NC-2009 EAp2: Minimum Energy Performance
EAp2- Option 2 Prescriptive Method
The current project consists of an existing building that is being renovated along with a new addition to the building. The prescriptive method indicates that 1/2" of rigid insulation is required. Is this required for the existing building? What are the requirements to update the existing building envelope to the current ASHRAE standards? The new addition will be compliant to all ASHRAE prescriptive requirements. The addition is 40% of the entire project.

This prescriptive approach is all or nothing. If you were just renovating a building that renovation would need to comply with every strategy. The ASHRAE AEDG contains prescriptive requirements above the 90.1 prescriptive levels. So you would need to implement every item on the prescriptive list in the AEDG in order to use this option.
