Key variables in the outcome of a systems analysis are
00:07
the method or mode used to generate the energy model.
00:10
The materials assigned and the material thermal properties.
00:15
When creating an energy model from a linked architectural model,
00:19
the available material choices and material thermal properties will
00:23
depend upon the way the architectural model has been created
00:27
and the material thermal property choices made
00:30
in the advanced energy settings of rev.
00:34
In this project,
00:35
we will recap on the available options for
00:37
generating the energy model and review the available
00:40
options for material thermal property selection along with
00:44
the order of priority for application during analysis,
00:49
ensure the view is set to H VAC floor plans, 01
00:54
H VAC plan.
00:57
Let's first review the mode options in the energy settings.
01:04
The energy model can be created by either using
01:07
the building elements from the detailed architectural model,
01:11
conceptual masses.
01:12
If they've been used to define the building envelope of the architectural model
01:17
or from rooms or spaces,
01:21
whichever method is used,
01:22
material thermal properties will be applied to the resulting energy model
01:27
and can be controlled to affect the outcome of the analysis
01:32
set. The mode option to use conceptual masses and building elements.
01:36
Then select the edit button under advanced and other options
01:44
in the material, thermal property section. Select edit against conceptual types
01:51
for mass model elements such as walls, floors and roofs.
01:55
The user can determine the construction material that
01:58
will be used as the basis for analysis
02:02
for each mass modeled element type. The construction material can be changed
02:07
from the dropdown menu against mass exterior wall. Review the available options
02:17
then select OK to close the window,
02:22
select the small gray button against schematic types.
02:28
The schematic type shown here under the category column provide
02:33
the option to override the materials previously shown in conceptual types
02:39
where there is a check in the override column.
02:41
This is the material that will be used in the analysis for that category.
02:46
As with conceptual types, the materials for each category can be changed
02:52
from the dropdown menu against exterior walls, review the available options,
03:00
then select OK to close the window.
03:04
Finally, there is an option to place a check against detailed elements
03:09
where the linked architectural model contains
03:12
physically modeled elements such as walls,
03:14
floors, doors, windows and roofs
03:17
and those elements have material properties defined
03:20
when this option is selected,
03:23
these material thermal properties will take priority over
03:27
conceptual types and schematic types for the analysis.
03:32
Regardless of how the energy model was created,
03:35
all three options can be set with the order of priority being detailed elements.
03:41
Schematic types, then conceptual types,
03:46
setting the mode to the recommended use,
03:49
conceptual masses and building elements will cater for both
03:53
types of elements in the linked architectural model,
03:56
conceptual masses and physical building elements
04:01
use the material thermal property section of the energy settings to suit the
04:06
type of elements used in the architectural model and the level of model development
04:11
as model development progresses,
04:13
changes to the material thermal properties
04:16
will provide ongoing and comparative analysis results
04:20
that can be used to drive the design decisions in your project.
