You will see two versions of LCAQuick - one with the suffix "BLANK" and the other with the suffix "BLANK_INPUTS ONLY".
The "BLANK" version is the full working version of LCAQuick, which calculates environmental impacts based on the data you enter. Due to the size of the file, and the numbers of calculations that are performed, it can be slower.
If you wish, you can use the "BLANK_INPUTS ONLY" version initially to sort and enter your data. This version is a slimmed down copy that contains the functionality to enable you to enter data in the correct format but does not contain the functionality to calculate environmental impacts. Once you have your data in the correct format in this version, you can then copy and paste all the data into the "BLANK" version, which will calculate the environmental impacts. This process can be quicker and easier.
Note: that the "BLANK" version of LCAQuick is a 56 MB file, so it is best to use LCAQuick on a reasonably powerful computer. Also, please ensure that you are using Microsoft Excel from 2016 or later.
LCAQuick is primarily aimed at architects, designers, structural engineers and their clients, who want to evaluate the climate change (and other environmental impacts) associated with their building design. It can be used by anyone with an interest to understand the environmental impacts of buildings across the life cycle.
LCAQuick is a free tool aimed at informing early (concept and preliminary) design decisions.

Training and support
YouTube training videos are available by going to YouTube www.youtube.com/user/BRANZmedia/playlists and selecting the "Building LCA" playlist. These were developed for the first version of LCAQuick, but much of the functionality remains the same.
We have an LCAQuick LinkedIn forum where we post answers to frequently asked questions.
If these don't help with your query, please email us using LCAQuick.firstname.lastname@example.org.
BRANZ provides free training and support to architects, designers, structural engineers and their clients who want to learn more about how to apply carbon footprinting and LCA to buildings, and/or who want to learn how to use LCAQuick.
