The Interventions page allows you to evaluate, compare, and manage decarbonization measures across your portfolio. It combines intervention configuration tools with interactive analysis capabilities, including a heat map and advanced filtering.
From this page, you can tailor interventions to your portfolio, assess their performance across buildings, and segment results based on both intervention-level and building-level criteria.
To access Interventions, click Interventions on the sidebar. This opens the Interventions dashboard.
The Interventions page includes two primary sections:
- Analysis – Visualize and compare intervention performance across buildings.
- Definitions – Create, edit, and manage intervention assumptions.
You can switch between these views using the tabs at the top of the page.
Definitions
The Definitions tab is where intervention configuration occurs.
From this view, you can:
- View all current interventions being modeled.
- See which model parameters are impacted.
- Review the default cost of each intervention.
- See whether the intervention is set to preserve baseline performance (i.e. only apply the intervention if it improves baseline energy performance).
- Create and edit Custom Interventions.
This tab controls how interventions are defined and applied across the portfolio.
Creating a New Custom Intervention
Click + New intervention to launch the Custom Intervention Wizard.
Step 1: General Information
Provide the basic details:
- Name of the intervention.
- Default cost ($ per unit of floor area).
- Utility incentive (if applicable)
- Service life, in years (if applicable)
- Change in maintenance cost (if applicable)
The financial metrics above directly influence the calculated Net Present Value and Marginal Abatement Cost results.
Click Next → to proceed.
Step 2: Model Parameters
Here, you define the technical adjustments for the intervention.
You may optionally select or unselect Preserve baseline performance.
- If selected: the target values defined for this intervention will only be applied when they improve a building’s baseline conditions.
- If unselected: the intervention will be applied regardless of whether it worsens baseline conditions.
To modify target values:
- Click + New target value.
- Select the model parameter you would like to adjust.
- Choose the appropriate action.
- Enter the target value or adjustment.
- Repeat as needed for additional parameters. You can define multiple target values within a single intervention.
You can set target values for a wide range of model parameters, including:
- Envelope & Infiltration: Wall assembly R-value, Roof assembly R-value, Window assembly U-value, Window SHGC, Infiltration rate
- Lighting & Equipment: Lighting power density, Equipment power density
- Schedules: Lighting, Equipment, HVAC, Heating/Cooling setpoints, Ventilation
- Mechanical Systems: Heating/Cooling systems, Fan pressure drop, Economizer, Maximum humidity level, Heat recovery effectiveness, Ventilation rate, Fan minimum turndown, Supply air reset
Each parameter supports different Actions, such as:
- “Set Value to” – Assign a specific value
- “Percent” – Increase or decrease by a percentage
- “Shift” – Adjust a numeric value up or down
- “Substitute” – Replace a schedule based on its current (baseline) condition
Example: Increase Wall Assembly R-value by R-5
- Click New target value
- In the dropdown menu, select “Wall assembly R-value”
- For Action, select Shift
- For the secondary Action, choose Increase by
- Enter 5 to represent a 5-point R-value increase
Click Next → to continue.
Step 3: Description
Add a short description to document the purpose or technical assumptions behind the intervention. This is helpful for team members reviewing or editing the intervention later.
Click Save and evaluate to apply the intervention across the entire portfolio. The results will be visible in each building’s Building Details page.
Applying Custom Interventions to Existing Buildings
If a building was added before you created the Custom Intervention, and you would like to see the intervention on the decarbonization timeline:
- Go to the Building Details page.
- Scroll to the Applied Interventions table.
- Click the Edit icon for the Custom Intervention.
- In the popup, check Apply intervention to building.
The Decarbonization over Time chart will update to reflect the newly applied intervention.
