One of the core objectives of the commissioning process is to ensure that the dynamic systems
function correctly. Just as important, if not more so, is enabling the correct function of those
systems throughout occupancy. While verification strategies vary, it is clear that examination of
actual operation produces the most accurate results. This is accomplished through trend logging.
With analysis of regularly recorded control point data through visualization (including graphs,
charts, etc.), a quick and accurate diagnosis of incorrect or less than optimal operation can be
assessed. However, several questions arise regarding this process: What data should be
visualized? What form should this visualization take? How can data from several different yet
interrelated control points be best compared? Finally, what patterns within a visualization should
be sought
