What are the most effective strategies for designing and constructing net-zero energy residential dwellings in metropolitan Australian centres?

Achieving net-zero energy in metropolitan Australian dwellings prioritises passive design, optimising orientation for solar gain and natural ventilation. High-performance building envelopes, utilising superior insulation and double-glazed windows, minimise heat transfer. Efficient electric appliances and heating/cooling systems, coupled with a robust rooftop solar PV array, are crucial for onsite energy generation. Integrating smart home energy management systems further reduces consumption. Water-sensitive urban design elements, such as rainwater harvesting and greywater recycling, contribute to overall sustainability, reducing embodied energy and operational costs for homeowners.
