Optimization of Daylighting Design Using Self-Shading Mechanism in Tropical School Classrooms with Bilateral Openings

Despite its potential, daylighting strategies in school classrooms in the tropical climate regions is little explored in the literature. The use of two-sided or bilateral daylight opening, as well as the self-shading mechanism using sloped walls, are currently seen as potential strategies to achieve good daylighting in tropical buildings.

A Daylight Assessment on Visual and Nonvisual Effects of Light Shelves: A Human-centered Simulation-based Approach

The contribution of daylight to a comfortable environment for occupants has been the subject of studies for years. Light shelves are known as daylight redirecting systems to enhance indoor daylight conditions. Although several research papers have focused on their daylight performance, there is a lack of studies on the performance of light shelves on circadian rhythm.

Automatic vs Manual Control Strategy for Window Blinds and Ceiling Lights: Consequences to Perceived Visual and Thermal Discomfort

A case study to evaluate the occupants' satisfaction in relation to two different control strategies (fully automatic and manual) for blind and ceiling lights use in cell offices was carried on in Trondheim, Norway. A group of 11 participants with varying age, gender, and ethnicity, used two test cells of a laboratory as a workspace primarily carrying out office tasks at a personal computer for a total of 19 calendar days.

Outdoor Investigation of High Concentrator Photovoltaic Under Uniform and Non-Uniform Illumination

This study was performed in outdoor conditions to quantify the level of influence on the electrical performance of the Multi-junction (MJ) solar cells. It was discovered that non-uniform illumination on the solar cell could reduce the MJ electrical output by more than 40%.

Phasor Method to Estimate Illuminances Due to Parallel Arrays of Light Sources

Direct horizontal illuminance along a calculation row due to two parallel arrays of large numbers of identical light sources behaves like a periodic signal with a sinusoidal pattern, which contains useful information for design purpose. This study aims to describe, verify, and discuss the theoretical concept on the superposition of direct horizontal illuminance from both arrays in such configurations, and how to extract the information using the phasor method.

Daylight Distribution Improvement Using Automated Prismatic Louvre

Louvre is a common type of shading devices and has been increasingly used in office buildings. Meanwhile, some reflective types of louvre have been used to provide shade and to redirect daylight deep into buildings interior simultaneously. Furthermore, daylighting systems have been recently engaged with automation control to improve their performance and increase their accuracy.

Acrylic Panels Applications as Building Materials and Daylighting Devices

Enormous studies have been conducted to enhance the daylighting utilization in buildings either by direct lighting techniques, lighting reflection systems, lighting transporting systems, or by light tracking systems. The current research aims at evaluating acrylic panels as a light transmitting medium and studying their possible applications to bring natural light to inner spaces due to the lack of researches on acrylic sheets.

Daylighting metrics: an approach to dynamic cubic illuminance

Advances in research work in the field of numerical analysis of daylight performance have generated in-depth knowledge on photometric measurements of daylight quality. Most dynamic metrics are based on illuminance, which is a two-dimensional concept insofar as it is concerned with the density of luminous flux incident at a point on a surface.

Improvement of Optical Performances Using the Hybrid CPV

Hybrid Concentrated Photovoltaics (HCPVs) are systems in which additional low-cost silicone solar cells are added to take advantage of the power generated by the diffuse radiation lost when using only multi-junction cells that work only with direct radiation. The work has been tested by simulating the performance of a hybrid CPV system composed of a Fresnel lens associated with a pyramid, multi junction cell as well as additional silicon solar cells.
