Investigating the control strategies for Breathing Walls during summer: a dynamic simulation study

The paper aims at studying different strategies for the optimal operation of Breathing Walls during summer. investigation is carried out by performing dynamic simulations on a case study. To this purpose, transient Finite-Difference numerical model Wall components, previously developed in Matlab and validated Authors, coupled with TRNSYS. study consists an office room located Milan, Italy, provided Air Conditioning Mechanical Ventilation air permeable wall. Forcing exhaust from indoor environment across has better performances compared to forcing supply outside Yet modest energy savings are found traditional impermeable use wall, as high level insulation already minimises heat gains through opaque envelope.
