Balanced mechanical ventilation is code required in all new construction in my home state of Minnesota. Indoor air quality has become a big topic with today’s pandemic. My market uses HRV’s or heat recovery ventilators almost exclusively. They work great at supplying the home with filtered fresh air and at controlling indoor humidity levels. You can read more about HRV’s here. Continue reading “Construction Design-HRV or ERV”
Construction Design-Code Minimum House-Mechanicals
At the time of this writing, construction on the code minimum house is coming to an end. This has been a fun and rewarding project for me because not only was I able to design much of the home, I was also directly involved in the construction. Continue reading “Construction Design-Code Minimum House-Mechanicals”
Construction Design-Randy’s Dream Design
Guess what? I just won the lottery! (Not really, but for the purpose of this blog, let’s pretend.) I’m looking to build myself a new home. I have choices. I could build a McMansion with plenty of space I don’t need and will never use. I could concentrate only on the interior finishes and how the house looks. If you’ve ever read my blog, you already know what direction I’ll take. The house won’t be big, a couple thousand square feet is plenty for me, maybe a rambler with a second story over part of it built on a slab, no basement or crawlspace. Being a BS* guy, I would make an invest in the stuff that is hidden, those pesky control layers I often talk about. It would be based on the Pretty Good House concept.

Construction Design-The Code-Minimum House-An Introduction
I am currently involved in a new home build working with my friend and general contractor, Strommer Home Improvements. My involvement in the build is that of the designer, tester, and laborer. Yep, I’m back swinging a hammer Continue reading “Construction Design-The Code-Minimum House-An Introduction”
Energy Audit-Ventilation Recommendations
I’ve been asked this question a few times. “At what point do I need to add mechanical ventilation to my home?” The answer, it depends. Continue reading “Energy Audit-Ventilation Recommendations”
Construction Design-Concreteless Slab on Grade-Mechanical Systems.
The concreteless slab on grade home had a lot of unique building materials and techniques, at least for my area of Northern Minnesota. The mechanicals of the home were no different. Continue reading “Construction Design-Concreteless Slab on Grade-Mechanical Systems.”
Mechanicals-Adding Mechanical Ventilation to an Old Home
Something I suggest before any renovation to an older home that includes improvements or changes to the water, air, vapor, or thermal control layer is to have a blower door test conducted. Continue reading “Mechanicals-Adding Mechanical Ventilation to an Old Home”
Codes-Crystal Ball
The way we build a home is constantly changing. New codes come out every three years, new technology is evolving faster than I can keep up, and new materials help to make building a home easier. (Sometimes!) So, what are we striving for? Continue reading “Codes-Crystal Ball”
Building Science-Air Changes
My last posting I talked about air changes at 50 Pascals (ACH50) and air changes natural (ACHnat). This week I’m going to discuss how much fresh air a home needs in a northern climate and a couple of the codes Minnesota has in force that work well. One of these codes, the requirement for balanced ventilation, helps add durability to our structures. Continue reading “Building Science-Air Changes”
Construction Design-Humidity Control in a Garage
I watched an electrician install two ceiling fans in an attached garage recently while I was working as a subcontractor on a new home being built. I quizzed him on their use and he said moisture control. This got me thinking about controlling humidity in a heated garage in a northern climate, this week’s topic.
