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.?

Article 8 of the EU Energy Efficiency Directive ? Orientation

Following in-depth discussion of the UK?s ESOS response, we decided to backtrack to the source, especially since every EU member is facing similar challenges. The core purpose of the directive is to place a pair of obligations on member states. These are

  1. To promote the availability of energy audits among final customers in all sectors, and;
  2. To ensure that enterprises that are not SMEs carry out energy audits at least every four years.

Given the ability for business to look twice at every piece of legislation it considers unproductive, the Brussels legislators took care to define what constitutes an enterprise larger than an SME.

Definition of a Large Undertaking

A large undertaking meets one or both of the following conditions:

  1. It employs 250 or more people
  2. Its annual turnover is more than ?50 million and its balance sheet total exceeds ?43 million

Rules for Energy Audits

If accredited / qualified in-house specialists are unavailable then independent experts should supervise audits. The talent shortage seems common to many EU businesses. In hindsight, the Union could have ramped up slower, especially since the first compliance date of 5 December 2015 does not leave much swing room.

ecoVaro doubts there was a viable alternative, given the urgent imperative to beat back the scourge of carbon that is threatening the viability of our planet. The legislators must have been of a similar mind when laying down the guidelines. Witness for example the requirement that penalties be ?effective, proportionate and dissuasive?.

In order to be compliant, an energy audit must

  1. Be based on twelve months of verifiable data that is
    • over a continuous period beginning no more than 24 months before the beginning of the energy audit, and;
    • identifies energy saving opportunities including paths to their achievement
  2. Analyse the participant’s energy consumption and energy efficiency
  3. Have not been used as the basis for an energy audit in a previous compliance period

Measurement of current status and progress tracing are at the core of energy saving and good governance generally. EcoVaro has a powerhouse of software tools available on the cloud to help project teams save time and money.

What are the benefits of digital forms data collection
Field Service Workers are regularly engaged to collect data or carry out inspections and assessments when visiting customer sites or remote area locations. The data collected by Field Service workers, will be used by businesses who will analyse, process and build reports based on the large volumes of data collected. The accuracy and reliability of data collected is vitally important. Traditionally businesses may have deployed mail surveys, telephone interviews, door-to-door surveys and interviews performed by Field Workers to collect data. Digital Transformation is gradually changing many business operations and a great deal of processes which were traditionally executed manually are now accomplished making use of digital methods. Technology is having a major impact not only how businesses research and analyse data, but primarily how data and information is collected. New tools and processes to data collection are improving data collection and analysis, leading to dramatic improvements and maximisation and optimisation of resources and operations. Utilising Digital Data Collection methods enables organisations to not only obtain results quicker but also use the data to make data based decisions faster.

What is a Digital Form?

Digital Forms, also known as Mobile Forms are electronic versions of paper forms that can be completed using:
  • Laptop
  • Tablet
  • Smart Phone
  • Any Mobile Device

Why Use Digital Forms ?

Digital forms can be a simple yet highly effective solution to overcome the challenges presented by paper based forms. Digital forms can be filled out directly using Smart phones and tablets in the field
  • When not connected to the internet or even low speed internet connections
  • When working in remote locations
  • To avoid damage, illegible handwriting or even lost and misplaced forms.
Digital forms can also include data validation logic to ensure field workers complete every form as expected and required, which will enforce and ensure data integrity . Field Service teams appreciate these features and help ensure the validity and accuracy of the data and insights they collect and can be confident regarding making business critical data based decisions. Data and Information collected using mobile forms can be accessible in near real-time, helps enable field teams to sidestep potential obstacles to productivity, and act on opportunities and increasing business agility.

Advantages of Digital Forms

Time and Cost Saving

Using Digital Forms instead of paper-based forms provides a significant impact on improving time and cost savings on printing, storing and distribution costs. Businesses also spend a significant amount of time and money in Administration and double data entry processes incurred by paper based forms. Transferring information from paper based surveys is an error prone process.
Digital Forms can save up to 20 man hours a week in administration costs

Improve data accuracy

Digital Forms can auto-populate fields based on prior data entered and also enable field-level validation. Digital data collection also eliminated data entry errors and data loss. Additional data can also be automatically be gathered such as Username, Geo-location and Time & Date.

Real Time Reporting

The issue with Paper-based data collection is that there will always be a time lag before reports or decision can be made. With a digital platform, such as FieldElite – Mobile Workforce Management , data can be processed and analysed as it is collected. Providing data driven insights to provide proactive rather than reactive reports to improve and optimise operations in real time.

Shared Services ? Are They A Good Idea

Things happen fast in business and we need to stay on top. It does not seem long ago that some enterprises were still hands-on traders or artisans with a few youngsters to help out. People like that did not do admin and their accounting was a matter of making sure there was enough money in the jar.

When Wal-Mart’s Sam Walton took over his first shop in 1945 things had moved on from there, although he did still deal directly with his customers. When he died his legacy was 380,000 jobs, and a business larger than most economies. So there?s plenty we can learn from how he grew his business.

One of Sam?s secrets was his capacity to centralise what needed gathering together, while empowering store managers to think independently when it came to local conditions. His regional warehouses had individual outlets clustered around them within one day?s drive each. This shared service eliminated 90% of safety stock and released capital for expansion.

Wal-Mart took sharing services a step further in February 2006, when it centralised accounts payable, accounts receivable, general accounting and human resources administration at Wal-Mart Stores and Sam?s Clubs in the U.S. and Puerto Rico. The objective was to bring costs down, while allowing local managers more time to focus on their business plans and other initiatives. As a further spin-off, Wal-Mart was able to integrate its data on a single SAP platform and eliminate significant roadblocks.

This is an excellent example of sharing services by creating own centres of excellence.? Of course, this is not the only business possibility. Other corporates have successfully completely outsourced their support activities, and Wal-Mart has no doubt had a variety of similar offers too. But, is the Wal-Mart picture entirely rosy, or is there a catch?

The Association of Chartered Certified Accountants has indicated that top talent may be the loser globally. This is because the Wal-Mart model removes many challenges through standardisation, and offers less scope for internal promotion as a result. Language and cultural differences may also have a long-term detrimental effect on the way the departments work well together.

Local outsourcing ? this is the business model where several firms engage a shared service provider independently- may hence prove to be a more malleable option for smaller companies. It often makes more sense to hunt down made-to-order services. Offerings such as the professional support we offer on this site.
