Abstract:

Cooling and Heating Degree Days can be used to reflect the influence of climate factors on energy consumption for building heating and cooling, and also characterize the cold level in heating period and the hot level in cooling period. The Cooling Degree Days (CDDs) are the cumulative number of degrees in which the daily mean air temperature is above a certain reference air temperature within a specified time range. The Heating Degree Days (HDDs) refer to the cumulative number of degrees in a certain time range in which the daily average air temperature is lower than a certain reference air temperature. Based on the Industry Standard on Standard for Energy Efficiency Design of Residential Buildings in Hot Summer and Cold Winter Zone (JGJ134-2001) , temperature 26℃ is taken as the cooling reference air temperature, while heating as 18℃. Based on 2 m air temperature data from ERA5-Land reanalysis meteorological dataset (0.1° x 0.1° spatial resolution), the authors calculated the cooling and heating degree days in north of 18°N latitude of China (1981-2020) on Google Earth Engine platform. The dataset includes the following data from 1981 to 2020: (1) CDDs data; (2) HDDs data. The temporal resolution of the dataset is yearly, and spatial resolution is 0.1°. The dataset is archived in .tif format, and consists of 80 data files with data size of 75 MB (compressed to one file with 17.7 MB).Browse
