Thinking about building or remodeling a home, or want to know more about energy efficient technology to reduce your carbon footprint as well as your heating and cooling bills? Tim Eian has focused his architectural skills on incorporating the latest technology in energy efficient new and remodeled homes, which use a tiny fraction of most houses.

This presentation at the North Hennepin Community College highlights the “MinnePHit House” project in South Minneapolis—a deep energy reduction project that turns a 1935 house into a Passive House home.

More information can be found on the North Hennepin County Community College website.

Date: 4/25/2012

Time: 10 – 11 AM

Location: North Hennepin Community College CLA 133

Energy Independence with Passive House

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.”

Passive House ≠ Passive Solar

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.
