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.?

Cloud Computing Trends: Where is the Cloud Headed Next?

Cloud adoption has been quick and painless at the consumer level. For instance, everyone’s on Gmail, YouTube, Facebook and Twitter on a daily basis yet most think nothing of the fact that they’re already using cloud-based services. Small businesses have also discovered how cloud solutions have raised efficiency in the workplace up a notch or two, while also bringing about significant cost savings. Cloud applications, particularly those for communication, file sharing, office software, backup and storage, and customer management, have rapidly grown in usage among SMBs.

In the same manner, large corporations are starting to see the potential of moving some of their IT department, whether its infrastructure or network management, to the cloud. By all indications it would seem that whether we are ready for it or not, cloud computing technology is here for the long haul.

So where is the cloud headed to next? In this post we examine the trends in the world of cloud computing and what likely lies in store in the near future for cloud users.

Focus on Security

Security has always been a key concern in the cloud computing industry and this will not go away anytime soon. If anything, data security in the cloud will only get to be in the limelight even more as cloud adopters grow in number. That’s why we expect professional cloud services providers to start implementing measures that will help slowly build up confidence in cloud security.

We should soon see more advanced security techniques and protocols that would increase the overall level of privacy and protection for cloud-stored information. Tighter security for login encryptions and prevention of unauthorized access are priority although there are a lot more issues that may need to be addressed. Now it remains to be seen whether these moves are enough for corporate clients to put their full trust in the cloud. But then again, they can always find ways to stay secure while making use of cloud computing where they can, which brings us to the next cloud trend.

Hybrid Approach

Large businesses are taking a longer time to get used to and actually use cloud services, and understandably so. After all, these companies have more at stake when it comes to dealing with such valid issues as security, compliance, outages, legacy systems, and more. However, they also cannot ignore the very appealing characteristics of the cloud. For big companies that have substantial IT needs, scalability, business agility, and faster deployment are listed as the biggest draws of the cloud.

This is why analysts predict that as as these businesses look toward leveraging the benefits of the cloud while at the same time maintaining control over mission critical data and systems, the use of a hybrid approach, i.e. putting some services in a public and at the same time opting to utilize a private cloud for other applications, will see enormous growth.

Mobile Cloud Computing

The BYOD or Bring Your Own Device business policy is another emerging trend that would not have been possible if not for cloud technology. This practice involves having employees bring their mobile devices to work, allowing them to access company files, data, and applications from their personally-owned gadgets in and out of the workplace.

As with any new business practice, the concept of BYOD can be both advantageous and disadvantageous. On the one hand, some believe it helps increase employee productivity and lifts their morale, while reducing overall IT costs. On the other hand, BYOD also opens up a whole new set of problems that are quite consistent with what many businesses take issue with with cloud technology: security. Do the pros outweigh the cons or vice versa? This much isn’t clear yet but what is evident is that more cloud apps are going mobile.

Efficiency, Innovation

While cost savings has always been one benefit that cloud proponents are quick to point out, its capability to improve and streamline business processes, thereby increasing efficiency and agility within the organization, is another key opportunity that the cloud offers. This is evident when you take a look at the most commonly used cloud services: backup and archiving, business continuity, collaboration tools, and big data processing.

Moreover, the cloud is making it easier for individuals to create new products and produce new lines of business. With access to higher IT capacity at lesser cost and at faster deployment rates, businesses can scale into more innovation without having to worry about the availability of computing resources.

Symbion Pharmacy Services? Definition of Responsibility

A ?symbion? is an organism in a symbiotic (i.e. mutually beneficial) relationship with another one. In the case of Australia?s giant Symbion Pharmacy Services, this means supplying and delivering over-counter Chemmart medicines to more than 3,000 hospital and retail pharmacies, while remaining mindful of its carbon footprint.

In 1999, the company with the tagline ?life matters? and a desire to be seen as ?a good corporate citizen? decided it was time to measure exactly what it was pumping out from 12 facilities and over 200 vehicles. This was a voluntary decision as even now there is still no carbon emissions law in Australia (although no doubt being a ?first mover? will put the company in a competitive position when this inevitably comes).

Symbion decided to install emission detection devices and connect these to a central monitoring system with the intention of managing what these measured. There were two stages to this process. First, Symbion determined its reporting requirements based on one of its larger warehouses. Following that, it established a carbon footprint for each of its wholly owned and managed facilities. This put it in a position to:

  • Analyse total emissions down to a level of detail where it understood the contribution of each source
  • Use big data management tools to identify carbon hotspots for priority remedial action
  • Inform the affected workforce, explain the monitoring system and keep them in the loop
  • Separately manage energy abatement programs such as lighting and delivery routes

The program also had productivity spin-offs in that it focused management attention on the processes behind the emissions that were ripe for material and system improvements. It also provided marketing leverage. Symbion?s customers are in the wellness business, ahead of the curve when it comes to how emissions contribute to chronic illness, and aware of the cost of this in terms of human capital.

ecoVaro to tackle water stress

For many people within the UK, water is not really something to worry about. Surely enough of it falls out the sky throughout the year that it does feel highly unlikely that we?ll ever run out of it. There certainly does seem to be an abundance of Branded Water available in plastic bottles on our supermarket shelves.

