Hi Zhongming,
We have a question regarding CEA functionality to incorporate multiple energy sources to a single building. As far as self-exploration goes, we concluded early on that CEA through its archetypal method does not really allow multiple energy carriers in its HVAC_Supply definition.
Our initial enquiry into this functionally stems from the possibility of an existing building having PV already installed.
We could assume that the building's electricity is supplied by PV by adding a supply_assemblies that mimics PV. But, rarely is the case that PV installation can reach autarky.
We saw CEA as a tool that assess a building current singular energy source, and then explore the PV potential as a simulation rather than definition functionality. Is that so?
We raise this question again since we are moving forward with operational LCA, which may be affected by this early definition issue.
Thanks!
Bernad and Gustavo
