for all Audit Templates except New York City Energy Efficiency Reports, audit report buildings may be duplicated by selecting the 'gear' icon in the Options column next to the building you wish to duplicate, and then selecting 'Duplicate Building' from the resulting drop down menu. The newly created duplicated building will be loaded in edit mode.  Note that the building name of the new building will be identified as '(duplicate)' and the Building Information screen will include a link to the original report building.

Individual New York City Energy Efficiency Report buildings may be duplicated by selecting the blue 'BBL' button while editing and then selecting the 'Building Information Numbers link from the BBL Property screen.  From there, select the 'gear' icon in the Options column next to the building you wish to duplicate, and then selecting the 'Duplicate Building' from the resulting drop down menu. The duplicated building will then be available as part of the same BBL Property.  

Properties and multiple buildings associated with the same property may be duplicated at once by navigating to the NYC Properties screen, selecting the 'gear' icon in the Options column next to the property you wish to duplicate, and then selecting 'Duplicate Property' from the resulting drop down menu.
