2 Lighting technologies

3 Global impact of lighting products Lighting responsible for 15%of global electricity consumption More than the combined output of the world s nuclear power stations Overnight switch to LED lights globally could remove need for 250 coal fired power plants tomorrow Source: CEM, 2015

4 Segmentation of lighting technologies used by EU Regulations Domestic sector (household) Non-directional Directional All lighting Tertiary sector (commercial) Office Street

5 Domestic non-directional lighting technologies Incandescent a.k.a. GLS Halogen CFL LED 200 lumen 200 lumen 200 lumen 200 lumen 40 W 28 W 11 W 2 W 1,500 hrs 2,500 hrs 15,000 hrs 25,000 hrs Banned (still available) 2.00 Phase out

6 Directional or Non-directional? Source: Lighting Europe, 2013

7 Domestic directional lighting technologies Incandescent (GLS) Tungstenhalogen (MV and LV) LED 400 Lumens 400 Lumens 400 Lumens 40 W 40 W 6 W 1,500 hrs 2,500 hrs 25,000 hrs

8 Commercial lighting technologies Commercial lighting is available in a very wide range of types and sizes Correspondingly, lumens, watts and prices vary widely too

9 Related equipment can be sold separately or be integrated into products Lamp holder Ballasts Control gear Luminaire Fluorescent lamp starters

10 Street lighting technologies HighPressure mercuryvapour High Pressure Sodium Metal halide LED 24,000 lumens 27,500 lumens 36,000 lumens 15,000 lumens 500W 250 W 400 W 150 W 18,000 hrs 18,000 hrs 12,500 hrs 75,000 hrs Rel.inexpensive, mercury! Rel. inexpensive Rel. inexpensive Rel. expensive

11 Electricity Consumption for Lighting EU-28, TWh in 2013 (VHK, MELISA model) TWh Largest energy user in lighting is Linear Fluorescent 35% Second largest user is high-intensity discharge (HID) 17% Compact fluorescent is also significant with 7% of energy

12 The Future is LED LED bulbs are a far superior technology Prices are falling Light quality is improving Efficiency is improving Lifespans are at least 10x greater than incandescent and halogen bulbs

13 Growing LED market

14 Industry refocus to LED

15 COP21 10 Billion LEDs Goal Announced on 7 December, 2015 at COP21 Commitments from China, India, US, Ikea Group Support from Phillips, Osram, Cree

16 Harmonised European Measurement Standards What are measurement standards? What are harmonised measurement standards? How are they used? Are there any relevant to lighting?

17 European Measurement Standards Relevant to Lighting There are a lot of measurement and performance standards in Europe Developed by CEN, CENELEC, ETSI European standard bodies EN 60064: Tungsten filament lamps for domestic and similar general lighting purposes - Performance requirements. EN (2004), Lighting applications Measurement and presentation of photometric data of lamps and luminaires Part 1: Measurement and file format EN (2004): Light and Lighting Lighting of indoor work places. EN (2002): Light and lighting -Basic terms and criteria for specifying lighting requirements pren (2006): Energy performance of buildings - Energy requirements for lighting. EN : Road Lighting. Calculation of performance EN : Road Lighting. Methods of measuring lighting performance EN : Luminaires Part 1 : General requirements and tests EN : Luminaires Part 2-3 : Particular requirements Luminaires for road and street lighting EN 60901: Single-capped fluorescent lamps Performance specifications EN : Double-capped fluorescent lamps -Performance specifications. EN 60921: Ballasts for tubular fluorescent lamps Performance requirements EN : Measurement Method of Total Input Power of Ballast-Lamp Circuits. EN 60923: Auxiliaries for lamps Ballasts for discharge lamps (excluding tubular fluorescent lamps) Performance requirements EN 60927: Specification for auxiliaries for lamps. Starting devices (other than glow starters). Performance requirements EN 60929: AC-supplied electronic ballasts for tubular fluorescent lamps Performance requirements EN : Auxiliaries for Lamps -Capacitors for Use in Tubular Fluorescent and Other Discharge Lamp Circuits -General and Safety Requirements EN 61167: Metal halide lamps Performance EN 62035: Discharge Lamps (Excluding Fluorescent Lamps) - Safety Specifications

18 Example energy saving potential 10x the amount of energy/cost using Halogen versus LED downlights Lamp level (x1) LED (4W) Household level (x15) Halogen (40W) 1000 hrs/yr 1,000 hrs/yr 4 kwh/yr 40 kwh/yr 0.48 per year 4.80 per year LED (4W) Halogen (40W) 1000 hrs/yr 1,000 hrs/yr 60 kwh/yr 600 kwh/yr 7.20 per year per year

19 Example energy saving potential 10x the amount of energy/cost using Halogen versus LED downlights UK level (30M households) LED (4W) Energy saving potential: 16,200 GWh / yr Cost saving potential: 1.94 Billion / yr Halogen (40W) 60 kwh/yr 600 kwh/yr 1,800 GWh/ yr 18,000GWh/ yr 216M/ yr 2,160M / yr V. simple assumptions! No time profile, no discounting

20 Time Profile Policy appraisal period Start depends on product lifetime Stock versus flow 1980 sales = 1M bulbs Assume 1 year lifetime Normal distribution assumption

21 Energy saving potential: Georgia How do we do it? Scenario analysis Baseline Policy options

22 Example outputs Increasing energy consumption over time (due to GLS/ halogens) Various policy scenarios show decreases due to phase out of GLS/low efficiency halogens and uptake of LEDs

23 Energy saving potential: Georgia Data inputs (for each technology) Stock/sales (units per annum) Usage(hrs per year) Lifespan (years) Average unit energy demand (W) Average price per unit (GEL) Discussion on data sources on Day 2

24 Example outputs Business as usual (BAU) High uptake of directional halogens Ecodesign impacts GLS phased out by 2014 LED market share greater than BAU

25 Cost benefit analysis What is it? How to do it?

26 Cost benefit analysis Direct vs indirect costs and benefits Proportionate approach Typical costs and benefits: Type Direct impacts from Ecodesign Regulations Cost Benefit Benefit Benefit Marginal product price Value of energy saved Value of CO2e emissions avoided Value of improvements to air quality

27 Example outputs Assume manufacturers pass costs to consumers Heat replacement effect Discounted using 3.5% rate (UK Govt. requirements) CO2 and AQ benefits use UK Govt. provided valuations.

28 Heat Replacement Effect Used for domestic settings More efficient light products = less waste heat Heat system needs to top up due to reduced waste heat Factors developed by UK s Market Transformation Programme

29 Sensitivity Analysis Used for data inputs with low confidence Allows creation of a range of outputs in addition to a central value Ex. Potential energy savings of 5-10 GWh per year instead of 6.78 GWh

30 Example outputs 250 Sensitivity test: Change usage inputs (+10%, -10%) 200 GWh OCBA OCBA maximum OCBA minimum Year Simple illustration of sensitivity test of use values and their impact on energy savings.
