What Sub-Metering did for Nissan in Tennessee

When Nissan built its motor manufacturing plant in Smyrna 30 years ago, the 5.9 million square-foot factory employing over 8,000 people was state of art. After the 2005 hurricane season sky-rocketed energy prices, the energy team looked beyond efficient lighting at the more important aspect of utility usage in the plant itself. Let’s examine how they went about sub-metering and what it gained for them.

The Nissan energy team faced three challenges as they began their study. They had a rudimentary high-level data collection system (NEMAC) that was so primitive they had to transfer the data to spread-sheets to analyse it. To compound this, the engineering staff were focused on the priority of getting cars faster through the line. Finally, they faced the daunting task of making modifications to reticulation systems without affecting manufacturing throughput. But where to start?

The energy team chose the route of collaboration with assembly and maintenance people as they began the initial phase of tracking down existing meters and detecting gaps. They installed most additional equipment during normal service outages. Exceptions were treated as minor jobs to be done when convenient. Their next step was to connect the additional meters to their ageing NEMAC, and learn how to use it properly for the first time.

Although this was a cranky solution, it had the advantage of not calling for additional funding which would have caused delays. However operations personnel were concerned that energy-saving shutdowns between shifts and over weekends could cause false starts. ?We’ve already squeezed the lemon dry,? they seemed to say. ?What makes you think there?s more to come??

The energy team had a lucky break when they stumbled into an opportunity to prove their point early into implementation. They spotted a four-hourly power consumption spike they knew was worth examining. They traced this to an air dryer that was set to cyclical operation because it lacked a dew-point sensor. The company recovered the $1,500 this cost to fix, in an amazing 6 weeks.

Suitably encouraged and now supported by the operating and maintenance departments, the Smyrna energy team expanded their project to empower operating staff to adjust production schedules to optimise energy use, and maintenance staff to detect machines that were running without output value. The ongoing savings are significant and levels of shop floor staff motivation are higher.

Let’s leave the final word to the energy team facilitator who says, ?The only disadvantage of sub-metering is that now we can’t imagine doing without it.?

How Sustainable is Suez Environment

French-based Suez Environment works in the water and waste-management environment, with specific reference to water production, treatment, & pollution disposal, and waste treatment, recycling, incineration and site desensitisation. Its more than 65,000 employees distributed worldwide have participated in flagship projects like Renault’s goal of 95% reclamation of vehicle parts, and Lyonnaise des Eaux?s saving of 12 million cubic meters of water in a single year.

Suez Environment claims to have consistently increased the recovery rate of treated waste, decreased direct and indirect greenhouse gas emissions, and made significant inroads into the production of sustainable energy on behalf of its clients. But then surely that’s Suez Environment’s business, and with over 65,000 employees we are entitled to expect this. Given that there have been persistent allegations of privatised water distribution bumping prices up to the detriment of the poor, how effective is Suez Environment at practising what it preaches back home?

GDF Suez is its largest shareholder and includes it under its environmental and societal responsibility umbrella. This makes environmental performance an overarching goal alongside management systems, health and safety, risk and procurement, and ethics. Its environmental ambitions spin out into the following strategies:

  • Understand the interactions between our activities and the environment
  • Open dialogue with stakeholders and foster partnerships with them
  • Set quantitative and qualitative targets at all levels of the organisation
  • Achieve optimum balance between financial and environmental challenges
  • Be proactive; anticipate impacts on the environment and plan for them
  • Increase employee awareness through interactive training and education
  • Be constantly innovative; share successes within the organisation
  • Monitor progress continuously and publish measured results achieved.

These goals direct the Suez Environment management team?s attention towards optimising performance in key areas like greenhouse gases, energy management, renewable energy, biodiversity, responsible water management, pollution prevention and health and safety considerations.

Among numerous other examples, its waste incineration programs convert hazardous and conventional waste into heat used to generate electricity without requiring virgin carbon products. Elsewhere, the same energy warms market-gardening tunnels and work places on winter days.

