Why a Climate Safe Room Is Essential for Home Comfort and Safety

Home should be a sanctuary where comfort and safety are guaranteed. Yet, many Australian homes fall short due to poor insulation and design, leading to uncomfortable living conditions and high energy bills. Most houses are drafty, damp, and struggle to maintain a stable temperature, requiring substantial energy use to stay comfortable. In fact, about 70% of Australian homes have an energy rating of three stars or lower out of ten, which indicates poor energy efficiency. Newer homes are now mandated to achieve at least seven stars, but many existing dwellings still face challenges.

During winter, more than 80% of homes in Victoria are colder than 18°C—below the World Health Organization's recommended minimum temperature. These conditions highlight the urgent need for practical solutions to improve indoor thermal comfort.

The Concept of a Climate Safe Room

A Climate Safe Room is a strategic space within a home designed to be a refuge during extreme weather events such as heatwaves and cold spells. Instead of upgrading the entire house—an often costly and complex process—focusing on one room can provide immediate relief and reduce energy costs. This approach is rooted in the successful 'cocoon' models tested by local councils like Mildura in 2011, and has been piloted by organizations including Geelong Sustainability and Yarra City Council.

These rooms are especially beneficial for vulnerable residents, including social housing tenants, who face greater difficulties affording extensive home improvements. Designing a Climate Safe Room involves careful measures to ensure it remains thermally controlled, primarily by sealing drafts and improving insulation.

How To Create Your Own Climate Safe Room

The first step is draft-proofing - sealing gaps around windows, doors, and walls to prevent heat from escaping in winter or entering in summer. Low-cost, DIY solutions such as weatherstripping and caulking are effective and easily accessible through online resources.

Effective insulation enhances the climate resilience of a room. Upgrading ceiling insulation and using thermal curtains or blinds on windows can significantly reduce heat transfer. Additional options like secondary glazing and reflective films further improve energy efficiency.

External shading devices like blinds or barriers help control heat gain during summer but should be removed in winter to maximize warmth.

Heating and Cooling Strategies

Once drafts are sealed and insulation improved, installing reverse-cycle air conditioning offers efficient heating and cooling without indoor air pollution. These units work best when the room is properly insulated, preventing heat loss or gain through gaps.

Incorporating outdoor shading and barriers can significantly cut down on unwanted heat transfer during summer, making these spaces even more effective.

Empowering Households to Build Climate Resilience

The University of Melbourne's Retrofit Lab has collaborated with the Energy Efficiency and Electrification Alliance to demonstrate the effectiveness of Climate Safe Rooms. With guiding resources and community engagement, homeowners and renters alike can create their own climate havens, improving comfort while reducing energy costs.
