VENTILATION EVALUATION SYSTEM AND VENTILATION EVALUATION INDICATOR

PROBLEM TO BE SOLVED: To provide a ventilation evaluation system which indicates a judging index available for objective comparison by analyzing ventilation states at respective openings of a building such as a house, and strategically sets the openings and evaluates the set openings, and to provide a ventilation evaluation indictor for use in the system. SOLUTION: According to a representative structure of the ventilation evaluation system, a number of external wind directions are set in the building having the plurality of openings, and the ventilation states at respective location in a room caused by different external wind directions are calculated, followed by superimposing the ventilation states on each other, to thereby calculate a synthetic ventilation state of the building.
