Greg La Vardera replied to James McGarvey's discussion Energy Efficient Design for the not so rich in the group Energy Efficient Design"Well it looks great - must be so satisfying as well. Hope to do the same some day. Keep us posted as you settle in and go through a few seasons!"
James McGarvey replied to James McGarvey's discussion Energy Efficient Design for the not so rich in the group Energy Efficient Design"You probably are correct Greg, but one advantage of the pole construction for me was since the process took so long building by myself for the most part I was able to put roof on first and therefore not get my wall assembles and sub floor…"
Greg La Vardera replied to James McGarvey's discussion Energy Efficient Design for the not so rich in the group Energy Efficient Design"I understand what you are saying - your poles are inboard of the exterior walls, so yes, you don't have temperature gradient across the diameter of the pole, but no, you have a gradient over the length of the pole which at the exterior…"

James McGarvey replied to James McGarvey's discussion Energy Efficient Design for the not so rich in the group Energy Efficient Design"Greg, if I had built platform construction on top of the poles then would have had headers over doors and windows, thus more lumber in walls, With the wall system I ended up with about 10 inches of wood at the poles, built my inside wall to edge of…"
Greg La Vardera replied to James McGarvey's discussion Energy Efficient Design for the not so rich in the group Energy Efficient Design"Pole foundations are affordable, but I have to wonder if you would have been better off stopping them at the floor. We put so much effort into isolating the thermal bridges created from studs, and here you have these large diameter poles passing…"
Matthew Redmond replied to James McGarvey's discussion Energy Efficient Design for the not so rich in the group Energy Efficient Design"Hi James, Great house !!! Four years ago I built a similar pole house for customers up here in Brookfield,NY. The big difference was it was built on grade with a super insulated slab. Walls were 8 inches thick and foamed with a thermal…"

Energy Efficient Design for the not so rich
Having worked for 30 plus years in the Weatherization program I was not rich. When we had the opportunity 3 years ago to build a new home for my wife and I we tried to take our Building Science knowledge and build a home close to zero fossil fuel heat. Thought I would share with the group how we have almost achieved this for under $40,000 by building a pole constructed house. http://cheoyleeassociation.com/family/NCHouse.html …See More

James McGarvey replied to Linda Wigington's discussion Low Energy Home Storytelling - Insight & Inspiration for 1000 Home Challenge Projects in the group 1000 Home Challenge"Linda, we have not talked in a long time. Anyway I have just about completed our new home using my years of learning. We may come close to hitting the Passavhaus standard. Will soon be posting a complete rundown on how it was done.…"
