Complete Solutions
AFUE - ANSWER-Annual Fuel Utilization Efficiency
ASHRAE - ANSWER-American Society of Heating, Refrigeration and Air Conditioning
Engineers
ASTM - ANSWER-American Society for Testing of Materials
Ballast - ANSWER-A device used with a discharge lamp to provide the necessary circuit
conditions (voltage, current, and waveform) to start and operate the lamp.
Boiler Air Leakage("Tramp Air") - ANSWER-Air passing through damaged or poorly
maintained door seals. Will affect SSE reading if not recognized and properly
interpreted.
Burn Efficiency - ANSWER-The ratio of Btu content of fuel vs. Btu's realized through
combustion.
CCT - ANSWER-Correlated Color Temperature
CO - ANSWER-Carbon Monoxide
CRI - ANSWER-Color Rendering Index
DHW - ANSWER-Domestic Hot Water
Distribution Efficiency - ANSWER-Efficiency of the distribution system. It is the ratio of
heat in the air, water or steam that enters the distribution piping/ducting, to the heat
delivered to the space via terminal units (radiators, fin tube, etc).
EEMs - ANSWER-Energy Efficiency Measures
Efficacy - ANSWER-The efficiency of the lamp, expressed in Lumens per watt (LPW). It
is the ratio of the total light (lumen) output over the total energy (watt) input.
EPA - ANSWER-Environmental Protection Agency
ERV - ANSWER-Energy Recovery Ventilator
Foot Candles - ANSWER-Units of light density striking a surface. One footcandle is
defined as one lumen distributed uniformly over one square foot.
