I am using Energy Plus software with Sketchup-Open Studio plug-in. I have modeled G+2 Floor residential building .In my model i have used PTHP system. I was getting zone cooling energy in the month of JUNE - (Ground Floor Zone - 444.76 KWh , First Floor - 634.67 KWh , Second Floor - 1004.35 KWh, and other months also result variation comes like june month.

here comparing to ground floor , first floor increase 1.4 times more and second floor 2.3 times more. obviously, comparing to ground floor other floors energy will increase. But here i am getting more energy consumption for my model. please suggest to move correct direction for my earlier research. Thank you.

It isn't clear specifically what your question is? Do the other months look too much like June than you expected? Do you just think consumption is too high globally? Or is it something else?

Actually sir i was getting energy consumption value too higher than the ground floor.

But the ground has no roof exposure, and may be getting free cooling from the slab, depending on climate zone and ground modeling, so it isn't a surprise to see it with lower cooling load that middle or top floor.

Sir, Even though first floor has more load, Is it possible this much value.
