[Equest-users] eQuest Generated EFLH

[Daric Adair]

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.
