Gain type
|
Used to select the type of equipment the gain
component is being defined for. The available types are listed below.
-
Electric
- Gas
- Hot
water
- Steam
- Other
|
New
|
Used to create new gain sub-components, each
defined independently using the controls and setting listed below.
-
(New) gain — Whenever the New button is
pressed, and new gain sub-component panel is created. The controls provided for
it can be set independent of the other gain sub-components in the Properties
For: Gains dialog box.
-
Delete icon — Used to delete the gain
sub-component.
|
Name
|
Used to enter a name for the gain sub-component.
|
Design level calculation method
|
Contains controls used to select the Design level
calculation method to be used for calculating the nominal electric equipment
level for the room in which the equipment component is located.
-
Equipment level — When selected, the method used will be a straight insertion
of the electric equipment level (Watts or BTU’s) for the room.
- Power
per area — When selected, the method used will be a factor of equipment level
(Watts) per floor area of the room.
- Power
per person — When selected, the method used will be a factor of equipment level
(Watts) per person.
|
Design level
|
Used to set the total power level for the Equipment
level calculation method.
|
Watts per Zone Floor Area
|
Used to set the total power level in terms of unit
square footage for the Power per area calculation method.
|
Watts per Person
|
Used to set the total power level in terms of
persons for the Power per person calculation method.
|
Fraction latent
|
Used to set the amount of latent heat given off by
the equipment component in the room. Fraction latent is a decimal number
between 0.0 and 1.0. This number is multiplied by the total power consumed by
the equipment component to give the amount of latent energy produced. This
energy affects the moisture balance within the room the equipment component is
located.
|
Fraction radiant
|
Used to set the amount of long-wave radiant heat
being given off by the equipment component in the room. Fraction radiant is a
decimal number between 0.0 and 1.0. This number is multiplied by the total
power consumed by the equipment component to give the amount of long wave
length radiation gain from the equipment component.
|
Fraction lost
|
Used to set the amount of lost heat being given off
by the equipment component in the room. Fraction lost is a decimal number
between 0.0 and 1.0. This number multiplied by the total power consumed by the
equipment component to give the amount of heat which is lost and does not
impact the room energy balances. This might correspond to electrical energy
converted to mechanical work or heat that is vented to the atmosphere.
|
Schedule
|
Used to select a schedule describing the equipment
operational hours.
|
End usage category
|
Used to enter a user-defined end-use subcategory,
e.g., "Pumps", "Office Equipment", etc. 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 equipment component will be
assigned to the General end-use subcategory.
