Hi All,

I'm building an energy model in EE4 program. I'm getting a lot of heating unmet hours (in the thousands). The majority of the zones with unmet hours are corridors where I only have make-up air (MUA unit with hot and chilled water coils) serving those spaces. The suites (that are served by 2 pipe fan coils) are in separate systems. I tried decreasing and increasing the airflow/heating capacity in the corridor system but it is not affecting the amount of unmet heating hours at all.

Anyone know why the unmet heating hours are so high?

Thanks and Regards,

Katie
