Appendices 7.
Glossary and Symbols 7.1.
Ambient lighting: Lighting throughout an area that produces general illumination. Ballast: A device used with a fluorescent or high intensity discharge (HID) lamp to obtain the necessary circuit conditions for starting and operating. Coefficient of utilization (CU): The ratio of luminous flux (lumens) from a luminaire calculated as received on the workplane to the luminous flux emitted by lamps. When used with skylights, the coefficient of utilization is the ratio of the luminous flux from skylights received on the workplane to the daylight entering the room from the bottom of the light wells. Daylight saturation: The condition where the interior daylight illuminance level equals or exceeds the specified design illuminance level and the lighting control system thus provides maximum lighting energy savings. At saturation, any further increase in daylight illuminance will not produce additional lighting energy savings. Diffuse (Lambertian) surface: A surface that emits or reflects light in all directions and has a constant luminance regardless of viewing direction. See also specular reflecting surface. Effective aperture (EA): A measure of the light-transmitting ability of a fenestration system. Effective aperture is the product of the skylight-to-floor ratio (SFR), the visible transmittance (Tvis) and the well factor (WF). EA values range from 0 to 1.0 and are typically less than 0.1 for most practical skylight systems. Fenestration: Any opening or arrangement of openings for the admission of daylight, including any devices in the immediate proximity of the opening that affect distribution. Fixture: The housing for a light source, usually providing attachment to the building, housing for the ballast and lamps, and connection to the power source.
appendices 7-1
Footcandle (fc): One footcandle equals one lumen per square foot (or the illuminance produced on a surface all points of which are one foot from a directionally uniform point source of one candela). lumens 1fc = 10.76 lux = ––––––––– 2 m Glazing Efficacy (GE): The measurement of the ability of the glazing material to transmit visible light, in relation to the amount of solar heat it admits into the building. Glazing efficacy is the visible light transmittance divided by the solar heat gain coefficient. Glazing efficacy is the same as the light-to-solar gain ratio (LSG). High intensity discharge (HID) lamp: Electric discharge lamps that include metal halide, high pressure sodium, and mercury vapor lamps. High-performance glazing: Typically defined as glazing with Tvis > SC (glazing efficacy >1.0). Illuminance: The density of the luminous flux incident on a surface, expressed in units of footcandles (or lux). Integral curb: The attachment between the roof and the skylight frame (curb) is premanufactured as part of the skylight frame, typically of the same materials as the frame. Lighting power density (LPD): A measure of the amount of electric lighting installed in a building. Expressed as the number of Watts of lighting power required for the luminaires and lamps installed in a building, divided by the gross number of square feet in the building (Watts/square foot). Also known as unit power density. Light-to-Solar Gain Ratio (LSG): The ratio of visible light transmittance to solar heat gain coefficient for a glazing assembly. The ratio of the fraction of light transmitted to the fraction of solar heat gain transmitted through a glazing assembly. Low-emissivity (Low-e) coating: A coating applied to glazing that selectively transmits short wave radiation (such as light) but reflects long wave (infrared) radiation. Lower heat losses and lower U-values result from applying low-e coatings to glazing. Lumen: The luminous flux emitted within a unit solid angle by a point source having a uniform luminous intensity of one candela. Luminaire: A complete lighting unit consisting of a lamp, or lamps, together with parts designed to distribute the light, to position and protect the lamps, and to connect the lamps to the power supply. Luminous efficacy (LE): A measure of the luminous efficiency of a radiant flux, expressed in lumens per Watt. For daylighting, this is the ratio of visible flux incident on a surface divided by radiant flux on that surface. For electric sources, it is the ratio of the total luminous flux emitted divided by the total lamp or luminaire power input.

Photocontrols: Lighting control system that adjusts the electric lighting power in response to the amount of interior light or ambient daylight available. Shading coefficient (SC): The dimensionless ratio of the total solar heat gain from a particular glazing system to that for one sheet of clear 3mm (1/8”) double-strength glass. The solar heat gain is the sum of the transmitted solar energy plus that portion of the absorbed solar energy which flows inward. This term is being gradually replaced by the more accurate Solar Heat Gain Coefficient. Skylight efficacy (SE): The measurement of a skylight system’s ability to transmit visible light, in relation to the amount of solar heat it admits into the building. The product of the Light-to-Solar Gain Ratio (LSG) and the Well Factor (WF). Skylight-to-Floor Ratio (SFR): The ratio of gross skylight opening area to daylit floor area. Solar altitude: The vertical angular distance of the sun in the sky above the horizon. Solar azimuth: The horizontal angular distance between the vertical plane containing the sun and true south. Solar Heat Gain Coefficient (SHGC): The fraction of solar radiation admitted through a glazing assembly; the sum of the transmitted solar energy plus that portion of the absorbed solar energy which flows inward. Solar transmittance: The transmittance of a glazing material or skylight assembly over the complete solar spectrum. Specular reflective surface: A surface characterized by the reflectance of light rays striking and leaving the surface at equal angles. Task lighting: Lighting provided to a local area to provide sufficient illumination for a specific work task, such as a desk lamp, overhead lighting at shelves, or portable lamps for industrial tasks. Usually paired with ambient lighting, providing a lower level of general illumination. Unit power density: See lighting power density. U-value: A measure of a material’s heat transfer capabilities when placed between two 2
spaces of different temperatures, typically given in Btu/hr·ft ·°F. The U-value is the inverse of the R-value, which measures the material’s resistance to heat transfer. Visible transmittance (Tvis or VT): The transmittance of a particular glazing material or skylight assembly over the visible portion of the solar spectrum. Well Factor (WF): The ratio of the amount of visible light leaving a skylight well to the amount of visible light entering the skylight. Well Cavity Ratio (WCR): A parameter used to determine the light well factor. Well cavity ratio is a measure of the geometric shape of the well, and is calculated as follows:
