00:03
In Revit Insight, once you create a new metric, you can use it to create new custom metrics.
00:09
The metric can be embedded within existing metrics formulas,
00:13
or you can use it to build an entirely new formula.
00:16
In this model, custom metrics have already been defined and can now be used to create new metrics.
00:23
From the navigation bar, select Manage Metrics to open the Manage Metrics dialog.
00:28
The custom metrics are listed under My Metrics, and they also appear within the data tree, under the Metrics category.
00:36
As an example, suppose you want to understand the impact of renewable energy on operational energy.
00:43
The easiest way to do this is to edit an existing formula.
00:48
From the list of Get Started metrics, select Operational Energy.
00:52
The Operational Energy metric is calculated by EnergyPlus,
00:57
an open-source simulation engine,
00:59
for comprehensive energy analyses across various building types.
01:03
By meticulously considering inputs like building geometry, materials, occupancy schedules,
01:10
HVAC systems, and weather data,
01:13
EnergyPlus enables accurate predictions of energy usage,
01:17
facilitating informed decisions to enhance energy performance.
01:21
Note that when the Operational Energy formula appears, in the information area,
01:26
the Unit Type and Display Unit are set automatically.
01:30
In the toolbar, click Copy, then enter the Name “Operational Energy–PV-Array” and a Description of “Net Energy”.
01:39
Since the original formula is set to calculate the total amount of energy used over the lifespan of the building,
01:45
by subtracting the renewable energy from it,
01:48
the result will be its net energy demand.
01:50
To edit the formula, operators are added so that Renewable Energy is subtracted from the electric and fossil fuel energy.
01:58
Click Evaluate formula, and then click Add to create the metric and add it to the My Metrics list.
02:05
You can repeat these same steps to create more new metrics.
02:10
In this case, the Operational Carbon metric is selected,
02:14
which automatically sets the Unit Type and Display Unit to Mass Equivalent and kgCO2e.
02:21
The metric, named Operational Carbon (-PV), is being created to represent Net Operational Carbon.
02:29
To build the formula, again, the Renewable Energy metric is used—this time, at the Electricity Emissions Rate—to subtract
02:39
the renewable energy carbon from the total operational carbon.
02:43
This results in the net operational carbon over the building lifespan.
02:49
Click Evaluate formula, and then Add.
02:57
Finally, a metric like the default Total Carbon metric is created to represent the net total carbon.
03:04
In this example, instead of starting with the existing formula,
03:08
Add is selected to demonstrate building the entire formula.
03:12
This metric is named “Total Carbon (-PV)”, with a Unit Type of Mass Equivalent and the Display Unit set to kgCO2e.
03:23
The formula is then built by subtracting the Embodied Carbon metric from the previously created Operational Carbon (-PV) metric.
03:32
Evaluate the formula and click Add.
03:35
You can now use these custom metrics to configure custom dashboards, examine different scenarios, and optimize your design.
