Intus Windows, a leader in energy efficient windows, says that there are differences between passive house designs and net zero house designs.

NEW YORK, NEW YORK, USA, September 30, 2014 /EINPresswire.com/ -- According to Aurimas Sabulis, managing director of Intus Windows (http://www.intuswindows.com/), a worldwide leader in the manufacture of energy efficient window products, a “net zero” or “zero energy” house is one that essentially uses the same amount of energy, on an annual basis, that is produced on the site.

“A net zero home is achieved through the use of PV solar panels on site to satisfy the home’s electrical needs,” Sabulis says. “Of course, these homes still produce greenhouse gases because, at night or when the sun isn’t shining, they use conventional grid electricity as the main energy source to power the home.”

On average, according to Sabulis, most net zero homes still get at least 50 percent of their energy from the grid at night or when the sun isn’t shining. This is offset during sunny days when the unused power generated by the PV solar panels is sent back to the grid for use by other utility customers.

“On the other hand, a passive house is a home that is designed to be incredibly energy efficient,” says Sabulis. “It is designed to use the least amount of electricity and fossil fuels possible, to heat and cool the home.”

Sabulis says that passive house design buildings are airtight (<0.60 ACH @ 50 Pa) and the annual heating requirement is ≤15kWh/m2/year (4.75 kBtu/sf/yr).

“It requires the use of energy efficient triple pane windows like the ones we produce here at Intus Windows,” Sabulis explains. “Passive solar energy from the sun is captured by south facing windows during wintertime, to help heat the home, instead of relying on active systems like electricity and/or fossil fuels.”

This creates a home, he says, that can save up to 90 percent of space heating costs and provides a very comfortable indoor air environment.

“Designing and building a passive house or a net zero structure are great goals to aspire to,” Sabulis says. “Building experts say that homeowners should strive for passive house standards but should at least attain a net zero design, because it is easier and more cost effective. The bottom line is that the more energy efficient a home is, the less energy it will require to heat and cool it.”
