Building renovations
Renovation class
O — Total reformA major reform was recorded for the affected part, below integral rehabilitation.
Renovation scale
Recorded coverage: approximately 3%The renovation marker applies to a small, isolated part, based on its share of the constructed area recorded in Catastro.
Some homes or building sections may have been substantially modernised while the rest may retain older characteristics.
Do not assume that insulation, windows, wiring, plumbing, lifts or common areas were all renewed. Ask which areas were affected and check permits, invoices and inspection records.
Building standards
General minimum housing requirements were in force.
Noise Insulation estimated
Voices, television and music through separating walls and floors
How requirements evolved
Sound insulation depended mainly on construction type and any rules applicable to the building.
Separating elements: R ≥45 dBA
Historical benchmark — not an estimated value for this building.
Historical and current acoustic values are not directly comparable.
Protected rooms: DnT,A ≥50 dBA
Footsteps, moving furniture and objects falling on the floor above
How requirements evolved
Sound insulation depended mainly on construction type and any rules applicable to the building.
Impact noise: Lₙ ≤80 dBA
Historical benchmark — not an estimated value for this building.
Historical and current acoustic values are not directly comparable.
Impact noise: L’nT,w ≤65 dB
- Built in 1972
- Plausible year range: 1972–1972
- Construction-year confidence: high
- Standard cadastral category — shown as context, not used to change the rating
- Building chronology: consistent
Before NBE-CA — The building predates Spain’s first general acoustic standard, so separating walls and floors were not designed under a common national sound-insulation framework.
Expected range from Construction Profile chronology and regulation period; actual wall, floor and building-services performance has not been measured.
Thermal Insulation estimated
How well the original building envelope is likely to retain indoor heat
How requirements evolved
Thermal performance depended mainly on wall, roof and window construction.
Roof ≤1.40 W/m²K
Light façade ≤1.20 W/m²K (≤200 kg/m²)
Heavy façade ≤1.80 W/m²K (>200 kg/m²)
Historical benchmark — not an estimated value for this building.
Roof ≤0.40 W/m²K
Walls ≤0.49 W/m²K
How well the building is likely to limit summer heat from direct sunlight
Likely to lose indoor heat quickly in winter unless the envelope was upgraded later.
- Built in 1972
- Plausible year range: 1972–1972
- Construction-year confidence: high
- Building chronology: consistent
- Standard cadastral category — shown as context, not used to change the rating
Before general thermal regulation — The building belongs to a period before thermal insulation became a general requirement for new housing.
Summer protection is a comparative building-level estimate. Window size and orientation, external blinds, ventilation, the exact apartment floor and air conditioning are not yet known.
Expected original envelope standard. Current windows, facade and roof insulation, thermal bridges and undocumented works are unknown.
