New House Build in the Country!!!

[Billrog]

You certainly lucked out on finding a very good crew I was building most of my life & still wouldn't hesitate to have them build me a home.
As for sealing home to extent we do today it so you can size and properly control the air exchange in the home with minimum heat loss. I realize spray foam is a good insulator for sealing but fiberglass with 6 mil poly taped and acoustic sealer bottom plate and where vertical framing members meet eg. studs and cripples you'll have a well insulated home. It would be difficult justifying the extra cost of spray foams pay back $15,000 is a lot of money and take many years.

I'd really like to learn more regarding this. Outside of energy waste, I don't see the advantage of foam knowing it would take years to recover the cost. Factor that with solar becoming more affordable and it seems like a no brainier to do your best with yesterday's materials partnered with today's practices?

I checked on YouTube and found nothing but perhaps my search terms were incorrect.

I don't know if you are thinking like me, But if you designed the roof for solar panels, wouldn't they act as super premium radiant barriers in the summer, while they provide shade and electricity??? 15K would be a great start to a solar system.

And I'm not even a tree hugger. I guess I just look at it as which way you would spend your 15K if you had it...

Wakey this should answer a few guest ions for you.

Kyle, I'm with you and Billrog, THANK YOU!!

I'll chime in on why we did foam. It made sense for us but may not for everyone. Our main reason was energy waste. On a smaller home the savings may not be there however we have about 3900 sq/ft of conditioned space 1st and 2nd floor and another 900 in the basement that is heated occasionally. On top of that the house is mostly open to the roof line with very little attic space. Here's a pic of the great room to give you an idea.


I figure my cost to have someone batt and blow insulation would have been about $6000. Closed cell spray foam for the entire home, 3-1/2" in walls, 5-1/2" in roof, and 2" on basement walls was $22,500. Extra expense for foam = $16,500. I'm 38 years old and hope to live in the house for another 30-40 years if I'm lucky. Now let's look at some numbers. If I figure a 15 year payback I would have to save $1,100 per year in heating/cooling. Based on my usage I figure I'm probably saving more than that and am closer to a 9-10 yr payback. Anything after that is savings each and every month. For this winter heating season from Nov 1st to Feb 29th I it cost me $590 to heat our home for the season using a geothermal heat pump. I know others who have similar sized homes with batt insulation and are paying $400 per month for heat with equally high bills in the peak cooling season. On days when the temps reach 50 degrees and sunny we can turn the heat off until sundown. We could have also made up some of the extra expense with a smaller sized HVAC system if our contractor had sized ours correctly but that's a whole different story.

A few other things that come to mind. Extremely quite house. Even temperature throughout. Very low airflow needed to heat and cool equals an HVAC system that you never hear or know when its on or off. In regards to solar we looked at it and looked again last year. Unless you can get some very good subsidies in addition to the federal tax credit and DIY the system install the payback is still not there.

JK, beautiful home! If I had the money for foam and Geo I'd do it but with my budget I might get solar for an offset. 15 years from now when I would reach zero with foam, solar will be even more efficient and I could upgrade.

I like the lack of waste and quiet but we all have different check books.

JK's house is a work of art. If you haven't seen it, check out his build tread.

I understand Wakey. Every build is a trade off between wants, needs, and budget. My reason for posting was in reply to your question about why anyone would spend so much extra for foam. For us the it made sense as I felt the payback was there and in a reasonable time period. When we built our previous house 15 years ago there's no way we could have sprung for extras such as foam or geo even if it paid in the long run. We had a metal building for the business we were starting and built the house inside the building on an upper level. I promised my wife at the time we would build a regular home in the future when our checkbook was in better shape.

Justin the house is looking great. I'm late to this thread so I'm sorry if it's already been mentioned but after your mechanicals have gone in and before sheetrock use a good quality camera, high megapixal so you can get pictures of full walls and still zoom in for smaller details. Move room to room taking pictures of everything. Walls, ceilings, plumbing, wiriring, hvac ducts, etc. I've already gone back to my pics a couple of times and is really nice to be able to pull up a wall section if needed and see exactly where something is at.

I can certainly agree with your numbers. There are many reasons that closed cell is the best. I have lived in a house with a quiet HVAC system, and I miss it, but I am used to what we have now.

My question is more aimed at those of us who live in the deep south with months of 100F temps some years, as opposed to having to fight off the winter chill for many months. So with having to run the AC 6-9 months of the year, I was just wondering if the solar panels and the radiant barrier shade they provide would be better down here.
