temperature change: Unrealistic?

I dont know what is happening with my data, but it seems almost as though the temperature changes too quick in my simulations. for exmaple, it takes less than 15 minutes for the building indoor temperature to increase from 17 degrees to 21.5 degrees. I dont think thats quite possible. the building in total is 288m2 i believe so not too small.

here is a sample of the output.csv, any ideas on how to get more realistic gradual temperature increases? how do i make data not so perfect because this is almost unrealistically good for an HVAC system...

Can you provide more detail on how you are modeling the HVAC system, specifically are you using ideal air loads

It also appears that the heating setpoint for the "office" zone has a setback of 17C until 7 AM, when it increases to 22C. The heating HVAC components seem to be sized correctly to meet that quick change in heating setpoint, since it's able to achieve that in 15 minutes.
