INCIDENCIA DE CONSIDERAR MOBILIARIO Y OCUPANTES EN LAS MÉTRICAS DE ILUMINACIÓN NATURAL

Abstract

Daylight analysis is undergoing rapid development thanks to computational tools that simplify their implementation. Dynamic simulations consider the variability of the sky and consequently there is intensive research into the representativeness of climate files. Something similar happens with the metrics with which the quality of the lighting environment is studied that, including human factors, are subject to permanent refinement. However, it is still a common practice to simulate empty rooms despite the fact that in an inhabited space there are always furniture, objects and at least one person inside. This work explores the incidence of the human factor in the lighting simulation output, with the aim of knowing how much the illuminance results can vary if the light obstructions and absorptions originated by furniture and people are also modeled. The Grasshopper platform and the Honeybee plugin were used to make parametric lighting simulations considering: a) several furniture layouts and b) changes in the position and posture of people. A typical room in an apartment building was studied and the results of simulating the same room completely empty were used as the Baseline. It is concluded by calculating the variability of the results when the illuminance simulations include furniture and the human body and recommendations are also made about which furniture should be modelled according to the region of the room in which they are located.
