ASIATODAY.ID, JAKARTA — The ASEAN Centre for Energy (ACE), Global Green Growth Institute (GGGI), and HEAT International, through the Asia Low-Carbon Buildings Transition (ALCBT) Project, in collaboration with ASHRAE Indonesia Chapter, with support from the International Climate Initiative (IKI), continue to accelerate the transition to low-carbon buildings in Southeast Asia and Indonesia through energy efficiency measures and collaboration with the Government of Indonesia.
The building sector in Indonesia currently contributes 33% of greenhouse gas emissions, with cooling use as the main contributor. At a series of dialogues held during Refrigeration & HVAC Indonesia Expo 2025 at the Jakarta International Expo on September 24th —26th , the Ministry of Public Works of Indonesia shared the government’s commitment to meeting resource efficiency performance targets in buildings operated by both the government and the private sector.
“The building sector is one of Indonesia’s largest contributors to emissions. This has become a serious concern for the Government in encouraging various stakeholders to support emission reduction. To accelerate emission reduction efforts, the Government is promoting stakeholder engagement through capacity-building programs and by assisting local governments in the implementation and certification of green buildings,” said Ir. Diana Kusumastuti, M.T., Vice Minister of Public Works.
Co-hosted by the Ministry of Energy and Mineral Resources (MEMR) and the Ministry of Public Works (MPW), the event brought together 300 participants comprised of key stakeholders in the building sector, including government, building owners, financing institutions, and heating, ventilation, and air conditioning (HVAC) producers, to discuss Indonesia’s efforts and progress towards a sustainable and low-carbon building future.
Prof. Dr. Eng. Eniya Listiani Dewi, Director General of NREEC at the Ministry of Energy and Mineral Resources, highlighted energy efficiency as a strategic and cost-effective measure to accelerate the energy transition and support Indonesia’s Net Zero Emission target.
“Energy efficiency can contribute to reducing up to 37% of national emissions while delivering direct benefits to households through lower electricity bills and smarter technologies,” she stated.
She further emphasized the role of Green Public Procurement (GPP) in advancing the adoption of energy-efficient air conditioners in Indonesia.
“By embedding efficiency criteria into procurement policies and ensuring efficient products are available in the national e-catalogue, we are not only sending a strong signal to the market but also helping households gain easier access to green technologies,” she added.
Energy consumption in the buildings sector in ASEAN and Indonesia is mainly driven by the use of air conditioners due to the tropical climate and humidity levels. At the event, ACE introduced the Green Public Procurement Guidelines for energy-efficient air conditioners to strengthen market demand for efficient cooling solutions in Indonesia.
ACE Executive Director Dato’ Ir. Ts. Razib Dawood said, “Green Public Procurement is a powerful tool for Southeast Asia’s low-carbon transition. By embedding efficiency into purchasing decisions—particularly for air conditioning, which accounts or the largest share of building energy use—governments can lead by example. This approach not only cuts emissions but also signals the market to innovate, encouraging producers and suppliers across the region to prioritize efficiency and sustainability in their products.”
The ALCBT project aims to use the momentum from these dialogues to formulate key policy recommendations for the Government of Indonesia.
“From assessing the best available cooling technology to identifying enabling policies, these efforts are targeted at bolstering energy efficiency in the building sector through innovative approaches to drive down emissions,” said Rowan Fraser, GGGI Country Representative for Indonesia.
Equally important was integrating life-cycle carbon assessment tools into decision-making. Through capacity-building sessions on the Building Emissions Assessment Tool (BEAT) and training on natural refrigerants led by HEAT International, the programme aimed to raise awareness and build technical capacity among stakeholders to measure, manage, and reduce emissions across the building life cycle.
Moving forward, ACE and ALCBT Consortium Partners remain committed to supporting Indonesia and ASEAN in their transition toward a sustainable built environment, ultimately achieving climate and sustainable development goals. (AT Network)
