The villa, a detached family home on two floors, was built using pre-cast concrete panels - a Modern Method of Construction that is widely used across the Gulf Region and in many other countries. Interlocking assemblies of type permeodynamic insulation cells were fitted internally over the available wall area and sealed in place using an independent, self-supporting gypsum board lining system that contained and protected the cells. As the name suggests, permeodynamic insulation permits the flow of air through the cells to facilitate the recovery of building fabric heat or, as in the present case, coolth loss to ventilation air. In operation, ventilation air has to flow through the rain screen cladding using an inlet vent into an air cavity, then through the permeodynamic insulation into an internal air cavity, and thereafter thro...

Dynamic facade, using Dynamic Insulation (DI), is an energy-efficient method of supplying pre-tempered filtered ventilation air to a building through an air-permeable dynamically insulated envelope or facade. One of the important features of DI is that it effectively decouples ventilation rate from energy use. In theory, it should work well with all buildings, including homes, schools, offices and sports facilities where high occupancy is the norm. This paper investigates the use of DI in a building facade for zone local insulation and ventilation. The savings in energy and CO 2 reduction are quantified against existing standards in the Gulf Region. The results show that DI can provide tempered fresh air, raise energy efficiency and reduce air conditioning energy demand without co...
