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

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

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

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

• 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

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
