THE VALUE OF SMART METER DATA
Predict energy use/costs
Detect mal function or anomalies
Interact with energy grid/district
Identify user behaviour
……………..
“DeltaT, predictor for heating”
“Date-time, predictor for occupant behavior”
“Other influential factors are minor”

ENERGY PERFORMANCE AND OCCUPANT BEHAVIOUR
• Indoor minus Outdoor temperature (DeltaT)
is key
• Date-time also indicator
