Measuring airflows
Ventilation systems in New Zealand homes rarely have their airflows measured and adjusted during installation, resulting in poorly ventilated rooms. Using active flow hoods during commissioning could change this.

Ventilation systems in New Zealand homes rarely have their airflows measured and adjusted during installation, resulting in poorly ventilated rooms. Using active flow hoods during commissioning could change this.
Sufficient ventilation is crucial as our homes become more airtight. A mix of passive and mechanical options can work well, but all designs should start by getting the source extraction measures right.
BRANZ scientists have firm connections with their international peers, collaborating on joint building science projects and ensuring New Zealand has access to the latest and best information.
Twenty years ago, roofs didn’t need to be specifically ventilated. Today, things are different. That’s because 21st century homes are more airtight, and if they aren’t aired, condensation may form.
With continuing analysis at BRANZ since the article Ventilation and subfloors in Build 149, we’re now able to shine more light on moisture accumulation in subfloor spaces.
Just what do Kiwis do to keep their homes free from stuffy air? BRANZ is using science to find the answers and aid in the design of better ventilation systems.
