[Bldg-sim] USGBC - District Heating & Cooling plants

[Vinay Devanathan <vinay.devanathan@xxxxxxxxx>]

Hello All,

According to the District Thermal Energy v2 document on the treatment of campus plants, the baseline systems have to altered in concert with the changes provided in Table 3 of the document.

In Table 3, System 3 of Appendix-G is revised as a 4-pipe CV AHU, if the proposed system uses district energy for both cooling and heating.

My question is - Does 4-pipe CV AHU mean a single constant volume air handler for the whole building? or would it again be single-zone systems as System 3 of Appendix-G was supposed to be?

It would be great if anyone can throw some light on this.

Thank you.

Regards,

Vinay
