The Space Attributes Tool can be us

The Space Attributes Tool can be used to set attributes for one or more selected spaces in your OpenStudio model. The first four pull-down menus (Space Type, Building Story, Construction Set, and Thermal Zone) set attributes of the selected space objects. The last two pull-down menus set attributes in the thermal zone associated with the selected spaces. Most of the menus allow you to choose from a list populated by the appropriate model objects or one of the following options: No Change, Clear Field, or Make a new Object. The exception is the ideal air loads, which has a "no change" option, or yes/no. The Thermostat menu is similar to the others, but does not offer the option to create a new thermostat. You can create a new thermostat from the inspector.
