Certified Passive House

The Passive House standard is one of the world's most aggressive, proven, voluntary approaches to radical energy reduction, assured indoor air quality, durability, and thermal comfort in the world today. The Passive House standard has roots in Sweden, Germany, Canada and the US. 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.

U-Value

0.21-0.28

A U-Value tells you how thermally efficient a product happens to be, lower numbers indicating better insulating properties

Air Leakage

0.20

Air leakage, or air infiltration, is the amount of air that passes through cracks in the window assembly, as well as the amount of air that leaks through the window frame due to window installation and sealing failures. The more air that can leak through a window, the less energy-efficient that window will be.

Visual Transmittance

0.48

To take account of different tastes and architectural styles, modern window technology can be realized not only in white but also in GEALAN-acrylcolor® or with a décor or wood-grain foil.

Heat Gain
Coefficient

0.24

The fraction of solar radiation admitted through a window, door, or skylight -- either transmitted directly and/or absorbed, and subsequently released as heat inside a home. The lower the SHGC, the less solar heat it transmits and the greater its shading ability.

Energy Efficiency

VERMAK Windows balances energy efficiency, affordability, and versatility. With our windows, any building can be an efficient one - from residential to commercial. Create a flood of daylight while achieving one of the highest thermal performances on the market, and balance costs too.

Green building is no longer the trend, but the ethical and smart way to build. Through high performing windows and doors, you can secure savings on the ever-rising cost of energy, decrease your maintenance costs, and gain energy tax credits and/or funding.

Passive House certified buildings meet a set of design principles used to attain a rigorous level of energy efficiency within a specific quantifiable comfort level - or in other words maximizing gains, and minimizing losses. Energy consumption for passive buildings is miniscule compared to conventional buildings, thus securing considerable savings on energy costs and increasing your ROI.


The passive principles can be applied to any type of structure, from high-rise apartment buildings, to hotels, to churches, and beyond - and for new construction or retrofits. Energy efficient windows are considered a core pillar in Passive building, and VERMAK has been at the forefront of the U.S. Passive movement since our inception.
