Passiv Haus
(Videos are loading, please be patient if this page is slow)
A dwelling that achieves PassivHaus standards will typically include the following details:
- Super levels of insulation with very minimal thermal bridging
- High utilisation of solar energy and internal gains
- Excellent level of airtightness
- Whole house mechanical ventilation system with heat recovery
Space heating is often assisted with that generated as a by product of running electrical equipment, hot water cylinders, hot pipe work, solar gains and that given off by the inhabitants. A small heating element, often integrated into the mechanical ventilation system can also assist demand. Cooling can also be integrated in this way though it is not prefered as high insulation, high thermal mass designs should adequately manage this problem.
For Europe (40o - 60o Northern latitudes), a dwelling is deemed to satisfy the PassivHaus criteria if:
- The total energy demand f or space heating and cooling is less than 15 kWh/m2/yr treated floor area;
- The total primary energy use for all appliances, domestic hot water and space heating and cooling is less than 120 kWh/m2/yr
