You are correct in stating that the labor for our local Habitat for Humanity houses is donated by our volunteers, so there is no monetary labor savings on our Habitat houses when using SIP's. I should have stated that in a for-profit house project the labor savings from using SIP's would have been more than the initial additional cost of the SIP's.
There was a labor saving component since our volunteer laborers worked on other phases of the construction process instead of on stuffing batt insulation into the cavities of a stick-built frame.
We have also found that the energy savings of the SIP's house will pay for the additional expense of the panels.
As stated previously, using SIP's is an experiment in progress.
