A Foot-candle is a unit of illuminance or illumination, equivalent to the illumination produced by a source of one candle at a distance of one foot and equal to one lumen incident per square foot. Abbreviation: FC
Our energy consultants and lighting design specialists will perform an on-site energy audit of your facility. During the audit one of the measurements we take are foot-candle readings. Using a light meter and measurement tools we’ll take accurate foot-candle readings at points all throughout your facility. We then use 3D lighting design and modeling software to build out a replica of your space from the information gathered (including foot-candle readings) during this audit. This becomes your digital blueprint and we’ll use this blueprint with our expert knowledge in lighting to test and propose more efficient fixtures and systems that meet recommended light levels and advance your businesses objectives.
Foot-candle (FC) readings are one of the ways our lighting design specialists and project managers measure and quantify light levels in commerical or industrial spaces.
By using Footcandles we’re able to measurably demonstrate the existing light levels in a space and compare those to the expected and actual light levels in a newly designed or proposed lighting solution.
How do we increase or decrease light levels in a facility
Our energy consultants and lighting design specialists perform an on-site audit of your facility, we use 3D lighting design and modeling software to build out a replica of your space from the information gathered during this audit. We use this as a digital blueprint to test and propose more efficient fixtures that meet or exceed (when appropriate) your light level requirements. This complex tool is one of the ways we ensure our designs generate targeted light levels that meet your building’s specific needs.
Using photometric imagery we can compare current light levels to our new design measuring and directing light, adjusting the optics as necessary to deliver the right amount of light to the right areas.
In the photometric images below red indicates higher light levels and FC readings where blue is the low end of the FootCandle reading spectrum.
We use the Illuminating Engineering Society (IES) guidelines as a standard for appropriate light levels. IES is an industry-backed, “Lighting Authority” that establishes new construction light level standards and OHSA light level standards for a range of commercial and industrial workspaces and environments.
