EDUCATIONAL FACILITIES ADVANCE ENERGY SAVINGS
How can schools reduce energy consumption without major capital investments or compromising occupant comfort?
One Canadian school found an answer by combining its existing building automation system with AI-powered HVAC optimization.
At the school, iBOS energy® delivered a 14% reduction in electricity consumption within the first six months, while helping the facility team identify HVAC issues, improve building control, and maintain comfortable conditions.
The project demonstrated how intelligent building automation can take energy management beyond traditional efficiency measures—and continuously optimize a building in real time.

Why was this P-12 school focused on energy efficiency?
The school had already taken a grassroots approach to reducing energy consumption.
The goal was straightforward: reduce operating costs so more resources could be directed toward students and classrooms.
In its first year of energy-efficiency efforts, the organization achieved approximately $300,000 in savings with little to no capital investment. It subsequently maintained annual savings of approximately 20–25%, surpassing $1 million in cumulative savings in less than four years.
For the school's operations team, the opportunity was about more than reducing utility costs. Energy savings could be redirected toward improving the student learning experience, classroom resources, and support.
The next opportunity was to move from manually implemented efficiency measures toward automated, data-driven energy optimization.
What makes a hvac system more efficient in a school?
School buildings are dynamic environments.
Occupancy, equipment use, weather, solar gains, ventilation requirements, and internal heat loads can all change throughout the day. Hundreds of students may arrive within a short period, cafeteria equipment may turn on, classroom equipment generates heat, and outdoor conditions can change rapidly.
All of these factors affect both indoor comfort and energy consumption.
Traditional building management systems (BMS) can respond to programmed conditions, but the challenge is determining how those controls should continuously adapt as building conditions change.
The school's operations team recognized the opportunity for an automation system that could respond to these constantly changing conditions.
That was the opportunity the team saw in EcoPilot's technology.
“Finally! We have identified a tool that will consider those factors, plan for them and intelligently control our building management system (BMS) to allow for automatic and continuous energy savings.”
What is AI-powered HVAC optimization?
AI-powered HVAC optimization uses software to continuously analyze building conditions and adjust HVAC controls to reduce energy consumption while maintaining a defined comfort range.
EcoPilot's iBOS® technology acts as an intelligent optimization layer for a building management system.
Rather than replacing the existing BMS, iBOS® works with the building's existing controls and continuously evaluates factors such as:
- Building thermal characteristics
- Weather forecasts
- Outdoor conditions
- Real-time indoor temperatures
- Heating and cooling requirements
- HVAC operating conditions
- Defined occupant comfort ranges
The system then makes automated adjustments to HVAC operation.
At the Canadian school, iBOS® evaluated these conditions and provided control adjustments to the BMS every two minutes.
The result was a more dynamic approach to HVAC control: instead of simply following fixed setpoints, the system continuously optimized operation based on what the building actually needed.
How was iBOS® implemented at the school?
The school was selected for the project because it met the requirements for an energy-efficiency rebate.
EcoPilot proposed dividing the building into four control zones based on the areas served by the existing HVAC systems.
The project included intelligent control of:
- Air Handling Units (AHUs)
- Electric baseboard heaters
- Silicon Controlled Rectifiers (SCRs)
For the AHUs, iBOS® adjusted the existing supply-air temperature setpoints to reduce heating energy while keeping the areas served by each unit within a predefined comfort range.
For the electric baseboards, iBOS® adjusted the SCR signal between 0–100% to reduce electricity consumption while maintaining the desired temperature range within each zone.
The original project analysis estimated that the AI-based optimization could produce approximately 11% annual electricity savings, equivalent to about 4 MWh.
The actual results exceeded that initial estimate.
How can we reduce energy consumption at school?
EcoPilot's iBOS® system went live at the school on October 1, 2019.
Installation began during the summer, and much of the technical work was completed remotely, helping minimize disruption to school operations.
