The effect of façade design on lighting energy consumption in offices: A case study in turin, Italy

Energy efficient design strategies should be finalised in the early stages of the building design process. Running costs can be reduced and the occupants' comfort and therefore productivity can increase. Evaluations of different façade systems should be carried out during the design stage in terms of energy demand in order to optimize the project. These evaluations need building simulations predicting the energy consumption. The present work covers a proposed approach to design the façade system and a case study to give an example of application, which is carried out by DAYSIM simulations. Such an approach would enable the design of an optimum façade system providing the visual comfort conditions and reducing electric energy consumption.
