In a time when energy crises loom on the horizon, means for more efficient energy sources are being thoroughly researched. One such area for improvement is in the building sector with the implementation of double skin façades (DSF). With capabilities of relatively rapid and large changes in various aspects of itself, a DSF can respond dynamically to varying ambient conditions. Applying American Society of Heating, Refrigerating and Air-Condition Engineers, Inc (ASHRAE) standards to design a general building model with a standard HVAC system, a comparison can be drawn between different architectural configurations, both with and without DSFs, and a better understanding of how a DSF can affect heat transfer into a building could potentially influence future structural design decisions. Using CAD models, a flow analysis and rudimentary heat transfer can be conducted in a computational fluid dynamics (CFD) software, Fluent which can account factors such as wind speed as well as solar radiation. With the various design applications, the heat load of a building can be reduced by over 15%.
