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 research has quantified one aspect of an important but often overlooked factor for achieving a dry home – occupant use.
The current technical review of our timber-framed building standard is limited by the rapid rate of change still occurring in the industry.
Heavier windows and drained and vented wall cavities mean loadings from windows are often offset from the timber framing. Recent BRANZ research checked that a modified support bar system can transfer the load back to the framing to prevent problems.
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.
In a New Zealand first, a fire engineering computer program being developed by BRANZ will automate design fire generation and change current design practices with their inherent inconsistencies.
