Thermal modelling uses physics-based software to simulate how heat flows through your building. It helps us predict and optimize indoor temperatures, ensuring your home is comfortable, energy-efficient, and healthy year-round.

The earlier, the better! Engaging us during the preliminary design phase allows us to optimize things like solar orientation, window placement, and insulation before the plans are finalized, saving you from costly design changes later.

To begin a thermal model, we typically need your architectural plans (floor plans, elevations, sections), details on proposed building materials, and the specific site location.

Yes. Thermal modelling calculates solar heat gain and internal temperature fluctuations during peak summer months. It identifies overheating risks and tests mitigation strategies—such as low-E glass, external louvres, or natural cross-ventilation—to ensure comfortable year-round indoortemperatures.

Thermal modelling identifies where building dollars deliver the highest thermal performance return.By calculating exact heat loss profiles, it prevents costly over-specifying of high-end materials where they aren’t needed while targeting insulation and HVAC investments for maximum savings.

Thermal modelling focuses purely on heat flow, solar gain, and energy performance to optimize your building envelope. Passive House is considered international best practise for design the healthiest ultra-low-energy homes. Homestar is a holistic New Zealand rating tool that assesses health, waste, water, and site sustainability alongside thermal performance.

Thermal modelling calculates heat flow, surface temperatures, and thermal bridges (uninsulated structural junctions) across the building envelope. By identifying cold spots before construction, we can optimize insulation and ventilation to prevent internal surface condensation, eliminating the conditions required for mould growth.

While initial construction costs for a certified Passive House can be 5% to 15% higher due to high-performance windows, airtight membranes, and balanced mechanical ventilation (MVHR), running costs for space heating are reduced by up to 90%. Over the building’s lifecycle, lower energy bills and reduced maintenance offset the upfront investment.

It depends on the complexity of your project. A thermal modelling report for a simple single level standalone home starts at $2,250 +gst. Get in touch with us if you would like specific pricing for your project.
