This paper presents the results from a series of experimental activities and simulations focused on assessing the luminous environmental quality as well as the energy demand for lighting within healthcare buildings. The study was aimed at evaluating the level of visual performance and comfort as perceived within the various hospital spaces by the different categories of users who operate in them: patients, relatives, doctors, nurses and nursing aids. The research consisted of both a subjective and an objective in-the-field study, which was carried out in four hospitals in Turin and Asti (Piedmont, Italy), different for construction age, types of patients and offered services, daylight access and view out, architectural lay-out. The subjective study was based on a survey through questionnaires submitted to both patients/relatives and to the nursing staff, integrated by photometric measurements within sample rooms of different wards. For each ward, both the bedded area (bedrooms and living rooms), and the staff area (nurses/doctors’ offices, rooms where the nursing staff visit and manage patients’ medical records and prepare medications) were analyzed. As a first step within a more comprehensive work, the topic of lighting was addressed, due to its relevance for carrying out work tasks in safe conditions (particularly for the nursing staff) and for environmental quality perception and well-being for users. Illuminance levels on beds, work surfaces and VDT displays were measured, luminance maps of the visual scenes as perceived by users were recorded by means of an Image Luminance Measuring Device and users’ subjective appraisals were investigated through different questionnaires. Furthermore, the field analysis was integrated with simulations to estimate the associated energy demand for lighting and its reduction due to different lighting and blind control strategies.

Abstract

This paper presents the results from a series of experimental activities and simulations focused on assessing the luminous environmental quality as well as the energy demand for lighting within healthcare buildings. The study was aimed at evaluating the level of visual performance and comfort as perceived within the various hospital spaces by the different categories of users who operate in them: patients, relatives, doctors, nurses and nursing aids. The research consisted of both a subjective and an objective in-the-field study, which was carried out in four hospitals in Turin and Asti (Piedmont, Italy), different for construction age, types of patients and offered services, daylight access and view out, architectural lay-out. The subjective study was based on a survey through questionnaires submitted to both patients/relatives and to the nursing staff, integrated by photometric measurements within sample rooms of different wards. For each ward, both the bedded area (bedrooms and living rooms), and the staff area (nurses/doctors’ offices, rooms where the nursing staff visit and manage patients’ medical records and prepare medications) were analyzed. As a first step within a more comprehensive work, the topic of lighting was addressed, due to its relevance for carrying out work tasks in safe conditions (particularly for the nursing staff) and for environmental quality perception and well-being for users. Illuminance levels on beds, work surfaces and VDT displays were measured, luminance maps of the visual scenes as perceived by users were recorded by means of an Image Luminance Measuring Device and users’ subjective appraisals were investigated through different questionnaires. Furthermore, the field analysis was integrated with simulations to estimate the associated energy demand for lighting and its reduction due to different lighting and blind control strategies.
