Abstract [en]

In the built environment climate control is the most energy intensive component and in trying to reduce energy use, occupant satisfaction is compromised.  Identifying strategies that balance the energy use and occupant satisfaction is important. One strategy is optimizing elevated air movements with intermittent air jet strategy (IAJS). The strategy enhances human convective and evaporative cooling resulting in good indoor climate and low energy use. Understanding the systems cooling capabilities is thus important to justify its practical implementation. In this paper, the potential cooling effect of the strategy is estimated with different calculation methods: thermal manikin measurements, measurements with thermal comfort data logger and estimation of the cooling effect with a web application tool (CBE thermal comfort tool). As shown in this study, the obtained cooling effect may differ by as much as 1 oC between estimation/calculation methods. This may have both implications on energy use and occupant satisfaction.
