Envelope
Term	Term Definition	Lists	Unit of Measure
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		ft2
Sill Height	Distance from the floor to the lower horizontal surface at the window opening.		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.		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		None
Vertical Surroundings	Attachments to the outermost vertical surfaces of the premises.	View	None
Visible Transmittance	The fraction of radiation in the visible solar spectrum (0.4 to 0.7 micrometers) that passes through a material. Legal values: 0-1.		None
Weatherstrip Description	Material used in weatherstipping application. This can apply to doors, windows, as well as system components such as refrigeration doors.	View	None
Weatherstrip Status	Whether a premises or feature, such as a door or window, is weatherstripped.	View	None
Window To Wall Ratio	Ratio of total window area to total wall area, where the total wall area is calculated using the floor to floor height, rather than the floor to ceiling height.		None

Global Terms
Term	Term Definition	Lists	Unit of Measure
Age	Age of premises or equipment in years.		years
Area	The space inside the boundary of a 2 dimensional shape. This can be used with many other terms, including Location, Conditioning Status, Opaque Surface, to characterize the area of particular components.		ft2
Aspect Ratio	The ratio of width to length, of a premises		None
Azimuth	Degrees clockwise from North. For a premises, it is the azimuth of the front facing element. It can also be applied to envelope components, such as walls, windows (fenestration), as well as on-site generation technologies, such as photovoltaic panels. Legal Values: 0 - 360		deg
Boolean	Generic term to add boolean constrained list options to any term	View	None
Building Energy Code Or Standard	The name of an energy efficiency code or standard that is applied to building construction requirements.	View	None
Building Energy Code Or Standard Version	The version number, such as "90.1" for ASHRAE Standard.		None
Building Energy Code Year	Year for the Energy Code or Standard used with the Energy Code term. As the energy codes and standards are updated, dates are assigned for version control. There can be significant changes between different year versions, so it is important to capture the year of the standard as it applies to the building in question.		YYYY
Capacity	The capacity value of the associated equipment or system		Unknown
Capacity Qualifier	The capacity refers to the energy or physical load amount that equipment can handle.	View	None
Cardinal Orientation	Orientation of a surface or premises in terms of the attributes of North, South, East and West. Can be applied to the orientation of the front of the building, of a specific surface (wall, roof), window or skylight, or on-site generation technology, such as photovoltaic panels. A diagram for the constrained list choices will be provided when the web site is developed.	View	None
