Does a Net Zero Home cost more to construct?
Yes it does, but not as much as you would think. We spend more money building a super-insulated building envelope, but we are able to see savings by using a substantially downsized HVAC system and also by taking advantage of generous state incentives. Because of this, we usually figure that there is only a 5% increase in overall cost. When figured into a 30 year mortgage, this upfront cost is minimal, and you should be able to see savings from day one!
