... is also slightly reduced during the early night hours (i.e., after the building's operation hours) due to the cooling energy stored and released by the building's thermal mass. For example, when the precooling control strategy is applied for 9 h, the building's thermal mass has more time to store cooling...

... of renewable energy sources. Demand-controlled ventilation (DCV) and building thermal mass control can individually and jointly provide such flexibility. The performance and financial payback of these technology options can be dramatically improved if based on hourly electric prices and carbon emissions rates...
