The passive house?
« on: 18 Apr 2010, 11:24 am »
Anyone heard about or have passive homes?  See:

Here's another link:

The idea is that you build an incredibly well insulated and air tight house.  Think R40+ walls and R80+ roofs.  They use very energy efficient windows (very low u value) and orient the home on the land to take advantage of natural heating and cooling based on sun paths. 

Because they're so sealed, they have to use air recirculation and intake systems.  I'd write more, but I have a toddler attacking me!  (She likes the smiley faces, though.)

I use my drafty windows to bring in fresh air...

This year I want to take advantage of the rebates in the US to get new energy efficient windows

Passive Houses are quite common in Germany and Austria where energy costs are very high. But they are not yet well known in North America.

Here's a few sites I was viewing just the other day....ran a Google search for "Green Homes" and "Eco Homes".....

Some interesting video's....

When we were shopping for homes in Durham, NC, we looked at a couple of "passive solar" places.  It seemed they had all been built by the same designer sometime in the 70s.  It seemed like a great idea, but the fad had never caught on.

There were some features of these homes that could easily have been unappealing.  I loved the way that almost a whole side of the house would be covered with windows.  But the downside was that the other side of the house tended to be devoid of natural light.  These days, use of things like solar tubes could alleviate some of these concerns. 

Then there was the choice of flooring material.  Desirable materials are those that will stay cool when you want the house to be cool, and will retain heat when you want the house to be be warm.  That usually means stone or brick or tile.  Now, I like many natural stone floors.  But at least one place we looked at had brick floors, which was much less appealing.  And let's face it, even the finest slate is unlikely to be an audiophile's first choice for flooring.

HGTV is running a sweepstakes on a "green" home giveaway in Massachusetts. But don't enter it because I want a better chance to win it myself.
