Kohltech has windows and doors that have achieved the rigorous certification standard of the Passive House Institute US. Below is an outline of the Passive House standard followed by the Kohltech products and options available to meet the standard.  A Passive House is essentially a super insulated house that exceeds most existing standards relating to energy usage. There are only 13 Manufacturers in North America and only 2 in Canada that have window products certified for this program. Kohltech is currently only one of 2 manufacturers in Canada to have certified door products.

Kohltech Passive House windows and doors will ship with a Passive House Institute US Certification label as shown in the sections below.

Passive House (Passivhaus) Certified Building Standards    Passive House Institute of United States logo

The term passive house refers to a rigorous standard for energy efficiency in buildings. The standard first originated in Germany in 1988 and has now spread across many countries worldwide. Estimates in 2008 of the number of Passive House certified buildings ranged from 15000 to 20000.

There are three rigorous standards that a building must follow to be eligible for Passive House Certification, along with several recommendations. The standards are as follows:

  • The building must be designed to have an annual heating and cooling demand as calculated with the Passivhaus Planning Package of not more than 15 kWh/m2 (4,2755 BTU/ft.; 5.017 MJ/sq. ft.) per year in heating or cooling energy OR be designed with a peak heat load of 10 W/m2 (1.2 hp/1000 sq. ft.)
  • Total primary energy(source energy for electricity, etc.) consumption (primary energy for heating, hot water and electricity) must not be more than 120 kWh/m2 (38,040 BTU/sq ft; 40.13 MJ/sq ft) per year
  • The building must not leak more air than 0.6 times the house volume per hour (n50≤ 0.6 / hour) at 50 Pa (0.0073 psi) as tested by a blower door, OR alternatively when looked at the surface area of the enclosure, the leakage rate must be less than 0.05 cubic feet per minute
  • The specific heat load for the heating source at design temperature is recommended, but not required, to be less than 10 W/m2 (3.17 BTU/h.ft2)
