Proposta De Requalificação Da Iluminação Em Enfermarias: Estudo de Caso em um Hospital Público na Cidade de Barbalha, Ce

Abstract

Many luminotechnical projects in the hospital area are often limited to the minimum established by the norms. This can be understood by the lack of adherence to the quantitative aspects by designers, as well as in the norms. Lighting, besides the act of illuminating an environment, can bring benefits to hospitalized patients, and can contribute to the reduction of hospitalization days. One of these factors is through the knowledge of the human circadian cycle, also known as the biological clock. The circadian cycle is understood as an internal clock that dictates to the body how to live in an environment that changes daily. Sleeping and waking up, eating and fasting, and secreting hormones are just a few examples of circadian rhythms. And it is some of these circadian cycle functions that lighting can help with. For hospitalized patients, it is important that this is not interfered with in order to maintain metabolic activities. Thus, having a good luminotechnical planning that can have a good communication with the biological rhythms of the patient is necessary for his or her recovery. This paper analyzes the importance of artificial and natural lighting for the well-being of users in inpatient areas, specifically in wards, through a case study at Santo Antônio Hospital, located in the city of Barbalha, Ceará. The study verifies the deficiencies of the present lighting system, confirming that some criteria established by national and international standards are not met, compromising the spatial quality of the wards and the comfort of their patients
