[EnergyPlus_Support] Excessive Cooling Load Using Ideal Load Air System

Dear Group,
I am simulating a three storey building in Thessaloniki Greece, a region rather cold than hot, in order to estimate the anual loads for heating and cooling. The building is sufficiently insulated and has a large number of large openings to the south. Internal gains - occupants,lights and devices- and infiltration and ventilation loses have been taken into account. The simulation is implemented for constant heating setpoint at 21 C and constant cooling setpoint at 26 C. The building has no shading device. Regearding the HVAC system I used HVAC Template:Thermostat and HVAC Template Zone:Ideal load Air System with the above mentioned thermostat setpoints. In general, everything was done according to the Input/Output Manual and after consulting the idf.example files. What is amazing is the fact that the cooling loads are almost three times higher than the heating loads, something rather abnormal for the region of Thessaloniki. Is there a logical explanation regarding Ieal Load Air System and high cooling load estimation even in cold regions?I am very curious to find out what is qoing on because from what i ve read so far both in older posts in the group and in the input/output file the Ideal Load Air System works efficiently. Any suggestion?
