A real company culture

At Gesys, we enjoy working together. We always take the time to greet each other and chat or swap ideas over a coffee. This cohesion is what cements our team together. The human dimension lies at the heart of our DNA and is reflected in our values.

Team spirit: our team spirit is a result of our employees listening to each other and sharing ambitions. Each employee is an expert, a specialist in his or her own field. But talent alone is not enough. That is why every future employee goes through a selective recruitment process in order to guarantee not only the success of your projects, but also cohesion within the team.

Reactivity: faced with your requirements and especially the environmental challenges, we need to be able to adapt and offer you a global and tailored solution. Thanks to the agility of our teams, we are able to design innovative solutions to your specific issues.

Respect of our undertakings: Results-oriented, we strive to bring your ideas to life. To do that, we undertake to respect deadlines, budgets and technical constraints. Our professionalism is reflected in the strict demands we place upon ourselves, our expertise and the search for excellence.

Acting to protect the environment!

We favour projects which offer significant environmental added value allowing for the development of sustainable construction and an industry which respects the environment. Sustainable development is integrated into all our projects. We therefore support you in your sustainable development and environmental quality approaches:

  • Building Energy Audits / Energy Performance Diagnosis
  • Regulatory Thermal Performance Calculation / Dynamic Thermal Simulation / Dynamic Energy Simulation
  • Assistance with the Design and Creation of Certified Buildings: B.B.C. / Effinergie+ / ADEME / T.H.P.E. / H.Q.E. / BREEAM / LEED

We can work with you on the implementation of new technologies:

  • Wind-powered / Geothermal / Photovoltaic / Solar heating / Energy recovery
  • Optimisation of energy consumption: LED lighting, radiant ceiling panels, direct current, cooling unit, magnetic levitation terminals, etc.

Integrating the human dimension into all our projects: wellbeing, comfort and health in the workplace

Offering a comfortable and safe working environment equipped with cutting edge technologies is a major challenge in the construction market. All new or renovated buildings must therefore undergo a double transition: the energy transition and the digital transition.

At Gesys, we take into account the ecological, digital and human dimension in all the projects we work on. Consequently, we plan each building ensuring that the comfort and safety of its occupants lie at the heart of the design. To do this, we also integrate the sustainability of the construction and the connectivity of the buildings. The infrastructure is therefore open and evolutive. The key consideration: the comfort, wellbeing and health of all your employees!
