To avoid the buildup of harmful pollutants, buildings are ventilated with new outside air.
This air must be heated in the winter and cooled in the summer which can represent over 30% of the energy consumed by the building.
Nedlaw Living Wall Biofilters supplied good clean air at a fraction of traditional systems.
Since the air entering the Nedlaw Living Wall Biofilter is already at the right temperature, this energy expense can be avoided.
Clean air can be supplied to the occupants for as little as 24 watts per person (less if the system is naturally lit).
