For a school, the biggest push back we have is from design engineers that don’t want to give up the fact that they don’t know how to design it. Remember to design a school system that was built 50 years is the same school we will be building now. So I can go in as a design engineer push a button on a cat system and get 100 percent design if I don’t know how to do Geothermal system I have to learn it so that takes away my upfront profit immediately. Now we’re having clients or school districts saying no I want that so figure out a way to do it.
