Analyses the effect of various fan system control strategies on energy consumption for a high-rise office building. Describes energy consumption estimates made for each strategy at five different locations using the Building Loads Analysis and Systems Thermodynamics (BLAST) program. States that except for hot, humid climates, a simple economy cycle with a proportional plus integral control system for the cooling coil and outdoor/return air dampers showed low energy consumption. Finds that cold deck reset was also somewhat effective but increased fan power consumption significantly.
