Full-scale evaluation of energy use and emissions reduction of a dynamic breathing building.

The U-Value of a dynamic breathing wall or roof incorporating the Energy flo™ cell decreases to near-zero as the air flow into the building is increased, allowing the building to be ventilated at higher levels than would otherwise be possible while significantly reducing energy consumption for space heating or cooling and associated emissions. Combined with filtration of incoming air, this means that healthy indoor environments are sustainable even in the polluted urban environment of a large city such London or Rome. The present paper presents early results of performance prediction relating to a real building, with and without mechanical ventilation heat recovery (MVHR) to illustrate the analysis methods used, the benefits achievable and provide a glimpse of future developments of this increasingly important technology.
