Abstract

In a method for manipulating environmental conditions in an infrastructure containing one or more adaptive vent tiles, correlations between opening levels of the one or more adaptive vent tiles and an environmental condition at one or more heat dissipating devices are identified. In addition, one or more environmental conditions at locations proximate to or within the one or more heat dissipating devices are received and errors between the received one or more environmental conditions and one or more reference environmental conditions are identified. Moreover, opening levels for the one or more adaptive vent tiles are determined based upon the identified correlations and errors.
