Term	Term Definition	Options	Unit of Measure
Supply Duct Percent Conditioned Space	Percentage of supply duct surface area that is located within conditioned space (0-1).	View	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).	View	None
Supply only		View	None
Supply UPS output meter		View	None
Supply voltage dips	A count of Supply Voltage Dip events during the summary interval period	View	None
Supply voltage imbalance	A count of Supply Voltage Imbalance events during the summary interval period	View	None
Supply voltage variations	A count of Supply Voltage Variations during the summary interval period	View	None
Supply water temperature	The water temperature that the equipment supplies, such as the chilled water temperature setpoint for a chiller, or hot water temperature setpoint for water leaving a boiler.	View	None
Surface	A recessed luminaire is installed on a surface, such as on a wall or ceiling, rather than being hanging down-- suspended -- from the ceiling or in a recessed ceiling cavity. Luminaires can also be installed in cabinets, floors, and other surfaces.	View	None
Surface Roughness	A description of the roughness of the exposed surface of a material. This property is used to approximate the effect of the surface condition on the convection of air across the surface. In energy simulation models, it is used to help determine the convection coefficients for a surface.	View	None
Suspended	A suspended luminaire is installed from a surface, such as on a wall or ceiling, rather than on the ceiling or in a recessed ceiling cavity. Luminaires can also be installed in cabinets, floors, and other surfaces.	View	None
Suspended	Located above/below/in some other suspended element	View	None
Suspended	Located above/below/in some other suspended element	View	None
Suspended film	A film that is suspended between two glass layers that has the following properties: Thick < 0.5 mm	View	None
Suspended linear	Suspended linear	View	None
Sweep	A manufactured products made of a combination of materials such as plastic and metal to fill the space between the bottom of the door and the threshold.	View	None
Swimming pool		View	None
Swinging		View	None
Switch	A network device that filters, forwards, and floods frames based on the destination address of each frame as its primary function. The switch operates at the data link layer of the OSI model.	View	None
Synchronous belts		View	None
System	Cost associated with a system	View	None
System		View	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.	View	None
T Shape		View	None
T10	Fluorescent tube with a 1 1/4 inch (31.75 mm) diameter.	View	None
