Instructions: This single-family project will use the requirements of the Prescriptive path below and
incorporate the minimum values listed. Based.on th.e size of the structure, the appropriate number of
additional credits are checked as chosen by the permit applicant.
Provide all information from the following tables as building permit drawings: Table R402.1- Insulation and
Fenestration Requirements by Component, Table R406.2 - Fuel Normalization Credits and 406.3 - Energy Credits.
