Energy leaks are economically and environmentally costly. To help businesses maximise energy efficiency, reduce costs and comply with environmental government policies, Chauvin Arnoux has compiled the following white paper: Sound Advice on Saving Energy: Outlining the Path to Sustainability and Energy Efficiency.
The Carbon Trust estimates that by fixing energy leaks businesses can make savings of approximately 20%. Energy efficiency can also help to secure lucrative contracts: increasing focus on sustainability and climate change means that it is becoming more and more common for tenders to request details of environmental policies and evidence of their effectiveness. Failure to produce these policies can result in tender disqualification and loss of business.
Additionally, the Streamlined Energy and Carbon Reporting policy means that approximately 11 900 companies incorporated within the UK will be required to disclose their energy and carbon emissions. This government policy is designed to ensure that businesses contribute to achieving 2050 targets of ending the UK’s contribution to global warming.
Chauvin Arnoux’s white paper details how businesses can increase energy efficiency and reduce costs and emissions by making changes to workplace environments (e.g. lighting, heating, and use of electric motors) and improving electrical supply (e.g. power factor, phase imbalance, and harmonics).
|Corrective Measure||Potential Saving|
|Effective energy efficiency measures||20%|
|Average SME out-of-hours usage||46%|
|Occupancy sensor-controlled lighting||30%|
|Automatic daylight adjustment for lighting||40%|
|LED lighting in place of incandescent||80%|
|Power factor correction||30%|
It also highlights the importance of implementing and maintaining an energy management system as required by the ISO 50001 standard and International Performance Measurement and Verification Protocol (IPMVP). Chauvin Arnoux’s white paper details the methodology informing IPMVP’s ‘Measurement and Verification Plan’ and emphasises that accurate, reliable and comprehensive measurements are essential for locating energy leaks, identifying the changes necessary to improve energy efficiency, and monitoring the success of these implementations in the short-term and long-term.
Chauvin Arnoux advises that this will involve investment in a range of test instruments such as light meters, thermo-anemometers, and portable power and energy loggers such as the PEL 103. However, initial investment costs will be quickly recuperated by energy savings.
Portable power and energy loggers (PELs) can be used to conduct initial energy audits to establish a baseline and identify areas most in need of improvement. Subsequent to this, PELs can be used to monitor the success of any changes in the short and long term.
PELs are compact, lightweight instruments that can be easily integrated into distribution panels. Their comprehensive measurement capabilities and large memories mean that they can record data for key electrical parameters such as three-phase current, power factor, and harmonic levels. Depending on the user’s chosen model, data can be retrieved locally or remotely via USB, Ethernet or Bluetooth.
