How to Improve Energy Performance in Mackay & Whitsundays
Roof and Wall Colour Selection
Light coloured roofs and walls are the most cost-effective solution to improving performance. Contrary to popular belief, wall colour often has a greater impact than roof colour in tropical climates.
External Shading
Wide eaves and verandahs significantly reduce solar heat gain through walls and glazing. Try to limit any exposure to the sun, particularly from the west. External shading is far more effective than internal blinds.
Design for Airflow
Cross-ventilation is key in humid tropical climates, taking advantage of any natural breezes. Ceiling fans can compensate for design. Larger, well-placed ceiling fans significantly improve comfort.
Ceiling Insulation Matters
Ceiling insulation performs significantly better than under-roof insulation as it isolates the living space from the hot roof cavity.
Optimise Glazing
Reduce west-facing glazing where possible, ensure all glazing has adequate shading from eaves and verandahs. Low-E and double-glazed windows perform well, however are expensive and often not required in tropical climates.
Solar PV
Solar PV can offset all of a home’s energy use, while design improvements often only reduce cooling costs.
