There are two versions of LCAQuick - both are free:
This is the full working version of LCAQuick, which calculates environmental impacts based on the data you enter. (Using LCAQuick Data Entry to sort and format your data first can make the calculation process quicker but it is not necessary.)
LCAQuickV3.4.2 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, which will then calculate the environmental impacts.

Use LCAQuick to conduct a life cycle assessment (LCA) and understand the potential environmental impacts of a building design across the life cycle. The latest version of the tool includes:
- evaluation of different building typologies
- a reference building library for:
- 10 commercial office buildings in three climate zones
- eight stand-alone houses, one medium-density housing and one apartment building in three climate zones
- environmental impact of materials used in commercial office building and residential housing construction in New Zealand
- operational energy use from grid electricity
- comparison of alternative constructions based on embodied carbon
- a tool to calculate material quantities of windows and doors based on window/door type and frame material
- a Green Star outputs worksheet that puts LCA results into a format that can be pasted directly into the New Zealand Green Building Council's LCA calculator tool [XLSX, 383 KB]
- a separate editable PDF template report to support a Green Star submission for obtaining the LCA points under credit 19A.
The full version of LCAQuickV3.4.2 is a 57 MB Excel spreadsheet, so it runs best in Microsoft Excel from 2016 or later on a reasonably powerful computer.
The first version of LCAQuick was released in November 2016. Version 3.4 was released in March 2020. See LCAQuick: Version history for a list of the main features and major changes between versions.

Inputs to LCAQuick
LCAQuick has been designed so that it can be used with any building information modelling (BIM) tool.
It requires the following inputs:
- Headline information about the project such as building or project name, project number and gross floor area.
- Material quantities either as a material take-off from a BIM tool or developed by a quantity surveyor - SR350 New Zealand whole-building whole-of-life framework: Development of reference office buildings for use in early design provides guidance on the required minimum level of development required for BIM objects.
- Results of an energy simulation - default values are provided in the datasheet New Zealand grid environmental impacts 2018-2050 (module B6) [XLSX, 152KB].
- An estimate of water consumption - default values are provided in the datasheet Operational water (module B7) [XLSX, 131 KB].
Training and support
BRANZ provides free training and support to architects, designers and structural engineers who want to learn more about how to use LCAQuick or how to apply LCA and carbon footprinting to building designs.
To arrange training, please email LCAQuick.firstname.lastname@example.org.
LCAQuick training videos are available from the BRANZ YouTube channel. These were developed for the first version of LCAQuick but much of the functionality remains the same.
