Yes it was SIP in that building.I am surprised that you are against the cost, the building is a metal rool over partial sip construction. That is right up your alley.
It would be hard to justify the costs with a grid tied system. Though the costs do seem minimal, Sip with metal roof is already done affordably.
Certainly only a partial solution but together with other ideas I think it is a good one. Seems like there is not much info on this and I hope some innovation develops.
What I was eluding to was if it was a SIP that is not what their study shows therefore it is not a fair comparison to a fiberglass insulated ceiling in the other building
I am not against using SIPs at all, but it is a waste of money to lay SIPs in the flat and then build a secondary roof over the top, the metal roof that was built was not built to hurricane code requirements either so how can one identify what the true costs are?
I don't think the study has accomplished what it could have if the construction methods were kept similar , we really don't know if the night cooling is beneficial or not
