Metro Hippie elaborates on Passive House

Josh Foss most recently posted a great article on Passive Houses on his Metro Hippie’s Green Design + Lifestyle blog. Check it out, watch his GreenPrints webisodes and pick up a stylish Metro Hippie T-Shirt while you are at it.

Appleseed House — Passive House

During the last Appleseed House meeting, the group voted to make Appleseed a Passive House. We are now moving forward with schematic design and PHPP calculations.

Is the Passive House an experimental concept?

No. The Passive House has scientific and engineering validity as well as tried-and-true practical success. There are currently more than 6,000 Passive House buildings operating in Europe. The oldest one of them has been up and running since 1991. Many Passive Houses have been monitored and average overall performance proved to be right on the target of 15kWh per square meter and year. The Passive House Institute is in charge of the Passive House standard and it is being rigidly enforced and monitored. In 2008 there are 2 completed Passive Houses in the US that we are aware of, and about a half-a-dozen under construction. The European success and experience serves as a great resource for Passive House design in the United States. Think of it as a version 2.0, with a version 1.0 that has already been tested and used for 17 years.


What is the energy efficiency of a Passive House?

With cars, most people are familiar with the MPG (miles per gallon) rating system to determine their efficiency. Passive House standard captures performance of a building in a similar way by limiting the amount of energy used per square foot of living space in one year.

Green Lending Benefits

In a recent discussion with a lender we learned that underwriters are starting to catch up with green building. One area of interest is the thought of a bank looking at monthly energy savings (lower utility bills) as “income”. This means they can potentially qualify an applicant for an increased loan to cover increased up-front cost for green building design, practice, and renewable energies. We will make sure to investigate this further and post our findings.

On the drawing board: "Appleseed House"

Tim has been working on a pro-bono effort called the “Appleseed” house for a couple of months now. The Appleseed house is slated to be an affordable housing model home for North Minneapolis. The group behind the Appleseed house is currently working on a website. In the meanwhile, we’ll try to post some info on the progress on this blog.

Postcards under way

We mailed a batch of “open for business” postcards this week. Feel free to let us know if you think you should have gotten one but did not receive it.

What is a Passive House?

Representing today’s highest energy standard, the Passive House is a very well-insulated, virtually air-tight building that approaches “zero” energy. Instead of relying on “active” systems for heating, it primarily uses passive solar gain and heat gains inside from people, consumer electronics, appliances, etc.

Website live

It is official. The website is launched. Still a bit of tweaking here and there but we are very pleased with how it looks and what it offers. We look forward to YOUR comments. Please note that each entry has a comment link below. 

Re: Natural gas in MN up to 40% more expensive this winter!

Tim Eian makes a point to say that there has never been a better time to look to Passive House design to reduce the energy use of a building by up to 90%. The average Passive House homeowner would look at a projected $50 annual increase versus the aforementioned $500.

Natural gas in MN up to 40% more expensive this winter!

CenterPoint Energy expects we’ll pay 35 to 45 percent more than we paid last year. It means as much as $500 over 12 months for the average homeowner.

It's alive!

TE Studio is about to launch. We are now days away from the launch of your one-stop-shop for beautiful, resource-efficient building design. The boffins are working hard to put together the website that will eventually encompass this blog as well.
