degree day

• Единица, используемая в метеорологии и технике для измерения отклонения среднесуточной температуры от стандартной эталонной температуры, обычно применяемая для оценки потребности в энергии для отопления или охлаждения.

A unit used in meteorology and engineering to measure the deviation of the average daily temperature from a standard reference temperature, typically used to estimate energy demand for heating or cooling.

   • The heating bill was high due to the large number of degree days this winter.
   • Engineers use degree days to estimate energy consumption for buildings.
   • Cooling degree days are calculated when the average temperature exceeds a certain threshold.
