    Im in the hospitality business and wanted to use six sigma to reduce energy consumption. Im stuck in how to define the process of energy consumption. I understand that energy consumption is related to amount of equipment being used and their efficiency.
    I would appreciate if I could get some clarity on this.

    I am not sure I fully understand your question. Energy consumption is a great project. It can very simple to very difficult depending upon your situation. Below is a suggestion of how to start.

    All power consumption is not equal. You will want to focus on the biggest opportunity.

    Define the Biggest opportunity:
    1: Measure the consumption rate (KW/Hr) or some other meaningful rate measurement.
    2: Create a Pareto chart. This will let you quickly see which item(s) is consuming the most energy.

    Develop Potential Solution:
    This is where your knowledge of your business must be used. For simple examples, it may be as simple as reducing the use of high energy consumption equipment. This is not likely a viable option as it requires either investment in new equipment or reducing your service level. Some communities give you breaks on price if you consume at night vs. peak hours. Again, I doubt this is effective because you must provide service when it is requested.

    Ideas to also consider:
    1: Evaluate your service. Do other methods exist to deliver the same service? Try to creatively describe 7 ways to do the same function in a different way.

    2: Break your service into segments. Is your equipment required to run during every segment. (This is also a good way to consider as you are measuring the problem. Rather than measuring the energy consumption of each device, measure the total consumption of each segment.)

    3: Test your high energy items to determine if you can change the setting to consume less power and still deliver the same result.



    I would add to Shelby’s advice, write a clear and specific problem/opportunity statement. This is often the hardest part of getting started. Ideally it should be just one or two sentences. I like to say it should “SPARC”. Specific – narrow it down rather than try to “boil the ocean”. Proven – it’s a real problem, supported by data, rather than assumed. Assessable – The extent and impact of the problem has been measured, or at least you will be able to measure it. Relevant – It matters regarding goals, objectives, and customer needs. Controllable – You can actually do something about it. The project will fail if the cause of the problem is outside your sphere of control. In this case you should revise the problem statement. A good problem statement should light a spark — We need to put out this fire.

    In My Point of View Energy consumption is converted in to Money that is Units per Rate
    Business Metric is Reduce Units per rate
    Primary Metric is Reduce the Energy consumption per Visitors
    Consequence Metric is Maintain the Customer Compliant
    Finance Metric is in Value

    In Measure phase track the Data area or location wise through the 80-20 rule. Using this 80% contribution we identify that is Project scope was identified.

    Process Flow diagram, I/O Sheet, Fish Bone diagram is useful for collecting ideas / Views from the Team
