Energy-saving and compliance reporting

PrefectIrus is packed with features that distinguish it from simple thermostats or complex building energy-management systems

Designed specifically for university accommodation, PrefectIrus is unique in its focus on maintaining comfortable environments while ensuring energy is only used when it is needed.

The nodes, located throughout accommodation blocks, cleverly ‘learn’ the environmental conditions for each individual room – heat required, time to reach temperature, dissipation rates, etc. There are also sensors and evidence gathering for lighting, humidity and decibel levels with an optional extra of a CO2 detection module.

PIRs recognise when rooms are empty and automatically reduce input – in the same way, open-window technology cuts heat until the window has been closed.

The software then balances comfort and energy-use for the benefit of students and energy managers.


Data from nodes is transmitted to the central controller via the existing electrical wiring within the building. Managers of accommodation, energy or compliance are able to monitor information from anywhere with internet connectivity via the easy-to-use web-based portal and, on screen in real time, control temperatures and monitor student wellbeing throughout their estate.

By monitoring electric tariffs, Irus is able to switch hot water and heating off to coincide with Triad warnings, ensuring energy is only used when rates are economic.

Using Mains Borne Signalling means the system is quick and cost-effective to install, with little disruption to infrastructure. Better still, it does not need rooms to be unoccupied, so installation can be carried out at any time of the year, not just during holiday periods.

The energy-saving benefits of PrefectIrus are complemented by maintenance and compliance attributes, including the detection of faulty or failing third-party components and reporting to satisfy water-safety plans. All this ensures students can enjoy an environment conducive to study.
