Modern domestic ventilation systems: energy-efficiency and comfort at home

New or renovated buildings are practically air-tight and permit only a minimum natural air-exchange. For this reason, the German Energy Saving Directive (EnEv) requires ‘that minimum air exchange is ensured for the purposes of health and for heating’ – and that this should not require specific intervention by the resident. Modern domestic ventilation systems provide the means to achieve this in a way that is safe, energy-efficient and convenient. They ensure a healthy indoor environment and prevent humidity and mould damage.

What is more, systems with heat-recovery and demand-based controls are also very energy saving. Heat recovery prevents heat being thrown, literally, out of the window, while demand-based controls enable automatic regulations of the system by means of CO2, humidity, toxic fume sensors. In addition, modern systems can interpret and utilise weather forecasts autonomously, they can be controlled by smartphone from any location and communicate with the other building technology components as part of the Smart Home concept.

Since the beginning of the year a new EU energy label for domestic ventilation units provides for greater market transparency. Amongst other things, you can see how energy efficient a particular unit is. The advice of an industry professional should always be sought when determining which type of domestic ventilation system – there is a basic differentiation between centralised and decentralised systems – makes most sense for a specific building project and ideally this should include preparation of a ventilation concept in accordance with DIN1946-6.
