Heating and cooling degree days

Description

  • The number of population-weighted heating degree days (HDD) decreased by 8.2 % between the 1951–1980 and 1981–2014 periods; the decrease during the 1981–2014 period was on average 9.9 HDDs per year (0.45 % per year). The largest absolute decrease occurred in northern and north-western Europe.
  • The number of population-weighted cooling degree days (CDD) increased by 49.1 % between the 1951–1980 and 1981–2014 periods; the increase during the period 1981–2014 was on average 1.2 HDDs per year (1.9 % per year). The largest absolute increase occurred in southern Europe.
  • The projected decrease in HDDs as a result of future climate change during the 21st century is somewhat larger than the projected increase in CDDs in absolute terms. However, in economic terms, these two effects are almost equal in Europe, because cooling is generally more expensive than heating.
  • The projected increases in the cooling demand in southern and central Europe may further exacerbate peaks in electricity demand in the summer unless appropriate adaptation measures are taken.
