Abstract
El-Dakahlia Governmental Headquarter is the central office building serving 5.5 million citizens in El-Dakahlia governorate in Egypt, and The public plaza around the building is the focus of Mansoura city urbanism. Despite The building importance, it faces many problems on its indoor environment and has a poor thermal performance. Natural ventilation is an effective method for enhancing indoor environmental quality in hot-arid climates with zero energy consumption. So, the building requires redesigning the entire spaces and façades according to the environmental aspects. This research evaluates different passive façade designs within a new special architectural design, by using digital simulation tools - CFD software and Ecotect - to reach affordable natural ventilation and hence thermal comfort. The evaluation method depends upon the perfect natural ventilation occurred and perfect solar gain control. It was found that, a double layer west, east and southeast façade, single one in north-west also creating indoor open space will achieve adequate natural ventilation and comfort spaces. This research aims to produce a concept of pilot renovation stands up on simulation process and green architecture standers to be generalized on other office and governmental buildings in Egypt.
