Summary of the Roadmap for Energy-Efficient Buildings and Construction in ASEAN

Core Content

The Roadmap for Energy-Efficient Buildings and Construction in ASEAN outlines a strategic plan to transition the buildings sector in the Association of Southeast Asian Nations (ASEAN) towards net zero-carbon emissions by 2050. It identifies key actions and policy instruments that ASEAN Member States (AMS) can implement by 2025, 2030 and beyond to improve energy efficiency and reduce carbon emissions in both new and existing buildings.

The buildings sector is a major contributor to energy use and emissions in ASEAN, accounting for 23% of total final energy consumption and 23% of energy-related CO₂ emissions in 2020, equivalent to 0.4 gigatonnes of CO₂. Without ambitious policy actions, energy consumption and emissions in the buildings sector are projected to grow by 60% by 2030 and 120% by 2040. The Roadmap emphasizes the importance of energy efficiency improvements, electrification, and the use of renewable energy to reduce emissions by 70% by 2050, with the remaining 30% coming from behavioral changes and on-site renewables.

Main Views and Key Information

Importance of the Buildings Sector

• The buildings sector is central to decarbonizing the global economy.
• Improving energy efficiency and using renewable energy are essential for achieving net zero-carbon buildings.
• The transition to net zero-carbon buildings supports economic growth, energy security, and social well-being.

Need for Policy and Investment

• Policy development and investment are key drivers of progress.
• Current policies and investment levels are insufficient to unlock the full potential of energy-efficient and low-carbon buildings.
• The IEA and ASEAN have collaborated to create a comprehensive policy framework.

Benefits of Transition

• Energy savings and emissions reductions.
• Improved air quality and public health.
• Lower energy bills for households and businesses.
• Enhanced thermal comfort and indoor air quality.
• Job creation in construction and energy management.
• Increased system resilience and security.

Key Recommendations

• Urban Planning: Develop sustainable, compact, and connected cities through integrated planning, policy alignment, and infrastructure improvements.
• New Buildings: Enforce mandatory building energy codes, promote low-carbon and efficient designs, and increase market demand for such buildings.
• Existing Buildings: Retrofit buildings to improve energy performance and reduce embodied carbon, with a focus on quality and scale of retrofits.
• Materials: Use low-embodied-carbon materials, promote material efficiency, and support data collection and carbon disclosure.
• Systems and Operations: Improve appliance and system efficiency, encourage sustainable energy devices, and promote awareness of operational performance.
• Sustainable Energy: Integrate renewable energy into urban planning, support decentralized energy production, and enable grid-interactive buildings.
• Resilience: Incorporate climate resilience into building codes and materials regulations, and enhance data monitoring of disaster risks.

Implementation Strategy

• The Roadmap includes seven action areas, each with a vision, policy options, and actionable steps.
• It is designed to be context-specific, allowing each AMS to tailor its implementation plan based on local priorities and resources.
• The policy package should include regulations, incentives, and information instruments.
• Mandatory building energy codes, product standards, and procurement regulations are highlighted as critical tools.
• Certification and labelling can guide consumers and developers towards sustainable choices.
• Disclosure and benchmarking are necessary for transparency and accountability.
• Training programs and capacity building are essential to support the implementation of the Roadmap.

Conclusion

The Roadmap serves as a guide for ASEAN Member States to develop and implement energy-efficient and low-carbon building policies. It is aligned with the IEA’s Net Zero by 2050 report and supports the ASEAN Plan of Action for Energy Cooperation (APAEC) Phase II. The ultimate goal is to achieve net zero-carbon buildings by 2050, with 2025 and 2030 as key milestones. The Roadmap also emphasizes the need for multi-stakeholder collaboration, strategic planning, and holistic approaches to ensure a successful transition.
