Heating Degree Days vs Fuel Bill Calculator

Calculate expected heating fuel consumption from heating degree days (HDD). Normalize utility bills for weather variation to track true energy efficiency over time.

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

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)

How It Works

Calculate expected heating fuel consumption from heating degree days (HDD). Normalize utility bills for weather variation to track true energy efficiency over time

Each component has a specific meaning:

  • Heating degree days — The heating degree days recorded for the patient or scenario being assessed.

Note: Interpret the hdd fuel bill result against the clinical thresholds and context described above.

How to Use

Enter the heating degree days for the patient or scenario you are assessing. Calculate expected heating fuel consumption from heating degree days (HDD). Normalize utility bills for weather variation to track true energy efficiency over time. Use the hdd fuel bill result to inform your clinical assessment.
