Passive houses

Passive houses have an intuitive name, in fact, those are houses who have a low impact on the environment. Those are buildings who are not only made of design (aesthetically speaking) but also of the highest technology.

Recently passive houses have been highly considered in big cities as Seattle, but also in regions as Oregon.

What makes a good Passive House?

As listed in a well-known magazine this is what makes a passive house:

  1. Well isolated windows and doors.
  2. Efficient water system, heating and lighting.
  3. A building envelope, to stay fresh in summer and hot in winter.
  4. Mechanical ventilation to transfer air in&out of the house during seasons.
  5. A software made for reducing energy losses, called PHPP. But I think this is a technical component for those who want to enter the Passive House Community in America.
  6. A certification that proves that your house is green.

How can I make my normal house, a little more sustainable?

As you have seen on the other list, having a sustainable house is not only made of high-tech expensive renovation, but also of little touches that can make the difference:

  1. If you have your own propriety building an envelope shouldn’t be so difficult, it has been made also in my house and it shouldn’t be too expensive. If you don’t have too much money to spend on it try to envelope or protect just the walls where it gets hotter, or the areas of your house where it gets colder in winter ( not everybody lives on California!).
  2. Change your lighting to new LED light bulbs, which I know are more expensive than the old ones, but they also resist longer, and they consume only 1.87$ per fixture vs 13.35$ per fixture of the halogen bulbs.
  3. This is a tip for those who are a little bit broke, or are students, or don’t have their own house: try to use fans instead of conditioned air when you can, it’s gonna be cheaper and you’re not gonna have to worry about your health!
  4. Change your old appliances with A+ new ones, they waste 80% less than the old ones!
  5. Use rechargeable batteries instead of normal ones in your house! Low-cost and good for the environment.
