Hi,
i'm dealing with EFLH for interior ventilation in baseline and propose, over 8000h/year, double than another ones such us space cooling and receptacle EFLH, <4000h/year?
These figures from HAP Carrier software. if anyone has got this like me. will appreciate if you can leave any suggestion or comment.
Thanks!

Hard to say what the issue might be with so little information to go on. Check the schedules, check the nature of the fans (constant vs variable), check the loads. Don't necessarily compare this to other end uses. Check to see if the results make sense relative to the inputs for that end use.

Sorry for little information, Marcus. My project type is high rise residential building. I set occupancy schedule with EFLH 4800h/year. As you suggested, I switch into fan cycled control. The result shows the Fan - interior ventilation EFLH reduction by 25%, 6200h/year, which significantly differs from my schedule.
i will find out more reasons to fix it. anyway, if you have any ideas, tell me, Marcus.
Thanks!

Do some of the fans bring in outside air as well as space conditioning? I description of the HVAC system would help.
