Perhitungan beban pendinginan pada gedung A lantai 2 Politeknik Negeri Bandung menggunakan metode terbaru yang direkomendasikan dalam standar American Society Heating, Refrigerating, and Air Conditioning (ASHRAE) yaitu perhitungan beban pendinginan RTSM (Radiant Time Series Method). Perhitungan bebannpendinginan RTSM ini berbeda dengan metode yang sudah biasa digunakan yaitu CLTD/SCL/CLF (Cooling Load Temperature Difference/ Solar Cooling Load/ Cooling Load Factor). Cara yang dilakukan untuk mengerjakan perhitungan beban pendinginan metode Radiant Time Series dengan mempelajari buku "Load Calculation Application Manual" Second Edition oleh Jeffrey Spitler buku dari ASHRAE edisi Satuan Internasional. Perhitungan beban pendinginan dengan metode Radiant Time Series dengan luas lantai 2 gedung A yaitu sebesar 999,27 m2 didapat beban puncak berada pada pukul 14.00 dan beban sebesar 139.511,10 Watt.

The calculation of the cooling load on the 2nd floor of the building A of the State Polytechnic of Bandung used the latest methods recommended in the American Society of Heating, Refrigerating, and Air Conditioning (ASHRAE) standards is the calculation of the cooling loads RTSM (Radiant Time Series Method). The calculation of RTSM cooling load is different from the commonly used menthods that are CLTD / SCL / CLF (Difference / Solar Cooling Cooling Load / Cooling Load Factor). The way to do the calculation of Radiant Time Series Method cooling loads by studying the book "Load Calculation Application Manual" Second Edition by Jeffrey Spitler book from ASHRAE. Here used the edition of the SI because the unit unit used in the calculation using the SI unit standard.Cooling load calculation with Radiant Time Series Method with wide 2nd floor A building is 999,27 m2 obtained the peak load is at the time 14.00 and the load is 130.511,10 Watt.
