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.?

ESOS ? Why we must have it

The 9,000 big UK businesses directly affected by the new Energy Saving Opportunity Scheme could save UK?250 million between them, or an average UK?27,000 each, if they reduced electricity consumption by just 1%. The total amount is equal to the output of five power stations, at a time when Britain?s grid is under strain.
On 26 November 2014, UK Energy and Climate Change Secretary Ed Davey met with over 100 opinion makers from businesses, charities and universities at the Institute of Directors. The gist of what he presented was:

  • ?Britain?s big firms are spending around ?2.8 billion extra each year on inefficient energy technologies ? the equivalent output of nearly five power stations;
  • Now is the time to seize the opportunity with ESOS ? and organisations up and down the country are already gearing up to make changes to save energy, save money and save the environment.
  • If business did what business is supposed to do [that is innovate to make money] and act and invest, it will save ? and that’s the bottom line.?

The environmental benefits are as important although EcoVaro agrees with Ed Davey for taking a pecuniary approach. Businesses above the threshold of 250 staff and a balance sheet of UK?34 million would have not achieved their status unless they spent their money wisely.
The discussion panel included Rhian Kelly (Director of Business Environment at CBI), and Paul Ekins (Director UCL Institute for Sustainable Resources & Deputy Director of the UK Energy Research Centre). Hugh Jones, Managing Director, Advisory at the Carbon Trust responded to Ed Davey?s remarks by commenting:

  • ?At the Carbon Trust we have already engaged with hundreds of businesses on ESOS, helping to explain how they can achieve compliance while also making significant energy savings and cutting carbon.
  • Businesses often aren’t aware of opportunities in energy efficiency, or they don’t realise how attractive the paybacks can be. By requiring companies to understand exactly how they can make cost-effective investment in energy efficiency, they are far more likely to take action.
  • From the interest we have seen so far we expect ESOS to benefit British business by helping companies to reduce overheads and increase competitiveness.

The UK?s Energy Saving Opportunity Scheme ESOS is a gold mine of opportunities for big business, the environment and the population that breathes the air. Measurement of critical energy throughputs is the beginning of the process. EcoVaro is standing by to help you convert your data to meaningful information.

Eliminate The Complexities Of Your IT System

There may have been times when you actually spent on the right IT system but didn’t have adequate expertise to instil the appropriate learning curve for your end users. Oftentimes, users find a new system too complicated and end up spending more hours familiarising with intricate processes than is economically acceptable.

There are also applications that are just too inherently sophisticated that, even after the period of familiarisation, a lot of time is still spent managing or even just using them. Therefore, at the end of each day, your administrators and users aren’t able to complete much business-related tasks.

The first scenario can be solved by providing adequate training and tech support. The second might require enhancements or, in extreme cases, an overhaul of the technology itself.

For instance, consider what happens right after the conclusion of a merger and acquisition (M&A). CIOs from both sides and their teams will have to work hard to bring disparate technologies together. The objective is to hide these complexities and allow customers, managers, suppliers and other stakeholders to get hold of relevant information with as little disruption as possible.

One solution would be to implement Data Warehousing, OLAP, and Business Intelligence (BI) technologies to handle extremely massive data and present them into usable information.

These are just some of the many scenarios where you’ll need our expertise to eliminate the complexities that can slow your operations down.

Here are some of the solutions and benefits we can offer when we start working with you:

  • Consolidated hardware, storage, applications, databases, and processes for easier and more efficient management at a fraction of the usual cost.
  • BI (Business Intelligence) technologies for improved quality of service and for your people, particularly your managers, to focus on making decisions and not just filtering out data.
  • Training, workshops, and discussions that provide a clear presentation of the inter-dependencies among applications, infrastructure, and the business processes they support.
  • Increased automation of various processes resulting in shorter administration time. This will free your administrators and allow them to shift their attention to innovative endeavours.

How Westin Melbourne Hotel Trimmed its Footprint

Becoming sustainable is a three-pronged process. You must save money and push the buttons the government is pressing you to. But there?s a deeper, more urgent issue. If your customers mark you down for not being green enough you are heading for trouble. Let’s see how well this hotel is doing.

The Melbourne flagship of the Westin hotel chain boasts 262 spacious rooms with views of Melbourne Square and surrounding theatres, designer boutiques, galleries and national landmarks. The architects included conference facilities, a wellness centre and sundry bars and restaurants. After climate change arrived to stay, hotel management discovered they had inherited a water and energy-greedy monster. Their solution was to measure what was going through their systems, and then progressively cap the building?s greedy appetite.

The Melbourne Westin Hotel could not have achieved results without these metrics. They began by determining key indicators and measuring them. This provided them with criteria to set achievable, cost effective targets in the following key areas of their business:

  1. Water Management ? Demand-based linen and towel recycling, installation of back-washable water filters, water-saving shower heads, dual-flush toilets.
  2. Waste Management ? Conversion to green products, recycling kitchen oil, moving towards a paperless office, recycling everything possible.
  3. Energy Management ? Energy-efficient light bulbs, standby settings for lights, computers, televisions and air conditioners
  4. Stakeholder Communication ? Staff green-team training, guest education, ongoing employee briefings
  5. Strategic Positioning ? Visible, top-down commitment, optimised carbon offsets from clean, renewable energy sources, clearly stated position in the market

Westin?s Melbourne landmark has made good progress towards becoming the green hotel for others to follow. It has adjusted its environmental policies, increased water and energy awareness and implemented tight waste management.

Consumers are already shopping to make their carbon footsteps lighter. Food stores are on the bandwagon although apparel is lagging. Perhaps it’s time you found out just how your company is shaping up. It’s no longer a matter of ?if carbon taxes?. It’s a matter of ?when it does?.

ecoVaro is a software system-in-the-cloud that lets you enter your water and energy consumption and process it online so you can monitor and manage your usage. In no time at all you could be saving money like Westin Melbourne did. Does that sound like something worth investigating?
