Monitoring energy use

SPONSORED: An accurate current meter in every bedroom and hot water tank

Prefect Controls have introduced a new feature for their PrefectIrus product – the integration of an accurate current meter that monitors energy use in each room throughout multi-occupancy buildings such as
student accommodation.

Until now, managers have calculated energy use based on power rating multiplied by length of time a device is estimated to be active. However, fluctuating voltage and imprecise predictions of ‘on-times’ can make these estimates wildly inaccurate.

The new PU3 from Prefect comes with iACM (Integrated Accurate Current Metering) as standard, logging the current only when a heater is operational. This data is then transmitted via the building’s wiring system to the central controller where it is recalled for estimation of seasonal energy usage.

As well as monitoring heaters in bedrooms, the feature notifies managers if there is a problem with hot water tanks. Usually a problem is only evident when both elements fail and water isn’t being heated. 

With accurate metering, if one element fails, the drop in current immediately identifies the problem – meaning efficiency can be restored.

Glen Golding, Prefect Controls MD, said: “This development means accurate usage can be calculated so that better purchasing of energy will lead to greater savings for organisations providing multi-occupancy accommodation.”

PrefectIrus is currently in more than 20,000 bedrooms and continuous development makes it an invaluable product to ensure efficient use of energy across Britain’s university accommodation estate. For further information, contact Glen Golding on 01787 320 604.
