Tolworth Hospital

Overview

The South West London & St George’s Mental Health NHS Trust was formed in 1994 and has a long history of providing mental health services. The Trust provides a comprehensive mental health and social care services to the residents of Kingston, Richmond, Merton, Sutton and Wandsworth boroughs, as well as a number of specialist regional and national services.

The Problem

Patient care remains the Trust’s primary focus but it is also committed to improving sustainability within the organisation because of the longer term impact it has on the health and wellbeing of its servicer users, employees, visitors and the wider community.

In 2010 the Trust joined the 10:10 campaign to cut carbon emissions, pledging to cut its total emissions by at least 10% in one year.

Our Solution

A voltage logger was sent to Tolworth Hospital for one week, which recorded the voltage levels in the building. It was found that the average voltage at the site was 248 volts (18 volts higher than the nominal supply in the UK). After a survey of the site by a powerPerfector approved contractor, a powerPerfector unit was installed at Tolworth Hospital.

The Results

The Trust exceeded the 10% target, cutting its carbon emissions by 11%. The Trust’s Carbon Reduction Plan, developed with the Carbon Trust, has a carbon emissions reduction target of 25% by 2015 from the 2008 baseline. South West London & St. George’s Mental Health NHS Trust is well on course to meet this target.
