What our users have to say

I love this approach… To make LCA as easy as possible. Petr Lhoták

Green Business Senior Specialist, Skanska, Czech Republic

Incorporating One Click LCA as a tool in the building design stage has helped us evaluate, prioritize and optimize our efforts in reducing the lifetime environmental impacts of the projects we design. With One Click LCA uploading, managing, and evaluating data has become very fast and easy through its automated process which links materials with relevant LCA data from the software’s abundant product database. One Click LCA provides the detailed information we need to implement design solutions which are substantially reducing the environmental impacts of our projects. Natalia Quintanilla

Building Science Specialist, Smith + Gill Architecture, USA

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

One Click LCA delivered the maximal 6+1 credits for BREEAM LCA. The software is really easy to use and does not require special expertise. I am happy to recommend it. Riina Salomaa

Project Engineer, Optiplan Oy, Finland

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

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. Eryk Ostrowski

BREEAM certification specialist, Sweco Consulting, Poland

I have used One Click LCA both for commercial projects and education purposes and I am happy to say that the software is extremely intuitive and can be used by anybody, no matter their level of expertise when it comes to Life Cycle Assessment. Carlotta Cocco

LEED AP BD+C, ID+C, BREEAM Assessor, Architect, Evotre

I learned a great deal from using One Click LCA over the last year and from the web training sessions I attended. This definitely had a positive impact on the building projects I participated in during that time. Clément Jaffrelo

Sustainable Building Engineer, Sinteo, France

It works in a cloud which is handy. It has nice visual interpretation of results. Quite substantial database. A lot of default options that can be used like average European transport impact. The input can be uploaded, and the results can be downloaded for further usage.

Capterra review Marcin Cierpisz

Project Manager, Sweco Consulting

The customer service is amazing! I have had people personally emailing me, setting up personal tutorials to make sure I got up and running. The results are easy to see, understand.

Capterra review Rachel Nicely

Sustainable Program Manager, Sustainable Building Partners

Software capabilities allowing to achieve high score under BREEAM International certification are amongst the most valued features. Data import from *.IFC file when the file is of appropriate LOD reduce the amount of man-hours needed to complete the project.
