Sub-Metering, and your building

Become more energy efficient, how do you go about it?

Improve building performance

So, a business or organisation wants to become more energy efficient, how do you go about it?

The importance of evaluating energy use in a building actually led to the creation of BREEAM (Building Research Establishment Environmental Assessment Method). First published by the BRE in 1990, it is now the world’s longest established method for assessing, rating, & certifying the sustainability of new buildings.

To understand your buildings energy usage, data is essential. You would expect most commercial buildings to have a BMS, old or new; but unfortunately quite often older buildings only have stand alone meters installed or a metering network that has not been interfaced to the BMS. These meters require manual meter reading, ie someone having to check each meter in turn and manually record these values. Both costly and time consuming.

Simply, by replacing these stand alone meters with protocol dependent meters for example, M-Bus / ModBus / BACnetIP / BACnet MSTP, and installing an appropriate data collector, such as our SIP2 or SIP+ hardware, the meter values can be accurately and reliably be exported to the energy monitoring and billing platform for analytical / billing purposes, eg SIPinsight EBIS and SIPinsight Billing and, if required exported to the BMS for display.

Installing additional sub-metering is also an excellent investment and can provide extra information used to analyse where energy is being used.

Both our SIP2 and SIP+ hardware products allowing multiple network connections and reporting to SIPinsight EBIS and SIPinsight Billing or suitable third party monitoring software, the BMS can be left to controlling the the building environment.

You can then with or without our help monitor and target where energy is being wasted.
