5. Building conception: Reduction of the space heat requirement Installation of a thermic protection insulating glazing in the restaurant as well as an internal insulation in the bar and guest area. Improvement of the room air Source ventilation: the fresh preheated supply air expands within the base range into the guest area, continues to warm up by internal heat loads and presses up used air into the air exhaust duct. > best air conditions with optimized change of air Reduction of the ventilation losses by ventilation heat recovery in the bar with a recuperation grade of 95 %. Reduction of the ventilation losses in the kitchen by use of ventilation equipment with direct admission of fresh air into the exhaust air caps: > optimal kitchen ventilation with smallest losses of energy over the exhaust air.
