StyroFrame Passive System
Construct to PassivHaus Standards and save energy and money - typically 90% compared to existing housing.
The term 'PassivHaus' refers to a specific construction standard for residential buildings which use very little energy and have excellent comfort conditions and in both winter and summer.PassivHaus dwellings have:
- Compact form, orientation and good insulation.
- The shell of a PassivHaus is insulated to achieve a U-value better than 0.15 W/m2K; typical UK houses are constructed to 0.25 - 0.35 W/m2K.
- The orientation of the building is designed to take advantage of passive solar gains whilst reducing overheating so providing light, airy houses.
- The total energy demand for space heating and cooling is less than 15 kWh/m2/yr treated floor area, a typical UK house uses 55 kWh/m2/yr, older houses use much more.
- The total primary energy use for all appliances, domestic hot water and space heating and cooling is less than 120 kWh/m2/yr.
- Energy efficient windows and doors are installed.
- Energy efficient ventilation and clean air. A whole house ventilation system with highly efficient heat recovery filters the air to ensure excellent indoor air quality and provides energy savings.
- No Boiler - A PassivHaus does not need a traditional heating system or air conditioning. The small heating demand can be provided by using a small heater within the ventilation system (although there are a variety of alternative solutions).
- Energy saving household appliances provide energy savings and reduce costs.
