This 20-minute module provides comprehensive guidance on the design and construction of steel-framed buildings and steps learners through a diverse range of fundamental topics including walls, floors, and rafters; roof structure; insulation; thermal breaks and underlays; wiring and piping; fire and acoustics; windows, doors and wall cladding; bracing; and foundations and connections.

This 20-minute module gives designers in-depth, practical guidance on design principles and considerations for lightweight steel framing that differ from timber construction. This module includes preplanning; steel basics; fixings and connections; and on-site remediation. 

This 20-minute module steps designers and builders through the basics of steel-frame buildings. By completing these building blocks, you will gain an understanding of statutory requirements; materials and specifications; linings, thermal breaks, and insulation; and floors, roofs, and walls.

Provides calculated carbon footprints per square metre for residential roof, wall and floor constructions, obtained from the BRANZ House Insulation Guide (5th edition). 

Using this guide This framework is intended for the management of council-owned buildings only. It is not intended to guide a council’s regulatory responsibilities for managing all earthquake-prone buildings in their area in general.

This BRANZ/Edge Environment webinar explores the need to move to a circular economy – one that also addresses climate change and modern-day slavery.

This webinar explores BRANZ Levy-funded research into higher-than-expected percentages of framing, and therefore thermal bridging, found in residential construction in New Zealand.
