What is Passive House?

Passive House is a stringent building standard focused on maximizing energy efficiency.  It is a voluntary international building standard developed by the Passive House Institute (PHI), located in Darmstadt, Germany.

What is the Passive House Standard?

The PH Standard contains several performance requirements for new building construction and a similar standard for the retrofit of existing buildings. Passive House performance represents approximately 90% reduction in heating and cooling energy use and up to a 75% reduction in primary energy use from existing buildings. Passive House design was created to reduce the carbon footprint of the built environment and lower energy usage.

The Passive House standard also promotes building designs with comfort, safety and health for the occupants who reside and or work inside. Passive House is meant to lower energy usage and provide a safe, comfortable building/structure. Simply put, Passive Houses are the most comfortable buildings on earth.

When designing a Passive House, it is important to focus on minimizing heating and cooling loads through passive measures like building orientation, massing, insulation, heat recovery, passive use of solar energy, solar shading, high performance windows, elimination of thermal bridges, and incidental internal heat sources.  Because the building will be airtight, a low volume continuous supply of filtered fresh air is supplied to interior spaces and stale air is simultaneously removed – providing balanced and controlled ventilation with high-efficiency heat exchange.

A Passive House can be any type of building:  a townhome, condominium, apartment building, multi-use building, office building, manufacturing plant, home or school.  Regardless of usage, all Passive House buildings possess the following qualities:

Deliver fresh, high quality indoor air free of contaminates.

Very comfortable and consistent temperatures.

Require up to 90% less energy usage for heating and cooling demands from average existing buildigns.

PW Series

Our Passive House windows and doors deliver superior performance for these types of exceptional projects. The PW Series was specifically designed to meet the rigorous Passive House building standard. Triple pane glazing units are encompassed within a thermally broken wooden frame featuring a continuous layer of insulation, multiple air seals and durable aluminum cladding attached to the exterior of the windows for exceptional weather proofing. European hardware delivers smooth operation and modern style. The PW Series delivers the high performance required for Passive House certification without sacrificing on aesthetic sophistication and style.
