Introduction

Johnson & Johnson (J&J) Vision Care was established in Limerick in 1996 and is one of several J&J companies operating in Ireland, otherwise known as Campus Ireland, employing approximately 2,500 workers in total. J&J Vision Care manufactures and markets the ACUVUE® range of soft disposable contact lenses.

Approach to energy efficiency

The J&J Vision Care energy team was formed in 2011 with a mandate to improve the site's energy performance and in turn reduce site energy related CO2 emissions.

In the last five years the energy team has supervised and led the investment of over $25M in energy efficiency projects. The team leveraged the global J&J CO2 reduction fund to implement these projects. This is one of the largest drawdowns from the fund within the group and it has helped to fund

  • onsite generation using combined cycle cooling and power generation (CCP)
  • an extensive 1MW geothermal cooling loop  
  • the installation a 500kW heat pump
  • a large scale HVAC free cooling project, and most recently  
  • the installation of a 3MW wind turbine for onsite electricity generation.

Activity and savings achieved

One of the projects alone, the geothermal cooling loop project, resulted in providing over 1GWh free cooling per annum of energy which does not need to be supplied by the site chilled water system and constitutes a saving of over 435 tonnes of CO2. The combined CO2 emissions avoided as a result of the installation of the full suite of projects is over 20,500 tonnes since 2011. This equates to an energy reduction per lens of 16% over the last five years which is an achievement that is appreciated by their customers who value their strong commitment to sustainability.

These CO2 related site savings are significant in the context of the J&J global carbon reduction targets - 20% of 2011 consumption by 2020 and 80% by 2050.

Conclusion and future plans

Buoyed by this success, J&J Vision Care appointed a full-time energy lead in early 2015. Since then, the energy lead has structured the energy management programme in line with the J&J Campus wide ISO50001 energy management programme, culminating in the site’s inclusion in the group certification to ISO50001 in late 2015. This work has resulted in the formation of significant energy user focused energy teams, engagement from the production floor to instil energy as part of their standard operating principals and engagement from the wider community via a site-wide ‘energy awareness’ campaign.

The site energy team has secured additional funding in order to deliver further projects which are targeting a CO2 saving of 8000 tonnes of CO2 over the next 12 months.
