style='font-size:10.0pt;font-style:italic'>The results of the comfort surveys
in the two test buildings indicate that occupant comfort was maintained in the
pre-cooling tests as long as the room temperatures were between 70 and 76oF.
Night-time pre-cooling was found to have varying effects on the magnitude of
the following day’s peak demand, with a number of factors affecting its
effectiveness. We found it was important to manage the afternoon load shedding
by ramping the zone temperature set-points rather than stepping them up. This
can be particularly important on hot days or in buildings with smaller thermal<o:p></o:p></span></font></u></i></p>

style='font-size:10.0pt;font-style:italic'>time constants, where air
conditioning-related electrical power could “rebound” and exceed
the peak demand typically seen under normal operation. Simulation of the various
reset strategies demonstrated that the exponential temperature reset strategy for
the thermal mass discharge period is the best of all the three thermal mass discharge
strategies studied. The simulation results indicate that pre-cooling has a greater
impact on reducing air-conditioning-related peak period electrical loads than just
raising the zone temperatures during the peak period.<o:p></o:p></span></font></u></i></p>
