In the highly populated urban areas, there is the obstruction to the daylight by high rise
buildings which minimize the light level in the deeper and inside the lower floors. The usage
of natural energy in commercial and non-commercial building leads in minimizes lighting,
heating and the cooling loads. A novel approach is to introduce the advanced daylighting
systems and strategies. It effectively reduces building’s electricity consumption and improves
the quality of light indoors. Multiple functions served by daylighting systems using various
strategies, e.g. redirecting/deflecting the direct sunlight which helps in illuminating deep dark
spaces and the usage of controlled shading devices results in heat control. The objective of
the innovative daylighting systems (IDS) is to deliver the desired levels of illuminance in
deep-plan and high rise buildings where conventional fenestration fails to illuminates the
target areas. This study reviews the various existing systems and analytical approach used to
design IDS. An overview on the various daylighting systems with division into the main
principle, sketches and brief descriptions of elements helps up to an extent to choose the
appropriate daylighting system for the specific weather conditions and Location.

Bringing sun light into deep area of office or residential house rooms with simple arrangement of basic windows or sky facing windows is unattainable. To solve this problem light transport framework are important to bring sun light into the profound centres of structures. The main motive of this paper is to upgrade the performance of light transporting media (Horizontal transporting system) and Laser cut panel (LCP) as collector by simulation and study the performance of the various types of LCPs in which cuts are to be made on different angles(θ) i.e. 0°,5°,7°,8° and compare the performance of various LCPs of acrylic for South and East façade of the building in CSIO Chandigarh. It is cleared from the simulation that LCPs are location specific and its performance is depending upon the angle of cut (θ), aspect ratio(A), Refractive index.Keywords

A Fresnel lens is designed for redirecting the light for further use. Fresnel lens have short focal length, less volume, large acceptance and higher efficiency as compared to ordinary lenses.It is designed for area focus to achieve uniform illumination and less temperature at entrance of optical fiber bundle. The Fresnel lensis made up of polymethyl methacrylate (PMMA). It is a compilation of number of small square blocks, whereeach block is uniquely designed.Their ray trajectory is analyzed by using Trace-Pro software.Keywords

The utilization of sun light is exceptionally helpful in office structures and residential building because energy utilization can be decreased and working conditions can be improved. It also influences human beings wellbeing and profitability. In any case, bringing sun light into deep area of office or residential house rooms with simple arrangement of basic windows or sky facing windows is unattainable. To solve this problem light transport framework are important to bring sun light into the profound centres of structures. This paper describes the method for transporting sunlight to deeper areas of building structures. The main motive of this paper is to upgrade the performance of light transporting pipe by simulating individual component as well as whole product and minimizing transmission losses of light. In this paper the daylight is transported through horizontal mirror light pipe (MLP) into darker areas of the structure. Here Laser cut panel (LCP) of acrylic material is used for collection of light.Keywords
