4.3.3. Savings potential of various profiles for the different building
types
Savings potential varies depending on the building type. The reason is found in the profiles forming
the basis for EN 15232:
· Operation (heating, cooling, ventilation,.. in efficiency classes A, B, C, D)
· User (occupancy varies depending on building type)
Operation profiles in an office building
BAC efficiency class D
Efficiency class D represents a less beneficial case versus class C. Both temperature setpoints (for
heating and cooling) have the same value. In other words, there is no energy dead band. The HVAC
plant is operated 24 hours a day, although occupancy is only 11 hours.
