In a demonstration project, Viegand Maagøe scrutinized the energy used at Eli Lilly’s new cancer drug manufacturing plant in Cork, Ireland. We were able to reduce the carbon footprint of the new manufacturing plant by more than 30 %.

Client: Eli Lilly

The task
In the 1990s, energy efficient design of manufacturing plants was a successful focus area in Denmark. The Sustainable Energy Authority of Ireland adopted the Danish concept in 2007 and has supported several large pilot projects using Viegand Maagøe as the consultant. The first project was carried out at Eli Lilly’s new manufacturing plant in 2007–2010.

How we carried out the task
Viegand Maagøe was able to help Eli Lilly by scrutinizing its energy requirements from the early planning stages through to the completion of the plant. Our work included some of the following:

  • mapping CO2 emissions and energy consumption of the basic design;
  • evaluating and prioritizing focus areas;
  • challenging the design requirements, in particular for HVAC (heating, ventilation and air conditioning) and the CIP system (flushing of pipework, etc.);
  • detailed optimization of the HVAC, CIP and refrigeration installations;
  • developing the for the utility structure, including heat recovery; and
  • reporting and publicizing the results at conferences, etc.

The result
We were able to identify large potential savings in the planned design of the plant – nearly 70 % of the expected energy consumption – about half of which was achieved during the course of the project. Eli Lilley subsequently revised many of its internal company requirements, with the result that it can plan future manufacturing plants on a much more energy efficient basis.

The project was awarded a 1st place as the best demonstration project at the Sustainable Energy Authority of Ireland’s Energy Show 2010.
