Power Bills Set to Rise Again – How Smart Home Design Can Save You Money

As Australians continue to grapple with the rising cost of living, another financial pressure is set to hit households: increasing electricity bills. The Australian Energy Regulator (AER) has announced that, from July 1, 2025, the Default Market Offer (DMO)—which sets a benchmark price for electricity—will increase by up to 8.9% in some regions around Australia (ABC News, 2025).

For the average homeowner, this means higher energy costs, with annual electricity bills expected to rise to over $2,200 in some states (ABC News, 2025).

Why Are Power Bills Increasing?

✅ Higher Wholesale Energy Costs – Global supply and demand issues drive prices up.
✅ Network Maintenance – The cost of upgrading infrastructure is passed on to consumers.
✅ Environmental Policies – Transitioning to renewable energy can lead to short-term price spikes.

How Can Smart Home Design Reduce Energy Costs?

A well-designed home minimises the need for artificial heating and cooling, reducing power bills. Here’s how:

Our Sherwood Sustainable New Home Project

Case Study: Sherwood Sustainable Home

At dion seminara architecture, we specialise in designing homes that exceed energy efficiency expectations. Our Sherwood Sustainable Home was created to be “off-grid,” producing more energy than it consumes. Key design features of this project included:

✅ Optimised Orientation – Positioning living areas to face north maximises natural light and warmth in winter while reducing heat exposure in summer.
✅ Superior Insulation – High-quality insulation in walls, floors, and ceilings prevents unwanted heat transfer, maintaining stable indoor temperatures.
✅ Strategic Windows & Shading – Double-glazed windows, eaves, and external shading regulate temperatures, cutting down on air conditioning use.
✅ North-Facing Pitched Roofs – Maximising solar panel efficiency for sustainable energy generation.
✅ High-Level Windows & Cross Ventilation – Enhancing natural airflow to keep interiors cooler.
✅ Zoned Ducted Air Conditioning – Efficient cooling for different areas, though rarely needed due to passive design.
✅ Solar & Battery Storage – Selectively positioned and generating more power than used.
✅ Energy-Efficient Appliances & Smart Tech – LED lighting, high energy-star-rated appliances, and smart home systems reduce unnecessary energy consumption.
✅ Aging-in-Place Design – A single-level layout for comfort and accessibility in retirement. power consumption.
