Term	Term Definition	Options	Unit of Measure
Foundation Ground Coupling	The type of coupling between foundation and ground. Use Location and Conditioning Status terms to further qualify coupling.	View	None
Foundation Height	Height of the premises foundation. [NOTE: The Location term can be used to further refine this definition, such as Foundation Height Above Grade or Foundation Height Below Grade.]	View	ft
Foundation Perimeter Insulation	Is the foundation perimeter insulated.	View	None
Framing Factor	Fraction (0-1) of the surface that is composed of structural framing material.	View	None
Glazing Diffusing Description	If the Fenestration Glass Type is diffusing (the material is not clear and causes light coming through it to be scattered), type of diffusing surface	View	None
Horizontal Surroundings	Attachments to the outermost horizontal surfaces of the premises.	View	None
Material	Material used in the construction of an opaque surface.	View	None
Material Qualifier	A description of how the material is applied.	View	None
Moveable Insulation	Indication of whether or not a fenestration product has moveable insulation. This type of insulation can be applied when needed, such as on a hot summer day or a cold winter night, and removed when it is not needed.	View	None
Number Of Fenestration Units	Number of windows, skylights, glass doors, etc associated with a surface, a zone, a premises, etc.	View	count
Opaque Surface	Opaque Surface type	View	None
Opaque Surface Component	Element or characteristic of an opaque surface	View	None
Percent Glazing	The percentage of an opaque surface or door that is glazed	View	percent
Percent Of Fenestration Area Shaded	The percent of the fenestration area that is shaded by exterior objects such as trees or other premises'.	View	percent
Percent Skylight Area	The percent of the skylight area relative to the roof area.	View	percent
Percent Vision Glazing	The percent of the glass portion of an exterior window, relative to the wall area, that permits views to the exterior or interior. Vision glazing must allow a clear image of the exterior and must not be obstructed by frits, fibers, patterned glazing, or added tints that distort color balance. (USGBC)	View	percent
Plumbing Penetration Sealing	Type of plumbing penetration sealing	View	None
Radiant Barrier	Type of radiant barrier in the construction	View	None
Radiant Barrier Location	Installed location of radiant barrier	View	None
Roof Shape	Architectural description of the exterior shape of the roof. If the roof has more than one shape, this is the primary roof shape. Illustrations to be added when the website is developed.	View	None
Shading System	A system that can be added to a fenestration system which blocks or redirects some amount of the solar radiation coming through the fenestration system. A shading system can be located on the inside or outside of a fenestration system, and it can also be added between the glass (or plastic) layers of a glazing system. The location can be specified using the Location term.	View	None
Shell Area	The total surface area of the exterior envelope of a building	View	ft2
Sill Height	Distance from the floor to the lower horizontal surface at the window opening.	View	ft
Solar Heat Gain Coefficient	The ratio of the solar heat gain entering the space through the fenestration product to the incident solar radiation. Solar heat gain includes directly transmitted solar heat and that portion of the absorbed solar radiation which is then reradiated, conducted, or convected into the space. Legal values: 0-1.	View	None
Solar Reflectance Index	A measure of a roof's ability to reject solar heat, as shown by a small temperature rise. It is defined so that a standard black (reflectance 0.05, emittance 0.90) is 0 and a standard white (reflectance 0.80, emittance 0.90) is 100. SRI	View	None
