Ventilation

Ventilation is the most important element in your "healthy home, healthy living strategy. If you are experiencing condensation or mold growth anywhere in your home it is directly related to your environment being stale and polluted with bad air.  If your home was full of clean air then these problems would not exist and you would not be reading this. Because you are considering a ventilation system then think about it carefully and make sure it complies with fresh air standards and heat recovery otherwise you will be wasting heat, energy and your money.

Don't be fooled, don't let anyone tell you that dry air is healthy air.   

Only clean air is healthy air, and can only come directly from outside as required  under NZ Standard 4303 "Ventilation for Acceptable Indoor Air Quality" it is not recommended to be sourced from your roof space.

Ventilation of homes is of coarse essential for the replacement of stale, polluted indoor air with fresh outside air and for the removal of moisture generated in the home. Combining a heat recovery ventilation system with high levels of insulation and heating completely changes the indoor environment to an extremely healthy environment. Traditionally New Zealand homes were ventilated by natural ventilation, i.e. infiltration through open doors and windows, which can be characterized as ventilation by coincidence but often does not provide adequate air change to provide a healthy indoor environment.
