The Barbican


The Barbican is Europe’s largest multi-arts and conference venue, presenting a diverse range of art, music, theatre, dance, film and creative learning events, it is also the home of the London Symphony Orchestra.

The Problem

With such a packed schedule of events, making infrastructure improvements at the Barbican can be a logistical challenge. Typical of most large sites, the Barbican has a number of individual electrical supplies, more than 25 in total. These are spread across the centre.

Our Solution

Following a survey of the site by an electrical engineer and with the help of the Barbican team we identified a suitable area in which to trial the technology. Six supplies entered the building near to the library, a small portion of which was reallocated to house the six VPO® units required.

As with all powerPerfector installations, to minimise disruption, all site works were completed prior to the shutdown. This includes cabling, trunking and any changes needed to the existing switchgear.

The six units were then delivered to site and energised in three tranches over a ten-day period. This allowed the installation team to systematically ensure that all electrical equipment on site was functioning effectively at an optimised voltage.

The Results

Three months after installation, EEVS Insight began to calculate the savings. Using the International Performance Measurement and Verification Protocol (IPMVP) the savings for the project as a whole were calculated to be 7.45%. This represents an annual saving of £23,404.

The saving was just under that guaranteed by powerPerfector of 7.49%. Further investigation revealed that since the tender was submitted, a lighting refurbishments had taken place which impacted on the savings.

The Overview

  • 7.45% kWh Saved
  • 152,800 CO2kg Saved
  • £23,400 Saved

“We were impressed with the professionalism of the powerPerfector installation team, which meant the installations were completed without incident. It was one of the easiest energy efficiency installations we have completed to date.”

“The savings the units have achieved make this an attractive energy efficiency measure. We are working with powerPerfector to identify other opportunities across the Barbican estate.”
