WEMS wireless energy management slashes electricity costs in Dubai

A WEMS wireless energy-management system is already realising reductions in energy consumption of up to 54% in 31 laboratories and public-health buildings belonging to Dubai’s Ministry of Environment & Water (MoEW). Installed by TSM, the projects are the first of three planned phases which cover multiple sites across the country.

Faced with increases to the underlying cost of electricity, the single biggest utility cost in typical Middle East buildings), a complete WEMS solution was installed into buildings specified by MoEW.

Before the WEMS system was installed, there was a lack of remote visibility of the plant operating in the buildings, which meant that the MoEW was running blind and unable to see how or whether any energy-saving schemes were making an impact.

However, the main motivator was the reliance on manual intervention and good housekeeping to ensure lighting was switched off at night and air conditioning disabled. These two electrical loads make up most of the electricity bill.

The WEMS MX range offered a simplified engineering process and reduced installation time by around 30% — enabling TSM to put forward a much stronger business case than with a hard-wired solution.

Energy savings in the first three months after installation ranged from 48% for the laboratory building in Ras al-Khaimah, 39% at buildings in Al Fujairah, 38% in Al Dhaid and 29% at Sharjah.

In the first month a 54% reduction in energy use was achieved at Ras al-Khaimah.
