| Summary: | The facade design of modern office buildings is dominated by glass which can increase sunlight penetration while increasing the thermal load of the building. In addition, direct sunlight can cause glare for the occupants. To be able to regulate the light coming into the room used internal shading, namely the blinds.
The angle parameters of the blades and the area covered by the blinds are varied so that there are forty-five combinations. Each combination is simulated with Honeybee software that can integrate light (DAYSIM) and energy simulation (Energy Plus). The results of the sensitivity analysis show that the three performance indicators are more sensitive to blade angle parameters compared to the area covered by blinds.
To determine the dynamic shading schedule, at each time step the most optimal combination of shade parameters is determined by the penalty function. There are two different dynamic shade schedules for each input quantity, namely incident radiation and sun elevation. |
