Cover systems known as green roofs have the potential to retain rainwater and help reduce runoff. However, the characteristic considered in this work is the insulation capacity of this kind of coverage. To evaluate the spatial distribution of temperatures in an environment with light green roof, we proposed a new method for acquisition of series of climatological data and temperatures according to spatial and temporal approaches of dynamic climatology. Climatological data were provided by an automatic weather station and temperatures were collected in a test cell with light green roof. The spatial distribution of surface temperatures and internal air temperature （DBT） are based on the concepts of a climatic episode and typical experimental day from the study of the dynamic climatology. The results led to the conclusion that the light green roof has a balanced spatial distribution of the IST and of the internal air temperature （DBT）, i.e., without substantial variations over the day. The new methodology also showed the importance of specifying the location of the sensors and automatic weather station in experimental studies on the thermal behaviour of buildings.展开更多

The study is exploratory, descriptive, and qualitative type, such as a survey, developed through an adaptation of a relevant research, which involves the standardization of data collection instruments （questionnaires and interviews） applied directly to persons of a specific population, to assess knowledge management tools present in the University Hospital portals in the northeast region of Brazil. The results indicated that the resources from knowledge access were more prevalent than the others, ratifying the results found in research developed in Asian and North American Hospital portals.展开更多
