Action research

Efficacity loses no time in testing its research work against the realities on the ground.
To obtain Efficacity’s support, each research project must describe at least one concrete field application, and this application must be recognised as useful and pertinent by one of our territorial partners. That partner must then agree to deploy a prototype or, ultimately, a physical demonstrator, in its territory.
Our research teams thus benefit from real-world data and concrete case studies and, more important still, close proximity to operational actors ensures that the right questions are asked of the science, and that the results of the research will lead to market opportunities.


Efficacity is developing new concepts at the point where the research work of the R&D ecosystem meets the operational needs expressed by our industrial members and territorial partners. To nurture these new concepts to fruition, Efficacity relies on the skills and technical building blocks made available in the laboratories, and on the operational expertise offered by the members of the consortium.

The institute develops prototypes without waiting for concepts to mature, adopting agile development methods to ensure that critical analyses by the consortium’s networks of operational experts (Technical Committees) and by the networks of end users (Partner Committees) are dealt with as and when they arise.

Efficacity makes field testing systematic : no sooner have the functionalities of the first prototypes been tested than these prototypes are deployed in one or more of Efficacity’s partner territories to contend with real-life situations. Efficacity has a large number of R&D agreements in place with various territories ready and willing to put teams into action, and to provide not only data but also sites where the solutions developed by Efficacity can be beta-tested.

Efficacity supports its productions until they reach the market  by ensuring, either directly or via its members, that its methods, data and tools are commercially oriented. Everything that emerges from the institute is thus ultimately intended to evolve into a validated commercial offering, packaged and available through a range of distribution channels and open to all those involved in urban design and management.



Efficacity brings together skills ranging across dozens of professions involved in energy transition. The institute supports its members and partners in upskilling though communities of skills. These communities are run by means of scientific mentoring provided by eminent figures from the top-ranking laboratories included in the consortium.

Efficacity’s aims

Efficacity strives towards the emergence of a new form of integrated energy planning for urban territories, in order to set objective investment priorities at a time of both bold environmental ambitions and budget constraints for territorial actors.


Efficacity offers solutions for improving the design of urban construction and renovation projects by predetermining families of solutions best suited to the various urban contexts, designing dynamic district-scale energy simulation tools for conducting design studies, and proposing tools for dialogue between stakeholders.


Efficacity promotes progress in urban monitoring, introducing new optimisation criteria and new ways of managing urban hubs, public spaces and, gradually, whole districts, in order to verify and improve the quality of use and the real performances these districts can provide.


For Efficacity, urban energy transition calls for the emergence of a truly “performance-oriented approach”. This involves a shift from a best efforts commitment to a commitment to performance or impacts. As part of this process, Efficacity is helping to identify new frames of reference and performance-oriented labels covering all the phases of the project lifecycle and looking at the real impacts of the actions embarked upon.

A win-win relationship with French startups and SMEs

Well aware of the teeming ecosystem of innovative French startups/SMEs in urban energy and environmental transition, Efficacity has been swift to establish fruitful relations with these research programmes. Targeted collaborations have created opportunities for accelerating the development of certain research projects and for providing startups/SMEs with scope for experimentation, in a win-win environment. Keen to promote still more collaboration on projects jointly supported members and by the territories offering the testing grounds, Efficacity is currently pursuing collaboration with business incubators and accelerators.
