1 Energy Efficiency

2 The energy dilemma is here to stay The facts The need Energy demand by 2050 Electrical energy demand by 2030 Source: IEA 2008 vs CO 2 emissions to avoid dramatic climate changes Source: IPCC 2007, figure (vs level) Energy management is the key to address the dilemma 2

3 A simple question? From an energy efficiency point of view is your business opportunity driven more by; Financial considerations or Environmental considerations 3

4 Why save energy? WE MUST REDUCE THE IMPACT OF CLIMATE CHANGE Using less energy will reduce CO 2 emissions Using less energy will save money, reduce operating costs Utilising energy efficient solutions will help job creation Saving energy is socially responsible BUT.. 4

5 The best way to generate energy capacity is to save it Coal 100 units 35 units 33 units 1 unit saved at home 3 units not generated at the power plant 5

6 EE Recommendations, policy and legislation Just some of the initiatives around energy efficiency Energy Performance in Buildings Directive EPC Energy performance certification DEC Display energy certification Building Regulations Part L2 CRC Energy Efficiency Scheme CTS Carbon Trust Standard Climate change agreements Climate change levy Climate change act 2008 EU Carbon trading scheme ECA Enhanced capital allowance BREEAM BRE Environmental Assessment Method Talk to our energy experts to unravel them! 6

9 Measure The importance? Why? Do you know know how energy is being used? Can wasteful energy use and savings opportunities be identified? Can it help meet policy and legislation? How? Simple observation Simple walk through energy audits Energy Action Full energy audits Metering and monitoring Powerlogic/ION Energy bill analysis - Consultancy Infrastructure process and operations audit MP4 Where The deeper the measurement the better the understanding and EE opportunity When Continuously through data collection systems TAC BMS, IONe, EEM and SCADA 9

10 The Electricity Bill Which elements can be important? Consumption charges Energy charges Period comparisons Area comparisons If you understand your energy supply can you make a difference? To your finances To the environment To your system efficiency To your system capacity 10

11 Energy cost evolution Cost per kwh %! Availability charge Supply capacity often more than required Reactive power charge DNOs are charging for power factor < 0.95 lagging Power factor Power factor in commercial premises is often < 0.95 lagging 11

14 Sustaining Energy savings is easy, just follow the 4 Energy Efficiency steps 1 Measure 2 Fix the basics 3 Automate 4 Monitor and Improve 14

15 Fix the basics Can opportunities for savings be implemented? Lighting replacement Power factor correction Passive energy efficiency Behavioural change 15

16 Lighting replacement GET offices Entrance stairway lighting, 24 hr use 50 x 50W MR16 12V + transformers Power consumption 2.5 kw kwh per annum Energy cost per annum 1,409 CO 2 emissions per annum 9.15 tonnes (Potential 200 lamp replacements per year) Solution to install 50 x 1.3W LED GU10 Energy cost savings 1,372 per annum (97%) CO 2 savings 8.91 tonnes per annum (97%) (2 medium sized hot air balloons full of CO 2 or the emissions of 4 company cars) (Potential 0 lamp replacements for 5 years) 16

17 Power Factor Correction is a solution to help you simply reduce energy bills.. Why? The quantity of electric motors, induction heaters, and fluorescent lighting installed in commercial and industrial buildings has increased significantly, reducing the power factor and hence efficiency Using power factor correction reduces: The reactive current drawn from the electrical supply Reactive power charging CO 2 emissions kwh consumption And creates greater supply capacity through more efficient energy use 17

18 Power Factor Correction Existing installation Power factor 0.73 lagging kw 240 kva 320 Target power factor 0.95 lagging Solution to install 150kVAr of power factor correction (PFC) PFC Cost 2,331 Energy cost savings 2,770 per annum Energy cost savings 41,550 (over the lifetime of the PFC) Return on investment > 1 year CO 2 savings tonnes per annum (3 medium sized hot air balloons full of CO 2 or the emissions of 6 company cars) VARSET Up to 600 kvar standard or detuned banks 18

19 Passive energy efficiency through the use of lower loss technologies.. Why? Losses can be reduced by utilising more efficient installation technologies and using equipment with lower losses. Some examples: Similar rating air circuit breakers can have losses 200% higher (the equivalent of leaving a 2 kw electric fire on for 25 years) Busbar trunking can reduce the volume of conductors needed thus reducing losses and reducing installation time maintaining maximum flexibility Low loss transformers substantially reduce cost of ownership over lifetime often >40 years for a transformer 19

20 Fix the basics > behavioural changes Lighting - if your office does not have an occupancy sensor Pester your facilities manager to install one Turn off the light when you go for a meeting, or to lunch, and especially when you go home Computers Turn off your computer at night Set your computer to enter standby or hibernate when unused Don t rely on a screensaver Printing Avoid printing documents whenever possible Print double-sided 20

21 Fix the basics > behavioural changes Recycling Use whatever recycling facilities are available for paper, glass, plastic, batteries, etc Meeting rooms Turn off the lights and projector when your meeting is over Personal appliances & comfort Work with your facility manager to optimize the heating and cooling and eliminate personal heaters Use common sense use thermostats or heater/air conditioner controls wisely to avoid the need to open windows 21

22 Fix the basics > behavioural changes Equipment startup Are there startup procedures to avoid creating demand peaks? Equipment shutdown Are there shutdown procedures for end of shift? 22

23 Energy Matters - practising what we preach 2006/2007 Energy Action was our own internal initiative to use the 1-4 steps to save energy Our target was 20% energy saving across heating, lighting etc within our offices, warehouses and factories in the UK. We saved 22% of our energy bill Energy Matters is the updated internal initiative using the 1-4 steps to reduce carbon emissions Our annual reduction target is 3.5% as an average across the sites. Our Energy Remote Monitoring feeds live information to our Energy Manager and Facility Management team 23

28 Automate How can energy efficiency be automated? Quick win energy efficiency Lighting control Motor control 28

29 Control Command helps you achieve quick win energy efficiencies.. Why? A recent BEAMA installation industry white paper calls for a focus on reducing energy consumption before increasing supply capacity. So simply SWITCH IT OFF when not required. Control command solutions are: Generally lower cost simple switching solutions Simply installed, operated and maintained For retrofit or new build applications Visible and tangible benefits 29

30 Add active efficiency - automate lighting For greatest efficiency, control lighting operation by: Time Schedule Occupancy control Ambient light level control The COCOM range is a menu of control products inc: Contactors Time switches Light sensitive switches Movement Detectors Presence detectors Time delay relays Impulse relays 30
