- 158 MWh measured energy saving
Proof that optimisation is delivering results
myCoreAI continuously optimises HVAC every 15 minutes using live building behaviour, occupancy patterns and weather conditions, typically reducing HVAC electricity consumption by 20–35% without the need for manual intervention.
myCoreAI is deployed across around 2,000 buildings in 13 countries, with EcoAI providing UK delivery, implementation and client support. EcoAI provides transparent, auditable evidence so building teams can evaluate real outcomes with confidence.
Measured performance example
Measured AI on vs AI off performance
This monthly profile shows weather-normalised AI off and AI on performance for HVAC electricity and heat in a live occupied building. The gap between the lines shows the savings delivered by continuous EcoAI optimisation while normal building operation is maintained.

HVAC savings in practice
How HVAC energy savings are delivered
Continuous optimisation reduces unnecessary HVAC operation while maintaining comfort and appropriate ventilation conditions. The BMS remains the control system, while EcoAI helps reduce avoidable airflow and conditioning demand when conditions allow — and lets output increase again when the building needs it.
1
Reduce unnecessary airflow
When indoor temperature is stable and CO₂ remains low, airflow can operate below the reference level.
2
Reduce fan and conditioning demand
Lower airflow reduces fan demand and the volume of air that needs to be heated or cooled.
3
Keep comfort as the constraint
Airflow rises again when building demand, temperature or ventilation requirements change.
In a reviewed 30-day AHU2 example at Gatty Marine, optimised supply airflow was 27% lower than the reference signal and extract airflow was 22% lower, while average indoor temperature remained at 22.18°C and average CO₂ remained low at 457 ppm.
Example shown is based on AHU2 dashboard data for the reviewed period and should not be read as a whole-building annual saving.
How savings are verified
EcoAI compares building performance against a weather-normalised baseline, including periods with AI optimisation active and inactive. This helps show whether lower energy use is being achieved under comparable external conditions, rather than simply because of changes in weather.
