One of the frequently asked questions I get about Passive House is its potential for going off the grid. I summarized different levels of energy independence in a Google knol.
Passive House buildings use very little energy to begin with. Therefore, it is a lot easier to utilize renewable energy sources such as solar or wind to offset a Passive House’s energy use. Renewable systems are much smaller than they would have to be for standard construction buildings, which saves investment cost.
Many different energy sources are a viable option for Passive House because of tis inherently small energy footprint. This make Passive House buildings very flexible and future proof.
One of the key goals of Passive House is to insulate the owner from an uncertain energy future. The buildings we build now will likely be around for 50, 100, or more years. Therefore, they will have to function in an era where the fuels we commonly use now may no longer be viable. That point may be reached long before the actual resource is consumed, as pointed out by former Saudi Oil Minister Sheikh Yamani in 1973: “The stone age didn’t end because we ran out of stones.”
Anytime I speak to people about Passive House there seems to be some confusion with the Passive Solar Design ideas from the late 70s. I created a quick outline to compare the two and show which is what: Passive House vs. Passive Solar Design at Google knol.
Join us during the 7th international Passive House Days on Friday through Sunday. We will open the Passive House in the Woods for public viewing from 10 am to 4 pm each day. Gary Konkol (owner) and Tim Eian (TE Studio) will be on site to answer your questions and demonstrate how the home functions with every day use. We look forward to seeing you in Hudson.
Mary James at Lowcarbonproductions just published her second book on Passive Houses in the U.S. called “Recreating the American Home”. I am happy to announce that the Passive House in the Woods project is one of the feature projects in the book. You can find more info and purchase the book here.
I’ll be presenting the Passive House in the Woods at the 5th North American Passive House Conference on Saturday, November 6th 2010, time t.b.d.
You can find more info and register for the conference at the Conference Website.
All my upcoming and past speaking engagements can be found in the Portfolio/Lecture section of this website.
The U of M’s Bell Museum in partnership with the Center for Sustainable Building Research invited us to participate in their latest exhibit, Sustainable Shelter—Dwelling within the Forces of Nature. The exhibit will show the many ways that animals and humans create shelter, and explain how shelters relate to the environment. Doors opened this past weekend and the exhibit will be on through May 15th. The grand opening is November 11. Find the CSBR’s press release at this link.
