Energy consumption impacted by climate change application: Case study, Astara

To study past climate conditions, main climatic factor related to the energy consumption namely temperature and precipitation were considered. Heating degree days (HDD), cooling degree days (CDD) and sunshine hours were analyzed. According to all reports in different scales temperature of Astara region, in last half century has been increased. In the longer future time period, the study area will face with higher values of increasing temperature. HDD with base temperature of 18 oC reduced in last 18 years. HDD in January which is cold month also reduced. In the same time CDD increased. CDD in July which is warm month also increased. This is in the same line of increasing the number of sunshine hours in the same time slice. Astara location is included in both of Central Asia and West Asia sub-regions in IPCC AR4. Projection for temperature change in Central Asia sub-region is not in agreement with national and local downscaling results.
