As part of its policy to combat global warming, the Department of Cantal is implementing the thermal renovation of its Simone VEIL University Campus. Building A concerned was built in 1970 and covers an area of 6,884.65 m2. The objective is to achieve the BBC Effinergie level of 40% savings compared to the reference standard and energy class B after work. The main thermal improvements concern both the building (external carpentry, insulation of floors and walls from the outside) and the technical installations (change of heating mode and installation of a ventilation solution).
