Applicable Systems
- Primary: Energy
Objective/Method/Outcome
- Objective: Calculate the Heating and Cooling Degree Days using an expert method.
- Method: Heating Degree Days calculated by comparing Heating Degree Days, Cooling Degree Days, and a Temperature baseline.
- Outcome: A calculated Trend Log is generated with the number of Heating Degree Days for the previous 24 hours.
Logic
Heating Degree Days = SUM (Hourly Temp - Base Temp) / 24 Cooling Degree Days = SUM (Base Temp - Hourly Temp) / 24
Notes
Base Temperature is 18 deg.C (can be changed in the Logic Flow, Block number 8). This formula only works with SI units.
Inputs
- OAT {sensor, outside, air, temp}
