BU655 Building blocks for new-build-net-zero carbon houses

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.

BU654 Installation and maintenance of solid fuel appliances

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.

BU653 Damp-proof membranes to concrete slabs

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.

BU652 Amendments to Acceptable Solutions and Verification Methods for B1 and E2

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.

BU651 Climate change, net-zero carbon and the building industry

Recent calculations suggest that the built environment accounts for up to 20% of New Zealand's greenhouse gas emissions. Both new and existing buildings will need to produce fewer emissions to help meet net-zero carbon targets set in law. 

This bulletin provides an introduction to the impacts of climate change and the move to a net-zero carbon economy on the New Zealand building industry.

Module: Building consent challenge

This module is for anyone who is or could be involved in the building consent process. You’ll start with five projects, but not all of them will need consent.

To pass this module, you need to work through the steps for the rest of the projects to get a Code Compliance Certificate for each.

Gain 100% in the test at the end of the module, and you'll receive a record of your completion that can be submitted as part of your CPD activity log.

Module: Properties of moisture

The structure and behaviour of moisture can help us understand why a house is having weathertightness issues and how to design to avoid those issues. Weathertightness issues in houses can lead to health problems, financial headaches and structural worries.

Topics covered in this self-paced module:

  • Why is moisture important to understand?
  • What form does HO take?
  • How does it behave?
  • Library of useful material

Gain 100% in the test at the end of the module, and you'll receive a record of your completion that can be submitted as part of your CPD activity log.

Module: Introduction to moisture

Moisture can make its way into a house in a range of ways - exterior, interior, ground and construction. This module focuses on the effects of moisture on houses and the people who live in them.

Topics covered in this self-paced module:

  • Where does it come from?
  • Why is it important?
  • In the past
  • Library of useful material

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 Data Entry

This is a lighter version of LCAQuick that allows you to sort and format your data correctly but does not contain the functionality to calculate environmental impacts. Once your data is in the correct format, you can copy and paste it into the full version of LCAQuickV3.4.3, which will then calculate the environmental impacts.

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.
