ABSTRACT: Shared hospitalization rooms (DHR) demand high levels of natural lighting and a proper visual comfort since daylight provides benefits to the health of a patient. The aim of this study is to establish guidelines for the use of passive design strategies (PDS) with daylight in (DHR), in a cold, semi -humid climate. The first stage defined the factors that have certain influence in the patients” visual comfort, the recommended levels for these factors, and its evaluation metrics. An explanatory methodology was applied on the second stage through a case study, in which simulation tools were used as instruments to assess the DHR involved in it. The third stage consisted on proposing (PDS) to the study case, which then were evaluated through simulation tools. Radiance software was used as algorithm engine, and programs as Daysim, Evalglare, and Ecotect were applied for data visualization. Through the creation of the integration diagram for lighting performance indicators for HOSPITALS, four PDS proximate to the expected optimal outcomes were found. Being the intermediate horizontal Iedges with an internal penetration length of 0.8om, an external penetration of 0.8om, and 0.4om for the floor -screed clearance height of 2.4om and 2.7m, the ones that presented a better performance as strategies of daylight catchment and preventing glare. The conclusion corresponding to this study is that due the varied weather conditions and the unidirectional lighting of the space, the design of the façade must consider the window’s dimension and position, and the strategies for light catchment consistent with the place.
