Seminar: BRANZ Answers 2021

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 houses, townhouses, apartments and so on) to ensure such decks will be serviceable over the life of the building.

There are two compliance paths for waterproof decks – Acceptable Solution E2/AS1 and specific design. This guide focuses on E2/AS1.

This Good Practice Guide will be an essential reference tool for all those involved in the selection, design or construction of waterproof decks.

Note that membranes must be applied by certified contractors or approved applicators, and this guide is not intended as a how-to guide for inexperienced or non-approved applicators to apply membranes.

This is the full working version of LCAQuick, which calculates environmental impacts based on the data you enter. If you wish, you can use LCAQuickV3.6 Data Entry initially to sort and enter your data.

This version of LCAQuick is a 40 MB file, so it is best to use it on a reasonably powerful computer. Due to the size of the file and the numbers of calculations that are performed, it can be slower. 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. 

Roof gutters are an important component of the building envelope, designed to control the disposal of rainwater from the roof. The most important functions of gutters are to help protect against:

• excessive or concentrated wetting of external wall surfaces
• water getting inside the building roof space or wall framing
• increased wetness of soils around the building and subsequent increased moisture loads on basement waterproofing 
• undermining of areas around the building where there is controlled spillage onto the ground.

Leaking or overflowing gutters may cause problems with dampness in subfloor areas or basements or elevated moisture levels in cladding and within wall framing.

This Good Repair Guide covers the repair or replacement of fully accessible metal and plastic external gutters around the outside perimeter of the building that are fixed to a fascia board or rafter ends. It does not cover gutters that are concealed behind a proprietary metal fascia or internal or within-roof gutters.

This publication helps designers, specifiers and builders ensure that new and existing houses are warm and effectively ventilated, providing owner comfort, convenience, health and safety while minimising running costs. It acknowledges the importance of good passive design - taking advantage of free sources of energy such as sun and wind to provide heating, cooling and ventilation.

This publication covers:

• heating and cooling design considerations and methods
• thermal design
• ventilation design considerations and methods.

Until the 1970s, the main material used for window frames and sashes in New Zealand houses was timber. A large proportion of houses still have timber windows, and these can last for a very long time if well maintained and repaired when necessary.

This Good Repair Guide covers the repair of timber windows using materials and styles to match the existing. It looks at common problems, how to repair and replace windows, rules and regulations and health and safety.
