As practitioners who design and build homes to the PHIUS standard know what, in terms of efficiency, they want the typical home to be like. However, what is the typical home like at this moment? We have gathered data from RESNET on over 5,000 homes that were given HERS ratings across the state of Illinois. The data from the ratings were disaggregated to show the distribution of insulation R-values,, blower door results and mechanical equipment efficiencies. How do these homes stack up against the code? Against a PHIUS home? The aim of this presentation is to begin the process of charting a path from where we are to where we want to go (all homes meeting the PHIUS standard…think big!).
