2  Introduction – Project and Partners  Background – Steve Poole  Funding (E.On) – Rupert Butt  Design Challenges (DES) – Paul Fisher  Project Hardware (Projection) – Steve Poole  Outcome – (NRCH) – Dave Guy  Facts and Figures (Projection) – Steve Poole  Conclusions and Questions

3  Background ◦ Project Scope  Replace existing Tungsten light source with LED  Retain the existing lighting points  Recreate exactly the same lighting feel  Compatible with existing DMX control system  Seamless dimming to zero  Viable ROI

4   A program of works where the capital cost is recovered through energy savings which are guaranteed by E.ON £ £ £ £ £ £ £ £ £ Implementation costs (incl. financing ) Ongoing savings Guaranteed savings period Guaranteed savings p.a. Savings in the early years repay the initial capital investment thereby limiting client risk Client net benefit Energy Performance Contracting

5  Nottingham Energy Performance Contract E.ON secured a contract under the RE:FIT Framework to deliver an EPC for Nottingham City Council. £1.2M Investment to deliver a 26% energy saving across 8 buildings, including Leisure Centres, Care Homes and a Sports Stadium. All savings guaranteed for 7 years in order to pay back the original investment. One of the 8 Buildings is the Royal Concert Hall.

6  Design Challenges (DES) ◦ The issues that needed to be resolved  Sourcing suitable product  Existing light fittings  Consistent and effective dimming  Control interface  The building  Emergency Lighting  Commissioning

7  Design Challenges (DES)  Existing Fittings (High Level)  300W Par Lamps

8  Design Challenges (DES)  The Building

9  Project Hardware – AlphaLED ◦ High Level Lighting (20m+ Height)  60 x Bespoke fittings created  Mechanical Interface  2700 CCT – To match tungsten “feel”  3000Lm 28° Beam  For punch and penetration.  Replaced 300W R95 lamps

10  Project Hardware – AlphaLED ◦ Low Level Lighting  458 Down lighters  Across 4 levels.  2700 CCT  Match tungsten feel  700lm @ 11.5 TCW.  Replaced 75W Lamps

11  AlphaLED Attributes ◦ Initial Colour Consistency  1 x 2 step SDCM specification.  Consistent wall washing ◦ Colour Consistency Guaranteed  No colour shift over life  (5 years, 50,000 hrs) ◦ Low Lumen Depreciation  L95 50,000 hrs capability

12  Control Gear ◦ DMX Capable – Dim to Zero Light level  EldoLED Powerdrive.

13 Outcome – Theatre Prospective LED/energy saving houselights and dimming, the bottom 10% Maintenance and consumable savings (700 bulb changes a year previously) Audience reaction to the change

14  Facts and Figures Nottingham Royal Concert Hall - Energy Usage Power (W) Qty Total WTotal kW Existing Fittings / Lamps Removed 300W Par 56 300 60 1800018 75W R95 75 458 3435034.35 Total 52.35 New AlphaLED Product Installed Bespoke Atrium 28 Deg Beam 3000lm CRI80+ 2700K 46.1 60 27662.766 Atrium with astral bezel 700lm CRI80+ 2700K 11.5 458 52675.267 8.033 KW Saving 85% saving 44.317

15  Facts and Figures ◦ The comparison is made assuming the lighting is used in the same way as the existing lighting. In Use Energy Consumption kW Hrs / Day No DaysTotal Kwh Existing 52.35 14 345252850.5 New Lighting 8.033 14 34538799.39 Kwh Saving 214051.11

16  Use control for further energy savings ◦ Tungsten to LED – saves 85% energy Further energy Savings are possible: ◦ LED with DMX allows for various dimming profiles ◦ Set 100% for Theatre Customer use ◦ Set 65% for cleaning ◦ Set 50% at other times ◦ These are examples only

17  Possible to double the saving ◦ Don’t forget to consider use and control In Use Energy Consumption kW Hrs / Day No DaysTotal Kwh Existing 52.35 14 345252850.5 New Lighting 100% Level 8.033 4 34511085.54 New Lighting 65% Level 8.033 5 3459007.00 New Lighting 50% Level 8.033 5 3456928.46 Total 14 27021.00 Kwh Saving 225829.50 Additional Saving with dimming profile 187030.11 Original Saving 214051.11 Total saving 401081.22

18  Conclusions ◦ Substantial Energy Savings are possible ◦ Light Quality can be matched ◦ Day to day maintenance eliminated ◦ Further substantial savings with controls ◦ Hardware guaranteed 5 years 50,000hrs

19  Any questions ? Thank You AlphaLED Stand D11
