10. OPTIMISATION
Night Time Purging
Expel heat build up during early hours of the morning to reduce the cooling load required to prepare
the building for customer occupancy.
3% energy reduction
Adaptive start/stop optimiser
Making plant operation visible

11. FACILITIES MANAGEMENT
Ventilation Fan Control
Changes in building occupancy requires an update of many HVAC systems.
In this case the ventilation fans required switching off outside of customer occupancy; saving over £3,000 PA.
BEFORE AFTER

12. ASSET UPGRADE
Upgrading Assets
Replacing existing assets with new energy efficient technology can deliver considerable cost saving,
cut maintenance costs and improve the customer environment.
Strategic planning for upgrading assets
No single technology solution
Some projects can influence others
Add additional control wherever possible

13. BEHAVIOUR AND MEASUREMENT
OPTION 1: BEFORE AND AFTER
LED Upgrades
OPTION 2: SYSTEM MEASUREMENT
Variable speed drives, lighting PIR,
boiler replacement
OPTION 3: WHOLE BUILDING
BMS strategy changes, multiple
projects

14. • Blended solution incorporating
optimisation, asset upgrade,
maintenance and behavioural change
• Energy savings of over 9% realised -
7.2 million kWh / over £400,000
• Pilot exit rate of 15.1%
• Validated by collaborative M&V &
transparent.
RESULTS
• Improved understanding of building
performance, robust analysis and
monitoring
• Improved engineer engagement
and up-skilling
• Clear messaging to multiple
stakeholders
• Turn data into action.
ENERGY SAVING RESULTS
THE BENEFITS

15. KEY TAKEAWAYS
• Moving away from a typical client / service partner
relationship to a collaborative partnership allows
ambitions to be aligned and targets shaped
• Buildings require continuous fine tuning and optimisation
• Savings do not come from gadgets and gizmos but a
blend of activities combined
• Data is useless unless it is acted upon
• Stakeholders must be engaged
