West Middlesex University Hospital manage social, ethical and environmental issues in a way that grows value and helps the Trust, their patients and visitors be more sustainable.

The hospital regards sustainability as a key aspect of their operations and participates in a number of sustainability projects which help reduce their impact on the environment.

As an acute hospital based in Isleworth, West London, West Middlesex University Hospital serve a local population of around 400,000 and have over 400 beds. Employing around 1,800 people, the hospital’s sustainability practices need to be efficient, secure and reliable as they potentially impact a high number of people.

West Middlesex has an impressive record: they perform well in comparative assessments of clinical performance and has a rolling programme of investment in the latest equipment and technology.

The Challenge

With a highly emphasised commitment to teaching, West Middlesex University benefits from the latest equipment and technology.

The hospital also recognise that part of the strength of the Trust is the dedication and commitment shown by everyone who works there.

With a commitment to lessening its impact on the environment, the hospital is focused to ensure only the most efficient technologies are implemented on site. Hospital management are also keen to ensure that all technologies honour their dedication to not only achieving sustainability targets but also uphold social and ethical policies.

The Solution

Powerstar, the flagship product in EMSc (UK) Ltd’s product catalogue and has a track record of electricity savings, carbon reduction and dependability within healthcare estates.

West Middlesex University Hospital saw the potential of implementing Powerstar voltage optimisation, and with the reassurance of guaranteed energy consumption savings made the decision to implement the system on site.

The protection and prolonging of hospital equipment through reduced voltage provided an additional boost to the hospital, in addition to the headline savings.

The Business Benefits

The project of installing Powerstar at West Middlesex University hospital was carried out in conjunction with Bouygues UK, construction, development and regeneration project managers.

West Middlesex University Hospital have reduced their energy consumption by 8.4% on the two transformers fitted with the Powerstar voltage optimisation system. The energy saving equates to 163.6 tonnes of saved carbon dioxide.

These savings were delivered on a modern purpose built site which has BMS, VSD’s and many other energy saving devices installed through out.

EMSc’s commitment to manufacturing Powerstar fully in the UK, provided Middlesex Teaching Hospital not only with the best possible solution, but also one that was manufactured locally and not transported across the globe from China or Japan, itself an important factor in reducing the global carbon footprint.

Savings Analysis

Figure 1: Pre install and post install actual consumption and regression model forecast without Powerstar

Figure 1 above shows the actual consumption pre install (red) and post install (green) and the model of what consumption would have been at baseline efficiencies.

The difference between the model and post install actual consumption is used to calculate the savings being made after Powerstar was installed.
