In the construction of new buildings the combination of a radiant system and a heat recovery ventilation system is increasingly requested. This is because the systems integrate perfectly in buildings with high energy performance. On the one hand, they provide heat recovery from the air exchanged with the outside and on the other hand, they optimise consumption thanks to the possibility of supplying the radiant system with water at lower temperatures than other heating systems, thus optimising the efficiency of heat pumps or boilers of the latest generation.
Energy-using products account for a large proportion of the consumption of natural resources.
To limit consumption the European Union has issued directives and regulations such as the delegated regulation 1254/2014, which regulates the labelling of residential ventilation units to indicate their energy consumption.
The energy label allows the user to easily compare the energy efficiency of different products.
Unlike other electrical components, the energy classes on the labels for residential ventilation are determined by one parameter: specific energy consumption, or SEC.
This value shows the energy saving potential of the unit in kWh per m2 per year.
| SEC Class |
SEC [kWh/a·m2] |
| A+ (high efficiency) | SEC < -42 |
| A | -42 ≤ SEC < -34 |
| B | -34 ≤ SEC < -26 |
| C | -26 ≤ SEC < -23 |
| D | -23 ≤ SEC < -20 |
| E | -20 ≤ SEC < -10 |
| F | -10 ≤ SEC < 0 |
| G (minimum efficiency) | 0 ≤ SEC |
