Passive  house is building standard that is truly energy efficientcomfortableaffordable and ecological at the same time.
Passive House is not a brand name, but a construction concept that can be applied by anyone and that has stood the test of practice.

Yet, a Passive House is more than just a low-energy building.

  • Passive House buildings allow for heating and cooling related energy savings of up to 90% compared with typical building stock and over 75% compared with average new builds. In terms of heating oil, Passive House buildings use less than 1.5 litres per square meter of living space per year – far less than typical low-energy buildings. Similar energy savings have been demonstrated in warm climates where buildings require more energy for cooling than for heating.
  • Passive House buildings are also praised for their high level of comfort. They use energy sources inside the building such as the body heat from the residents or solar heat entering the building – making heating a lot easier.
  • Appropriate windows such as the designs manufactured by Hybrid Window Systems, with good insulation and a building shell consisting of good insulated exterior walls, roof and floor slab keep the heat during winter in the house – and keep it out during summer.
  • A ventilation system consistently supplies fresh air making for superior air quality without causing any unpleasant draughts. This is e.g. a guarantee for low Radon levels and improves the health conditions. A highly efficient heat recovery unit allows for the heat contained in the exhaust air to be re-used.
  • Hybrid Window Systems is one of the first companies in the UK dedicated to the manufacture, supply and marketing of hybrid windows and doors, which are becoming more popular across mainland Europe. The whole concept of hybrid is about exploiting the key benefits of each material and we have done so with the introduction of a number of product variants from KÖMMERLING’s revered System 76 platform.

    Aluminium as a building material ticks the boxes for building specifiers and architects, yet as a material it isn’t necessary the best insulator. The fact that it has slender sightlines and near limitless finishes is a major plus and the sector has enjoyed a renaissance in recent years.

    Yet once combined with a PVCu building material, the product possibilities and capabilities are unmatched.
