We have a project that we are modeling as purchased chilled water and steam because it is on a campus that includes a central plant. The campus sells the utilities to the department. For the enhanced refrigerant management prereq (EAp3) it states that you need to do an analysis of the campus central plant and either develop a 5 year plan for replacement or complete an economic analysis showing that it isn't feasible to replace the equipment.
If we are purchasing the chilled water from the campus, do we need to go through the economic analysis?

Hi Nena,
Have you taken a look at the District Energy Guidance on this credit? If not, you can find that document here: http://www.usgbc.org/sites/default/files/DES%20Guidance.pdf
From your question about the economic analysis requirement, I'm guessing that the campus equipment does contain CFCs, and if that's the case you will need to develop a 5-year plan or economic analysis, as well as reducing the annual leakage rate to 5% or less.
