This paper investigates a modular breathing wall cladding panel for commercial buildings and office blocks in polluted urban environments. Such panels enable the building envelope to act as an efficient heat exchanger, with reductions in operational energy achieved by using conduction heat loss to pre-heat ventilation air. The panels also act as highly efficient, maintenance-free filters of airborne particulates down to sub-micron scale for the life of the building, with similar filtration performance anticipated for biological and chemical filtration.

The result is a revolution in building technology that couples the external and built environments to save energy and provide clean ventilation air, filtered to HEPA levels, to occupants 24 hours a day, 365 days a year for life. Instead of adding pollution, it is possible for buildings in future to clean-up their surrounding urban environments.
