New day lighting systems such as the light pipe, light shelf, mirrored louvres and prismatic glazing have two main objectives: to bring daylight deeper into a space, and to control and distribute direct sunlight so that this can be used as an effective working illuminant. While a large number of devices has been proposed, little has been done to show rigorously whether they do in fact save energy or improve the internal environment. This paper describes the available systems and gives initial… 

A Review of Light Shelf Designs for Daylit Environments

A review of the research realized in the last three decades concerning light shelves together with their associated implications in a building’s daylight performance as well as in its energy balance in a few cases is reviewed.

Classification of indoor daylight enhancement systems

In a dense urban environment, sky obstruction caused by high rise buildings causes minimal daylighting for interiors on lower floors and in deep interior spaces. Innovative daylighting systems can be

Daylight coefficients for practical computation of internal illuminances

The interface between the sky modelling technique and simulation of internal reflection, and the modelling of blinds and innovative daylighting systems are described and the practical implementation of such a program to calculate year-round internal illuminances is outlined.

Study and Analysis of Parameters Affecting Tubular Daylighting Device

Renewable energy resources are clean and nearly everlasting in nature. These days, daylighting using renewable energy resources is of great concern. The sun is an extraordinary source of renewable

Potential annual daylighting performance of a high-efficiency daylight redirecting slat system

Results indicate significant potential lighting energy savings when compared with conventional automated reflective blinds or manually-operated matte white venetian blinds, while maintaining acceptable or better visual comfort conditions throughout the interior space.

Luminance pattern simulation: Design of an artificial BRE Average Sky

The outcome of a feasibility study to design an artificial sky to simulate the BRE Average Sky is described, which could be used in a wide variety of lighting design problems, whenever a highly controlled luminance pattern is required.

Concentrated and piped sunlight for indoor illumination.

It is argued that using sunlight directly for indoor illumination would be about twenty-five times more cost-effective than using sunlight to generate electricity with solar cells for powering electric lamps for indoor lighting.

Lighting with sunlight using sun tracking concentrators.

The use of controlled beams of sunlight for lighting interior parts of a building is proposed as an economically attractive and practical option in a solar energy context and a preliminary experiment is given.

Daylight in dynamic thermal modelling programs: Case study

Heating, cooling and lighting energy consumptions in buildings are inter-related, and a model which treats thermal performance and lighting simultaneously is required in order to evaluate the full
