Delivering Successful LED and Energy projects
Ken Carter

Intro • Involved with energy reduction and management for 20
years: in Steel Industry/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…..
Three Core Principles
GET
THESE
RIGHT
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 important
Contractor typesEnergy 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 required Poor housekeeping
Project team involved with energy reviews Few links to energy savings
Contractor Types
Lighting - LEDs
Choose fittings based on the following • Warranty: Hidden terms (5yr – only
mech, %age failure per fitting)• Driver/led combinations: Philips Tridonic highest efficiency. • Lm/W – currently up to 120-130 delivered.• Supplier should be delivering a lighting
solution not pushing fittings onto you.
Further Considerations
• Lamp angles: Often offer single product per application.• Existing lux/fittings: =Start again to save the most energy• Where 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 lighting
Wrong Choice !?
LED Control - Overlooked
Building Management Systems
• Large BMS upgrade project costing millions• Increases in energy throughout
• Project management - Not run by energy department• Not technology issue – high specification equipment • Contractor - previously not energy related.• Task driven roll out
WHY?
Measurement
• Quite a science. But start simple. • Basic assessments and sense check• Relationship to weather, production, occupancy.• Use of sub meters/temp meters/current clamps• Sample sites a good tool• Work out risks early on: fixed savings vs. variable savings• Step in and stop projects that are not delivering• Other issues causing increases in energy
Simple
More Complex
Management - Starting project
• Assess project • Contractor assessment• Design project• H2 measure• Who is ultimately responsibly for energy? • Prioritise best sites for part year effect.• Links to FM - what can energy deliver for FM• O&M
Management financials
• kWH 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.
Sign offs and handovers
Expect good documentation for FM
O&M
Drawings
Warranty info
Protects installer and informs maintainer
Ensure FM available for handover
