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.

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.

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

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

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.
