Make better-informed decisions about building materials, construction methods and designing healthier, safer and more sustainable houses using our range of calculators and tools developed from BRANZ research.
LCAQuick is a free tool developed by BRANZ that helps architects, designers and structural engineers make sustainable design decisions. It evaluates the carbon footprint and other environmental impacts of a building design.
BRANZ CO₂NSTRUCT provides values for embodied greenhouse gas and energy for some construction materials. Embodied energy is provided as a total and divided into energy from non-renewable and renewable sources.
This aims to improve the building consent authority building inspection process. Artisan is a digital solution that enables each key step in the residential build inspection process to be prescribed, seen, assessed, verified and recorded.
TR8 software is a model to predict the fire resistance of concrete slabs and floor systems and can be used for the design of reinforced or prestressed concrete floor systems when required to have fire resistance.
B-RISK fire risk modelling software allows fire simulation results to be presented in a probabilistic form and allows the variability and uncertainty associated with the predictions of the fire environment to be quantified.
Select the climate zone and wall construction type(s) and enter area and construction R-values for the various building elements. The tool applies the calculation method automatically, and pass/fail compliance is determined.
This outlines the P21 test method for wall bracing elements, which is called up in NZS 3604:2011 Timber-framed buildings as the means to determine wind and earthquake ratings of timber-framed sheet-lined bracing elements for buildings.
