Choose an energy approach before comparing wall systems.
Shawnee’s new one- or two-family permit application asks the applicant to identify an energy compliance approach, including prescriptive, ERI/HERS or simulated performance. Discuss that choice with the designer before selecting a shell and insulation package. Write down the living-space area, unfinished area and any heated shop space. Those choices help the team define the building envelope and documentation; a general promise that a package is “insulated” does not tell you what the completed residential design includes.
