Delivering Successful LED and Energy projects

Intro
Involved with energy reduction and management for 20 years: in Steel I
ndustry/Consultancy/Retail /Contracting.Seen millions of pounds invested: CHP, HVAC, Lighting, Voltage, Refrigeration etc.
Projects succeed or fail unless all three ‘ Core Principles’ are adhered to…..Slide3
Three Core Principles

Characteristics of Bad Projects
Poor
planning: Financials guessed at or made up
No
measurement: Pre
, during or post
Not enough sense checking of basic numbers
Too late to
stop: Money
spent , ROI unknown
Poor
contractuals
Contractors:
choice is importantSlide5
Contractor types
Energy contractors
‘Non-energy’ contractors
Team players
Elusive during project – project plan sketchy
Looking
for continuation projects (based on success)
Move from site to site quickly
See projects through to handover
Task driven not energy driven
Increase
scopes/fact
find
Seldom commission for savings
Minimal
impact during works
No scope widening or common sense
Return visits as requiredPoor housekeepingProject team involved with energy reviewsFew links to energy savingsSlide6
Contractor TypesSlide7
Lighting - LEDs
Choose fittings based on the following Warranty: Hidden terms (5yr
– only mech, %age failure per fitting)Driver/led combinations:
Philips
T
ridonic highest efficiency. Lm/W – currently
up to
120-130
delivered.
Supplier should be delivering a lighting solution not pushing fittings onto you.Slide8
Further Considerations
Lamp angles: Often offer single product per application.
Existing lux/fittings: =Start again to save the most energyWhere possible over populate &
under run
LED’s
Integral emergencies lights & control.End of year efficiency will level off
(
2
% per ¼ at
moment)
Be aware of extra costs associated with EM
lighting
compliance (can go from under to over lux), breaker upgrades and other control integration.
Essential and non-essential split – sub
ccts and kit hanging off lightingSlide9
Wrong Choice !?Slide10
LED Control - OverlookedSlide11
Building Management Systems
Large BMS upgrade project costing millionsIncreases in energy throughoutProject
management - Not run by energy departmentNot technology issue – high specification equipment Contractor - previously not energy related.Task
driven roll out
WHY?Slide12
MeasurementQuite a science. But start simple.
Basic assessments and sense checkRelationship to weather, production, occupancy.Use of sub meters/temp meters/current
clampsSample sites a good toolWork out risks early on: fixed
savings vs.
variable savings
Step in and stop projects that are not deliveringOther issues causing increases in energy Slide13

Management - Starting project

energy? Prioritise best sites for part year effect.Links to FM - what can energy deliver for FM

cost – simple values may hide true savings. Payments linked to performance/retentions.Additional costs. Capture early on.
Additional benefits also.Assess project value – worse case/median estimate/samples based on fixed/variable project type.Revisions.Slide17
Sign offs and handovers
Expect good documentation for FM
