HVAC
Term	Term Definition	Lists	Unit of Measure
Refrigerant Charge Factor	Used to adjust cooling efficiency for assumed slightly degraded performance if refrigerant charge is not verified through acceptance test procedures		percent
Reheat Source	Energy source used to provide reheat energy at a terminal unit.	View	None
Required Ventilation Rate	Minimum ventilation rate required by local code.		cfm
Return Duct Percent Conditioned Space	Percentage of return duct surface area, including the air handler, that is located within conditioned space (0-1).		percent
Sequencing	Sequencing availability of HVAC system	View	None
Static Pressure	The expected or installed internal static pressure of the system at full supply fan speed including all filters, coils, and accessories.		Pa
Supply Duct Percent Conditioned Space	Percentage of supply duct surface area that is located within conditioned space (0-1).		percent
Supply Fraction Of Duct Leakage	Fraction of total duct leakage that is on the supply side. Remainder is assumed to be on the return side (0-1).		None
System Performance Ratio	Ratio of annual system load to the annual system energy consumption (similar to a whole system COP). A higher value indicates less heating and/or cooling energy use to meet the loads, and therefore represents a more efficient HVAC system. SPR can be used to describe the heating, cooling, and overall HVAC systems.		None
Ventilation Rate	Installed flow rate for mechanical ventilation system.		cfm
Ventilation Type	Type of ventilation, and use of heat recovery	View	None
Water Side Economizer	Presence of water-side economizer to provide free cooling.	View	None
Water Side Economizer Type	Type of waterside economizer providing free cooling.	View	None

Audio Visual Characteristics	Audio and visual equipment characteristics or features installed standard or post-manufacturing.	View	None
Average Effluent Biological Oxygen Demand	Average Effluent Biological Oxygen Demand (BOD5) is the BOD5 concentration of wastewater after it is treated and is leaving a Wastewater Treatment Plant. The concentration should be an average concentration, estimated over a 12-month period. BOD is the measure of the amount of oxygen required by bacteria for stabilizing material that can be decomposed under aerobic conditions. BOD5 is a commonly used determinant of the organic strength of a waste, recording the oxygen demand over a five-day period.		mg/L
Average Influent Biological Oxygen Demand	Average Influent Biological Oxygen Demand (BOD5) is the BOD5 concentration of wastewater when it is entering a Wastewater Treatment Plant to be treated. The concentration should be an average concentration, estimated over a 12-month period. BOD is the measure of the amount of oxygen required by bacteria for stabilizing material that can be decomposed under aerobic conditions. BOD5 is a commonly used determinant of the organic strength of a waste, recording the oxygen demand over a five day period.		mg/L
Ballast Type	A ballast is a piece of equipment required to control the starting and operating voltages of electrical gas discharge lights.	View	None
Battery Charger Type	A device intended to replenish the charge in a rechargeable battery. A battery charger connects to the mains at the power input and connects to the battery at the output. The charger may be comprised of multiple components, in more than one enclosure, and may be fully or partially contained in the Battery Operated End-use Product.	View	None
Battery Device Type	A type of battery device.	View	None
Cabinet Configuration	Configuration can include refrigeration cases and walk-ins, not central refrigeration systems.	View	None
Case Door Orientation	Orientation of refrigerated case doors used for display cases at stores, food-service establishments.	View	None
Clothes Dryer Drum Capacity	This is the drum capacity of the clothes dryers in cubic feet as measured by the U.S. Department of Energy test procedure, Code of Federal Regulations, Title 10, Section 430, Subpart B, Appendix D2. Products with a drum capacity less than 4.4 cubic feet are considered compact.		ft3
Clothes Dryer Type	The type of clothes dryer appliance.	View	None
Clothes Washer Integrated Modified Energy Factor	The quotient of the cubic foot (or liter) capacity of the clothes container divided by the total clothes washer energy consumption per cycle, with such energy consumption expressed as the sum of the machine electrical energy consumption, the hot water energy consumption, the energy required for removal of the remaining moisture in the wash load, and the combined low-power mode energy consumption.		ft3/(kBtu/cycle)
Clothes Washer Modified Energy Factor	Modified Energy Factor, MEF, is the energy performance metric for ENERGY STAR qualified clothes washers and all clothes washers as of February 1, 2013. MEF is the quotient of the capacity of the clothes container, C, divided by the total clothes washer energy consumption per cycle, with such energy consumption expressed as the sum of the machine electrical energy consumption, M, the hot water energy consumption, E, and the energy required for removal of the remaining moisture in the wash load, D. The higher MEF, the more efficient the clothes washer. The equation is: MEF = C/(M + E + D).		ft3/(kBtu/cycle)
