[Hap-users] HAP - Energy simulation

[Matthew J. Baron]

What are your inputs for the floor conditions? Does the unconditioned space have any heat generating equipment? I would check your unconditioned max and minimum temperatures to make sure they are in line with what you might expect.

Thank You,

Hi Hap Users,

I have been modelling the two identical spaces with the following options.

Option 1:          Roof - Exposed, Floor - Above conditioned space
Option 2:          Roof - Exposed, Floor - Above Unconditioned space

But I face the dramatical issue in HAP. That the point is below,



  1.  The Peak design result that is total coil load from the HAP Option 2 is higher than the Option 1. I agreed.


  1.  But I have noticed the total coil load Hourly simulation & Monthly simulation from HAP Option 2 is lower than the Option 1 at all month except peak month (May & June). The peak month also not huge difference between the Option 2 & Option 1.

The above queries I made the assumption the HAP simulation will not considered the Option 1 Floor above A/C space design condition. I think so that is take the outdoor weather condition. In this case how to model the Floor - Above conditioned space.

I have the lot confusion to conclude the above queries. Any one please gives me the clear picture.



Thanks & Regards,
Arun shankar
