I can’t understand how it is possible without any heat from Plants having temperature inside the zone 19-21C, when outside is +26C.
The only one idea comes into mind � itts heat transfer to the ground but in this case why there is so big difference for different zones.

Dear colleagues,
I cant find an error why main part of premises are underheated and from other side, nevertheless there Sizing:System-
Sensible, !- Type of Load to Size On
autosize, !- Design Outdoor Air Flow Rate {m3/s}
0.2, !- Minimum System Air Flow Ratio
AND
AirTerminal:SingleDuct:Uncontrolled
The main part such systems work at 100% of fresh air always. The internal loads are quite big (~60W/m2), it is shopping center.
The model was made from Template:Unitary system and just a bit justified, but it runs completely strange.
Thank you very much
