BeMS 101 – Internal Or External Management?

Should you pay for someone else to monitor and manage your energy systems to save you money?

Ok, let’s start with a simple question – Do you feel that you have the knowledge to tune a car so that it runs smoothly in all situations. If you don’t have this type of knowledge and ability or experience to analyse, then I believe you will struggle with any medium to large heating system. It’s just not the same as your house heating system where you are using one or two rooms in a house and you decide it’s a bit on the cold side, so you switch up the thermostat. Modern heating systems which are managed through a Building Energy Management System can be made up of multiple systems which are monitoring and managing the following elements:-

– The boiler

– Individual heating pumps – there may be many for different sections / buildings

– Multiple thermostats for different areas of the buildings

– Multiple motion sensors for different areas of the buildings

– Outside thermometers.

– Air conditioning both for comfort and cold storage.

And this is just management of the heating system. A complex BeMS can manage Heating Ventilation and Air Con, domestic hot water, electrical supply and distribution, energy consumption, lift systems, and more. So unless you have a very simple system I would advise you to have an ongoing maintenance contract to make sure that your BeMS is operating at optimal levels throughout the year. This means you will #SaveEnergySaveMoney each and every day.

But that’s enough info for today.
