2. Simulating Renovation Measures

Learn how to analyze available renovation measures and simulate their impact on energy performance. This guide builds on the renovation plan created in the first guide and shows how to apply specific measures to see energy savings, cost calculations, and subsidy opportunities.

Step 1: Understanding Available Measures

After creating a renovation plan, the API returns an `available_renovation_measures` object containing all technically feasible measures for your building. Each measure category includes multiple options with different efficiency standards (KfW 40, 55, 70, 85).

Example: Available Heating Systems

From your renovation plan created in Guide 1, the `available_renovation_measures.heating_system` array will contain options similar to these (exact values depend on your building):

Step 2: Applying Measures to the Plan

Use the PUT endpoint to update your renovation plan with selected measures. This example applies wall insulation (KfW 70 standard) and installs an air-to-water heat pump.

Update Renovation Plan

Key Changes After Applying Measures

The updated renovation plan shows significant improvements compared to the baseline:

Step 3: Customizing Measure Costs

You can override the default cost calculations by providing custom costs in the config. This is useful when you have specific quotes from contractors.

Example: Custom Heat Pump Cost

{
  "planned_measures": {
    "heating_system": {
      "type": "heat_pump_air_to_water",
      "config": {
        "cost": 50000  // Custom cost instead of default €42,558
      }
    },
    "wall_insulation": {
      "type": "kfw70",
      "config": null  // Uses default cost calculation
    }
  }
}
