Top Lighting for Enhancing Daylighting Performance in Drawing Studios

Abstract

Daylighting strategies are one of the most common aspects of architecture, but their proper use was ignored by the designers during the implementation of the buildings which led to the lack of a good distribution of the natural lighting within the deep spaces. They find a lot of spaces have many windows and the absence of any external obstacles to entering the daylighting inside the space. But it has found some areas still dark, and this is not accepted in IES; Due to the availability of cheap electricity at the time, the main dependence on space lighting was achieved by using the non- regulated electricity which led to the rapid increase in For this purpose, this research paper aims at activating the use of lighting strategies in educational establishments, especially the drawing rooms, which needs to be equipped with regular lighting, and for long periods, to maintain the visual comfort of the application and rationalize the use of electricity using the techniques of the daylighting for the regular distribution of lighting. In chapter one, an emphasis was on the importance of daylight lighting and its relation to the regional climate and the most important systems used to provide daylighting into space while saving thermal comfort, especially in educational buildings and the extent of the relation of providing a good visual environment with student productivity have been reviewed with mentioning some of the educational buildings that have used top lighting systems.

In chapter two, the top daylighting Characteristics, types of daylighting, the most important systems, and unilateral or multilateral daylighting strategies that should be applied in the stage of the conceptual design of a building and show Types of Top lighting Shading Techniques.

In chapter three, show the definitions Daylighting Metric describe Parameters Base Case and follow Simulation Methodology from Simulation Inputs and Analysis of Software Simulation Tool and Design Variants, 3D Parametric Models, Weather Data, Occupancy Schedule and finally Simulation Outputs as a result to sDA (Spatial Day Light Autonomy) and ASE (annual sunlight exposure) for choose accepted case was closed to IES criteria

In chapter four, show the concept of designing shading technique and mention types of the shading systems to focused on shading techniques simulation methodology for treatment the chosen case to achieve the accepted criteria well light for visual comfort.
