The location can be specified using the Location term.	Lists View	Unit of Measure None
Term Shell Area	Term Definition The total surface area of the exterior envelope of a building	Lists	Unit of Measure ft2
Term Sill Height	Term Definition Distance from the floor to the lower horizontal surface at the window opening.	Lists	Unit of Measure ft
Term Solar Heat Gain Coefficient	Term Definition 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.	Lists	Unit of Measure None
Term Solar Reflectance Index	Term Definition 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	Lists	Unit of Measure None
Term Vertical Surroundings	Term Definition Attachments to the outermost vertical surfaces of the premises.	Lists View	Unit of Measure None
Term Visible Transmittance	Term Definition The fraction of radiation in the visible solar spectrum (0.4 to 0.7 micrometers) that passes through a material. Legal values: 0-1.	Lists	Unit of Measure None
Term Weatherstrip Description	Term Definition Material used in weatherstipping application. This can apply to doors, windows, as well as system components such as refrigeration doors.	Lists View	Unit of Measure None
Term Weatherstrip Status	Term Definition Whether a premises or feature, such as a door or window, is weatherstripped.	Lists View	Unit of Measure None
Term Window To Wall Ratio	Term Definition 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.	Lists	Unit of Measure None

Term Azimuth	Term Definition 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	Lists	Unit of Measure deg

Term Building Energy Code Or Standard	Term Definition The name of an energy efficiency code or standard that is applied to building construction requirements.	Lists View	Unit of Measure None
Term Building Energy Code Or Standard Version	Term Definition The version number, such as "90.1" for ASHRAE Standard.	Lists	Unit of Measure None
Term Building Energy Code Year	Term Definition 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.	Lists	Unit of Measure YYYY

Term Capacity Qualifier	Term Definition The capacity refers to the energy or physical load amount that equipment can handle.	Lists View	Unit of Measure None
Term Cardinal Orientation	Term Definition 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.	Lists View	Unit of Measure None
