I would just add a direct acting heater as a room unit.

When doing an energy model, especially for LEED, zone components, where they represent a real life scenario, complicate

Eh... so this is a bit more subjective of an answer. It depends on what you are doing. I come from using eQuest origin

This could be a little different depending on which version of the VE you are in. The unmet load hours test and HVAC co

Yup, that is going to be the device output.

Add a direct acting heater to the room units. It can be added to any HVAC system's principal space (small green box).

I meant coil target LAT not CW loop temperature.

I would dive a bit deeper into the WLHP component results to understand why the coil isn't able to achieve the LAT. I s

There are lots of potential issues. Here are a few unique to that system type though. 9c is the DOAS with WLHP system,

I would first question whether you have more than 20k ft2 of non-predominant heating source spaces in order to need syst

Thanks, I've used BLCC before. I knew HAP and Trace have something built in. I didn't realize EnergyPlus did though.

Do you typically perform a LCCA or simple payback analysis? If you do LCCA, what tool do you use? Where do you get the

Done. I can provide a good contact for getting Daikin chiller performance if you are interested.

This is interesting because I have successfully gotten Daikin, Trane, and York to fill out the Taylor Chiller bid form.

The only way to get a separate energy consumption for each zone system is to create separate meters in Apache, and then

It sounds like you are really looking to confirm that you are meeting the IPLV requirement in addition to the full load
