Applicable Systems
- Primary: Energy
Objective/Method/Outcome
- Objective: Calculate the Heating and Cooling Degree Days using an intermediate method (Daily Mean OAT)
- Method: Heating Degree Days calculated by comparing temperature base with maximum and minimum temperatures.
- Outcome: A calculated Trend Log is generated with the number of Heating Degree Days for the previous 24 hours.
Logic
Heating Degree Days = Temp base - Mean Temp Cooling Degree Days = Mean Temp - Temp base
Notes
Base Temperature is 18 deg.C (can be changed in the Logic Flow, Block number 8). Changing the Value of this block allow to use different units.
Inputs
- OAT {sensor, outside, air, temp}
