15 Jun 2011 It is recommended that lower lighting zone(s) be given preference when for Uplight, and Table C-3 for Glare, without the need for external.

Based on your facility, there are recommended light levels. The levels are based on a unit of measure called foot candles (fc) or lumens (lm). This rating quantifies how much light is in an area. The following selected foot- candle ranges represent the Illuminating Engineer Society’s (IES) current illumination recommendations. SAVING ENERGY IN COMMERCIAL BUILDINGS | Lighting System Assessment Guidelines Table 1. Recommended Illuminance (IES) and Lighting Power Density 1.(ASHRAE 90.1 version) by Space Type2. IESNA Recommended Horizontal Illuminances and ASHRAE/IESNA 90.1 LPD Recommendations Space Type Illuminance (fc) LPD (W/ft²) Open Offices 30 to 50 (5 to 10 with task A foot candle is actually one lumen of light density per square foot; one lux is one lumen per square meter. • 1 lux = 1 lumen / sq meter = 0.0001 phot = 0.0929 foot candle (ftcd, fcd) • 1 phot = 1 lumen / sq centimeter = 10000 lumens / sq meter = 10000 lux • 1 foot candle (ftcd, fcd) = 1 lumen / sq ft = 10.752 lux A typical standard for painting facilities is 100-150 foot candles at a height of three feet. The type of tasks may also dictate the level of lighting required: dripping, simple spraying and ordinary hand painting may incorporate 20-50 foot candles lighting measurements. Once you’ve measured the room and calculated the required foot candles, it’s time to determine how many lumens a space needs. Multiply your room square footage by your foot candle requirement. Here’s an example using a 100 square foot living room: 100 sq. ft. X 10-20 foot candles = 1,000 to 2,000 lumens. A foot-candle (fc) is the unit used to measure the amount of light hitting a surface from 30 degrees above the horizontal plane of the surface. It is equal to the amount of light 1 foot away from the surface being lit by a candle. Lumens are the units for measuring the amount of light emitted by a source.

A foot candle is actually one lumen of light density per square foot; one lux is one lumen per square meter. • 1 lux = 1 lumen / sq meter = 0.0001 phot = 0.0929 foot candle (ftcd, fcd) • 1 phot = 1 lumen / sq centimeter = 10000 lumens / sq meter = 10000 lux • 1 foot candle (ftcd, fcd) = 1 lumen / sq ft = 10.752 lux

You can also calculate the number of watts directly from foot-candles by combining both equations & using the following: Watts = Foot Candles x 0.01609696 (since 10.76 x 0.001496 = 0.01609696) The Illuminating Engineering Society, IES, has recommended the following foot candle levels to ensure adequate illumination and safety for occupants. Using the foot candle calculator: an example. Choose the area of the house that you want to illuminate. Let's say you're planning the lighting for your kitchen, including the kitchen counter. Check the optimal lighting level. For the whole kitchen, it is 108 lux, and for the counter (detailed tasks) - 538 lux. Many existing facilities have much higher than recommended footcandle levels, and this devices) per unit area of a building in watts per square foot.

A general light level guide for businesses, facility managers, etc. Individual applications will determine exact foot-candle levels.
