Evaluation of night ventilation in a small bakery outlet using the TRNSYS simulation model.

The purpose of this study is to evaluate the use of mechanically driven night ventilation in a small bakery shop by looking at the indoor temperature reduction and energy savings produced by the reduction of the cooling load of air conditioning systems. The results from simulations using a validated model based on the TRNSYS simulation environment demonstrate that night time ventilation can reduce peak daytime temperatures in shops without air conditioning. Where a shop has air conditioning, ventilation at night can reduce the cooling load of the air conditioning system.
