Abstract

In this work the application of a building dynamic simulation in the development of horizontal shading device passive solution applied in an university canteen is studied. The building dynamic simulation, that simulates simultaneously buildings or groups of buildings, with complex topologies, in transient conditions, considers the solar radiation, the HVAC system, glass radiative proprieties, radiative heat exchanges, thermal solutions, occupants’ comfort and air quality, and others. In the horizontal shading devices passive solutions the numerical model, using a sun trajectory and window position, developed efficient external shading devices. The canteen considers three levels and is divided in 37 spaces. In the simulation, 100 transparent surfaces and 773 opaque surfaces are considered. Special attention is given in the students’ main canteen, professors’ main canteen and university bar. The simulation is made in summer conditions. A simulation without and with horizontal shading devices and without and with HVAC system on, controlled by PMV index, is considered. In the simulation, the occupation and the ventilation are considered. In accordance with the obtained results the horizontal shading derives reduce the interval air temperature and improve slightly the thermal comfort level that the occupants are subjected
