“…The authors conclude that smaller or wide rooms result in greater energy savings in lighting and the ideal window area tends to be higher in low thermal load orientations. Another notable example can be found in the research of Li et al [10], who developed a calculation procedure relying on the daylight coefficient concept and confirming the results using the Radiance program. In this study, the authors create a method based on multiple tables and charts for establishing illuminance.…”

Abstract-The aim of this research is to quantify the daylight autonomy and the useful daylight illuminance produced inside a room for different models of windows, and to conduct an analysis of the results obtained. The shape, size and position of the window are variable, as is the reflectance of the inner surfaces of the room. A total of 28 simulations are provided by the lighting simulation program DaySim 3.2. After trials it was concluded that the daylight autonomy is directly proportional to the glass surface in the back of the room, while its influence in the zone near the faç ade is negligible. However, the energy saving does not depend on the window shape. It is also concluded that the windows in the upper position allow higher luminance at the back of the room than those in centered locations.Index Terms-Daylight autonomy, energy saving, useful daylight illuminance, window.

“…Hence, the cooling requirement of the building decreases due to the provision of natural daylight. The daylight coefficient concept offers a more effective way of computing indoor daylight illuminance in lux [3]. Similarly, Joshi et al [4] gave a brief review on different mathematical models for the estimation of daylight in buildings.…”

“…Although many studies report the benefits of daylighting on health, environment and energy conservation, the daylighting in buildings are still in their preliminary stages throughout the world (Kurian 2006;Li et al 2006;Krarti et al 2005). The lack of information on the suitability of daylighting, system design, and its potential to save energy is the main reason for such an unenthusiastic response to daylighting designs (Li and Tsang 2008;Rubinstein et al 1990).…”

Prospective techniques of effective daylight harvesting in commercial buildings by employing window glazing, dynamic shading devices and dimming control—a literature review

Over a few decades, daylighting has been perceived to possess good potential for energy conservation. In this perspective, there have been significant advances in research methodologies and technologies for optimizing energy consumption through daylight harvesting in commercial buildings. In light of this, a thorough understanding of the application of available technology is very important for daylighting practices for building energy management. The objective of this paper is to examine the status of published research on three key building parameters: window glazing area, dynamic shading devices, and daylighting controls playing a rule on energy conservation. This article may serve as a coherent literature survey that would provide better understanding of the subjacent issues and possibly rejuvenate research interest in this immensely potential field of energy engineering.
