Buildings need year round ventilation. In traditional ventilation systems the conditioned inside air is lost when exhausted externally and new unconditioned air is brought into the building. This results in large amounts of air being heated up or cooled down over and above the actual load of the air conditioning system and leads to a substantial waste of energy.

The Daikin system however, automatically balances outside and inside temperature and humidity enabling the recovery of heat/cold with significant savings in running costs.
