We all know how important it is to efficiently ventilate an underground garage to create a healthy and safe indoor climate. In today's blog post we would like to present an innovative solution: An underground garage ventilation system implemented with Renson's L.050HF louvre and a green roof canopy. This construction combines functionality with aesthetics and is an example of modern building craftsmanship.

Before we turn to the overall concept, let's take a closer look at the technical data of the L.050HF slat:

- **Material**: Extruded Aluminum
- **Profile height**: 50.0 mm
- **Profile depth**: 41.0 mm
- **Overlap**: 50.0 mm
- **Average slat inclination**: 51°.
- **Moment of inertia**: Iy = 45.058 mm⁴ (strong axis line); Iz = 941 mm⁴
- **Coefficient of friction**: Cfy: 1.21 (horizontal), Cfz: 0.85 (vertical)
- **Free cross section**: Optical 70%, physical 60%
- **Drag coefficient (K-factor)**: 8.03  

Thanks to the constructive design and vertical (lateral) air supply, the functionality of the underlying ventilation system remains guaranteed even in case of heavy foliage or snowfall

The roof hood system is intended for later greening. This integrates the underground car park ventilation system visually very nicely into the surrounding landscape.

The design effectively prevents entry into the facility and associated fall hazards.

The design minimizes maintenance and the need to remove weather influences such as snow and leaves. This leads to a reduction in operating costs in the long term.

The combination of Renson's L.050HF louvre with a justified roof canopy system provides a versatile, efficient and aesthetically pleasing solution for venting underground garages. It is a prime example of modern engineering and shows how functionality, safety and aesthetics can be combined in one system.
