Uso de dispositivo de control solar en aulas: impacto en la simulación dinámica de la iluminación natural


Ambient. constr.




The use of daylighting in educational spaces contributes from different perspectives such as energy, health and comfort. However it requires careful planning during design. The aim of this study is to determine the impact of solar control system in two classrooms (north-south orientation and east-west orientation), typical of regional educational buildings, through a dynamic daylight predictive method. The methodology adopted was: (a) physical and photometric survey in situ; (b) simulation and analysis of dynamic daylight metrics and supplemental artificial lighting; and (c) evaluation of the impact of the solar control system (textile curtain). The results indicated the empowerment of daylight in the north and south facing classroom with high annual probability of glare, something that is reversed with the proper use of the proposed solar control device (SCD). Also, this SCD increases daylight availability (DAv= 12%) and reduces artificial lighting consumption, compared to east-west orientation. From this new approach, further significant reductions in electricity consumption (lighting) in day-use buildings are seeked, not only by adding complementary artificial lighting systems but also by using solar control system strategies in pursuit of user comfort.
