A fully optimised Building Energy Management System (BEMS) means considerable energy savings, lower CO2 emissions and perfect comfort conditions for occupants. I’m Pradeep Singh, Area Sales Manager, South West and Midlands region at Trend and in this blog, I’ll explain why April is a good time to give your BEMS a spring clean by using control check reports (CCRs).
With any luck, the cold winter weather will now be a thing of the past and I’m sure I’m not alone in hoping for a hot and sunny summer. With the end of March heralding British Summer Time (BST), a BEMS must be adjusted to account for the clocks going forward. April is, therefore, a great time to spring clean a BEMS by checking all time zones and setpoints, as it sits between the busy heating and cooling periods.
Research conducted by Trend through its auditing service found that an alarming 39 per cent of energy usage is wasted within the workplace. Incorrect operating time zones and setpoints directly influence a site’s energy consumption and are two of the biggest contributing factors to wastage. The good news, however, is that they are amongst the easiest problems to address and doing so can lead to instant savings. I believe that the best way to deal with this issue is through the use of CCRs.
A BEMS should be seen as both a control system and a reporting tool and a CCR can be produced to maintain parameters across a single site or estate in a graphical and easy to read format. Quite simply, it does all the hard work for you and displays time zone information in a way that quickly identifies where there is an error in occupation times and setpoints
meaning that fast remedial action can be taken.
In terms of best practice, I would also advise producing a CCR on a monthly basis so that it becomes part of a routine that keeps tight control over a site’s energy usage and helps to keep occupants happy. As the data is pulled straight out of the BEMS, there is other information that can be overlaid on to this report including energy consumption, space temperatures, footfall etc. In fact, any information that is recorded by a BEMS can be utilised in this way, helping to maximise return on investment.
A BEMS should never be considered a fit and forget technology, as getting the best out of it requires an ongoing optimisation programme that quickly and easily incorporates the latest technologies, reconfigures time zones and setpoints and takes into account changes to a building’s layout and occupancy patterns. So, a CCR that highlights the current settings of a BEMS in an easy to read and interpret format can be a huge benefit and provide the basis of a spring clean that will make sure that a BEMS is running properly and providing the comfort levels required.
