Energy retrofit is the highest-impact intervention a housing association can undertake on its existing building: it cuts consumption by 40% to 70%, dramatically improves interior comfort, increases property value, and provides access to Next Generation funding with coverage of up to 80% of the cost.
At Estudio Metropolitano we approach energy retrofitting with an integrated view of the building: before drafting any project, we start from the IEE and the LEE, which we also produce.
We work on every element of the thermal envelope: facades with ETICS systems, roofs, inner courtyards, thermal bridge elimination, and window replacement.
Initial diagnosis
IEE + LEE + current energy certificate. Without this starting point, no effective intervention can be planned, nor any funding accessed.
Preliminary design + simulation
Action proposal with before/after energy simulation.
Technical project
Basic and Execution Project with full construction details.
Permits and works
Permit processing and grants. Construction supervision. Final settlement.
- External (ETICS) insulation on facades.
- Roof insulation and thermal bridge elimination.
- Replacement of exterior joinery.
- HVAC and DHW system upgrades.
- Processing of Next Generation grants (40-80%).
When is energy retrofitting mandatory?
It is not mandatory, but highly recommended for buildings prior to CTE 2006.
Do Next Generation grants cover the entire intervention?
Grants can cover between 40% and 80% of the cost depending on the degree of energy savings achieved.
What does energy retrofitting typically include?
External insulation (ETICS) on facades, roof insulation, replacement of exterior joinery.
Are prior IEE and LEE required?
Yes, to access most grants it is essential to have the Building Evaluation Report and the Existing Building Book.
Does utility supply need to be cut during the works?
No. External interventions (ETICS) are carried out without residents having to leave their homes.
