Term	Term Definition	Options	Unit of Measure
Dimension	A linear measurement in one direction. Can be used to generically describe this measurement, if needed.	View	ft
Duty Cycle	Percent of time the system operates.	View	percent
Effective R Value	The R-value of a complete construction including all material layers as well as the interior and exterior air film coefficients.	View	hr-ft2-F/Btu
Efficiency Metric Qualifier	The measure used to quantify efficiency	View	None
Efficiency Qualifier	Variations in the quantification of the effectiveness with which equipment, a product, process, or system performs.	View	None
Efficiency Value	The numeric value associated with an Efficiency Qualifier, given in the associated Efficiency Metric	View	Unknown
Eh	Illuminance (horizontal)	View	fc
Emittance	The capacity of a material to emit radiant energy. The ratio of the radiant flux emitted by a physical surface to that emitted by a blackbody at the same temperature and under the same conditions. It can be expressed as 1-(long-wave infrared absorptance) for materials that are not transparent in the long-wave infrared spectrum. Emittance is a surface property; values range from 0.05 for brightly polished metals to 0.96 for flat black paint. The emittance for most materials is 0.9.	View	None

Ev	Illuminance (vertical)	View	fc
Exposure	Exposure of a material or surface. See the Location term for a complete list of options for this term.	View	None
Height	The dimension of an object from the bottom to the top. This can be used to define the height of any building component, such as the height of a wall or window.	View	ft
Illuminance	The area density of the luminous flux incident at a point on a surface. Measured in units of either lumens per square meter (lux) or lumens per square foot (footcandle).	View	fc
Input Resource Type	Resource or fuel consumed by the system. See Resource type for complete list of resources.	View	None
Insulation Application	A description of the type of insulation and how it is applied.	View	None
Insulation Continuity	Insulation installation type.	View	None
Length	The longest dimension of an object. This can be used to define the length of any building component, such as ductwork or piping, or an opaque surface such as a wall or floor.	View	ft
Location	Spatial location or installation location. This can apply to systems, opaque surfaces, etc.	View	None
Luminance	The photometric measure of the luminous intensity per unit area of light travelling in a given direction, expressed in candelas per square meter (cd/m2).	View	cd/m2
Make	Equipment identification indicating manufacturer and or high-level category of equipment	View	None
Manufacturer	Manufacturer of the product.	View	None
Model Number	Model or catalogue number that can be used to identify more detailed component or asset characteristics.	View	None
