Abstract: Most of commercial buildings are intermittently operated in practice. The use of the Radiant Time Series (RTS) method based on the continuous air-conditioning operation could result in largely underestimated peak cooling loads, and inconsistent design. Hence, a new method is developed based on the RTS. The new method only needs one more step after the current RTS design procedure, using the overall periodic transfer coefficients that have computed in this procedure. The additional cooling loads generated by the new method well agree with the results form EnergyPlus simulations. Analysis results also show that the additional peak cooling loads largely depend on building types, orientations, window sizes, and operation periods.
