BRANZ House Insulation Guide 6th edition V2.1 MAC (November 2023)

This XLXS [25MB] download of BRANZ House Insulation Guide 6th edition is for MAC users.

New Features:

  • A helpful “Door” sheet for determining the R-value of doors (leaf and frame) based on the R-value and size of the door leaf and the material of the frame. This does not include sliding doors.
  • A frame fraction estimator to the “Wall” sheet. This addition is experimental and still under development. Addtional option to note the source of the frame fraction value. That source may be for instance the frame & truss supplier, or it may have been estimated from the plans.
  • Data entry summary at the top of each of the sheets. The completed sheet can be reproduced using this character string.

Other verion updates:

  • Repaired an error with the “Roofs” sheet where the R-value included the effects of an R1.2 secondary insulation layer, even when that option wasn’t selected. It only applied to the case where the joist height was 290mm.
  • Improved appearance of the “Roof edge” sheet.

The guide is now in two parts:

  • The tables of construction R-values for common construction options for compliance under H1/AS1 and H1/VM1 5th edition
  • The accompanying House Insulation Guide text [PDF] for guidance on insulation to meet or exceed H1 AS/1 and H1/VM1 5th edition.

LCAQuickV3.6 Data Entry (June 2023)

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 LCAQuickV3.6, 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.

CO₂NSTRUCT v3 (June 2023)

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.

CO2MPARE v2.0 (June 2023)

Provides mean carbon footprint calues for New Zealand case study residential and office buildings.  Includes additional information, such as energy use intensity and top contributing materials from a greenhouse gas perspective.

LCAQuickV3.6 (June 2023)

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.
