Strong wind causes damage to houses, particularly their roofs. A recent BRANZ study started by defining ‘extreme winds’ before developing retrofit solutions to ensure roofs on older houses are adequately secured.

With the help of BRANZ data, the Riskscape joint project between NIWA and GNS aims to better predict the costs of damaging wind events on buildings.
There are sometimes significant discrepancies between the predicted and actual building sway in taller buildings. A new study aims to develop an improved methodology for wind design of buildings.
Research shows that, apart from some slight changes, light timber-framed buildings designed using our current standards should largely stand up to the increased wind speeds that climate change is expected to bring.
A BRANZ research project has investigated load transfer in timber framed buildings – and found a number of potential weak spots.
BRANZ investment combined with Scion expertise has developed a new structural connection system for timber-framed multi-residential units that maintains acoustic performance.
Recent BRANZ testing has quantified the bracing ratings of some common older generic bracing systems. These ratings will be useful during repairs or renovations of older buildings.
Recent BRANZ research has shed new light on how evaporative drying in wall cavities depends on cavity dimensions, vent sizes and climate.
Creating a compliant bracing distribution system can be a challenge in today’s open plan house designs. Even if you don’t design them, it is still important to understand how bracing works.
More thought is needed on how the construction industry, known for its waste, can fit into the circular economy. In New Zealand, timber framing technology is being developed that allows for future reuse.
