In Italy, Germany and Denmark natural ventilation systems are used as the reference. In Norway it is a
mechanical exhaust air system. With the current trend to improve the air quality in working environments here
particularly in schools comes a need for considerably higher ventilation rates than before. Without changing the ventilation system this will result in higher thermal losses and thus higher heating needs/bills. A balanced
mechanical ventilation system with heat recovery of the exhaust air (MVHR) may improve this situation strongly.
