Roadmap for Energy-Efficient Buildings and Construction in the Association of Southeast Asian Nations

Roadmap for Energy-Efficient Buildings and Construction in ASEAN

Abstract

The buildings sector plays a critical role in decarbonizing the global economy. In ASEAN, buildings account for nearly a quarter of the region's total final energy consumption and energy-related CO2 emissions. Without ambitious policy actions, the IEA predicts that both final energy consumption and CO2 emissions in buildings will continue to grow. However, improving energy efficiency in building envelopes and systems, increasing the utilization of renewable energy, phasing out traditional biomass, and transitioning to clean cooking and electricity can significantly reduce CO2 emissions. By 2040, these measures could lead to more than a 60% reduction in CO2 emissions from buildings compared to 2020 levels.

Key Findings

• Energy Consumption and Emissions: Buildings in ASEAN currently account for about 24% of the region's final energy consumption and energy-related CO2 emissions.
• Policy Tools: The Roadmap identifies key energy-efficient and low-carbon actions that governments can implement to drive energy efficiency improvements in the building sector.
• Reduction Potential: Implementing these measures could result in a more than 60% reduction in CO2 emissions from buildings by 2040 compared to 2020 levels.
• Benefits: These actions will also provide numerous benefits to households, society, and governments, including improved energy access for vulnerable households.

Key Actions

• 2025: Implementing energy-efficient building codes, standards, and labeling programs; promoting energy-efficient appliances and lighting; and encouraging the adoption of green buildings.
• 2030: Increasing the share of renewable energy in buildings; promoting district heating systems; and expanding the use of energy-efficient building materials.
• Beyond 2030: Moving towards net-zero carbon buildings through further improvements in energy efficiency and the widespread adoption of renewable energy technologies.

Collaborative Efforts

The Roadmap is part of a collaborative project between the International Energy Agency (IEA), ASEAN Member States (AMS), the ASEAN Secretariat (ASEC), and the ASEAN Centre for Energy (ACE). The project builds on the work of the Global Alliance for Buildings and Construction (GlobalABC) and the United Nations Environment Programme (UNEP).

Conclusion

The Roadmap provides a comprehensive framework for achieving energy-efficient buildings and construction in ASEAN, focusing on reducing energy consumption and CO2 emissions through strategic policy actions. This collaborative effort aims to support sustainable development and improve the overall energy landscape in the region.
