In the process of building an ICF home in Sun Prairie, and looking at getting references for a level headed HVAC profession who is willing to undertake the heating and cooling part. We have EnergyWise do our energy estimates and draw the HVAC plan. For the contractor, this would mean less turn around time for estimates. So far the contractors I talked with are high balling, and I got to hear hilarious explanation why the EnergyWise design will fail and they have better design acumen.
