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.
A BRANZ research project has investigated load transfer in timber framed buildings – and found a number of potential weak spots.
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.
The current technical review of our timber-framed building standard is limited by the rapid rate of change still occurring in the industry.
A BRANZ program has the answers for those keen to understand how vents in cavity walls help keep walls dry. By using this knowledge, keeping it simple and following the 4Ds – drying, deflection, drainage and durability – walls will be weathertight.
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.
A Building Research funded study report investigated the recent shift toward the use of domestic heat pumps, and found that its likely effects are both positive and negative.
