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.

Likely to lose heat relatively quickly and require more heating than newer buildings.

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

  • Plausible year range: 1975–1985
  • Construction-year confidence: medium
  • Building chronology: consistent
  • Above-average cadastral category — shown as context, not used to change the rating
Standard at construction

Decree 1490/1975 — Spain’s first broad energy-saving rules began limiting heat transmission through the building envelope, but requirements were modest by modern standards.

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.
