Cavity battens play a vital role in building weathertightness but must be installed properly to avoid trapping moisture in the wall cavity. This bulletin provides guidance about the selection and installation of cavity battens considering Acceptable Solution E2/AS1 and Alternative Solutions. It includes and replaces content from Bulletin BU582 Structurally fixed cavity battens. 

The Homestar Embodied Carbon Calculator (HECC) is a free tool that assesses the cradle-to-cradle life cycle embodied carbon of homes with traditional constructions (e.g. timber/steel framed homes).

This bulletin provides guidance in specifying floors that comply with the 5th edition of H1/AS1 and H1/VM1. This issue includes an overview of the requirements for slab floors and suspended floors; application of the Verification Method and when to use the modelling method set out in Part 2 of H1/VM1 might be used.

This webinar provides a basic introduction to life cycle assessment (LCA) and calculating the carbon footprint of a building. Life cycle assessment underpins all BRANZ carbon tools, so this webinar is a recommended introduction to our other carbon tools webinars.

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.

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 bulletin updates and replaces Bulletin 523 Reducing waste from building sites. It focuses on houses and small buildings.

Use LCAPlay to evaluate the potential greenhouse gas emissions (and other environmental impacts) of alternative building options.

This bulletin outlines the BRANZ tools available to architects, designers and engineers to produce houses that have lower carbon footprints.

This bulletin gives guidance around proving compliance with H1 using the 5th edition of H1/AS1 and H1/ VM1.

This is a lighter version of LCAQuick that allows you to sort and format your data correctly but does not contain the functionality to calculate environmental impacts. Once your data is in the correct format, you can copy and paste it into the full version of LCAQuickV3.5, which will then calculate the environmental impacts.

Please ensure that you are using Microsoft Excel from 2016 or later.

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. It can be used by anyone with an interest to understand the environmental impacts of buildings across the life cycle.
