Designing offices in line with our values and mission. Test our environmental assessment tools and methodological approach. Have a traditional developer and a young company specialized in the manufacture of reused wood furniture work together. Calculate the environmental impact and circularity of a development project...
A look back at a project where reuse, the quality of the service providers and elbow grease made the difference.
▪️The starting situation
2021. That year, contrary to the song, it wasn't rock'n'roll that opened its wings, it was EVEA that took flight. The result: a growth in the number of employees in our offices in Lyon and Troyes, but above all in Nantes, a city that is home to two marvels: the Château des Ducs de Bretagne and EVEA's headquarters, just a stone's throw from Place Graslin. High ceilings, beautiful moldings, but room for 25 people, while we were nearly 40.
A meaningful project
The team in charge of the development project had one goal: that this project reflect EVEA's values and professions, through a sober development, and above all :
Controlling our costs
On the financial level too, sobriety was the order of the day. Each expense was carefully considered, and the creation of a provisional budget quickly served as a control panel. The idea was to have a framework, a global envelope and a straw for the thirst in case of misadventure.
▪️Time to choose
In the heart of the city
The location of the new office was not chosen at random. We chose the 3rd floor of a relatively new building on the Île-de-Nantes, rue Arthur III. In the heart of the city and the Creation district, easily accessible by bike, streetcar or bus.
Reuse, reuse, reuse
This was our leitmotiv. To minimize our impact, we not only kept all of our equipment from the old premises, but we maximized what existed in the new premises. We did not wipe out the past, we capitalized on the present to set the table for our future. A somewhat frugal method, but quite virtuous.
Our building team calculated the environmental benefits of the choices that were made, thanks to a calculation tool (designed by Tim Osmond and Emmanuel Peteuil) of the circularity footprint. You will discover below all that this tool allowed us to calculate.
A dedicated team
To concretely carry out this project, we gathered 6 volunteers, who, in addition to their daily work, moved each step forward every week for 9 months, keeping the teams regularly informed.
A specific set of specifications
The specifications took into account the functional needs of the teams and the environmental requirements:
Results are in
In the end, the results were satisfactory:
Our kitchen in its "raw" state: a set bought on Le Bon Coin, dressed and optimized by our partner 100 Détours (overcycled wood worktop and sanded oak panels)
▪️The reuse to the test of numbers
At EVEA SAS Cooperative, we provide consulting, training and software tools. To measure our environmental indicators, we used one of the tools developed as part of an office design impact reduction project.
The objective of the tool: to evaluate the environmental benefits by tracking the following indicators:
The emission factors are derived from:
Indicator results for EVEA ^^
Comparative table of circularity indicators between a standard layout and the EVEA layout ^^
The comparison of the circularity rates with a "standard" development shows that our reuse strategy has paid off.
We "avoided" about 45 kg CO2 eq/m2 SDP. In other words, if we compare ourselves with a standard development project (with new materials), we have divided our carbon impact by about 2 by reusing. This strategy is also visible when we look at the balance of incoming materials, with 79% of materials recycled, reused or re-employed.
In conclusion, the results of these calculations are quite interesting. However, it is not easy to achieve such results. Why not? Precisely because nothing is standardized and this type of work is still made to measure. Today, re-use is not the norm. It is done outside the traditional circuits. It requires a lot of elbow grease and a good knowledge of local actors. But it is feasible in office design, it is perhaps easier than in other sectors. And it's worth the effort. ▪️
