Standard at construction

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

Likely to lose indoor heat quickly in winter unless the envelope was upgraded later.

The plausible construction-year range crosses a thermal-regulation boundary. Actual performance may correspond to either period.

Standard at construction

No general thermal standard — The building predates Spain’s general requirements for limiting heat loss through walls, roofs and windows.

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.
