The big remaining items are: Installation PSI values for our windows - results for this will be in a separate blog post.  Zehnder Commissioning to verify airflow in each room and ensure proper balancing from the supply and exhaust from the unit Official Blower Door Test So this post will go into some depth on what is required for the Passive House Institute Airtight Test Calculate the House Air Volume This is maybe the biggest difference between the ASTM and European Standard. We calculate the air volume of the house from slab to interior drywall and exclude ALL interior wall and floor air volumes. Essentially the "visible air volume" inside the house. Sketchup makes this much easier! I broke up the volume into 4 components Volume of the Basement = 8,888 cuft  Volume of the 1st...

Questions for my wife

Questions for my wife Many times during tours questions come up that are best answered my by wife. The questions are generally asking for a different perspective from mine. It makes sense. I am, after all, selling Passive House Design and Tradesman services through Airtight Services. So how much can you believe from a salesman?  My wife Brianna has offered to answer some questions from our most recent open house. Here you go! These questions are in no particular order. Hi Everyone! Brianna here. Before I go into answering these questions just know that I am not a designer, architect or engineer. Many of the finishes in our house I found on pintrest. Some of these questions are hard to answer, but I will do my best. What was the biggest challenge with the layout / floor plan in order to keep it "Passive"? Definitely working within the "simple shape" I am really not good at visualizing how large a space will be from the prints, so we ended up with bedrooms on the 2nd ...

Video's

Video Compilation  I have compiled a list of video's I shot during the construction of Rochester Passive House. All of the Video's can be found by searching "Rochester Passive House" in Youtube Enjoy! One of the 1st Video's I took was during the window delivery. They are heavy! We unloaded the container with a skid stear and had to push them into an on site storage container. This group of 3 video's shows what we needed to do to raise the outer wall of our double wall assembly when the inner wall was already built This video shows the setup and plumbing of our drain water heat exchanger. This video shows the installation techniques of damp spray cellulose. This wall is an interior wall for sound deadening, but you can see the installation from both sides of the wall. This video shows the technique we used to complete the insulation of our attic when we cannot see the levels of insulation. We need to maintain at least 24" of blown cellulose in the attic.  ...

The Passive House Experience - Experienced / Water Heater Install

We've Moved In! So, where do I begin. It has been so long since I posted anything... What have I learned from living in a (soon to be certified) Passive House? It is QUIET! We don't live in a noisy area, but when you close the door you can actually FEEL the quiet.  When something is sound proof, it keeps the outside sounds OUT, but also keeps the inside sounds IN. My 6 year old takes piano lesson. the piano is LOUD! The ventilation system works great! Smells don't linger at all. My biggest "complaint" with it is when the boost button it hit, you have NO indication it is running any faster. There is no light or sound to suggest it is on high - you just have to believe it.  We have had as many as 15 people in the house on a hot sunny day and didn't over heat the house. The box elder beetles are BAD this year. We don't have any in the the house - no air leaks means bug proof as well. We do get some fruit flies but I think they come in with our fruit Horse fly...
