Hey everyone,
I am doing a high raise office building (14 levels, about 800,000 sf) energy model use eQuest, VAV system, chillers and boilers, core and shell, Ashrae system 7. When I run the result, unmet hour is high, 36 for cooling (Thats OK), 414 for heating.
I tried to increase air flow - Minimum flow ratio from 0.3 to 0.5 or higher, no working. Tried increase air-flow - design flow from 0.5 cfm/sf to 0.6 or higher, no working. Tried turn on night fan (cycle on any) - no working Increased heating capacity, no working. all the zones assignment seems right.
Could any masters here help me troubleshooting with this? Really really appreciate!!!! Please let me know if you need any other information~~~
