Hello Marcus, Projects pursuing CS certification are allowed to prorate the model based on owner control. Why would they not have a similar path for manufacturing facilities pursuing NC certification? For example, the "widget maker" consumes 70% of the building's total energy hence the modeler would be able to prorate the model as if 70% were outside the control of the owner. thank you for any insight you can provide.

CS projects are split between the owner and tenant. It is the fundamental issue of control that makes the difference. If the widget maker builds a building then they control all of the energy use including the process loads and can make decisions that will reduce energy use of that process. The owner control method for CS was a compromise which was allowed to enable CS projects to ramp up their energy savings over time. In v4 this adjustment went away.
