Article featuring Chauvin Arnoux PEL103:
In his summer statement (2020), Chancellor Rishi Sunak announced a billion-pound programme to help improve energy efficiency in schools, hospitals and other public buildings. Called ‘The Public Sector Decarbonisation Scheme’, the programme, which is part of UK’s efforts to reduce greenhouse gas emissions from the public sector by 50%, is expected to see substantial investments in energy efficiency and heating upgrades over the next year.
‘The Public Sector Decarbonisation Scheme’ is laudable in its objectives, as the world as a whole is dealing with an unprecedented ecological crisis. However, perhaps the first thing facilities managers should invest in when looking to improve energy efficiency is an instrument that allows them to accurately measure and record energy usage. Having an initial benchmark – before embarking on any changes and upgrades – is essential for measuring improvement and progress through time.
A portable energy logger (PEL) like the Chauvin Arnoux PEL103 is the ideal tool for accurately monitoring power consumption and much more, including harmonic levels, voltage imbalance and power factor. In addition, by using a PEL103 across entire buildings and recording the results over time, facilities managers will be able to gain detailed and revealing insights into what’s actually contributing to their energy bills.
A PEL103 can be installed quickly and easily in a distribution cabinet where it can, for example, monitor circuits for lighting, HVAC, display screens, computer systems and more. If it is to deliver its full range of benefits, the PEL should be set up to make recordings over time. A day is good, but a full week or even longer is likely to be even better, as interesting things often happen at weekends! For instance, according to a survey carried out by British Gas, up to 46% of the electrical energy used by SMEs was consumed outside normal business hours, so paying attention to those out-of-hours costs can yield big dividends.
In case you’re wondering how monitoring energy efficiency actually works out in practice, Peter Halloway, Regional Sales Manager at Chauvin Arnoux describes how a recent project at a secondary school in Kent provided some eye-opening findings...
