Abstract: According to an aspect, a method of thermal management includes capturing one or more thermal images within a temperature-controlled space, using a thermal imaging camera. One or more sources of radiant heat are identified within the temperature-controlled space based on the one or more thermal images. A heat level variation of the one or more sources is determined with respect to an ambient temperature of the temperature-controlled space. A control action of a heating, ventilation, and air-conditioning system is triggered in response to the heat level variation.
