This bulletin provides a range of universal design considerations for ensuring new and existing homes are accessible by vehicle.

This bulletin provides a range of universal design considerations for ensuring the routes to new and existing homes are accessible.

This BRANZ Answers seminar gives answers to a wide range of practical questions relating to new ways of doing things in the residential building and construction industry. We cover new types of buildings, new types of products and systems, new ways to increase the performance of buildings, and upcoming regulatory changes.

This bulletin describes five highperformance residential wall details that give significantly better thermal performance than traditional construction.

This bulletin describes five highperformance residential roof details that give significantly better thermal performance than traditional construction.

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. 

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.

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 book aims to provide background to the issues and contributing factors and guidance on the principles of weathertight construction – how water behaves and how we deal with it.

This guide focuses on the ‘good’ design, specification and construction requirements for all types of waterproof decks and balconies (Building Code, structure, substrate, membrane and walk-on surface) to residential buildings (stand-alone houes, townhouses, apartments and so on) to ensure such decks will be serviceable over the life of the building.

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.

The session will cover underslab drainage (applicable to all classes of buildings) and a number of plumbing stack systems.

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