Case Study: HM Prison Swaleside

Case Study: HM Prison Swaleside

Carrying out an Energy Audit at a prison housing 1,000 category B prisoners is no easy task – but we succeeded. We also identified a possible 28% reduction in CO2e.

The Brief

HMP Swaleside is located on the Isle of Sheppey and is built on the site formerly occupied by the Eastchurch Aerodrome. The prison opened in 1988 and houses over 1,000 category B prisoners, with 460 places for lifers.

As part of a pilot programme for the South East prison network, HMP Swaleside wanted to demonstrate their commitment to energy management and its environmental impacts, as well as reducing their overheads and improving resource efficiency. To that end, we were asked for identify energy conservation measures to help reduce their 16GWh consumption – nearly 4,730 tCO2e.

Our Approach

We carried out an Energy Audit alongside the Works Department and the South East Energy Advisory Committee. The team also included mechanical, electrical, and building managers, as well as BMS contractors.

We coordinated our efforts and successfully identified a possible 28% reduction in CO2e, which amounted to a 27% reduction in cost at the time of writing. We also determined that HMP Swaleside could achieve Carbon Reduction Reduction Commitment and Climate Change Levy savings of £16,044 and £11,619 respectively.

Our Solution

HM Swaleside’s next steps are likely to include the installation of energy efficient lighting and improvements to their BMS, as well as commissioning an aM&T system.
