What is the anticipated extra cost of implementing the stretch energy code for updating a kitchen?
If we consider a typical kitchen upgrade which will replace plumbing fixtures, remove and replace the appliances, install new cabinets and countertops, and installing a new floor, the only incremental cost for compliance with the stretch energy code will be purchasing Energy Star compliant appliances. These changes will not trigger any energy related changes to the rest of the home like a new heating system or attic insulation. If you expose existing ceiling, wall or floor cavities during the renovation both the baseline building code and the stretch energy code require that any empty cavities be filled with insulation that meets or exceeds an R value of 3.5 / inch. According to Energy Star documents the incremental cost of purchasing an Energy Star refrigerator is $30 and the incremental cost of purchasing an Energy Star dishwasher is $0. This means that the incremental cost of completing this kitchen upgrade under the stretch energy code will be $30.
