I would greatly appreciate any answers and comments on formulating a submission and/or CIR.
I am working on a LEED project which is heated by steam from a coal fired plant and is subject to the USGBC's District Thermal Energy document https://www.usgbc.org/ShowFile.aspx?DocumentID=4176.
Should the baseline hot water boiler plant in the Step 2 analysis be:
A) a coal fired boiler with the proposed boiler efficiency since 90.1 does not address coal fired boilers,
B) a natural draft coal fired hot water boiler with an assumed code efficiency since 90.1 does not address coal fired boilers,
C) a natural draft gas fired hot water boiler with the code efficiency referenced in 90.1, or
D) something else?
Remember the metric is energy cost savings.
If you reread it, replacing the word 'coal' with 'trash', does your answer change?
