<div>Adding to the radiant system discussion, consider modeling seconary loops which are then attached to the fan coil units. This will help define radiant system flow parameters independent of your primary loops and also since you have turned down the supply fan, the supply temperatures inputs you would typically used in an air only system would not apply.</div>

<div>Hi Julie,</div>
<div> </div>
<ol>
<li>You can "represent" radiant ht & clg in eQuest, by modifying a system to <u>act</u> 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.</li>
<li>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.</li>
</ol>
<div>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.</div>

<div>Hope this helps,</div>

<div>Hello everyone, this is Julie Shin.<br> <br>1. I am curious whether it is possible to add "radiant heating and cooling" for eQUEST simulations or not.<br>If it is possible, could anyone please let me know how to do so?<br>
<br>2. Is it also possible to add vertical louvers? I have tried adding horizontal louvers, but not the vertical ones.<br> <br>Thank you everyone and have a nice day.<br> <br>Julie Shin.<br> <br> <br></div><br>_______________________________________________<br>
