Revision history [back]

Here is a LEED Interpretation ruling on a similar situation (shared condenser loop and equipment). The relevant section of the ruling states:

It appears, based on the description, that the building does not fall under the District Energy requirements, in that it is not provided with cooling or heating from a district source, but rather provided with condenser water which feeds heat pumps that produce the cooling and heating within the building. As such it is not required to follow the methodology defined in the "Required Treatment of District Thermal Energy in LEED-NC version 2.2 and LEED for Schools."

You should make sure the ruling is applicable to your rating system version, and possibly do additional searches for other interpretations that may have been made on this issue. This one doesn't make any determination on how the equipment should be modeled, but given that the district guidance doesn't apply, I would probably include the equipment in both models.
