2018Abstract
In recent years active facades have acquired greater importance given their capacity to improve the energy efficiency of buildings. One such type is the so-called Active Transparent Facade (ATF). A 3D numerical model based on computational fluid dynamics (CFD) and the Finite Element Method (FEM) has been generated to simulate the thermal performance of buildings equipped with this type of facade. This model is introduced for general application and allows the design parameters to be adapted for this system. The case study of Le Corbusier's proposal for the City of Refuge in Paris, the clearest example of previous use of an ATF is examined. In addition, a proposal is presented for the energy improvement of Le Corbusier's original solution. In order to do so, the conditions for the supply of air into the ATF cavity and in the mechanical ventilation system are assessed to guarantee comfort conditions.
