Edge AI + IoT Solution for HVAC Energy Saving

From scheduled HVAC operation to dynamic cooling optimisation.

AI CORE+ helps commercial buildings reduce HVAC energy consumption by using connected building data, additional IoT sensing and edge AI processing — so HVAC responds to real heat load, occupancy changes and comfort conditions, not just the clock.

The Problem

Fixed schedules do not match real heat load

Many buildings still operate HVAC mainly based on fixed schedules, fixed setpoints and pre-set BMS control logic. However, real cooling demand changes throughout the day.

Clock-based operation vs. real building demand

What drives real building demand?

Hover or tap a factor to see how it changes cooling demand.

What happens when HVAC does not follow actual demand?

Buildings may experience:

Overcooling during low-load periods
Slow response during peak demand
Excessive chiller, pump or AHU operation
Unnecessary electricity consumption
Comfort complaints
Limited visibility of hidden energy waste

The Need

Buildings need HVAC optimisation that can adjust according to actual site conditions, not just the clock.

What Is the CORE?

CORE = Connected Operating & Real-Time Energy Data

The CORE is the connected data foundation of the building. AI CORE+ combines existing system data with added IoT data where needed, so the system can understand real heat load, HVAC energy use and comfort conditions — shifting HVAC from fixed scheduled operation to dynamic, demand-based optimisation.

Existing System Data

CORE Select any data source

Added IoT Data Where Needed

Edge / cloud analytics, machine learning and optimisation engine

CORE

Connected operating and real-time energy data from BMS, HVAC, meters, sensors and occupancy

Plus

Added IoT sensors, smart meters, people-count data, M&V support and ESG reporting readiness

Existing BMS Data + Added IoT Data + Edge AI = Dynamic HVAC Energy Saving

How It Works

Sense. Think. Optimise. Instruct.

AI CORE+ connects existing building systems with additional IoT sensors to understand actual cooling demand and optimise HVAC operation.

Sense real conditions

AI CORE+ collects data from the building CORE, including BMS, HVAC equipment, meters and IoT sensors.

This gives the system better visibility of real-time heat load, energy use and comfort conditions.

Think at the edge

The AI CORE+ Edge Controller processes selected data locally inside the building. It analyses:

Cooling demand pattern
Occupancy behaviour
Weather impact
Comfort conditions
Equipment performance
Energy consumption trend

Optimise dynamically

AI CORE+ supports approved optimisation actions such as:

Reducing unnecessary cooling
Matching cooling output with actual demand
Improving equipment sequencing
Supporting smarter start / stop strategy
Optimising setpoints within agreed comfort limits

Instruct the BMS safely

Approved optimisation instructions are sent to the existing BMS through an authorised communication path.

The BMS remains the primary building control system.

More Than Cloud IoT Monitoring

Intelligence inside the building

Many AIoT systems mainly send data to the cloud for dashboard display. AI CORE+ adds edge intelligence inside the building, enabling faster, safer and more cost-effective HVAC optimisation.

Cloud dashboard

Your building

Data goes out. Charts come back.

Data is sent to the cloud mainly for dashboard display. Every decision depends on the connection, and compute costs grow with every data point.

Decisions are made where the data lives.

Selected data is processed locally by the Edge Controller. Cloud becomes optional — for dashboards and reporting — not a dependency for optimisation.

Why edge AI matters

Local intelligence

Lower cloud cost

Better cybersecurity

Faster response

Improved reliability

Secure BMS Integration

Works with your BMS — never around it

AI CORE+ connects with existing BMS systems through approved communication methods, without hacking, bypassing or replacing the BMS.

HVAC Energy Saving Verification

HVAC savings need proof

Customers need measured evidence before wider deployment. Our M&V-based proof-of-savings support verifies selected HVAC energy-saving technologies with smart metering, environmental logging and clear reporting. Simple. Local. Practical.

What customers ask

Is the saving measurable?

Yes. Selected HVAC equipment or circuits are measured with smart energy metering, and technology ON and OFF periods are compared directly.

Can we test first?

Yes. A proof-of-savings test on selected equipment comes before any wider deployment decision.

Will comfort remain stable?

Indoor temperature is monitored throughout the test, with humidity data where supported, so comfort is reviewed alongside energy.

Can we avoid unnecessary metering cost?

Yes. After the test, scaling uses selected monitoring points — smart meters and full sensor sets do not need to be installed on every device.

Can we avoid BMS control risk?

Yes. For verification deployment the system is monitoring-only: it does not control the BMS, send BMS commands or override existing logic.

Can we get clear verification data?

Yes. Measured site data is converted into a practical verification report with raw data extract, for customer, engineering and audit review.

Savings Calculation

Try the savings formula

Illustrative only. Results depend on site conditions, test boundary, and agreed M&V method. Short-period M&V is practical when the saving signal is material and the operating pattern is stable.

Scaled Monitoring

Scale with cost control

After proof-of-savings testing, wider deployment can be reviewed with selected monitoring points. Smart meters and full sensor sets do not need to be installed for every device.

6 of 36 units metered

Representative HVAC energy data from selected points, plus indoor condition monitoring at key areas, supports estimation of wider HVAC impact.
