conference room next door, and an office break room is modeled differently
from a typical restaurant dining room. Lighting, population density, activity
levels, equipment, and ventilation loads all vary with the space type.
If you open the Manage tab and then choose MEP Settings Building/Space
Type Settings, you will be able to view and modify the space type options
within Revit MEP as well as the global building types (see
Figure 8.5
)
.
In the Building/Space Type Settings dialog box, you can choose to define
overall building types or individual space usage types. Defining an overall
building type can be a good option if you want to do a quick takeoff of a
typicalbuildingtypefortheoverallmodelorwhenperformingapreliminary
energy analysis, which we touch on later in this chapter. You are given
similar parameters to define how you model a building, as well as options
to set building operating times (Opening Time and Closing Time) and an
Unoccupied Cooling Set Point parameter.
Revit MEP has several predefined options to model how the building, as
well as each space, is utilized, and each option has preset parameter and
schedule values for the internal loads. Parameters such as Area Per Person,
Lighting Load Density, Power Load Density, and Sensible Heat Gain Per
Person should all be familiar to you. You can use the preset values within
the program, or you can input more-accurate design load values based on
typical code-driven or industry-standard values.
You can access the Space Type Settings dialog box from the Properties
palette when a space is selected in your view. You can also access it from
within your Space Properties schedule by locating the cell in the Space
Type column (if used in your Space Properties schedule) for the space you
would like to modify and then selecting the ellipsis that appears next to
the current type name when you click in the field. If you click the People
or Electrical Loads button in the Properties palette when a space object is
selected, the default values within these windows are the values listed in
the Space Type Settings dialog box.
Figure 8.6
shows the dialog box for
establishing the occupancy and heat gain values, while

schedule settings accessed from the Space Type Settings dialog box.
