Passive House – Behind the scenes…

It’s been quiet here on the Exsting Resources blog, but that doesn’t mean that Passive House has had nothing going on!  I attended the North American Passive House Conference in Portland, OR earlier this month and was both energized and exhausted at the end of it.  It was truly great to meet others in the Passive House community and hear what they are doing.

I attended some great sessions and came away with so many ideas it’s hard to figure out which way to go next.  One of the sessions was on Passive House schools in Europe and the speaker, Ludwig Rongen, was particularly inspiring.  I took notes on his talk as fast as I could and plan to provide information on some of the projects he mentioned on the Passive House Commercial site of the http://PassiveHouseCentral.US community in the near future.

I need to get back over to the Seattle Passive House for another update and let you know how that is wrapping up.  I also want to give you a heads up for what is coming up after the first of the year for this blog.  I am living in a 1968 rambler and the homeowner has asked me to work up a plan to convert it to Passive House.  I don’t know if if will go all the way through to construction, but it will be a good exercise AND and excellent opportunity to blog about how you start with an Existing Resource like a 1968 Rambler, figure out how it was put together, and then figure out how to convert it to Passive House.  I think it should be a lot of fun.

When I do start the Rambler Retrofit blog project I want to explore a variety of ways and materials to use to test out in the PHPP and THERM.  What I am looking for are ways to save time and money while still providing a plan that will make this house a Passive House.  I have a very unusual idea I’ll toss out for discussion, but I also want your ideas.   This is where Passive House shines – you can model your ideas prior to building them.   We can examine the cost difference and the performance difference of different materials and methods and see just what goes into making the decisions for the final plans.  I think it will be a great experience and your involvement will make it all the more satisfying.

If you want to start now with your “what if’s” I’ll make a list.  It can be a material, method, or software modeling question.  The more you want to know the more useful this blog will be, so ask away!

Thanks!

Linda

  1. Hi Linda,

    I’m really interested in retrofits. Does this rambler sit on a crawl space? Will have to be thermally broken from the conditioned space?

    • The rambler is on a crawl space. Thermal bridges are definitely going to be an issue. Retrofits can have additional issues that they need to address because of their age as well. In addition to the Passive House requirements, I will also be discussing the lead based paint issue a house this old could have and the potential for asbestos being present.

  2. Fire up the old Stihl, sound like it’s time for a …Chainsaw Retrofit! I say fear not the vented crawl. Onward! Great project Linda. -Dan
