4. Conclusion

Thermal simulation is therefore a key energy performance tool. It's a reliable tool, and its ergonomics are improving with each new version of the software.

These software programs are very precise and require a large number of assumptions to be entered in order to be reliable. This is where vigilance is called for. Indeed, in addition to the necessary rigor, the range of technical skills required to carry out a calculation must be very broad, including the calculation of thermal bridges and the thermal resistance values of joinery, and therefore precise knowledge of the building. But it also requires in-depth knowledge of energy production, regulation, emission and distribution systems.

Today, relatively few design offices have this know-how, so operators need to upgrade their skills. Several years' use of this type of tool is necessary...
