Lawrence Berkeley National Laboratory (LBNL) has developed a new software tool called Ctrl-flow with funding from the US Department of Energy. This tool is freely available for online use at https://ctrl-flow.lbl.gov.
The initial release of Ctrl-flow allows designers to input project information, the desired systems and their configurations. The tool will then provide an edited sequence based on ASHRAE Guideline 36-2021 that is specific to the selected options.
