Large windows with increased exposure to daylight have strong positive effects on the well-being of building occupants and can provide energy savings when appropriate glazing specifications are employed. The work evaluates the impact of different window sizes and glazing on heating and cooling energy needs in a hospital patient room, in order to investigate the energy savings achievable by adopting wider openings and to identify the most effective glazing types. Simulations have been conducted for different commercially available glazing systems. The authors analyzed the energy performance of a base case window with 25% Window-to-Wall Ratio (WWR) and of a wall-to-ceiling window with 77% WWR, in rooms facing the four different orientations and located in Bologna, Italy. Results show that the adoption of wider windows with appropriate glazing can lower the heating and cooling energy demand.
