The present study aims at accentuating the use of computational modeling techniques towards significantly improving the effectiveness of daylighting control on energy and cost savings for historic office buildings.
The use of daylight-linked controls (DLCs) can be a valuable design strategy to improve lighting conditions of indoor environment and to obtain considerable energy savings.
When employing windows in modern buildings, numerous physical aspects need to be considered such as visual contact between interior and exterior, use of daylight, optimizing and controlling solar energy gains, minimizing thermal losses, optimizing thermal comfort, noise protection, air and driving rain tightness, and fire safety.
Energy savings from the use of daylighting in commercial buildings is best realized through the installation of reliable photoelectric lighting controls that dim electric lights when sufficient daylight is available to provide adequate background and/or task illumination.
The use of daylighting in buildings and architecture is not new.
The rational use of daylight through tools such as photoelectric lighting controls can effectively reduce buildings' electricity consumption and the related pollutants and greenhouse gas emissions.
The perfect control of shading devices, particularly venetian blinds can significantly improve the rational use of daylight in buildings and provide enhanced visual comfort for occupants while saving the electricity that would be used for artificial lighting.
Thus, the methods of achieving adequate indoor lighting conditions, by making use of daylight to save energy, while still maintaining other indoor conditions at an acceptable level, and the corresponding control algorithms, have lately become the subject of considerable attention.
The use of daylight in buildings to save energy while providing satisfactory environmental comfort has increased.
Daylight saving time (DST) is a change in standard time with the purpose of making better use of daylight.
