Bat'impact®: an accessible environmental score

The CS'score® is a complex calculation system in a very simple to use tool. It allows you to assess the environmental impact of an interior design project (and soon other types of project) without being an expert in environmental engineering.

Carbon Saver SAS, in partnership with the eco-design agency Cooperative MU, has developed the CS'score®. This calculation method is based on the analysis of data from more than 50 interior design projects.

The CS'score®: an accessible environmental score.
Choose the "right materials" and "right practices" at the design stage.

Choosing the "right materials" and "good practices" right from the design phase

For each element of a project, visual indicators help architects to choose low environmental impact materials at a glance.

A specific questionnaire for each project encourages architects to ask themselves which elements have the greatest impact. Depending on the answers chosen, the CS'score® changes in real time.

Concrete proposals prioritized to improve project scores

In addition to the CS'score®, the architect obtains a detailed report with relevant improvement advice
which evolves with the project.

From the early design phases to the implementation of the work, the architect can modify his answers to the questionnaire. The mobile site instantly updates a detailed report with new areas for improvement.

"The companion of my profession as an architect.

A simple tool [...] that allows me to learn on a daily basis, to design my projects and renovate my worksites with a healthier approach to housing. On the app I don't just calculate the impact of my worksite, I push my customers and my agency to participate in today's transition."

"To validate the environmental impact of my projects in concrete terms.

Carbon Saver has allowed me to concretely validate the environmental impact of my projects, and to be able to quantify to my clients the "savings" made through reuse and the choice of healthy and local materials"

"To have an overview of the score of a project in progress.

The carbon saver application allowed me to adjust the choices I was going to propose to clients to reduce my impact. It also allowed me to learn things, or to ask myself more questions where I hadn't yet asked myself about the impact of a particular choice."

Decorator and interior designer

"Pushing ecological design even further.

In my design projects, an important value for me is to reduce our ecological impact. I discovered Carbon Saver a few weeks ago and it's a tool that allows me to evaluate if my project respects this intention, but also gives me avenues for improvement to push ecological design even further."

Why is it free?

Carbon Saver's mission is simple: to limit the environmental impact of buildings in order to preserve the planet by simplifying the use of complex scientific calculations. We believe that preserving our environment is a common good, and we have been supported by the Ministry of Ecological Transition and the Public Investment Bank (BPI) since our creation. It has always seemed natural to us to offer a simple and free version to as many people as possible, because we firmly believe that acting for the environment is vital, and that each actor can make a difference.

In addition to this free version, we already have more complex paid versions for professionals! It is these paid versions that will ensure the sustainability and development of our solutions in France and soon on an international scale.
