IDC- Heat expenditure index

As of September 1, 2022, the heat expenditure index (HDI) threshold is set at 125 kWh/m2.year (450 MJ/m2.year).Beyond that, energy sanitation of the building is required.

​

Gradual decline of IDC 

• 222 kwh/m2.year (800 MJ/m2.year) from 2022 until December 31, 2026

• 180 kWh/m2.year (650 MJ/m2.year) from January 1, 2027 until December 31, 2030

• 153 kWh/m2.year (550 MJ/m2.year) from January 1, 2031.

 

Sanitation general is planned see useful link:

Residential- The villasare also affected

Previously exempted from calculating the annual IDC of their building, owners of residential buildings supplied by a single heating plant and comprising fewer than 5 heat consumers - mainly villas - are now also subject to this obligation. They will therefore have to fill in the first IDC calculations as of June 30, 2024 for the 2022-2023 heating period.
