1. Delivering Successful LED and Energy projects Ken Carter 29/6/2015

2. 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…..

3. Three Core Principles GET THESE RIGHT

4. 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

5. Contractor types Energy contractors‘Non-energy’ contractors Team playersElusive during project – project plan sketchy Looking for continuation projects (based on success)Move from site to site quickly See projects through to handoverTask driven not energy driven Increase scopes/fact findSeldom commission for savings Minimal impact during worksNo scope widening or common sense Return visits as requiredPoor housekeeping Project team involved with energy reviewsFew links to energy savings

6. Contractor Types

7. 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.

8. 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

9. Wrong Choice !?

10. LED Control - Overlooked

11. 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?

12. 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

13. Simple

14. More Complex

15. 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

16. 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.

17. Sign offs and handovers Expect good documentation for FM O&M Drawings Warranty info Protects installer and informs maintainer Ensure FM available for handover
