A system has a power source connected to power access points and at least one environmental control system. A threshold compare device is effective to compare the proportional load on the environmental control systems to a preset threshold. If the threshold is exceeded, unused power access points are disabled. This prevents such access points from placing additional loads on the environmental control systems. Conversely, when the proportional load on the environmental control systems drops below a preset threshold, power can be restored to the disabled power access points. A master control unit can monitor the load on the environmental control systems and either or both the environmental conditions in environment zones or the power loading of the power access points and determine whether to disable unused power outlets.
