The day the clocks go
back truly signals a new season – colder days and darker nights abound; but
it’s also a good time to undertake your next Building
Energy Management System (BEMS) audit.
This year, the UK will turn back one hour on Sunday 28th October (so
don’t say we didn’t warn you…now you can make the most of the extra hour’s
When the clocks go back in the calendar, they must also be
updated on your BEMS. If they’re not updated then your BEMS settings will be
one hour out for six whole months, and that can have a significant impact on
building operations and costs of running plant unnecessarily.
Put simply, if your BEMS is unable to react quickly to
create optimal comfort conditions based on criteria such as levels of
occupation, ambient temperature and patterns of usage, it will fail to serve
its intended purpose.
Autumn is the perfect time to consider a BEMS audit, which
will not only optimise and reset time clocks and setpoints, but also
drill down to the finer details and provide guidance about implementing
appropriate technologies like variable speed drives
(VSDs) . It is often the case that adjustments can be made to the BEMS
during the audit visit itself that will deliver immediate savings, while
component parts can also be checked to make sure they are working correctly.
People often forget that when a BEMS is first commissioned
it is configured around an existing or even an expected building layout and
occupancy patterns. Throughout the year these can change and
incorrectly configured time clocks, setpoints, new layouts, repartitioning, or
the addition/relocation of equipment can have a detrimental effect on energy
Where an audit really comes into its own though is in its
ability to help construct an energy
management plan that features a prioritised summary of
activities that should be carried out in the short, medium and long-terms. It
will help break the project down
into ‘bite sized chunks’ that initially focus on gathering
utilities based data, identifying wastage, and then prioritising ways to reduce
overall energy consumption.
We have also launched a BEMS Risk Assessment Report this
month, giving you a succinct overview of the BEMS asset resilience across your
estate; identifying risk factors and recommending how best to tackle them –
either immediately or over time.
Remember, a BEMS should always be considered a work in
progress and maintaining it on a regular basis and carrying out a scheduled
audit will help maximise any energy and cost saving opportunities provided by
