Transcript
00:04
The Energy Optimization Panel in Revit provides clear guidance and directions to set up better analyses for the entire design team.
00:12
The energy analytical model powers Energy Optimization
00:16
and is a special form of geometry used for energy simulation engines by architects and sustainability specialists.
00:23
The model is a lightweight representation of the building that tracks input data for different types of analyses,
00:30
such as energy and carbon analysis.
00:33
In this example, an energy analytical model has already been created.
00:38
Two major components of the model include analytical spaces and analytical surfaces.
00:45
Analytical spaces, represented in blue in the model,
00:49
are discrete volumes (or masses) of air that experience heat loss or gain.
00:54
These heat changes are due to internal processes like occupancy, lighting, equipment, and HVAC,
01:01
as well as heat exchange with other spaces and with the exterior environment.
01:05
Each space contains a set of analytical surfaces that determine the volume of the space.
01:12
Open the Visibility/Graphic Overrides dialog by pressing VG on your keyboard.
01:18
Then, open the Analytical Model Categories tab.
01:23
Enable Analytical Surfaces.
01:26
The model updates and displays the analytical surfaces as geometric elements representing building elements,
01:33
like floors, ceilings, interior walls, and exterior walls.
01:39
Also, they are color-coded based on the building elements they represent.
01:44
Importantly, these surfaces are the paths of heat transfer to or from each space.
01:51
They include surfaces between interior spaces and the external environment.
01:57
Revit offers different ways to specify material thermal properties in the creation of the Energy Analytical Model.
02:04
These methods can be used in combination with one another to suit different stages in the design process,
02:11
levels of detail, and user preference.
02:14
To access material thermal properties, from the Analyze tab, Energy Optimization panel,
02:20
select Energy Settings.
02:22
Then, in the Energy Settings dialog, scroll down, and under Advanced, next to Other Options, click Edit.
02:30
The Advanced Energy Settings dialog opens.
02:34
Navigate to Material Thermal Properties, where you can access the Conceptual Types, Schematic Types,
02:40
and Detailed Elements options.
02:43
Your choices here control which types are included in the energy analysis, again depending on the design stage.
02:50
The Conceptual Types determine the thermal properties used for energy analysis
02:55
when thermal properties are not otherwise defined using schematic types.
02:60
To configure the conceptual types, click Edit.
03:04
Schematic Types define thermal properties for building elements during schematic design.
03:09
When this is enabled, the schematic types override the conceptual types.
03:15
Then select the specific element categories for which you want to use schematic types.
03:21
Lastly, when Detailed Elements is enabled,
03:24
the detailed elements override both the conceptual types and schematic types.
03:29
This should only be used where the material thermal properties have been specified for building elements
03:35
as defined in the Materials Library.
03:37
Therefore, enable this only when you are completely aware of all material thermal properties in the model,
03:44
and you are confident that they represent real construction properties for energy simulation.
03:49
Understanding the different aspects of the energy analytical model
03:53
allows you to perform accurate analysis for whatever stage your design is in.