Suez Environment uses sophisticated energy management software to analyse information that’s transmitted by data logging devices online. ecoVaro provides a similar service in the cloud. ecoVaro adapts to your requirements providing fresh insights to your business.

Directions Hadoop is Moving In

Hadoop is a data system so big it is like a virtual jumbo where your PC is a flea. One of the developers named it after his kid?s toy elephant so there is no complicated acronym to stumble over. The system is actually conceptually simple. It has loads of storage capacity and an unusual way of processing data. It does not wait for big files to report in to its software. Instead, it takes the processing system to the data.

The next question is what to do with Hadoop. Perhaps the question would be better expressed as, what can we do with a wonderful opportunity that we could not do before. Certainly, Hadoop is not for storing videos when your laptop starts complaining. The interfaces are clumsy and Hadoop belongs in the realm of large organisations that have the money. Here are two examples to illustrate the point.

Hadoop in Healthcare

In the U.S., healthcare generates more than 150 gigabytes of data annually. Within this data there are important clues that online training provider DeZyre believes could lead to these solutions:

  • Personalised cancer treatments that relate to how individual genomes cause the disease to mutate uniquely
  • Intelligent online analysis of life signs (blood pressure, heart beat, breathing) in remote children?s hospitals treating multiple victims of catastrophes
  • Mining of patient information from health records, financial status and payroll data to understand how these variables impact on patient health
  • Understanding trends in healthcare claims to empower hospitals and health insurers to increase their competitive advantages.
  • New ways to prevent health insurance fraud by correlating it with claims histories, attorney costs and call centre notes.

Hadoop in Retail

The retail industry also generates a vast amount of data, due to consumer volumes and multiple touch points in the delivery funnel. Skillspeed business trainers report the following emerging trends:

  • Tracing individual consumers along the marketing trail to determine individual patterns for different demographics and understand consumers better.
  • Obtaining access to aggregated consumer feedback regarding advertising campaigns, product launches, competitor tactics and so on.
  • Staying with individual consumers as they move through retail outlets and personalising their experience by delivering contextual messages.
  • Understanding the routes that virtual shoppers follow, and adding handy popups with useful hints and tips to encourage them on.
  • Detecting trends in consumer preferences in order to forecast next season sales and stock up or down accordingly.

Where to From Here?

Big data mining is akin to deep space research in that we are exploring fresh frontiers and discovering new worlds of information. The future is as broad as our imagination.?

UK Hauliers Pull Together on ESOS

ESOS is what UK business needed, to encourage it to become more responsible for the environmental consequences of making money. Government has met with industry leaders to hammer out the finer details. Now there are heartening signs of intra-industry collaboration, for the example the FTA approach we discuss here.

The Freight Transport Association (FTA) is one of the UK?s biggest trade associations, and exists to represent the interests of companies moving goods by air, rail, sea and road. It is their representative at national, European and local level that advises them on legal compliance. In February 2015, it announced plans to help the industry comply with ESOS too.

The association has been active since the announcement of the UK?s Energy Saving Opportunity Scheme. It has engaged with government and membership through the portal of its Logistics Carbon Reduction Scheme (LCRS). The Environment Agency has singled this out as a benchmark other industries could follow.

FTA general manager for consultancy and tendering Karen Packham recently said, ?With our highly experienced and fully qualified team of transport auditors ?the FTA is best placed to offer practical advice and is able to provide specialist audits to ensure members are fully compliant ? and will gain all the benefits that the scheme has to offer.?

These co-audits with Environment Agency specialists advising, will focus on the full range of operational and supporting activities, and ensure that all haulage companies with over 250 employees do the following:

  • Assess energy use across their full spread of buildings, transport media and industrial activity
  • Examine energy-intensive pressure points and identify savings opportunities that provide financial benefit
  • Nominate an ESOS person to conduct future audits, or oversee and approve them independently
  • Report to the Environment Agency as scheme administrator per statutory intervals

Ecovaro has energy management software that turns metrics into high-level information that busy people understand. Give us a call if you are puzzling how best to present your data. We believe two heads can achieve so much more together.
