Not to exceed 15kWh annually OR 10W (peak demand) per square metre of usable living space.

Space Cooling Demand

Roughly matches the heat demand with an additional, climate-dependent allowance for dehumidification.

Primary Energy Demand

Not to exceed 120kWh annually for all domestic applications (heating, cooling, hot water and domestic electricity) per square meter of usable living space.


maximum of 0.6 air changes per hour at 50 Pascals pressure (as verified with an onsite pressure test in both pressurised and depressurised states)

Thermal Comfort

Thermal comfort must be met for all living areas year-round with not more than 10% of the hours in any given year over 25°C*
