An efficient climate index for reflecting cooling energy consumption: Cooling degree days based on wet bulb temperature

Meteorological Applications, 2021
Cooling energy consumption of buildings is not only used for decreasing temperature, but for dehumidification. Therefore, cooling degree day (CDD) based on only temperature is insufficient for estimating the cooling energy consumption in buildings.
