How can TD handle high floor-to-ceiling heights such as in lobbies?
To achieve a high ventilation and cooling effectiveness when the floor-to-ceiling height is high it is often better to let the supply air enter the room at low level (so called displacement ventilation). TermoDeck works very effectively when combined with Displacement Ventilation. The cooled supply air is getting warmer when passing the hollow cores in the slab, ensuring that the air entering a room at floor level will be only 1-3C different from the room temperature. Conventional systems have experienced problems with draughts when using displacement ventilation because of the high supply air flow needed (as the supply air shouldnt be below 17-18oC to avoid discomfort). There are several buildings with TermoDeck used together with displacement ventilation. In UK, for instance, there are over ten buildings, for example some theatres.
