Hi Christopher, hi everybody,

I've juste seen the two first posts on this page but it does not help.

We are purchasing heat from a district heating plant (100% green). The USGBC's DES technical guidance is a bit confusing.

- District Energy System (DES) is defined as a central energy conversion plant and transmission and distribution system that provides thermal energy to a group of buildings (e.g., campus). Does this definition apply for one building connected to a district heating regional plant?

- Rf. EA c1. Option 1: Energy simulation. We are targeting to obtain a maximum of points. Is it correct we have to run 2 energy simulations (Building stand-alone scenario + virtual DES-equivalent plant scenario)?

- Is there any beneficial effect to use the virtual DES-equivalent plant scenario? Is there any beneficial effect to be connected to a 100% green district heating system?

Thanks in advance for your comments!

Kind regards,
