LIGHTING SIMULATION OF UV-C RADIATION IN HOSPITAL WARDS: ANALYSIS OF CRITICAL SURFACES AS A FUNCTION OF CONSTRUCTION MATERIALS AND ROOM GEOMETRY
Abstract
UV-C lighting is increasingly occupying a significant space in research aimed at disinfecting environments, including hospitals. The relationship between construction materials and the correct volumetric layout of the hospital environment shows that small updates in studies like this can generate a relevant impact. This work aims to perform a simulation of UV-C lighting using the Dialux Evo software, in which, by inserting data from specific UV-C spectrum luminaires, maps, graphs, and data are generated from which it becomes possible to compose analyses of the environment, comparing the physical characteristics of materials such as Degree of Reflection and Mirroring and their contribution to the effectiveness of UV-C technology as an actinic agent. The choice of the best characteristics of the materials in the environment, as well as their composition in general, is not the focus of this work; it serves as a basis for data insertion for its composition. This research suggests volumetric adjustments that have shown an important relationship with a better distribution of irradiation. It was necessary to adjust the units, adapting the software characteristics that provide data in Lux units and correlate it to Irradiance in mW/m². Through the data collected with the simulation, it was possible to identify the necessary exposure time for germicidal lighting in up to 1 minute and 4 seconds.
