sustainability becomes increasingly important globally, Thailand is strengthening its commitment to green building standards. Driven by the need to reduce environmental impact, increase energy efficiency, and provide healthier spaces, Thailand’s green building sector is rapidly evolving. Currently, Thailand’s green building initiatives are guided primarily by two certification standards: LEED (Leadership in Energy and Environmental Design) and TREES (Thailand’s Rating of Energy and Environmental Sustainability). This article explores these standards, Thailand’s progress, and the opportunities and challenges that lie ahead in the green building landscape for 2024.

Key Green Building Certifications in Thailand

1. TREES (Thailand’s Rating of Energy and Environmental Sustainability)

TREES is Thailand’s own green building certification standard, created by the Thai Green Building Institute (TGBI). Established in 2012, TREES has been tailored to suit Thailand’s unique climate and cultural context, covering various aspects of sustainability specific to the Thai environment. It focuses on local requirements, including tropical building designs that consider energy efficiency, air quality, and environmental impact in a warm climate.

• Certification Categories: TREES offers certification under different categories, including TREES-NC (New Construction), TREES-CS (Core and Shell), and TREES-EB (Existing Building). This allows both new and existing buildings to pursue green standards.
• Certification Levels: Buildings can achieve different levels of TREES certification—Certified, Silver, Gold, and Platinum—based on the number of points accumulated across various criteria.
• Key Areas of Assessment: The TREES assessment covers areas such as building management, water conservation, energy efficiency, indoor environmental quality, and materials. Specific to Thailand, TREES also considers parking space availability, recognizing the local reliance on private transportation over public transit​ [Source]

2. LEED (Leadership in Energy and Environmental Design)

LEED is an internationally recognized green building certification system developed by the U.S. Green Building Council (USGBC). LEED is popular among multinational corporations and luxury commercial developers in Thailand due to its global recognition and strict standards.

• Certification Levels: LEED offers four levels of certification—Certified, Silver, Gold, and Platinum—based on points achieved across various categories, such as sustainable sites, water efficiency, and energy use.
  
• Popularity in Commercial Projects: In Thailand, LEED certification is widely used in commercial and office buildings to attract multinational tenants and corporate entities that value sustainability as part of their brand and operations. Notable LEED-certified buildings in Thailand include the Park Ventures Ecoplex and The PARQ in Bangkok, which have achieved LEED Gold and Platinum certifications, respectively​ [Source]

Government Initiatives and Regulations

In recent years, Thailand’s government has introduced several policies to promote green building practices:

1. Energy Conservation Promotion Act: Thailand’s Energy Conservation Promotion Act was initially passed in 1992 and has been updated to include minimum energy standards for buildings over 2,000 square meters or those with high energy consumption. Under this act, buildings must meet criteria in areas such as lighting, air conditioning, and overall energy performance. Though enforcement remains a challenge, the law serves as an essential framework for encouraging energy efficiency.
   
2. Building Energy Code (BEC): Enforced by the Ministry of Energy, the BEC mandates specific energy-saving measures for commercial buildings and new constructions that exceed certain size thresholds. Although compliance with the BEC is voluntary for now, its adoption is expanding, and there is speculation about future mandatory standards.
   
3. Incentives for Green Buildings: To encourage the adoption of green buildings, Thailand offers tax incentives and subsidies. The Department of Alternative Energy Development and Efficiency (DEDE) provides up to 20% of the investment cost in energy-saving upgrades for projects that meet certain criteria, significantly reducing the financial burden of sustainable investments​ [Source]

Key Drivers of Green Building in Thailand

The surge in green buildings across Thailand is driven by multiple factors, including environmental, economic, and social benefits.

