Degree Days Calculator

Calculate heating degree days (HDD) and cooling degree days (CDD) from daily temperatures. Base temperature 18.3°C (65°F). Annual HDD/CDD for energy use benchmarking and fuel consumption estimation.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How It Works

Calculate heating degree days (HDD) and cooling degree days (CDD) from daily temperatures. Base temperature 18.3°C (65°F). Annual HDD/CDD for energy use benchmarking and fuel consumption estimation

Each component has a specific meaning:

  • Daily temperatures — The daily temperatures recorded for the patient or scenario being assessed.

Note: Interpret the degree days result against the clinical thresholds and context described above.

How to Use

Enter the daily temperatures for the patient or scenario you are assessing. Calculate heating degree days (HDD) and cooling degree days (CDD) from daily temperatures. Base temperature 18.3°C (65°F). Annual HDD/CDD for energy use benchmarking and fuel consumption estimation. Use the degree days result to inform your clinical assessment.
