Hello, I have taken a look at Appendix B which includes Title-24 guidance within the District Thermal Energy LEED Guidance document. However, we had received the following reviewer comment and I just wanted to make sure that it's outdated. It seems to say that you cannot take credit for DES when using Title-24. Maybe I just need help in understanding: can you take credit for DES when using Title-24?
"The project team has stated that they have followed the document Required Treatment of District Thermal Energy in LEED-NC version 2.2 and LEED for Schools, version 1.0; (DES v1) dated May 28, 2008. In accordance with USGBC guidance, this approach should not be used with Title-24 modeling.; Projects with district energy plants that are documented using Title-24 2005 in lieu of ASHRAE 90.1-2007 are NOT required to follow the energy modeling guidance provided in the document "Treatment of District or Campus Thermal Energy in LEED V2 and LEED 2009 Design and Construction"; (DES v2) dated August 10, 2010 which can be accessed at: http://www.usgbc.org/ShowFile.aspx?DocumentID=7671.
However, Title-24 2005 does not allow credit for the efficiency of district energy systems. Therefore, if the project is taking credit for the efficiency of the district energy systems serving the project, then the DES v2 document referenced above must be followed in its entirety.
Please revise the model to follow the Option 2 requirements defined in the DES v2 document. Otherwise, confirm that the Proposed case plant inputs represent the default Title-24 inputs, and no central plant has been modeled for the Proposed case in the Energy Pro software. Update the form and Table 1.4.1 through 1.4.6. Attach Title-24 compliance forms (PERF-1, ECON-1, UTIL-1 and OLTG) as well as BEPS, BEPU and ES-D reports for the Baseline and Proposed cases to confirm correct modeling and reporting."
