one doesn't have to have a passivhaus standard of building to use forced air heating. The comments about insulation and airtightness apply to all houses, regardless of the heat delivery system. Forced air is unusual in Europe but is the norm in North America, mainly due to the need for air conditioning in the summer. Air leakage doesn't affect forced air heating systems more than hydronic - it's equally bad in both/all cases. Of course, the nice thing about an air delivery system is that humidity control can be incorporated into the system, should it be required (plus air conditioning too for those climates that need it).

Paul in Montreal who lives in an old house that's certainly not passivhaus standard but who does have forced air heating (albeit supplied by a GSHP).]]>
