Hi, I transfer the discussion to the Equest mailing list as asked.

I know that my zoning is not usual but I had to do this because I have exterior floor and I only find this solution.

I will check my interior wall types.

I know that I have a heat recovery loop on my chiller. I try to delete it to see the influence that it has on the energy consumption but as it has to be, the influence is not so important.

Please check your zoning. Unless the model did not load correctly on my machine, I am getting a variety
of small intersecting zones on levels 2 & 3. And check interior wall types (std vs air vs adiabatic).
Also, looks like you are using a heat recovery loop on your chiller. Maybe that helps?
