 Programme Overview

Programme Overview

The WAVE (Weathertightness, Air Quality and Ventilation Engineering) programme is a 6-year programme that began in October 2009. The work is jointly funded by the Building Research Levy and the Ministry of Science and Innovation.

WAVE is developing practical solutions to problems that currently plague New Zealand homes such as leaky buildings and indoor mould. We are also helping to avoid future issues resulting from changes to materials, designs and construction methods. Ultimately, we'd like New Zealand to have homes that manage moisture properly and have safe indoor environments.

In short, this programme recognises that the performance of the building envelope is linked to the environment within the building and aims to form a complete model of how buildings manage contaminants (including moisture). This would allow designers and builders to assess the impact of any features they want to implement.

The WAVE programme is split into four complementary streams:


A successful WAVE programme will provide a performance basis for weathertight design - removing some of the guesswork from current practice and ensuring a dry and safe future for the New Zealand building stock.
