Term Term Definition Lists Unit of Measure
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.

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).

fc
Input Resource Type

Resource or fuel consumed by the system. See Resource type for complete list of resources.

View N/A
Insulation Application

A description of the type of insulation and how it is applied.

View N/A
Insulation Continuity

Insulation installation type.

View N/A
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.

ft
Location

Spatial location or installation location. This can apply to systems, opaque surfaces, etc.

View N/A
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). 

cd/m2
Make

Equipment identification indicating manufacturer and or high-level category of equipment

N/A
Manufacturer

Manufacturer of the product.

N/A
Model Number

Model or catalogue number that can be used to identify more detailed component or asset characteristics.

N/A
Notes

Brief note on additional information.

N/A
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

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 N/A
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.

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.

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.

Percent
Perimeter

Length of a line forming the boundary around the premises

ft
Priority

Order of priority, for example: configuration of equipment, or priority of contact information.

View N/A
Quantity

The number of specified units

N/A
Quantity Intensity

The number of entities per unit area. This can be used to represent load densities (e.g., People/ft2, Watts/ft2)

Dependent on Qualifier/ft2
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.

n/a
R Value

The R-value, also known as thermal resistance, is a quantity determined by the temperature difference, at steady state, between two defined surfaces of a material or construction that induces a unit heat flow rate through unit area (R = _T/q). R-value is the reciprocal of thermal conductance. A unit of thermal resistance used for comparing insulating values of different materials, for the specific thickness of the material. The higher the R-value number, a material, the greater its insulating properties and the slower the heat flow through it. This R-value does not include the interior and exterior air film coefficients.

hr·ft2·°F/Btu
R Value Per Unit Dimension

The R-value of a material, per inch of thickness.

(R-value)/in
Rated Lifetime

Rated life time of operation in number of years.
