Análise do conforto térmico na obra de João Filgueiras Lima, Lelé: hospitais Sarah de Salvador e do Rio de Janeiro

Abstract

The design passive strategies reduces the use of air conditioning significantly and improve the users’ thermal comfort. This be illustrated through the Sarah network of hospitals designed by the architect João Filgueiras Lima, Lelé, whose solutions providing more pleasant environments and avoid the use of cooling mechanical systems. This paper aims to evaluate the thermal comfort of Sarah hospitals located in Salvador and Rio de Janeiro cities, through measurements on site of air temperature, air relative humidity and wind velocity. The results analyses are based on projects lectures, ASHRAE Standard 55/2004 and parameters acquired in the specialized literature. The results demonstrate the Lelé’s concern in incorporating the bioclimatic aspects in his projects. The measurements show that the midday period some Salvador hospital environments remain outside of comfort zone due to heat gain from coverage. However, the use of natural ventilation, allows a cooling effect during this period, improving the thermal conditions in internal spaces. In the case of Rio de Janeiro hospital, all environments are inside the comfort zone proposal by ASHRAE Standard 55.
