Office Building MIOC

The Manchester International Office Centre, is a familiar sight for all South Manchester commuters heading to the airport. Its total 100,000 sq ft of space is divided into suites from 400 to 16,000 sq. ft.


The electrical infrastructure at MIOC is a single transformer supply into the building. The landlord sub-meters so each tenant only pays for the energy they use. Locating and installing the Voltage Optimiser in the required position was a significant challenge but it was completed with minimum disruption. Incoming Grid voltage was consistently high, at 246v average throughout the building. As a result it was possible to set the Optimiser to reduce voltage by the maximum 10% resulting in a 16.2% Kwh reduction in consumption directly from the Optimiser simply doing its job.
