Conrad EnerPHit 2024

House Notes – Conrad EnerPHit

A leaky, cold 1950s weatherboard home has been completed transformed into one of Australia’s most healthy, comfortable and energy efficient buildings we’ve been able to achieve this by applying the voluntary international standard Passivhaus or the less commonly know term EnerPHit (retrofitting existing building to Passivhaus).

There are only a small number of EnerPHit homes in Australia, our dwelling not only defies conventional norms but also presents a captivating narrative of sustainability. Instead of succumbing to the trend of knockdown rebuilds, we embraced a conscientious approach, minimizing waste and embodied energy in the construction process. Our home is a real-life example of the benefits that can be reaped by adopting such a mindset—a true testament to the possibilities that lie beyond traditional ‘renovation’ methods.

Join us as we unveil the unique features and repurposed elements that characterize this exceptional home. Beyond showcasing this recently completed project, our primary goal is to kindle awareness about the transformative power of Passivhaus.

By sharing our journey, we hope to inspire a shift in the way Melbourne and Australia approach construction—a shift that prioritizes the well-being of both inhabitants and the planet. Welcome to a realm where healthy homes contribute to healthy lives and a sustainable future.
