Musée d'Art Moderne Grand-Duc Jean, Luxembourg

We would like to show you some parts of this building where the air distribution systems are most unusual.

“Grand Hall”
In the “Grand Hall” the supply air is delivered via special nozzles, which are arranged in line, both in the parapet area and in the upper area beneath the glazed roof (Fig. 2).
Alternating with air supply, the extraction of return air from the upper hall area occurs via a grille. At ground level a small part of the return air is extracted via the corners of the parapet, most of it being extracted via the lower floor at garden level.

“Jardin d’Hiver” (Winter Garden)
Most of the supply air is discharged in a linear way via jet nozzles positioned in the parapet area beneath the glazed roof (Fig. 3). In the lower zone the supply air is delivered by displacement air outlets arranged in the parapet area and at plant tubs.
The cooling and heating requirements are partly covered by floor cooling and heating surfaces respectively.
The return air enters the void between the natural stone covering and the reinforced concrete wall via a slot positioned below the glazed roof, and is then extracted.

Sun barrier and elements for cooling, heating and sound attenuation for the “Grand Hall”
The “Grand Hall” has a floor area of approx. 400 m² and a glazed roof area of more than 1200 m². External sunshades were not allowed by the architects of the building, I.M. Pei and Georges Reuter. A system solution was sought for providing heating and compensation for cold radiation in winter, and cooling and protection from the sun in summer, while acting as a sound attenuator.
The system applied consists of special elements fitted with a square-pipe frame and welded round pipes with water flowing through; they provide heating in winter and cooling in summer and perform the other functions required.

Auditorium at garden level
Supply air is delivered to the auditorium via a pressurized floor fitted with step displacement outlets under the seat rows as well as via linear induction outlets in the rear stage area. The return air is extracted in the perimeter zone via the ceiling void.

On this project KRANTZ KOMPONENTEN supplied:

• jet nozzles, type DW-N2, for several exhibition rooms and the winter garden
• induction outlets, type IN-N-6, for the exhibition room on the first floor
• adjustable induction outlets, type IN-V2, for the auditorium
• step displacement outlets, type Q-SL, for the auditorium.
