Term	Term Definition	Options	Unit of Measure
Notes	Brief note on additional information.	View	None
Occupant Usage Units	Measurement units for typical occupant usage	View	None
Offset	Distance from the edge of a surface to another surface or object. Offset can be used to help describe a building shape, as used in Commercial Asset Score Tool. It can also be used to describe the location of a window in a wall, where offset is used to describe the distance from the edge of al wall to the edge of a window frame	View	ft
Output Resource Type	Resource or fuel produced by the system and used as energy on the premises. See Resource type for complete list of resources.	View	None
Percentage Of Total Area	Percent of a component to the total area of another component. This can be used to characterize the percentage of Conditioned Floor Area to Gross Floor Area, for example.	View	percent
Percentage Of Total Floor Area Served	Portion of the total floor area within a defined zone that is being served by a system, piece, or set of equipment.	View	percent
Percentage Of Total Installed Capacity	Percentage of maximum, peak or rated installed capacity of a system, piece, or set of equipment that is either available or being used.	View	percent
Perimeter	Length of a line forming the boundary around the premises	View	ft
Preferred Contact		View	None
Priority	Order of priority, for example: configuration of equipment, or priority of contact information.	View	None
Quantity	The number of specified units	View	count
Quantity Intensity	The number of entities per unit area. This can be used to represent load densities (e.g., People/ft2, Watts/ft2)	View	Unknown
Quantity Of Units Per System	Number of units in each system. For instance, a photovoltaic system will have a number of modules per array. In an office, there might be a number of displays per workstation.	View	count
R Value	The R-value, also known as thermal insulance, is the temperature difference per unit heat flux, at steady state, between two defined surfaces of a material or construction that induces one unit of heat flux between the surfaces. The R-value is used for comparing insulating values of different materials, for the specific thickness of the material. The higher the R-value, the greater a material's insulating properties and the slower heat flows through it. The R-value does not include the interior and exterior air film coefficients. The R-value is the reciprocal of the U-factor.	View	hr-ft2-F/Btu
R Value Per Unit Dimension	The R-value of a material, per inch of thickness.	View	hr-ft2-F/(Btu-in)
Rated Lifetime	Rated life time of operation in number of years.	View	years
Ratio of Melanopic to Standard Illuminance (M/P ratio)	M/P ratio - The melanopic ratio is the ratio of the melanopic response (of the cells in the eye that help control the circadian rhythms) to the visual response	View	None
Sector Classification	The sector classification appropriate for the premises. Also, the sector-appropriate sizing for equipment.	View	None
Serial Number	A unique code assigned for identification of a single unit.	View	None
Solar Absorptance	The fraction of incident radiation in the solar spectrum that is absorbed by the material or surface. Value range: 0-1	View	None
Spacing	Dimension of the distance between two components. Examples include: Framing spacin--the dimension from centerline to centerline of a surface framing material; Window spacing--the dimension between windows in a discrete window layout.	View	ft
Specific Heat	Ratio of the quantity of heat required to raise the temperature of a given mass of any substance one degree to the quantity required to raise the temperature of an equal mass of a standard substance one degree (usually water at 59¡F (15¡C)	View	Btu/(lb-F)
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
Thermal Absorptance	The fraction of incident long wavelength infrared radiation that is absorbed by the material or surface. For opaque materials the thermal absorptance value will equal the value of thermal emittance. Value range: 0-1	View	None
Thermal Conductance	A measure of a material's ability to conduct heat, defined as the heat flux through the material induced by a unit temperature difference between the surfaces of the material.	View	Btu/(hr-F)
