What is a Passive House?

This definition is taken from the Passive House Institute US web page.

"A Passive House is a very well-insulated, virtually air-tight building that is primarily heated by passive solar gain and by internal gains from people, electrical equipment, etc. Energy losses are minimized. Any remaining heat demand is provided by an extremely small source. Avoidance of heat gain through shading and window orientation also helps to limit any cooling load, which is similarly minimized. An energy recovery ventilator provides a constant, balanced fresh air supply. The result is an impressive system that not only saves up to 90% of space heating costs, but also provides a uniquely terrific indoor air quality."

75th Post – Passive House Conference

Week 20 of Construction
Wow, what a week.  There was just a little done in our home itself, but we were trying to prepare our PH for the Passive House Tour -- just cleaning up the building site and leveling out the walkway so people wouldn’t trip and so on.

On Thursday, they had an open forum for anyone interested to come and learn about passive houses and to look at posters of what people are building.  Ethan and I were there to field questions about our build/poster and looked at the other projects.  It was very interesting. 

On Friday, there was a dinner and Ted and I were able to talk with others who were at the conference.  If you are thinking of building a passive house or are a builder, coming to a conference like this would give you great information.  Yes, it may cost to come to the conference, but the cost of building a home is a large investment and in the long run coming would save you money.  I was impressed about the give and take and people willing to share their experiences with what works and what doesn’t.

On Sunday, they had a passive house tour and our home was one of five homes open to those registered.  We had around 140 people who came through and we had great feedback!   Four of us spoke and gave information in the beginning and then we opened it up for questions and answers.  I also had a slideshow of the construction, like the one on the side of my blog.  The plans were out and people wandered around and even some adventurous individuals ventured into the mini basement to look at the ventilation and heating system.

It was great to show our passive house and how we are building a little differently then other passive homes.

  1. I have a question, what is the bulk of your air sealing? Much appears to be the layer of polyurethane on the interior of the outside wall. Is this meant for air sealing? Do you have plastic sheeting anywhere?
