PURPOSE: To perform an effective utilization of surrounding air, estimate an operation mode and display it for improvement of a comfortable feeling of an occupant in a building by a method wherein a body feeling temperature when a thermal environment outside the building is taken into the thermal environment in the building is estimated and calculated with a virtual body feeling temperature model and it is judged if this value is within a predetermined condition or not. CONSTITUTION: A content and a date of event are inputted in advance through a key-board 58 and stored in a RAM 34. ET* is set as a control parameter. However, a relation of the content of the event, its date, the number of customers or the like and ET* set value is stored in advance in a ROM 32. Then, a surrounding air temperature at the specified day is estimated, an internal calorific valve is calculated in reference to the number of customers, momentum of the customers, and the calorific valve of equipments and then the natural ventilation air volume when the opening is opened and the ET* acting as the body feeling when the natural ventilation is carried out are estimated and calculated in reference to the internal heat generation rate and the surrounding environmental value. When the ET* calculated value is within a comfort range, it is displayed at the display 56 that the natural ventilation is to be performed. Accordingly, it is possible to improve a comfortable feeling. |
