[Equest-users] Radiant Heating and Cooling?

[Pasha Korber-Gonzalez]

Hi Julie,


   1. You can "represent" radiant ht & clg in eQuest, by modifying a system
   to *act* like a radiant system, however be mindful that because DOE2
   can't do this explicitly there will be some discrepancies from real life,
   but it still can be a fairly realistic representation and measurment of the
   system performance.  To do this you will want to choose a Fan Coil system
   for your HVAC type and turn down your fan power in the FC units to zero.
   You will also want to probably use a DOAS & Dummy Zone approach for your
   ventilation systems.  This is an approach to use in eQuest.   I can send you
   an example file of a Dummy zone for you to look through and learn from.  You
   will also want to read about the FC system in another DOE2 document I will
   also send you (off list).  Once you understand how DOE2 represent a Fan Coil
   system, then you will understand how you can change it to better act like a
   radiant system.   Others might consider using the PIU system in eQuest, but
   I have found by my experience that PIU's are better for representing Active
   Chilled Beam systems, and Fan Coils are better to represent radiant only
   systems.  I'm happy to share more of my sim experience with radiant systems,
   but I'm also curious to hear other's simulators experiences
   with representing radiant systems in eQuest too.
   2. When you say "louvers" I'm assuming you are referencing external
   shading devices.  Yes you can input vertical exterior shades on the outside
   of your building by using the Building Shade inputs.  This can only be done
   in DDedit mode, and the inputs are based on your XYZ coordinates of the
   building space. I will send you a 3rd document (Modeling Procedures Quck Ref
   Guide) and you can learn how to input these shades in Chapter 8 of the
   document.

Feel free to write back to the list or to me if you have more questions.
You will find lots of great simulators who are always more than willing to
share thier experiences with new users.

Hope this helps,
Pasha
