Switching to more energy efficient lighting in a renal unit

Key learning point 

Light fitting change resulted in improved the energy efficiency leading to carbon reduction whilst improving illumination and saving finances.

Setting/Patient Group: Renal Unit (offices and wards)

Issue to be addressed:

Energy is responsible for approximate 10% of the carbon footprint of the NHS.

The unit invested in a greener energy initiative using a British Journal of Renal Medicine (BJRM) Innovation in Renal Medicine Award 2011 prize (£5,000).

Fluorescent light fittings in the renal unit were of a 'T8' type, whose energy consumption was double that of newer 'T5' light fittings and not effective enough produce sufficient illumination for technical staff.

Intervention:

  1. Site survey of the renal unit and staff consultation to identify areas of intervention
  2. Switch to install 'T5' light fittings (changing 85 fittings across renal offices and wards)

Outcome:

Clinical

  • Improved illumination for technical staff

Social

  • Happier staff due to increased levels of lighting.
  • An improved working environment

Environmental

  • Estimated annual carbon savings of 2.3 tonnes CO2e/yr, projected to 11.5 tonnes of CO2e over 5 years.
  • Improvement in measured lighting levels and reduced maintenance costs as the new light fittings have a longer life span
  • Contributes to the achievement of the Trust's sustainable development goals

Economic

  • Estimated annual savings £612/yr.
