The development of sustainable projects involves many parameters, including the building’s shell and energy production systems.

These are interdependent: for example, the presence of external blinds reduces overheating, but will increase winter heating requirements and lighting needs unless their management is not optimised.

A dynamic simulation enables to analyse and to assess the energy performance, using a zone classification based on the orientation, use and occupancy of the rooms. This enables the building shell and systems to be optimised.
