[Equest-users] eQuest Generated EFLH

What is the EFLH for lighting controlled by photo sensors? Fans that have VSDs? Etc.? To get accurate EFLH you would need hourly reports.

LEED has some really goofy reporting requirements.

John & all;

That could work for the plant equipment, but LEEDv4 is requesting EFLH for all annual schedules. We have a project that has 4 different main occupancy times/groups. Which cascades out to occupancy, lighting, fans, etc. Many, many schedules.

I received a separate suggestion to check under File>Export, but none of the 3 options there had anything like the EFLH.

LEED has a ‘calculator’ in their documentation, but its built arround different days/week (which also don’t align in this project). Something could be built in excel to handle this – but I saw little need to recreate the wheel if eQuest/DOE2 does this automatically.

My best guess (assuming you want cooling for example) is to make a single chiller for your building (gotta be PLANT equipment). Figure out the peak cooling load from SS-D and size the chiller accordingly. Run the building. Look in PS-C, with 10% increments of load.

Multiply each 10% load increment (say chiller is 1000 ton, so 100 tons for 10%, 200 tons for 20%, etc) by the number of hours shown for that increment. Take the total ton-hrs and divide by the 1000 ton (for this example).

That should give you equivalent load hours.

Does anyone know if there is a report or means from eQuest to generate the EFLH (equivalent full load hours) for each schedule?

Colleague of mine believes VistualDOE was able to complete and hoping there is a comparable tool/report.



Thanks in advance.
