States That Can Use REScheck to Show Compliance

Duncan Architect uses the REScheck energy analysis software tool to create energy code compliance reports for residential buildings—defined as one- and two-family dwellings and multiple dwellings three stories or less. All other buildings are defined as commercial buildings and use COMcheck. Most states—as shown on the map above—accept REScheck to show compliance. REScheck is a simplified energy modeling tool that is intended for demonstrating code compliance, not predicting actual energy use or optimizing complex projects. We use more powerful tools such as PHPP and eQuest to go beyond simple compliance.
