Welcome to the
Construction Collage

A playful and collaborative workshop,

on the topic of construction

to respond to the challenges of climate change

Fun, collaborative, educational & creative,

this workshop is based on collective intelligence

by making participants actors of their Collage.

Tell me and I will forget,

show me and I may remember,

involve me and I will understand.


- Understanding the stakes

is the vehicle to accept change 

and become an actor -


Objectives of the Construction Collage

Be accessible to the maximum of people;

To alert on different issues:

climate change | biodiversity | pollution | resource depletion... ;

To provide knowledge: to give data awareness of the orders of magnitude and ressources;

To make us consider our real needs and then the courses of action;

To have a global vision of the curent impact of the construction sector on our environment.

Give the maximum of information in 3 hours to help the construction sector transition;


Who is it for?

Everyone is concerned by climate change and biodiversity loss. Construction Collage was therefore designed for people with an interest in the construction sector as well as for all construction professionals: the former will discover the subject and deconstruct their prejudices, while the latter will go deeper and question their practices.


Public workshops online and in-person.  Private workshops can be held in your premises, in a room made available to us, or online. We will think about this together when we organise the Collage.


Because the climate emergency requires us to change course very quickly. One of the keys is understanding the problem.

The data...

Building techniques and regulations vary greatly between countries and regions. We’ve gathered global data and local illustrations to raise issues.

The sources come from the following reports: IPCC, ADEME, GlobalABC, AIEA, FAO, WHO, ACAN, LETI and many more. 


How do we play?

The game is very simple. The players are in teams of 4 to 8. They have cards representing the different components linked to the construction sector and work together to find the cause and effect links by theme by positioning them and linking them together. A facilitator supervises one or more teams in order to guide them during the workshop, ensure good communication between the members and give additional explanations.

Course of the workshop

Atelier 1.png

1st part "Understanding"

During this part of 1h30, the participants discover the game cards and co-construct the Collage around different themes:

needs | urbanism | design | construction | uses and their consequences.

2nd part "Creativity"

In 25 minutes, the participants decompress and take a step back from the Collage by illustrating it, making it unique. The participants have to make their Collage as attractive, original and comprehensive as possible. They have to choose a title together, highlight the key messages, add illustrations,... This creative phase allows the knowledge to be appropriated.

3rd part "Action points"

This part lasts 1 hour and is divided into two stages:

- The participants imagine and propose their courses of action;
- In the second stage, 60 action cards are proposed. The players read them, select them and explain their choice to the others. After the discussion, they debate the most relevant courses of action and the actions to be taken.


4th part "Restitution"

In just 5 minutes, the facilitator summarises what has been learnt in order to anchor it in people's minds and to give them an overview.

The Construction Collage association

Its role is to ensure a wide dissemination of the Collage and, through this workshop, a wide dissemination of knowledge of environmental and social problems related to construction in order to provide adequate solutions.

To join the association, the first step is to have played the Collage and to apply for membership by email to the association.


The membership fee for the association is 20 euros to be paid at the ticket office for a personal subscription.


Donations to the association are welcome. They will be collected by the ticket office. The association is registered as a Loi 1901 non-profit organization in France.

The Construction Collage, or how to better understand the extent of the urgency to act and transform the building sector!

Infrastructures, development models, energy consumption, patterns, materials, uses... everything is included, and in a few hours allows us to built a good overview of the situation of the sector today.


The Collage allows to imagine solutions and debate with confidence.

It's a collective tool and I highly recommend to use it!

To meet the climate challenges, each sector must question its practices and the building sector has major environmental and social impacts.

Construction Collage is a high-quality educational tool: it helps participants to clearly diagnose the functioning of the sector and allows them to glimpse - or rather deduce - the paths to be taken for tomorrow...

In a few hours, the workshop provides a base for understanding and integrating both the current practices and the transformations to be made.

You learn better while having fun and success is based on transforming a sometimes brutal observation into a dynamic and friendly moment, which makes you want to take action. The bet on collective intelligence is successful.

This exercise is remarkable in two ways, starting with the process - the workshop combines seriousness, involvement and good humor to acquire knowledge.

A diverse range of the subjects is  raised: building materials   pollution  | GHG  | consumption  |  displacement, to compose, in the end, the Construction Collage.

Obviously, we come out of this participatory half-day motivated, united in the teams with a different outlook on the act of building.

So come and participate in the Construction Collage and get involved in contributing to the success of carbon reduction in construction!

The construction collage has enabled us to fully understand the environmental issues related to the field of construction. What drivers there are behind the environmental footprint but also and above all what levers we could activate to collectively be a little more virtuous. The collective exercise leaves room for exchange and dialogue on the subject, which is more than necessary.

We are leaving with ideas for good practices in areas that we are working on at the time of this writing. So a big thank you to the Construction Collage :)!

Have you heard of

the Climate Fresk ?

Fresque Climat.png

It is a collaborative workshop to grasp how climate change works.

Construction Collage responds to the impacts of construction on environment, and completes this workshop that raises awareness about the climate emergency.

This playful and educational workshop is based on the work of IPCC.

We strongly advise to participate in it!

Find more information on the website of the Climate Fresk..