1. Cost Savings and Operational Efficiency: Green buildings reduce energy consumption, leading to long-term savings. Research indicates that energy-efficient buildings can achieve a 20-30% reduction in energy costs over five years, providing an attractive return on investment. For example, The PARQ, a LEED-certified project, reduced energy costs by around 30%, showcasing the economic feasibility of sustainable construction​ [Source]
   
2. Higher Rental Income: Green-certified commercial spaces in Bangkok, such as Park Ventures, often command a premium rental rate. Tenants are willing to pay higher rents, as green buildings enhance corporate image and provide healthier environments. In Bangkok, green buildings charge 15-20% higher rents than standard office buildings, appealing particularly to multinational tenants [Source].
   
3. Enhanced Corporate Image and Brand Value: Corporations increasingly recognize the importance of aligning with sustainability goals to appeal to eco-conscious stakeholders. Companies like Toyota have invested in TREES-certified facilities to align with global sustainability goals and project an eco-friendly brand image, setting an example for other multinational corporations in Thailand​ [Source]

Challenges Facing Thailand’s Green Building Sector

Despite progress, Thailand’s green building sector faces several challenges:

1. High Construction Costs: Green buildings often require specialized materials and technologies, making them more expensive than traditional buildings. For example, constructing a LEED-certified building in Thailand can cost 3-10% more than a conventional building, while retrofitting can raise costs by up to 30%. This cost factor has limited the adoption of green standards, particularly in residential buildings​ [Source]
   
2. Lack of Skilled Professionals: The sector lacks sufficient architects, engineers, and contractors with expertise in green building design and construction. As a result, the quality of green building projects may vary, affecting overall energy efficiency and environmental impact. This skill gap is a significant hurdle for expanding green building practices nationwide.
   
3. Limited Awareness and Demand: While awareness is growing, many Thai consumers and smaller developers are still unfamiliar with the benefits of green buildings. This lack of demand in residential markets limits the expansion of green building practices outside the commercial sector, where large corporations are driving growth.
   
4. Inconsistent Enforcement: Although the government has introduced regulations, enforcement is inconsistent, particularly in smaller cities and rural areas. More rigorous enforcement of standards like the BEC and incentives for small developers could improve green building adoption across all regions of Thailand​ [Source]

Future Outlook and Opportunities

The outlook for green building in Thailand is optimistic, with new trends and potential regulations emerging:

1. Expansion Beyond Commercial to Residential: While green certification is currently dominated by commercial properties, there is a gradual shift toward sustainable residential buildings. With rising awareness and potential cost reductions in green technology, developers are beginning to see the value of eco-friendly residential projects, especially in Bangkok and Chiang Mai.
   
2. New Green Standards: Thailand is exploring the adoption of additional standards such as DGNB (German Sustainable Building Council) certification, tailored for the Southeast Asian climate, and Thailand Energy & Environmental Assessment Method (TEEAM), developed in collaboration with Chulalongkorn University. These standards may become widely adopted alongside TREES and LEED as demand for green certifications grows ​[Source].
   
3. Potential Mandates on Green Construction: As part of the country’s commitment to achieving environmental goals, Thailand is considering making certain green building standards mandatory. The Ministry of Energy is evaluating stricter requirements for energy efficiency in new buildings, a move that could accelerate the growth of the green building sector significantly over the next few years​ [Source]
   
4. Integration of Smart Technologies: The green building sector is increasingly embracing smart technologies like IoT sensors and AI-driven building management systems. These technologies enhance energy efficiency, optimize resource use, and reduce operational costs, making green buildings more attractive and cost-effective in the long term.

Conclusion

Thailand’s green building sector is progressing steadily, thanks to government policies, private sector interest, and local certification standards like TREES. As the country continues to invest in sustainability, green building certifications are expected to become more widespread, catering to a growing demand from environmentally conscious corporations and investors. However, challenges remain, particularly in high construction costs and limited awareness among small developers.

As Thailand moves towards more sustainable practices, the emphasis on green building will play a crucial role in shaping the future of the country’s real estate market, offering promising opportunities for investors and developers willing to align with eco-friendly initiatives.
