Diligence is key in building a Passive House.\u00a0 Making sure all the details are incorporated as planned is necessary.\u00a0 When Dan’s windows showed up with the wrong stickers on them there was more than enough heartburn to go around.\u00a0 Windows are a very important part of the Passive House configuration.\u00a0 Figuring out where they are located, how much sun they let in (or keep out), how large they are, what their physical properties are in terms of materials & construction are all very important.<\/p>\n

As the truck pulled up Dan noticed immediately that there was a problem.\u00a0 A call to the manufacturer determined that it was most likely a sticker mixup, but just to be sure Dan did not install them until the engineer determined that they were in fact the right windows.\u00a0 Phew!\u00a0 I am happy to report that they are in and I have the pictures to prove it.\u00a0 Dan’s friend Dale even came up from Portland to help put them in.\u00a0 Additionally there is now a set of stairs to the 2nd floor and I was able to go inside for the first time and I took more pictures.<\/p>\n

If you notice, the windows are not flush mounted to the outside as you would expect.\u00a0\u00a0 There is a reason for this.\u00a0 The windows perform better thermally if they are placed closer to the center of the window well.\u00a0 There is a program available from the Lawrence Berkely National Laboratory called THERM<\/a> that can be used to test for the thermal capabilities of construction materials, primarily windows and after testing the position and types of materials, it was found that where the windows are located within the assembly is an important factor.<\/p>\n

With the windows in, the Tyvek and siding going up outside, we are getting close to another Passive House feature – the airtight layer.\u00a0 Dan designed his Passive House to have the airtight layer on the inside of the structure.\u00a0 He will be using OSB over the larsen trusses on the inside, sealed, and then will blow in dense pack fiberglass insulation into the cavity.\u00a0 Once the doors are in and any other openings are covered it will be time for the blower door test.\u00a0\u00a0 If you want to be sure you don’t miss any updates, you can register for email notification on the right hand side of the page.<\/p>\n
