[Equest-users] eQuest - Electricity consumption for cooling in winter

[Nick Caton]

Hi Frantisek,

A few shotgun thoughts:


·         Does that space have unmet hours (see airside tab summary report after a simulation)?

·         Does the corresponding zone have a cooling thermostat schedule?  Not defining one means the zone won’t call for cooling.

·         Is the zone defined as “conditioned” and not “unconditioned” or “plenum?”

·         Are the other spaces sucking all the internal heat gains out through the partitions?

·         Is there exterior exposure (envelope) incident on the space doing the same?

This all assumes you’ve actually defined your computer server room as a distinct zone… If you only defined a percentage activity allocation for the server area within a larger zone (in wizards), your model likely isn’t detailed enough to capture a simultaneous call for heating and cooling between the different zones/systems.

If none of this helps, you might consider uploading your files to the mailing list to allow others to take a look.  I suggest doing a File --> Save As… into a new directory, then attaching the few files resulting.  Also be mindful to specify which version of eQuest you’re using.

Best of luck!

Subject: [Equest-users] eQuest - Electricity consumption for cooling in winter

Hello,

I have a question about eQuest modeling - I created a model of quite simple rectangle Office building, but in results I have no consumption of electricity for cooling during winter (november - march) although in area specification I have 6 % of floor area specified as a Computer server room (data centre) with 100 % plug load in occupied and unoccupied times.

The building is in Prague (Czech republic) and from my experiences based on real dates from existing building there´s always consumption of cooling energy for data server rooms in winter in this location.

Do you know,  where the problem can? What parameter could I insert wrongly?

Thanks for advices.
