Comparison of energy consumption with regard to type and percentage of glazing, location and orientation in classroom spaces

Abstract

Much of the art of daylighting lies in the judicious placement of windows in relation to the interior, in order to achieve the desired levels of illumination and view. Studies have shown that the glazing size, location and type all impact the internal energy loads. Schools are incorporating technology in classrooms to transform learning. The expanded presence of technology in the classroom has also affected how classrooms are designed. This study tries to determine a glazing ratio for classroom spaces of the future in regards to energy consumption as a combined function of climatic conditions, orientation, glazing types and window location. A 35'x32' base classroom is simulated using the E-Quest software. Energy consumption for the base case is compared to models with variable orientation (north and south), type of glazing (double pane, low e and special glazing), glazing percentage of the total wall area (base taken with reference to the required daylight factor) and classroom with and without clerestory windows.
