Certain types of wastewater from households (greywater from baths, showers and bathroom basins and sometimes from laundry tubs and washing machines) can be reused for subsurface garden irrigation and flushing toilets.

Rainwater systems can provide water suitable for drinking and food preparation if it is filtered and/or treated adequately and can also be used for garden irrigation, swimming pools, toilet flushing, baths and showers.

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.

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

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

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.

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 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.

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

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