Rosvalla A-hall
Ceiling height
13 m to the lamp rigs. Above the lamps there is more space, but very unforgiving with lots of wires. A newly added (summer 2023) lighting structure descends below the lamps. The available free airspace is now up to 11,5 m.
Ventilation
The air is very good. They usually shut down the ventilation the nigh before we come here, and the air is typically very still, with no significant cold/sinking areas.
