Enhancing natural ventilation in patients’ wards in a Belgian hospital by integrating some ventilation concepts from vernacular architecture
Recently, passive techniques have received a considerable attention in our modern buildings as a response to energy consumption, global warming and world ambition towards energy efficient buildings. Passive ventilation did not share a big ratio of interest due to several reasons such as the problem of natural ventilation fluctuations and the uncertainty of ambient weather conditions. It is much easier to use current mechanical ventilation systems especially in hospitals to achieve constant and acceptable results in terms of thermal comfort and indoor air quality. Although, not all hospital spaces need intensive control and could form a big ratio of hospital built area such as patients wards. This study is a result of two previous researches regarding natural ventilation in vernacular hospitals and two modern ones in Jordan and Belgium. It tries to study the feasibility to integrate some of previous passive techniques in a typical patient ward in a Belgian hospital using CFD tool. Historical techniques will be simplified to integrate such techniques in current baseline model. The results of modified models will be compared with baseline model concerning ventilation performance. The results will give a perspective regarding natural ventilation feasibility in patients’ wards and whether it is possible to enhance this renewable source to be integrated with current HVAC systems. In addition, it will spot the light on the threats that could appear regarding natural ventilation.
