Energy Freedom Starts Here!
Curious about energy efficiency in action? Our cutting-edge Model Home is more than just eco-friendly — it’s a live data experience! Track real-time insights on energy consumption, temperature control, and sustainability metrics. Designed with advanced green technology, the Model Home provides detailed data so you can see the savings and comfort it delivers.
I’ve been keen to see how the home performs during the peak of summer, and now that we have some data, it’s been interesting to analyze the key insights. This summer has been wetter than expected, which has kept daytime temperatures lower while maintaining warmer nights. In passive solar homes, internal temperatures can build up without ventilation on cooler nights, particularly when there is east- and west-facing glass.
The Enervaro monitoring and control system has been performing well. The first chart shows a typical day where the hot water system is programmed to turn on only when solar power is available, reducing reliance on grid or battery energy and minimizing costs.
The second chart covers the month of January, with a noticeable drop in energy use during the second half while we were away. Before that, daily energy demand remained fairly steady between 14 and 18kWh. On average, we used 60% of our daily energy during solar hours—directly from the sun—helping to reduce the need for battery or grid power.
Ater a particularly wet and overcast winter, we’re finally enjoying some warmer weather! With clear blue skies and bright sunshine, our home begins to warm up early in the morning, gradually reaching its peak during the day, and then effectively retaining that heat overnight. Our motto? “Heat up quickly, lose heat slowly!”
The chart below illustrates data from temperature sensors placed throughout the house. It highlights a significant contrast between the outdoor temperature (shown in green) and the temperatures in various rooms inside. On average, the indoor temperature was 20.9°C—over 8°C warmer than the outside!
For this home, there is no connection to the local energy network (‘the grid’). All our electricity comes from an 8.4kW solar array and a Tesla Powerwall 2. This is a relatively small system for an ‘off-grid’ home, which is great because we wanted to test how energy-efficient we can be! Most people don’t want or need to be off-grid, but being energy efficient always makes sense to save money and the environment.

Green Homes Builders are pioneering the delivery of Carbon Free, Energy-Neutral residences, ensuring sustainable living without compromising on comfort or environmental responsibility.
Carbon-free green homes often incorporate energy-efficient technologies and designs to minimise energy consumption and maximise the utilisation of renewable energy. The aim is to achieve a net-zero carbon footprint, meaning that any carbon emissions associated with the home’s operation are balanced by an equivalent amount of carbon removal or offsetting measures, such as carbon sequestration or purchasing carbon credits. Thus, carbon-free green homes contribute to reducing greenhouse gas emissions and combating climate change while promoting sustainable living practices.
Energy neutrality for the Home means that the total amount of energy used by the Home on an annual basis is roughly equal to the amount of renewable energy created on the property. This balance is calculated over the course of one year and may vary based on usage, seasonal changes, and the efficiency of systems installed.
Embracing Carbon-Free, Energy-Neutral home upgrades represents a significant step towards a more sustainable future. By harnessing renewable energy sources, optimising energy efficiency, and prioritising environmentally conscious practices, Green Homes Builders are leading the charge towards a world where comfortable, eco-friendly living is the norm. With these innovative upgrades, homeowners can enjoy the benefits of modern living while making a positive impact on the planet, one home at a time.
