What is Passive House?
A Passive House uses a specific set of design principles to obtain aggressive energy efficiency and comfort and reduce the ecological footprint of a building. Following a standard released in 2015, these residential, multi-family and commercial buildings use only small amounts of energy for heating and cooling. Learn what goes into the coveted Passive House Institute United States (PHIUS) certification.
Requirements of Passive House Windows & Doors
Extreme Energy Efficiency
The Passive House Standard places a heavy emphasis on continuous insulation throughout the entire building envelope — without any thermal gaps or bridges to provide ultimate comfort. For windows and doors on a Passive House project, this places more emphasis on the glazing and insulation of the unit, including its U-Factor and R-Value. The U-Factor measures the rate of heat transfer through a window or door.
The lower the U-Factor, the better the insulating properties of the unit or glazing system. R-Value measures how well insulation keeps heat or cold from entering and exiting the home — the higher the value, the better. Our dual- and triple- glazing systems leverage panes of Low-E glass with the insulating space filled with argon or krypton gas to optimize energy efficiency.
As a key component in a building envelope, windows and doors are a critical decision in Passive House design. Our products are engineered for exceptional performance, helping to eliminate drafts and leaks in the building envelope. Pella products are tested and rated at or above industry standards to reduce air infiltration. Another key component to the performance of a window is proper installation; the perimeter seal between the wall and window frame needs to be complete.
