  • What is the schedule method?
  • How does it work?
  • How could I go further?
  • Library of useful materials

BU650 Building beyond Code minimums

The New Zealand Building Code sets out performance criteria that all building work must comply with. Minimum requirements in the Code, in Acceptable Solutions and referenced standards cover areas from thermal insulation to ventilation levels.

Many new houses are constructed to just meet the minimum requirements of the New Zealand Building Code. Better-performing houses may cost more to build but are much more comfortable to live in and have reduced running costs to offset the upfront cost.

Our houses will need to perform considerably better to help meet long-term national net-zero carbon targets.

LCAQuickV3.4.3

This is the full working version of LCAQuick, which calculates environmental impacts based on the data you enter. If you wish, you can use LCAQuickV3.4.3 Data Entry initially to sort and enter your data.

This version of LCAQuick is a 55 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. 

BRANZ CO₂NSTRUCT

BRANZ CONSTRUCT provides embodied carbon and energy values for building materials, including concrete, glass, timber and metals, as well as products such as bathroom and kitchen fittings and lifts.

Embodied carbon is the amount of greenhouse gases, expressed as carbon dioxide equivalents, required to produce a material. Embodied energy is the amount of energy consumed to extract, refine, process, transport and fabricate a material or product (including buildings). This is provided as a total and divided into energy from non-renewable and renewable sources.

This datasheet is provided as part of BRANZ's development of the New Zealand whole-building whole-of-life framework.

BU649 Corrosion of metals in New Zealand buildings

Corrosion is a chemical or electrochemical reaction between a material and aggressive substances in its surrounding environment. The interaction normally leads to the material being consumed and a reduction of performance, durability and/or visual attractiveness. A common example of corrosion is the rusting of steel, which converts the metal into compounds such as oxides, hydroxides or sulphides.

The economic cost of corrosion is enormous. One New Zealand estimate put it at the equivalent of 2.5% of gross domestic product (GDP) or around NZ$7.5 billion, while another put it at NZ$9 billion. International studies have estimated the annual cost of corrosion as the equivalent of 2-6% of GDP. 

This bulletin gives an overview of the corrosion of metals in New Zealand buildings and explains how corrosion can be reduced and managed. BRANZ scientists have researched corrosion for over 40 years, and much of the content in this bulletin reflects their findings.

BU648 Timber shingle and shake roofing

Timber shingles and shakes have been used as a lightweight roof cladding in New Zealand for around 200 years. They are mentioned in current design guides for many heritage areas, but they are also found in contemporary styles of housing.

Shingles are sawn, have relatively smooth faces and usually have random widths and taper in thickness. Shakes are usually hand split (although some are also sawn) and usually have a rougher textured surface on at least one side. Widths are generally random. 

Shingles and shakes are usually manufactured from residual timber left over from the main forest log production. They have a relatively small carbon footprint compared to some other roofing materials.

This bulletin outlines the selection, design and installation of timber shingle and shake roof cladding. It updates and replaces BRANZ Bulletin 443 Timber shingles and shakes.

This bulletin covers:

  • legislation
  • recessed luminaire classifications
  • installation requirements generally

BU645 Installing timber strip flooring over timber joists

Poorly installed timber strip flooring can result in problems such as cupping, warping, buckling and squeaking of boards. The main causes of problems are installing flooring before the building is fully enclosed, high moisture levels, boards of insufficient thickness and joists too far apart.

This bulletin describes the requirements for installing timber strip flooring over timber suspended floor framing and outlines finishing options and maintenance requirements. It replaces Bulletin 390 Laying timber strip flooring over timber joists.

This bulletin covers:

  • subfloor framing
  • timber flooring
  • installing timber strip flooring
  • floor finishes, cleaning and maintenance.
