Mid-winter is when buildings show you exactly how they're performing.
The rooms that never quite warm up. The windows that run with condensation overnight. The floors you avoid in bare feet until midday.
In a Passive House it's different — not dramatically so from the outside, but different to live in. The temperature is consistent room to room. There's no cold from the windows. The floor is the same temperature as the air.
These are things you feel rather than measure. But they're the result of decisions made at design stage — orientation, insulation, airtightness, windows.
Winter is a good time to pay attention to how your building is actually performing.
