3E is an international firm of renewable energy and energy performance optimisation experts and engineers. 3E designs zero-energy buildings and sites and carries out technical energy studies. Its goal is the gradual, effective and profitable deployment of energy systems which operate entirely on renewable energy.

3E implements economically and ecologically optimised projects. To do so, it relies on its unique knowledge in the simulation, energy resource analysis and integrated system design fields.

3E now has 15 employees specialised in building energy performance, the rational use of energy in construction and the use of renewable energies. They analyse buildings in their environmental context, notably via master plans and BREEAM and carbon footprint analyses.

The office also takes part in international research projects, primarily into new technologies for buildings and intelligent networks.
