Project Summary
The Wilam Ngarrang Retrofit project is Australia’s first plus energy retrofit of an apartment building. Providing an innovative example of the environmental, social and financial benefits of retrofitting existing apartment blocks, this project celebrates our existing structures with all their embodied energy and carbon.
With a minimally invasive design, Kennedy Nolan has improved the building’s thermal performance and extended its lifespan. Environmental initiatives prioritised recycling existing material and the use of low carbon materials, resulting in an 82% reduction in construction-based carbon emissions. Energy efficiency has been achieved through passive design choices minimising the need for heating and cooling, while improving ventilation. Reliance on the electrical grid has been reduced with the installation of solar panels, decreasing the building's energy usage by approximately 70%. Other initiatives included rooftop rainwater collection and efficient water fittings to minimise grid water demands.
Prioritising community, the project has improved amenity and connectivity for tenants while also addressing social injustices. The site includes a shared vegetable garden and composting for the building and a communal laundry elevated into a social space. Importantly, tenants will receive an estimated 80% reduction in bills due to energy saving infrastructure. Kennedy Nolan has ensured companies responsible for the building's ongoing care have an ethos to improve environmental, social and/or economic outcomes. Ongoing leasing will be managed by HomeGround Real Estate, an ethical company that invests 100% of its profits to help end homelessness, with two of the apartments being rented at below market rate to help tenants who would otherwise struggle to enter the market. Finally, the building was named Wilam Ngarrang by the Wurundjeri Land Council and is 'Paying the Rent' to First Nations organisations.
