What is the best insulation for a small Zero Net Energy home?
At the moment I'm designing a small house that I hope to be able to be able to live in all year round, with zero bills so I'm using wind, hydro and solar for electricity and rain/lake water for water. I want the house to be as well insulated as possible so I have to generate less electricity, so I'm wondering what sort of insulation to use and what thickness (it doesnt get too cold where I am, almost never below 0F). Theres so much different advice out there for this... I'd also be very interested in any other cheaper/eco friendly material ideas I could use because I want to build this mostly diy on a small budget.
