Low daylighting performance in hospitals(Case study Alomalem medical city –Khartoum)

Abstract

Many studies and researches proved that daylighting has positive effects on human’s Psychology, health and performance in addition to it’s role in improving indoor environment quality, energy saving and building’s sustainability. In hospitals daylighting is very important factor to create a good healing environment because daylighting contribute to patients’ outcomes such as shorter length of stay, reduced stress, increased patients satisfaction and other, but in Sudan, hospitals daylighting is a neglected issue although it’s important role in penitent’s health , staff performance and visitor impression , is a must. This research aims to improve performance of daylighting in hospitals in Sudan and investigate the reasons behind the low performance of daylight in hospitals. In order to achieve that, experimental method is used to assess the current situation in Almoalem medical city. The research concludes that the performance of daylighting in Almoalem hospital is signifcantly poor. That result from firstly design problems such as space’s design , orientation , materials and colours used inside spaces in addition to windows distribution and glass type. Secondly legalizations problems such as many hospitals are not designed as hospitals but they are converted later on to be hospitals without consideration to the health building requirements. Therefore, the research recommends giving more consideration for daylighting in design process from planning up to interior design, making daylighting legalization clearer and more effective in list of building’s organization. In addition to Further studies needs to be done to provide more data.
