QUANTIFYING THE EFFECTS OF ZONED COOLING SYSTEMS ON HOUSEHOLD PEAK ELECTRICITY DEMAND
Bartosz Lomanowski, Kamel HaddadAbstract: In this study, the potential benefits of a zoned cooling system during peak summer days are examined through the use of a building energy simulation model. The model presents a means for evaluating various cooling control strategies to quantify the effects of a zoned system on the reduction and shifting of household peak electricity demand. The development and theoretical basis of the model are summarized. Simulations were carried out on a model representative of the (CCHT) Canadian Centre for Housing Technology houses. Results for selected control strategies are presented for a hot, humid and sunny peak summer day in Southern Ontario. The simulation results suggest that a gradual thermostat set-point increase during the peak cooling period may be ineffective if the system is undersized for peak summer conditions. The use of external shades was shown to significantly reduce the sensible cooling load allowing an otherwise undersized system to fully meet the cooling demand. Such a passive measure would likely increase the effectiveness of the zoned cooling control strategies examined.
