Berg: Dealing with utility companies for submetering is always a challenge. Some utilities allow submetering of all residential units while other utilities require utility meters for each residential unit. This greatly impacts spatial requirements and billing methodology. These conversations need to occur and be documented with the utility at the very beginning of the project.

CSE: Describe a recent standby, emergency, or backup power system you designed, and its challenges and solutions.

Berg: An owner recently had us locate an emergency generator on a median in the middle of the street underneath an elevated train track. Coordination needed to occur between the utility engineers, the city engineers, and the train engineers (pun intended) to allow this to happen and to navigate the infrastructure from the generator, across a city street, and to the building.
