Instant baseline buildings for LCA and easy design optioneering


Watch this short video to see how Carbon Designer can help you find out more sustainable material and design options for your project, even in the earliest stages. Carbon Designer can be used to identify carbon reductions in any construction project.

It also works with any One Click LCA module. It can generate baseline building for LEED v4 (archetype or alternative design options), create BREEAM 2018 concept stage options, and more. This add-on is available now.

Easy Baseline Building

Create a baseline building for LEED v4 easily

Building life-cycle impact reduction Option 4: Whole-Building Life-Cycle Assessment requires the creation of a Baseline building and a minimum of 10% reduction between the final project and the baseline. With Carbon Designer, you can create your LEED-compliant baseline building (archetype or alternative design options) quickly.

LCA and LCC Made Easy

Create Concept Phase options for BREEAM Mat 01 LCA

One Click LCA helps to design and deliver Mat 01 LCA options for BREEAM UK NC 2018 easily and efficiently. One Click LCA is the only software approved for all of BREEAM UK NC 2018 and holds uniquely a 100 % verified score for BREEAM Mat 01 LCA. It is also compliant with LEED v4 and many more certifications.

Concept stage decarbonization

Calculate early-stage LCA just with building shape and size

Carbon Designer allows you to quickly create an LCA just by building shape and size for a baseline or calculation purposes. You can easily vary structures, material choices, as well as specification. As only limited information is needed, this works well for the first stages of a project.

What our users have to say about One Click LCA

One Click LCA allowed us to deliver an LCA in a schedule we could otherwise hardly have met. The tool is very flexible, standards-compliant and has a competent support.

Andreas Asker

Miljökonsult, WSP Sverige AB, Sweden

One Click LCA is very intuitive, has a large materials database and fast support. I’d definitely recommend it, and we are looking forward to using it in future projects.

Erlend Kulander

Kvitrud, Energirådgiver, NIRAS, Norway

I have been working with One Click LCA for about 6 months: it is easy to learn and user-friendly. I would recommend this tool for every future user.
