What is Passive House?

Passive House is a quickly emerging standard that requires buildings to use an extremely small amount of energy for their heating and cooling needs. This method was first developed in Germany and has since spread throughout Europe and North America. Passive Houses are very well-insulated and virtually airtight. These buildings require extremely low amounts of energy for heating and cooling. Heating requirements are primarily satisfied through passive solar gain and the energy produced by people and electrical equipment. The Passive House method of construction has the potential to dramatically reduce society’s energy consumption, and therefore radically reduce our carbon emissions.

What is a Passive House Window?

Most energy-conserving windows fall into the catagory of double glazed windows. Zola’s passive house windows have three panes of glass, significantly increasing the insulating power. Passive Houses must be extremely air-tight and well-insulated, and it is impossible to achieve this in a building without extremely well crafted windows.

Passive House windows are:

  • Airtight
  • Highly insulating
  • Available with high SHGC glass
