The Problem

The specification called for control for individual room energy monitoring

The Solution

Prefect irus room controllers and pulse meter nodes


The Wellcome Trust appointed Balfour Beatty as their delivery partner for a new £12 million student accommodation block at 200 Euston Road, London. Construction of the seven-storey project at Bentley House was completed in the summer of 2014. The scheme involved demolition of part of the existing building behind a retained façade and construction of a high end 171-bed accommodation block and on completion the building was certified with a BREEAM ‘Very Good’ rating. Prefect Controls was asked to provide an integrated room heating and lighting control system for all 171 apartments. With special emphasis on door entry control and window open deactivation so heating could not be left on when windows were open. Utilizing the “Prefect irus” central control system the Prefect team set about devising the control strategy that would provide the student guest with the ability to control their environment whilst the system works behind the scenes to control the use of energy. Working alongside the door lock manufacturer the Prefect team enabled the door lock proximity card to trigger the rooms clever thermostat into heating comfort mode whilst also bringing power onto the lighting and non-essential circuits. Information about room activation together with room temperature were then sent back to the central control via a web browser where the Wellcome Trust management team are able to view status and make adjustments to individual room set points. The irus systems ability to integrate with third party equipment provided the client with a secondary use for the system, to read and display the room metering across all 171 apartments. The Wellcome Trust are now looking at other projects where the Prefect Irus system can be used.
