AI USE CASE
Smart Building Energy Optimization
Reduce building energy costs by 20–30% using ML-driven HVAC, lighting, and elevator control.
What it is
Deploy machine learning models fed by IoT sensors to dynamically optimize HVAC, lighting, and elevator systems based on real-time occupancy patterns and weather forecasts. Buildings typically achieve 20–30% reductions in energy consumption, translating to tens of thousands of euros in annual savings per property. The system learns seasonal and usage patterns over time, continuously improving efficiency without manual intervention. Payback periods of 12–24 months are common in mid-to-large commercial properties.
Data you need
Historical and real-time sensor data from HVAC, lighting, and elevator systems, plus occupancy data and external weather feeds.
Required systems
- erp
- data warehouse
Why it works
- Ensure full IoT sensor coverage across all controlled systems before model training begins.
- Integrate with existing BMS via open protocols (BACnet, Modbus) to avoid costly hardware replacement.
- Involve facility managers early to build trust in automated recommendations and reduce manual overrides.
- Set up automated model retraining on a regular cadence to capture seasonal shifts.
How this goes wrong
- Legacy BMS (Building Management Systems) cannot expose sensor data via APIs, blocking integration.
- Sparse or unreliable IoT sensor coverage leads to poor model accuracy and suboptimal control decisions.
- Facility staff override automated controls manually, undermining optimization gains.
- Model performance degrades seasonally if retraining pipelines are not maintained.
When NOT to do this
Do not deploy this system in older buildings with fragmented or analog control infrastructure where retrofitting IoT sensors would exceed the projected energy savings.
