Baseline heating source where no fossil fuel is provided to building

Marcus,thank you for the prompt response.Kevin

Marcus,I now have a better understanding of where I stand with regards to the 90.1-2010 and 90.1-2016 standards and LEED energy modeling. I have a situation that I am hoping to get a resolution on.We are completing an energy model for a post March 2024 registered LEED BDC New Construction v4.0 project. We created an energy model in a ASHRAE 90.1-2016 compliant software program. We belatedly realized that we should have selected a ASHRAE 90.1-2010 compliant software program.Are we allowed to use the ASHRAE 90.1-2016 energy model and output to provide reporting for energy and greenhouse gas under the ASHRAE 90.1-2010 approach using the v4_Minimum_Energy_Performance_Calculator-v07 (2024 update).xlsm spreadsheet? Natural gas is not available to the building. The ASHRAE 90.1-2016 provides guidance to use propane instead for the baseline heating system. I assume that we should follow this rule in reporting the baseline energy usage?Thank you.Kevin

Thank you. I have evaluated the results of our 90.1-2016 energy model in the 4.1 MEPC with propane as the baseline for buildings with no natural gas per 90.1-2016 rules and I am finding that the 90.1-2016 energy model does very poorly. That is why I was planning to evaluate it under the v4.0 MEPC instead.

We have some software that has a limited access to ASHRAE baselines and it is not easy to switch between them.Though thank you for reminding me to look at ASHRAE 90.1-2013. We have a version of the energy model in the software with an ASHRAE 90.1-2013 baseline. I confirmed that footnote 2 under table G3.1.1-4 does allow the baseline to be electric when the proposed heating is electric based.
