UNIVERSITY OF BRISTOL – A LEARNED DECISION IN ENERGY SAVINGS

Our latest case study for the education sector demonstrates the ability of Powerstar’s patented technology to achieve savings in a wide range of industries through the installation of a Powerstar LITE and Powerstar MAX retrofit at the prestigious University of Bristol.

Ranked within the top 50 universities in the world in the QS World University Rankings 2018, it is no surprise that the University of Bristol is one of the UK’s most popular and successful universities. It is at the cutting edge of global research, with innovations made in areas ranging from cot death prevention to nanotechnology.

The University of Bristol’s passion for research and innovation means sustainability is a large part of everything they do, including in their research, buildings, and student experience. It was due to this sustainability focused ethos that the university was searching for ways to reduce its energy consumption, in order to minimise its energy consumption and as a result reduce CO2 emissions and electricity costs.

The university explored the potential impact on savings that implementing voltage optimisation technology could make, and, following their research, made contact with us as a global market leader in voltage optimisation solutions.

After a thorough site survey and analysis of the university’s voltage profile by the Powerstar team, we concluded that the university was a valid candidate to achieve significant benefits from the installation of voltage optimisation technology due to the varying range of equipment and activities on-site. Through the survey, we found that the voltage profile of several areas across the university was higher than required for the equipment being utilised.

To resolve this overvoltage, we recommended the installation of 22 Powerstar LITE systems – a fixed low voltage optimisation solution that reduces the incoming voltage by a set, pre-defined amount.

All of the systems were supplied as fully bespoke, concept to completion solutions defined by the requirements of each location, with the 22 Powerstar LITE solutions ranging from 750kVA to 1250kVA. It was critical that, given the sensitive research processes undertaken by the university, the delivery of the voltage optimisation solutions was as un-invasive as possible, and we ensured minimal disruption to processes due to our extensive experience working with sensitive operational processes.

Analysis of the Powerstar LITE’s post-installation later showed an average consumption saving of 5.2% was achieved by the University of Bristol.

Several years after the installation of the fixed voltage optimisation solutions, Powerstar returned to the university and undertook further evaluation of the site’s saving potential following the university’s natural facility upgrades. This revealed that 8 of the Powerstar solutions already in place could benefit from a retrofit upgrade to a Powerstar MAX solution – an electronic-dynamic voltage optimisation solution – to accommodate the found fluctuations in the supply and generate additional cost and CO2 emission reductions. After retrofitting of the Powerstar MAX solutions, with the same stringent focus of minimal disruption to processes, the University of Bristol achieved an additional average consumption saving of 4.8% from the upgrade systems alone.

We are proud to help such a prestigious educational centre achieve savings in energy consumption and carbon emissions and look forward to seeing further innovations cultivated by the sustainable ethos of the university, an ethos and commitment to research shared by ourselves at Powerstar.
