This Microsoft Excel (.xlxs) 25MB download of BRANZ House Insulation Guide 6th edition is for PC and MAC users of Microsoft 365 [ONLINE]

Updates:

• A new 'Summary' sheet has been added to the tool
• An error has been repaired where the R-value for plain slab floors was higher than it should have been when adding floor topper insulation
• Improvements to the 'Correction for reduced perimeter insulation' section of the 'Roof spaces' 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.

Once you have downloaded this version open it using Excel on Microsoft 365

Note that the schedule method will be removed from the Acceptable Solution H1/AS1 later in 2025. There will be a 12-month transition period while its use is phased out.

Use LCAPlay to evaluate the potential greenhouse gas emissions (and other environmental impacts) of alternative building options.

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. 

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.

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.

Provides calculated carbon footprints per square metre for residential roof, wall and floor constructions, obtained from the BRANZ House Insulation Guide (5th edition).

BRANZ and the University of Canterbury worked together to develop B-RISK from the BRANZFIRE deterministic fire model. This collaboration was funded by the Ministry of Business, Innovation and Employment and the Building Research Levy.

The continued support and maintenance of B-RISK is funded by the Building Research Levy.

B-RISK allows several features to be integrated within the design tool to simulate building fires such as:

• a design fire generator and item-to-item fire spread module allowing building contents to be randomly placed within a room and the overall rate of heat release to be determined
• a comprehensive sprinkler response module including operation of multiple heads and parameters for effectiveness and reliability of sprinkler systems
• Assignment of hold-open devices to doors and open/close vents using a range of trigger criteria
• Vent flows and smoke migration
• reliability of other systems such as smoke detectors, mechanical systems and passive elements such as doors
• C/VM2 user mode - useful for fire analysis required to be in compliance with the New Zealand Building Code
• visualisation of geometry and results using Smokeview software
• Monte Carlo multi-iteration sampling for probability/risk analysis
• the inclusion of various types of balcony spill plume relationships to facilitate the design of smoke management systems within buildings.
