1) To design and verify parametric function of virtual air temperature for proper setup and control of thermal comfort for heating and cooling, which will include in main parameters attributes of a heating and cooling body, human customs and room environment (till 2018). 2) To integrate the function into a simple controller as precursor before output control function to improve efficient control of various advanced heating and cooling bodies especially radiant systems (till 2018). 3) To verify in laboratory climatic chamber the impact of control based on new virtual temperature to thermal comfort and energy consumption for control of 5 types of heating and cooling bodies (till 2019).
