Retrofitting to resist extreme wind

By Graeme Beattie – 1 August 2008, Build 107

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.

Wind effects on buildings

By Graeme Beattie – 1 June 2010, Build 118

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.

Design prediction of wind-induced building motion

By Ian Wells – 1 April 2009, Build 111

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.

Are buildings ready for climate change?

By David Carradine, Nick Locke – 1 June 2022, Build 190

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.

Maximum strength of house bracing walls

By Stuart Thurston – 1 February 2008, Build 104

A BRANZ research project has investigated load transfer in timber framed buildings – and found a number of potential weak spots.

Code changes

1 October 2011, Build 126

Changes to key Building Code documents dealing with building structure (B1) and weathertightness (E2) came into effect on 1 August 2011.

Carports without consents

By Reza Sedgh, Te Zhang – 1 December 2020, Build 181

From 31 August 2020, a range of new and extended building consent exemptions were added to Schedule 1 of the Building Act, including a range of options for building carports.

The printed house

By Dael Climo – 1 August 2014, Build 143

3D printing is exciting plenty of interest. In the construction world, work is under way on a complete building and steel structural elements.

Advanced façade systems

By Rob Teterin – 1 August 2020, Build 179

Emerging complex building façade designs can take up to a year to test, consent, fabricate and install. This makes it important for the project team to be on the same page from the start when it comes to design parameters.

Open windows for dry home

By Peter McDowall – 1 February 2017, Build 158

Recent BRANZ research has quantified one aspect of an important but often overlooked factor for achieving a dry home – occupant use.
