New Directors Set to Advance Sustainable Housing in Australia

How Future-Proofing Refrigerants Can Transform Australian Housing

Update Refrigerants: A Critical Component for Future-Proofing Buildings In an era where environmental consciousness is at an all-time high, the decisions made about refrigerants in our buildings are pivotal. The Green Building Council of Australia (GBCA) and the Australian Institute of Refrigeration, Air Conditioning and Heating (AIRAH) have emphasized this through a joint discussion paper titled Freeze Frame: Refrigerants as Long-Term Building Infrastructure. They highlight the essential role of refrigerants in minimizing emissions and enhancing building performance, particularly amidst a growing demand for efficient heating, ventilation, and air conditioning (HVAC) systems. Climate Impact of Refrigerants With over 62 million refrigerant-dependent devices currently utilized across Australia, the HVAC industry has seen a marked increase — a surge of 15% in just five years. Experts project that the amount of refrigerant in use could balloon from 55,000 to 80,000 tonnes by 2036. Alarmingly, these refrigerants, if improperly managed, could contribute significantly to greenhouse gas emissions, equivalent to a quarter of Australia's annual emissions. Jorge Chapa, Chief Impact Officer at GBCA, stresses the importance of integrating refrigerant planning into long-term strategies to avoid escalating costs and unnecessary emissions. Collaboration and Transition Strategies GBCA and AIRAH are advocating for a collaborative approach among stakeholders to transition towards lower-impact refrigerants and sustainable practices. This includes designing buildings that minimize refrigerant reliance through passive design, efficient systems, and the adoption of alternatives with lower global warming potentials. Key recommendations include: Reviewing Existing Buildings: Taking stock of current refrigerants and planning staged transitions. Future-Proof Designs: Creating new buildings with reduced reliance on conventional refrigerants. Voluntary Action: Implementing practices like Green Star to foster industry-wide commitment to sustainability. This proactive approach not only addresses immediate regulatory requirements but also positions Australia as a leader in climate action, particularly as the country prepares for COP31 in 2026. Inspirational Commitments to Sustainable Housing Aligning with Australia’s climate goals, the movement toward energy-efficient housing is gaining momentum. Builders and homeowners are encouraged to adopt modular homes or prefabricated housing, which can significantly enhance energy efficiency. These methods reduce waste during construction and promote the use of sustainable materials, further minimizing the carbon footprint associated with traditional construction practices. The Economic Case for Sustainable Decisions While transitioning to more sustainable refrigerants and building practices might initial seem costly, the long-term benefits could outweigh these expenses drastically. Enhanced energy efficiency leads to reduced energy bills and lower maintenance costs, thereby providing financial respite over time. Moreover, properties built with a focus on sustainability often enjoy higher market value, appealing to eco-conscious buyers. Get Involved in Sustainable Building Practices It’s clear that the choices we make today regarding refrigerants and building systems will have lasting implications. Whether you're a homeowner contemplating a new build or a working couple looking to retrofit existing systems with energy-efficient solutions, there are steps you can take. By embracing sustainable housing options and actively participating in initiatives that promote energy-efficient practices, you can contribute to a healthier planet for future generations.
