Area type
|
Used to select the type of external building area
to be illuminated. The types drop-down list is populated with all the different
types of building areas. Select one and press New.
|
New
|
Press to create new exterior lighting
sub-components for the building. Each of these lighting sub-components’
characteristics can then be defined independently.
- (New) lighting area
— When the New icon is pressed, a default properties panel opens with options
for defining the new luminaire.
- Delete icon — Used
to delete the building lighting sub-component.
|
Name
|
Used to enter a name for the luminaire. Once
entered, the name appears in the property separator bar. Minimize the bar when
you are not manipulating the luminaire characteristics.
|
Area
|
Used to enter an area value the new building
lighting type is to illuminate. The Area field is used for lighting designed to
illuminate areas, and is disabled for area types which require lighting that
illuminates based on a linear distance that is illuminated. They use the Length
property to define their illumination pattern.
|
Length
|
The Length field is used for lighting whose design
is based on a linear distance that is to be illuminated, and is disabled for
area types which require lighting that is designed to illuminate areas. They
use the Area property to define their illumination pattern.

Category
|
Used to select the luminaire type from these
available luminaire categories:
- Linear fluorescent
— A gas discharge lamp that uses electricity to excite mercury vapor. The
excited mercury atoms produce short wave ultraviolet light that causes a
phosphor to fluoresce, producing visible light. A linear fluorescent lamp
converts electrical power into useful light more efficiently than an
incandescent lamp. The linear fluorescent lamp fixture requires a ballast to
regulate the current through the lamp.
- Compact fluorescent
— A fluorescent lamp of a small compact shape, with a single base that provides
the entire mechanical support function. Compact fluorescent sources are three
to four times more efficient than the traditional incandescent lamps they are
designed to replace. To achieve credit towards compliance, the compact
fluorescent lamp fixture must have a permanently installed ballast.
- HID - High Pressure
Sodium — An electric discharge lamp in which light is produced when an electric
arc is discharged through high pressure vaporized sodium. It may also have a
phosphor coating that contributes to the light produced or enhances the light
color.
- HID - Low Pressure
Sodium — An electric discharge lamp in which light is produced when an electric
arc is discharged through low pressure vaporized sodium. It may also have a
phosphor coating that contributes to the light produced or enhances the light
color.
- HID - Metal Halide
— An electric discharge lamp which produces high light output in a small size,
making it a compact, powerful, and efficient light source. HID metal halide
lamps operate under high pressure and temperature, and require special fixtures
to operate safely.
- HID - Ceramic Metal
Halide — An electric discharge lamp in which the discharge is contained in a
ceramic tube. Ceramic metal halide lamps use one fifth of the power of
comparable incandescent bulbs for the same light output, and retain color
stability better than most other gas discharge lamps.
- Incandescent — A
lamp in which light is produced by a filament heated to incandescence by an
electric current. Incandescent lamps are three to four times less efficient
than compact fluorescent lamps.
- Halogen — Also
known as a tungsten halogen lamp, is an incandescent lamp with a tungsten
filament contained within an inert gas and a small amount of a halogen such as
iodine or bromine. The combination of the halogen gas and the tungsten filament
produces a chemical reaction known as a halogen cycle which increases the
lifetime of the filament and prevents darkening of the bulb by redepositing
tungsten from the inside of the bulb back onto the filament. A halogen lamp can
be operated at a higher temperature than a standard gas-filled lamp of similar
power and operating life.

Lamp
|
Used to select lamps to be used for the selected
luminaire fixture (Category). Lamps are determined by the chosen luminaire
category, ensuring the right type of lamp is selected:
- For linear
fluorescent — Length , type and wattage are listed.
- For compact
fluorescent — Twin tube, triple 4–pin, quad 2–pin, BIAX, spiral, reflector
types and wattage are listed.
- For HID categories
— Wattage from 18W to 1000W are listed.
- For incandescent —
Wattage from 20W to 1000W are listed.
- For halogen —
Halogen and Halogen MR types and wattag are listed.
|
Ballast
|
Used to select the ballast type to be used for the
selected luminaire fixture (Category). A ballast is a device used in
conjunction with an electric discharge lamp to cause the lamp to start and
operate under the proper circuit conditions of voltage, current, wave form,
electrode heat, etc. Ballast choices are determined by the chosen luminaire
category. They are:
- Standard — Also
known as an electronic ballast, constructed using electronic circuitry.
- Metallic —
Constructed with magnetic core and a winding of insulated wire.
|
End usage category
|
Allows you to specify a user-defined end-use
subcategory, for instance, "Lighting Conditioned", "Lighting Unconditioned",
etc. for the lighting component used in the building. A new meter for reporting
is created for each unique subcategory. Subcategories are also reported in the
ABUPS table. If this field is omitted or blank, the lights will be assigned to
the General end-use subcategory.
|
Lamps per fixture
|
Used to enter the number of lamps to be used per
fixture of the chosen luminaire category.
|
Number of fixtures
|
Used to enter the number of fixtures of the chosen
luminaire category to be considered as belonging to the active luminaire
lighting sub-component.
|
Fixture wattage
|
Used to enter the total fixture wattage.
|
Exemption
|
Used to select an exemption from lighting power
allowance requirements for the luminaire. Although, most lighting power is
subject to the requirements of the ASHRAE 90.1 standard, some lighting for
specialized commercial and display purposes, such as outdoor manufacturing,
retail display windows, televised sports lighting, theatrical productions, and
lighting integral to medical equipment, is exempt. Also exempt are certain
lighting systems or portions of systems required for emergency use.
|
Schedule
|
Used to select a default lighting schedule for the
lighting component used in the building.
