Showing Compliance for Additions & Alterations Using REScheck & COMcheck

This webinar provided an understanding of how to show compliance using COMcheck and REScheck for alterations and additions to existing conditioned buildings.  Alteration projects involve changes to or replacement of existing building components that are part of the building thermal envelope, interior and exterior lighting, heating, ventilation, air conditioning, water heating and other equipment.  Addition projects involve adding new conditioned floor area to an existing conditioned building and are treated as new construction.  This event provided instructions for how to determine compliance for these types of construction projects as part of DOE’s Building Energy Codes Program Energy Codes Commentator webinar series.
