TL;DR: The single most used lighting design parameter today is the average illuminance on the horizontal working plane as discussed by the authors, which has been shown to be useful for specifying known requirements but insufficient thought has, in the Authors' opinion, been given to the problems of understanding what a parameter means, its prediction and its measurement.
Abstract: The single most used lighting design parameter today is the average illuminance on the horizontal working plane. A number of attempts to introduce other lighting parameters into the design procedure have been made from time to time, but with little success. In most designs only the average illuminance on the horizontal working plane is considered. In a small percentage of designs glare index is also taken into account. Designs to a higher technical specification are rare. This paper investigates why this situation exists and what can be done about it. Considerable thought has been given to what parameters are useful for specifying known requirements, but insufficient thought has, in the Authors' opinion, been given to the problems of understanding what a parameter means, its prediction and its measurement. Any designer who tries to satisfy all of the requirements of the 1977 IES (CIBS) Interior Lighting Code will find that the methods available for doing so are fragmented, confusing and often unpractical....

TL;DR: The author reviews the development of performance indicators for the evaluation of daylighting systems and the comparative strengths and weaknesses of measures including the daylight factor, the glare index, the scalar illuminance, the illumination vector, and the ratio of the vertical illuminances to the horizontal illumination are discussed.

TL;DR: In this paper, a review traces architectural themes and the corresponding concerns of lighting researchers and explores how they have applied the results of scientific research into lighting design and application and how they applied these results to architectural applications.
Abstract: Architectural developments over the past 50 years have been dramatic and have been paralleled by active research in lighting. This review traces architectural themes and the corresponding concerns of lighting researchers and explores how they have applied the results of scientific research into lighting design and application.

TL;DR: The Method of Designed Appearance, which commences with the consideration of the appearance of the lighted interior and the specification of the luminances of the principal surfaces, has been applied to a simple rectangular interior and is shown to lead to a very simple design procedure which can be reduced to a work sheet, one Table and one set of curves.

TL;DR: A review and discussion of approaches for the treatment of obstructions in lighting design can be found in this article, where a number of approaches have been proposed for building interiors with objects which project above the working plane.
Abstract: The majority of general lighting installations are planned assuming that the space between luminaire plane and working plane is empty. Most building interiors, however, contain objects which project above the working plane. This paper reviews and discusses some of the approaches that have been put forward for the treatment of obstructions in lighting design. Suggestions for future development are made.

TL;DR: In this paper, a modified maximum spacing-to-height ratio was proposed to allow for obstruction loss and which could be used in addition to the normal spacing to height ratio in installation design.
Abstract: Most of the published work on the lighting of obstructed interiors is concerned with the development of calculation procedures to enable designers to investigate the lighting conditions in a quantitative or qualitative way for particular configurations of room geometry, contents and lighting equipment. This general approach is appropriate only if the designer has detailed knowledge of the space to be lit. In the design of a building where the eventual nature of the interior space is not known, more general design guidance for obstructed spaces is required in the initial synthesis stage of the design process. This paper develops the idea of extending existing guidance for lighting design for empty rooms by adopting a modified maximum spacing-to-height ratio which allows for obstruction loss and which could be used in addition to normal spacing-to-height ratio in installation design.
