Comfort is not an option

The purchaser modifications and options phase is often a challenging experience both for the promoter and for its clients: time-consuming, subject to error and disappointment. is an immersive 3D application that enables promoters to manage and remotely control purchaser modifications and options within the framework of their off-plan apartments, thereby providing the purchaser with a customised experience.



    Proof of the new

    Purchasers of apartments can sometimes hesitate between new and existing properties.

      E-nergy supported us in a project management capacity across several eco-districts to shed some light on our energy strategy. Thanks to their intervention we have secured our community commitments (renewable energy rate, CO2 emissions) while simultaneously optimising the installations:
      – Budget managed by the inhabitant

      Yann Leblond
      Partner and Co-founder

      Fascinated by stone and architecture since my childhood, I started working in the real estate industry in the early 2000s. Contemporary real estate is no longer only valued by a rule of location or relationship of supply and demand, it must also meet energetic, environmental and societal imperatives. This new path must be accompanied by experts who guide decisions towards a good harmony between asset value / environmental concern / comfort of use.

      Benoît Ricard
      Partner and Co-founder

      Trained as an engineer, I have worked in the property sector since the end of the 90s. The technique is fascinating as it covers a broad range: construction, innovation and advancement. In the midst of a complex energy transition, this technique must be popularised for it to be understood and be at the service of decision support. This is what we do on a daily basis at E-nergy: provide a wide angle and instructive view as well as advising our clients on the implications of the city of the future.
