I'm trying to put an optimum start schedule on my building. I noticed that adaptiveASHRAE is the default Control Algorithm for AvailabilityManager:OptimumStart so I ran with it. However I can't get the output:variable Availability Manager Optimum Start Time Before Occupancy to change.

After doing a little research I found that between EnergyPlus versions 8.8 and 8.9 a note was removed from the Input Output Reference saying, "The AdaptiveASHRAE algorithm has not been implemented yet." Implying to me that it has been implemented.

I dug into the SystemAvailabilityManager source code to try and figure out what why my model doesn't start before occupancy, and I found what I think is the relevant selection of code:

else if (SELECT_CASE_var == AdaptiveASHRAE) {
                AvailStatus = NoAction;}

The code implies with NoAction, that it still hasn't been implemented. I looked back to EnergyPlus version 8.2 and found the code above hasn't changed. Is there somewhere else in the code that I need to be looking to try and figure out why my model doesn't start? Has adaptiveASHRAE been implemented?

This is a great report and with investigation, thank you! When you are fairly certain you discovered a bug, you should post that directly to Github issues for the development to address.

I confirmed your belief, and opened issue #7089.

So bottom line: No, it still hasn't been implemented.

Is there an update for the status of this feature? Is adaptiveASHRAE implemented?

The issue I linked is still open.

@Raul Teixeira the link to the EnergyPlus Github site that Julien shared is where new issues or feature requests for EnergyPlus are logged. The EnergyPlus development team then addresses those issues or feature requests that they and EnergyPlus users find important. This specific issue is still open, so it has not been addressed yet. You can "vote" on this issue by commenting or adding a "thumbs up" emoji to let the development team know you think it's important.
