Are project constraints limiting your design from meeting the ECBC’s prescriptive compliance criteria for building envelope components?
The envelope trade-off method is an alternative compliance path that enables your design to trade-off poor performance of one or more envelope components with beyond code or exceptional performance in other component/s. The Envelope trade-off calculator evaluates the user compiled construction assemblies for ECBC compliance.
Provide project information and details of envelope assemblies component by component. Click ‘Calculate’ to see envelope performance by component and overall compliance. You may also save a report by clicking on ‘Generate’.
