A computer implemented environmental process control apparatus (10, 110) for displaying the condition of selected attributes of (n) plurality of environmental control components or zones (38, 40, 42, 138, 140, 142) within a facility. In one embodiment, the apparatus (10) is configured to create a river to time display (14) including a rivulet (15) having an historical (16) and future data segment (22) corresponding to each of the plurality of components or zones (38, 40, 42). In another embodiment, the apparatus (110) is adapted to display the magnitude of the departure of a measured value (167) from a set point (193), a rate of change of the departure value (169), or a second measured value (171) for each or several of the plurality of zones or components (138, 140, 142).