After six months of operation, from October 2019 through March 2020, the p-12 school reported:
14% electricity savings
That result was particularly significant because the project was designed to optimize the school's existing HVAC infrastructure, rather than requiring a major equipment replacement.
There were also no reported comfort complaints during the measured period, an important consideration for any HVAC energy-efficiency project in a school.
For the school's operations team, the results demonstrated that energy savings and occupant comfort did not have to be competing objectives.
What HVAC problems can AI-powered building optimization identify?
One of the additional benefits of the project was iBOS®'s ability to identify operational problems within the building's HVAC systems.
1. A malfunctioning mixed-air damper
iBOS® identified that the mixed-air damper in one AHU was not modulating as commanded by the building automation system.
An inspection found that the actuator motor had become disconnected from the damper.
The issue could potentially have remained undetected without the additional system-level monitoring provided by iBOS®.
Repairing the damper helped improve system operation, energy performance, and occupant comfort.
2. AHUs starting simultaneously
The system also identified that the school's AHUs were starting at the same time.
Simultaneous startup can increase electrical demand and contribute to higher peak loads.
Identifying this operating pattern created an opportunity to better coordinate equipment startup.
3. Heating elements operating at 100%
iBOS® identified that SCRs associated with the AHUs were quickly reaching 100%.
This could result in excessive heating of the supply air and increased energy consumption.
The finding provided the school's facility team with another opportunity to improve HVAC control and reduce unnecessary energy use.
Why is continuous HVAC optimization important?
Traditional energy-efficiency projects often focus on installing more efficient equipment or implementing a specific operational change.
Those measures can produce meaningful savings, but building performance can change continuously.
Equipment can malfunction. Weather changes. Occupancy changes. Control sequences interact in unexpected ways. Building use evolves.
Continuous optimization provides a way to respond to those changes automatically.
Instead of relying exclusively on periodic inspections or manual adjustments, an intelligent optimization system can continuously monitor building conditions and make adjustments throughout the day.
For building managers, this can mean less time spent manually tuning HVAC systems and more visibility into how the building is actually operating.
What does AI add to a building management system?
A BMS provides the underlying control infrastructure for a building.
AI-powered optimization can add another layer of intelligence by continuously analyzing building conditions and determining how existing HVAC equipment can operate more efficiently.
For the school, that meant moving from traditional energy-efficiency initiatives toward a more automated approach.
The objective wasn't to replace the BMS.
It was to make better use of the systems and equipment already in place.
How does AI-powered HVAC optimization support building managers?
For facility and energy managers, automation can reduce the amount of manual intervention required to maintain energy performance.
At the school, iBOS® operates continuously in the background while providing visibility through its software dashboard.
The dashboard provides information about:
- Real-time energy performance
- Building comfort
- Zone conditions
- Temperature trends
- Areas outside the desired comfort range
- Potential operational issues
An interactive floor plan and heat map provides a visual overview of building performance and allows users to investigate individual rooms or zones.
This gives facility teams another tool for identifying problems and understanding why a particular area may not be performing as expected.
What does this mean for schools and other large buildings?
The project demonstrates that energy optimization doesn't necessarily require replacing existing HVAC equipment.
Buildings with existing BMS infrastructure may be able to improve performance by adding an intelligent optimization layer that continuously adjusts existing controls.
For schools, universities, offices, healthcare facilities, and other large buildings, the potential benefits include:
- Lower energy consumption
- Reduced operating costs
- Improved HVAC control
- Better visibility into building performance
- Identification of equipment and control issues
- Reduced manual intervention
- Potentially lower peak demand
- More efficient use of existing building infrastructure
From energy savings to better building intelligence
For the school's operations team, the value of the project went beyond the 14% electricity savings.
The organization was able to use the same building infrastructure while adding a layer of automated intelligence to its HVAC systems.
The technology allowed the school to pursue energy savings continuously while also identifying equipment issues and supporting building operations.
And ultimately, the purpose of those savings remained the same: putting resources back into the classroom.
