[Bldg-sim] EE4 heating source

Hi  Alex,

 

Define your system as a 2 pipes fan coil (or 4 pipe if you also do zone
cooling ). The heating at the zone level will be handled by the hot water
coming from your plant boiler.  Define your plant boiler energy source as
electric.  The energy consumption for your zone heating coil should then be
electric for the proposed and reference building.

 

You can also look in the EE4 modelling guide for 2 or 4 pipes systems
operation.

 

Don’t hesitate if you have more questions.

 

Regards,

I am using EE4 to model an office building with natural gas RTU’s but
electric reheats at the zone level.   The reference building is only using
natural gas for heating, rather than gas + electricity as in the proposed
design.  I’m getting very nice energy savings overall, but since my
electricity use for the proposed case is actually higher than that of the
reference, the cost has not gone down much at all  (electricity is a lot
more expensive here than natural gas.)

 

Is there any way to get EE4 to model the electric zone reheat capacity in
its reference case? 

 

I have the RTU’s defined with electric zone reheat coils.  

 

Thanks!

P.S. I’m new to the list, so hi!  Nice to meet you all.
