Using case studies for a simple house and a complex house, this module illustrates the design of a variety of junctions and the issues to consider.

This module provides an introduction to junction installation for LBPs. It covers what are junctions and why they are important; how water behaves; flashings, penetrations, sealants, and sequencing; what you need to know before you start building; common issues and problems during installation.

A junction is where materials meet or change direction and can be a weakness in the weathertightness of the building envelope. This module covers how water behaves; why junctions are important; the different types of junctions. 

When designing junctions, we need to consider the situation or context that the junctions are in, the appropriate materials we need to use, and the best design practices. This module covers geographical location; suitable materials; designing flashings and penetrations; designing for maintenance.

This bulletin describes approaches for upgrading thermal performance including reducing air infiltration, replacing ordinary single glazing and retrofitting insulating glass units (IGUs).

(This bulletin updates and replaces Bulletin 507).

Timber window installation is outside the scope of Acceptable Solution E2/ AS1, so building consent must be applied for as an alternative method

(This bulletin updates and replaces Bulletin 481).

This webinar takes you through the results of a recent BRANZ research into the appetite for using EWPs in building, the perceptions that exist about them and potential barriers.  It also covers the range of resources available in New Zealand to help make decisions regarding the use and performance of EWPs and the what the implications of their use might be and how to effectively incorporate them into building projects.

The primary concern for water supply design in a house will always be the health and safety of the occupants, but beyond that, there are opportunities to reduce consumption of reticulated water through efficient design.

This bulletin gives an overview of passive design options for reducing overheating. It does not consider active (mechanical) ventilation systems.

Hear how BRANZ is investigating the performance of Structural Insulated Panels (SIPs) under New Zealand's climate, and in the case of an earthquake or fire.

This module covers D1/AS1 design requirements for curved and winder stairs.

This module covers design and construction requirements for barriers, specifically in relation to stairways.

This module provides an introduction to stairway design following D1/AS1 including specifications and features that are required for safety and ease of use.

This module covers design and construction requirements for landings, including quarter and half landings.

This module covers D1/AS1 design requirements for exterior stairs.

This module focuses on stair handrails, including when and why they’re used, and specifications for handrail design in different situations.

Greenhouse gas emissions from new building work must be reduced for New Zealand to meet its commitment to a net-zero carbon economy. 

This bulletin gives an overview of the decisions that designers, builders and clients can take to reduce the carbon footprints of new houses.

This is the second of two bulletins on net-zero carbon building. It follows Bulletin 651 Climate change, net-zero carbon and the building industry.

This bulletin outlines considerations for installation, use and maintenance of solid fuel appliances. Solid fuel-burning appliances can be free standing or built in. Terms used for built-in appliances include inbuilt heaters, fireplace heaters, inset or insert fires, slow combustion solid fuel stoves and solid fuel space heaters, which may be installed in an existing fireplace and/or chimney or in a new construction.

Solid fuel appliances, including flue pipes and chimneys, must be regularly cleaned and maintained.

This bulletin replaces Bulletin 306 Inspection procedures for chimneys, fireplaces and solid fuel burning appliances.

Damp-proof membranes (DPMs) or concrete underlays are necessary under on-ground concrete floor slabs to prevent moisture from the ground passing through the slab and damaging the interior finishes, fittings and contents.

The use of a DPM is mandatory under slabs on ground for all habitable spaces and under slabs for garages or ancillary buildings that may be used as habitable spaces in the future.

This bulletin outlines the selection, design and installation requirements for DPMs. It updates and replaces Bulletin 469 of the same name.

Acceptable Solutions and Verification Methods provide a means of demonstrating compliance with the relevant clauses of the New Zealand Building Code (NZBC). It is not mandatory to use Acceptable Solutions and Verification Methods, but if used, building consent authorities (BCAs) and territorial authorities must accept them as providing compliance.

This bulletin highlights some of the key changes to New Zealand Building Code Acceptable Solutions and Verification Methods for clauses B1 Structure and E2 External moisture that have come into effect since 2012. It highlights the amendments introduced in 2019.

This bulletin replaces Bulletin 545 Key changes to B1/AS1 and E2/AS1.
