AQUILO Hybrid system

Integrated supply air diffuser
with thermal building mass connection

In combination with the A11 or SPECTRA M radiant heating and cooling ceiling systems, AQUILO forms a high-performance climate ceiling system with integrated supply air and superior sound absorption values. The integrated supply air element provides controlled air distribution. At the same time, the supply air jet on the rear side of the ceiling panel supports convective heat transfer and therefore the heating and cooling capacity in the room.

In combination with the A11-C and SPECTRA M-C closed ceiling systems, AQUILO additionally integrates the building mass into the overall thermal concept based on the thermo-active building system principle. The building mass can be used as an additional thermal storage mass.

With the A11-S radiant ceiling sail, the Convector Wings developed specifically to increase capacity can also be used.

Basis for assessment

Cooling capacity

The cooling capacity corresponds to the amount of energy per second removed from the room via heat radiation and convection. It is determined in accredited climate laboratories in accordance with SN EN 14240.

For comparison: the heat emitted by a person in an office via radiation and convection is approx. 70 – 80 W; the heat emitted by a laptop is approx. 20 – 50 W.

Heating capacity

The heating capacity corresponds to the energy per second added to the room via heat radiation and convection. It is determined in accredited climate laboratories in accordance with SN EN 14037.

For comparison: The heat output of a person in an office via radiation and convection is approx. 70 – 80 W, whilst that of a laptop is approx. 20 – 50 W.

Sound absorption

As the largest unobstructed surface in a room, the ceiling is particularly well suited to sound absorption. The sound absorption class is determined in accordance with EN ISO 11654, based on measurements carried out in accordance with EN ISO 354 in accredited laboratories.

It serves as a parameter for acoustic designers to calculate the effect of a product on a room’s reverberation time.

Carbon footprint

The carbon footprint describes the greenhouse gas emissions associated with a product. These emissions are expressed as CO₂ equivalents. The life cycle stages considered are specified in the respective Environmental Product Declaration and its defined system boundaries.

An Environmental Product Declaration (EPD) transparently presents various environmental impacts of a product based on a life cycle assessment. The calculation is carried out in accordance with the standards and methodological requirements specified in the EPD. Where stated, the EPD is verified by an independent third party.
