The color and diffusion of these materials will determine the success of the design as well as contributing to glare control. Luminaires in houses of worship are likely to incorporate translucent elements. Any glare in the field of vision for participants must be avoided. Glare control, always an issue in lighting design, is a critical element in houses of worship. Luminaire material finishes must be coordinated. Every element of the architecture, including, or even especially, the luminaires, must work in a cohesive fashion to strengthen the overall impression of space and light.
Luminaire aesthetics are critical, whether the church is a traditional or modern design. With a real-life heritage project to illustrate. This article is an overview of the design issues and challenges of lighting in houses of worship. Lighting should acknowledge and enhance this deeply personal act…” “Worship is an intensely personal endeavor that may or may not involve a community of participants. The name “footcandle” conveys “the illuminance cast on a surface by a one-candela source one foot away.All photos courtesy of Deborah Gottesman, Photography by Cody Stone Cooper freedom from glare, shadows and correct distribution.įrom Wikipedia “A foot-candle is a unit of illuminance or light intensity widely used in the lighting industry. Besides the quantity, lighting should also be evaluated in terms of it’s quality, i.e. This is the measurement you’ll work with the most for optimizing visual comfort because building regulations and standards use illuminance to specify the minimum light levels for specific tasks and environments.
The amount of light falling on a surface is “illuminance”, and is measured in lux (metric unit = lumen/m2) or foot-candles (English unit = lumen/ft2). see What to Know Before Purchasing Commercial Industrial Lighting Please refer to the IES Lighting Handbook for more detailed evaluation. Individual applications will determine exact foot-candle levels. A general light level guide for businesses, facility managers, etc. Following are the current recommended Illuminance categories and Illuminance values for lighting design. Lighting Level Recommendations uses uses published recommended illuminance levels for a multitude of tasks and facility types from the Illuminating Engineering Society to demonstrate how to light a room.
