Combating internal moisture
Newer homes may be less draughty but concern is growing that they are accumulating too much internal moisture. Ventilation is key, and BRANZ is researching how to keep homes aired, warm and healthy.

House condition matters
By Vicki White – 1 October 2016, Build 156, Feature article
Early results from the latest House Condition Survey indicate the continued presence of mould in over half the properties. This is bad news, as evidence links mould and damp houses with poor health and social wellbeing.
Airtightness trends
By Stephan Rupp, Stephen McNeil – 1 June 2018, Build 166
BRANZ is researching the airtightness of new homes as part of its ‘warmer, drier and healthier buildings’ programme. This, the first of three articles, discusses airtightness and infiltration and dispels some common myths.
Optimal ventilation?
By Aidan Bennett-Reilly, Dr Manfred Plagmann – 1 October 2020, Build 180, Feature article
Conventional ventilation keeps a home sufficiently aired but has an energy cost. An option is to install a mechanical ventilation heat recovery system that ventilates a home while efficiently conserving energy.
A breath of fresh air
By Dr Manfred Plagmann – 1 February 2016, Build 152, Feature article
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.
Ventilation and subfloors
By Stephen McNeil – 1 August 2015, Build 149
Subfloor performance plays a big part in the comfort and health of our homes. BRANZ is modelling appropriate levels of subfloor ventilation to understand what makes a healthy building.
Warmer, drier, healthier buildings
By Mark Jones – 1 December 2018, Build 169, Feature article
BRANZ’S Warmer, drier, healthier buildings programme is making progress on understanding how living environments affect our health. Collaborative research is delivering notable outcomes, and this looks set to continue.
Airtightness trends (part 2)
By Stephen McNeil – 1 August 2018, Build 167
In the last Build, we looked at airtightness, how to measure it and the positives and negatives of being leaky or airtight. Now we consider how controlled infiltration makes ventilation design easier and the resulting savings.
BRANZ’s collaborative science
By Dr Manfred Plagmann – 1 June 2020, Build 178, Feature article
BRANZ scientists work collaboratively and in multi-disciplinary teams to effectively find answers to some of the complex issues that buildings present, particularly as the push to higher-performing buildings grows.
Agents of change
By Nigel Isaacs – 1 June 2014, Build 142, Feature article
New Zealanders are a resourceful lot, always exploring new and better ways of doing things. We look back in time at two distinctly Kiwi twists on ways of building.
