The global issue of energy consumption in buildings is of great importance.In general,healthcare buildings are among the most energy-intensive categories of structures.The majority of hospital space is devoted to patient accommodations,which require a substantial quantity of energy to maintain climate control through heating and ventilation.The external walls of patientrooms are the most critical component of the exterior surfaces of these buildings in order to reduce energy consumption.The provision of daylight and the ability to view the outside can substantially contribute to the healing process,as well as the reduction of suffering and the duration of hospital stays.Contemporary structures are becoming more prevalent with fully glazed facades. Further,they are desired for hospitals where it is believed that more connected to external views will improve the health and wellbeing of patients.Nevertheless,the utilization of wide windows may occasionally result in a negative impact on the energy consumption of a building.This study aimed to put a proposed strategy to improve energy performance in patientroom by,integrate intelligentglazing and shading devices.Allowing the window to remain more hours in aclearer state to achieve the balance of reduction of energy consumption and achievement of proper daylight distribution in patientroom.To test this,intelligent glazing material(AGT_T)was identified and modelled with horizontal shading device.A typical patientroom located in emergency hospital in KafrElsheikh,Egypt with asouthern orientation and fully glazed southern wall was investigated using design builder and energyplus software to make the simulation.The results showed that reduction of energy consumption of applied AGT_Tglass and the horizontal shading devices reached to15.9%as compared to existing state
