Unformatted text preview: urthermore, anecdotal evidence from limited observation at the IADC indicates that many pieces of
process equipment are significantly oversized relative to current levels of customer demand, product
mix and operational flow. Additional study is needed to estimate the potential reductions in process
energy using this approach, and given the lack of focus in this area, the 11% figure from support
systems is likely a lower bound at least for the IADC. Chapter 6 Discussion
6.1 Hypothesis review A review of the hypotheses of Chapter 3 indicates that all three lean approaches can be used to
increase energy efficiency of manufacturing processes without major impact on production schedules.
Moreover, two of the three (measuring energy usage of individual equipment as part of team-based
continuous improvement projects and using real-time data feedback to operators) do not require
major capital allocations but instead are achieved by behavior and operational changes with existing
