Patent ID: 8190367

Claim:
A method for minimizing levels of air pollution in a non-monitored remote enclosed structure in an urban area, said method comprising the steps of: a. using no less than two independent air pollution monitoring stations and at least one computing center, continuously gathering outdoor air pollution data and detecting variable frequent fluctuations of outdoor air pollution levels which recur within the day; b. transmitting said data gathered by the monitoring stations in real time to the computing center; c. routinely and in real time, analyzing said gathered data in said computing center to identify relative levels of air pollution from at least two specific locations in said urban area; d. based on said identified relative levels of air pollution, identifying synchronizations and dependencies of relative air pollution levels between at least two different locations of the urban area; e. determining a relative influence factor for each monitoring station regarding its relative influence in calculating air pollution relative levels for different non-monitored locations of the urban area; f. based on said synchronizations or dependencies of relative levels and on said determined factor, identifying relative minimal levels of outdoor air pollution, by calculating ratios between air pollution levels measured in different points in time for at least one remote structure which does not include an outdoor monitoring station; and g. ventilating the remote enclosed structure that its outdoor surroundings is not being independently monitored with outside air, during periods of minimal levels of air pollution thereby reducing air pollution concentration inside the structure.
