Whole house ventilation systems are increasingly being promoted as the solution to house
performance problems such as dampness and cold. However, they’re also a very expensive item to install and you will want to be certain they will make a difference.

If you want a true energy recovery ventilator for your home, a balanced system with a real heat exchanger is the only way to truly recover energy which is usually wasted, to warm or cool your home.
This is no more evident than in the findings of a comprehensive Otago University Report commissioned for EECA (Energy Efficiency and Conservation Authority), researching the heating and cooling potential of ventilation systems.

The New Zealand Building Code requires homes to ventilate using outdoor air to maintain air purity. Ventilation systems that draw air from the roof space and not directly from outside do not comply with ventilation standard NZS4303:1990 "Ventilation for acceptable indoor air quality". They cannot be used to comply with the Building Code Acceptable Solution for ventilation.
