daylighting systems • redirecting daylight to under-lit zones • improving daylighting for task illumination • improving visual comfort and glare control • achieving solar shading and thermal control
02.daylight+lighting 1(23) introduction There are three major functions of daylighting systems for buildings: • to provide solar shading • to provide protection from glare; and • to redirect daylight. Daylighting and the impact of daylighting on the heating and cooling of buildings has a direct relationship to energy use and associated carbon emissions. Good daylighting design requires a balance between competing elements in façade and electric lighting systems; to find the optimum between a daylighting system and the control of heat input and unwanted glare. Daylighting systems serving multiple functions with a mix of strategies (e.g. the redirection of direct sunlight and the use of controlled shading devices), may be much more economical than using photovoltaic electricity.
