Frequently asked questions

Short answers about the Bucha Passive House war resilience client story.

Was this Bucha house designed as a wartime shelter?
Story

No. It was designed before the war as a comfortable, all-electric, passive-level family house. The same decisions became protective when power, heating and communication failed.

What happened inside the house during the winter blackout?
Winter performance

The source account says the house started near 23 C, moved to about 21 C after the first week, then slowly approached 18 C and did not go below 16 C during roughly a month without active heating.

What helped protect the family?
Design

The result came from the whole design: continuous insulation, reduced thermal bridges, passive solar gain, useful thermal mass, controlled shading, airtightness thinking and measured daylight.

Can every passive-level house promise the same result?
Limits

No. Emergency performance depends on climate, starting temperature, airtightness, insulation continuity, windows, thermal mass, ventilation losses and project-specific engineering.
