Resumo: Natural ventilation as a part of a buildinǵs function that has a strong effect on human comfort. The reduction of natural ventilation and infiltration, as a part of the ventilation system in the old existing buildings, due to intervention actions, have been causing a reduction in indoor air quality and an increment of relative humidity levels in the indoor environment. Providing optimal indoor condition is not only related to the renewal of the air but also with its distribution. Hence airflow patterns in historical buildings influence interior comfort conditions. The aim of this work is to assess the effectiveness of the existing natural ventilation system in the old and historical buildings by different natural ventilation strategies. To achieve the proposed objective, the research was developed resorting to in-situ measurements and simulation methods The simulation was performed with the Design-Builder software and the main goal was answering to the following question: - What are the existing conditions of the building in concern of the airflow circulation and distribution? The in-situ measurements were performed using Blower Door Test method in order to determine the existing building airtightness. Based on the obtained results for each building the intention is answering the following question: - Due to the limitation of the historical urban areas, which natural ventilation strategy is more effective? The results of this research can be interesting for architects, engineers, and people, who are working on intervention and renovation of old existing buildings.
