What Is a Passive House or
A Passive House or Building
maintains a rigorous standard for energy efficiency in a
building. This standard can virtually eliminate the need for
a carbon fuel-based heating and air conditioning system.
How It Works
A passive building design
incorporates an extremely well-insulated, air-tight
building envelope combined with systems to control air
quality and indoor temperature and comfort. The insulation
requirements for the various building components and the
heating and cooling loads are calculated with a very
accurate building modeling software, PHPP - Passive House
The Passive House Standard can
only be met by using super-insulated window and door systems
and super efficient heat recovery air exchangers. The result
is a building that will require up to 90% less energy for
heating and cooling and will maintain a better indoor air
quality than a traditional building. The building is
primarily heated by passive solar gain from windows and
doors along with internal heat gain from people and
electrical appliances, etc. The summer cooling load is
controlled by smart low-e coatings in the glass, window
orientation and shading. Any remaining heating or cooling
demands are covered by a very small back-up heating source.
ENERGATE® WINDOWS and DOORS provide the best passive house
performance available in fenestration products today. This
will allow for more design flexibility and could potentially
save costs for insulation elsewhere in the building
envelope. ENERGATE® offers a wide range of products
including entrance doors, side doors, balcony doors and lift
& slide patio doors with the same super high performance as
the windows. All products come in a wide range of stylish
designs and colors.
ENERGATE® - the choice of the future.

in the United States. ENERGATE® windows and
doors were installed in both the winning
houses at the Solar Decathlon 2007 and 2009
in Washington, DC.
