Background
A large commercial building leveraging CIM’s PEAK Platform implemented a series of CIM strategic recommendations aimed at reducing unnecessary heating energy and gas usage during warmer summer months. The objective was to refine existing heating system configurations to further decrease gas and electricity consumption while maintaining indoor comfort.
Challenge
Although a lockout strategy was already in place for the site’s hot water system, a deeper analysis revealed an opportunity to lower thresholds even further without negatively affecting occupant comfort. The challenge was ensuring the heating system adjusted dynamically based on real-world seasonal conditions while avoiding excessive energy use.
Solution
Using insights from PEAK, the facilities team implemented refined lockout thresholds, preventing unnecessary boiler operation during warm periods. The adjustments led to a reduction of approximately 150 hours of boiler runtime compared to the previous summer, despite weather differing by less than half a degree between the 2 seasons. Additionally, optimising pump schedules resulted in energy savings of approximately 750 kWh.
Impact
- Reduced energy waste: Lowered unnecessary boiler operation, optimizing gas and electricity consumption.
- Improved seasonal efficiency: Lockout thresholds were refined without impacting occupant comfort, ensuring a data-driven approach to HVAC optimization.
- Scalable strategy: This proactive approach can be replicated across other sites to achieve additional savings without costly upgrades.
This success highlights how small, data-backed optimizations can drive measurable energy efficiency improvements while maintaining operational reliability.
