More AIA IgCC guidance is on the way for commissioning and energy modeling. To date, only Maryland has adopted the model code, which was released in late March. However, Maryland is making compliance voluntary, not mandatory. In New Jersey, there is already opposition to its adoption among government entities.

Apparently, there is also some opposition to the model code among architects. At a convention session on the guide, almost all of the 100 or so attendees indicated, by a show of hands, that they are concerned about the impact of a mandatory IgCC on practice.
