Performance evaluation of dynamic methods of Visual comfort energy conservation using Natural and Artificial light

Abstract

This paper deals with the visual analysis for maintaining the visual comfort level, in the model room considered. The optimum position of blinds, to manage set point temperature of 24°C, as discussed in previous studies is investigated. For the set blind position, the illuminance inside the room is maintained at the prescribed value. The daylight integration into the interior is emphasized. The artificial light is switched ON or dimmed accordingly, to maintain the set-point illuminance level. The Energy consumption is calculated for different blind positions. The energy savings, hence obtained are investigated. The energy savings, hence obtained are investigated. This chapter also discusses the analysis of Natural and Artificial light. Visual comfort is the ability to position oneself within a building to see well enough to perform a task safely and easily. The visual comfort is achieved if the building has the right orientation of windows, with proper view, and not excessive daylight entry to cause glare. For visually comfortable environment using daylight autonomy techniques, a multi building design can ensure both the enhanced light and the aesthetic design. In these days proper stabilization between natural & electric lighting has been known as optimum under consideration of comfort, health & well being.
