What's a good ventilation strategy from an energy point of view?

Ventilation guarantees a sufficient air supply for users and combustion equipment, maintains inside air quality and reduces the probability of condensation or mould formation.

On the other side, ventilation can represent an important energy consumption. This is used by possible motors driving ventilators but mainly for heating and conditioning fresh air supply. To limit this energy loss, following approach should be useful:

• address pollution at the source
• airtight construction
• controlled ventilation
