Ventilation Update in New Zealand G4 Building Code Compliance 2019
New Zealand have recently introduced legislation that ensures all property landlords have to bring their rental properties to comply with the new government regulations. Building Code clause G4 Ventilation requires that spaces within buildings have adequate ventilation for their intended use and occupancy, have adequate fresh air, and have means to remove moisture, products of combustion (such as cooking fumes, moisture, or gases) and other airborne contaminants.
What is the new ventilation standard?
From 1st July 2019, all habitable rooms in a rental property must have at least one window, door or skylight which opens to the outside and can be fixed in the open position.
In each room, the size of the openable windows, doors and skylights together must be at least 5% of the floor area of that room. Each window door, window or skylight must be openable and must be able to remain fixed in an open position.
All bathrooms and kitchens must have an extractor fan ducted to the outside to ensure healthy homes standards.
IXL Home offers a variety of ventilation ranges which are compliant with the healthy homes standard.
IXL’s signature Tastic Luminate range, along with the new Tastic Ovation, Tastic Classic and Ventflo maintain acceptable levels of airflow over duct runs to effectively remove excess steam and condensation. This would avoid mould growth and damp spots, negative impact on occupants’ health and wellbeing, and long term structural damage or corrosion.
IXL has been a trusted brand in Australian and New Zealand home heating for over 160 years and proudly designs and manufactures the Tastic range locally. They come with a 5-year in-home warranty, and a 2-year warranty on heat lamps and in-line exhaust for peace of mind.