Water, water, every where,
And all the boards did shrink;
Water, water, every where,
Nor any drop to drink.

The Rime of the Ancient Mariner ? Samuel Taylor Coleridge

Despite this, Once-unthinkable water crises are becoming commonplace.  If you consider that In England and Wales, we use 16 billion litres of clean drinking water every day ? that’s equivalent to 6,400 Olympic sized swimming pools.

Currently, water companies can provide slightly more than we need ? 2 billion litres are available above and beyond what we’re using.  In some areas, though, such as south east England, there is no surplus and, as such, these regions are more likely to face supply restrictions in a dry year.

If we take little moment to reflect on some of the most notable water related stories over the past few years, we’ll start to get a picture of just how real the potential and the threat of water shortages can be.

Reservoirs in Chennai, India?s sixth-largest city, are nearly dry right now. Last year, residents of Cape Town, South Africa narrowly avoided their own Day Zero water shut-off.

It was only year before that, Rome rationed water to conserve scarce resources.

Climate change is likely to mean higher temperatures which may drive up the demand for water (alongside population growth) and increase evaporation from reservoirs and water courses during spring and summer.

The impact of climate change on total rainfall is uncertain, but the rain that does fall is likely to arrive in heavier bursts in winter and summer. Heavier rain tends to flow off land more quickly into rivers and out to sea, rather than recharging groundwater aquifers.

A greater chance of prolonged dry periods is also conceivable.  This combined with the harsh reality that no human population can sustain itself without sufficient access to fresh water.

If present conditions continue, 2 out of 3 people on Earth will live within a water-stressed zone by 2025

What is water stress?

Water stress is a term used to describe situation when demand for water is greater than the amount of water available at a certain period in time, and also when water is of poor quality and this restricts its usage. Water stress means deterioration in both the quantity of available water and the quality of available water due to factors affecting available water.

Water stress refers to the ability, or lack thereof, to meet human and ecological demand for water. Compared to scarcity, water stress is a more inclusive and broader concept.

Water Stress considers several physical aspects related to water resources, including water scarcity, but also water quality, environmental flows, and the accessibility of water.

Supply and Demand

Major factors involved when water scarcity strikes is when a growing populations demand for water exceeds the areas ability to service that need.

Increased food production and development programs also lead to increased demand for water, which ultimately leads to water stress.

Increased need for agricultural irrigation in order to produce more crops or sustain livestock are major contributors to localised water stress.

Overconsumption

The demand for water in a given population is fairly unpredictable.  Primarily, based on the fact that you can never accurately predict human behaviour and changes in climate.

If too many people are consuming more water than they need because they mistakenly believe that water is freely available and plentiful, then water stress could eventually occur.

This is also linked to perceived economic prosperity of a give region.  Manufacturing demand for water can have huge impact regardless whether water is actively used within the manufacturing process or not.

Water Quality

Water quality in any given area is never static.  Water stress could happen as a result of rising pollution levels having a direct impact on water quality.

Water contamination happens when new industries either knowingly or unknowingly contaminate water with their industrial practices.

Largely, this can happen and frequently does so because these industries do not take effective control of monitoring and managing their impact on communal water supplies.  Incorrectly assuming this is the responsibility of an additional third party like the regional water company.

The truth is, water quality and careful monitoring of it is all of our responsibility.

Water Scarcity

Simple increases in demand for water can in itself contribute to water scarcity. However,  these are often preceded by other factors like poverty or just the natural scarcity of water in the area.

In many instances, the initial locations of towns or cities were not influenced by the close proximity of natural resources like water, but rather in pursuit of the extraction of other resources like Gold, Coal or Diamonds.

For Instance, Johannesburg,  South Africa is the largest City in South Africa and is one of the 50 largest urban areas in the world. It is also located in the mineral rich Witwatersrand range of hills and is the centre of large-scale gold and diamond trade.

Johannesburg is also one of the only major cities of the world that was not built on a river or harbour.   However, it does have streams that contribute to two of Southern Africas mightiest rivers – Limpopo and the Orange rivers.  However, most of the springs from which many of these streams emanate are now covered in concrete!

Water Stress and Agriculture

Peter Buss, co-founder of Sentek Technology calls ground moisture a water bank and manufactures ground sensors to interrogate it. His hometown of Adelaide is in one of the driest states in Australia. This makes monitoring soil water even more critical, if agriculture is to continue. Sentek has been helping farmers deliver optimum amounts of water since 1992.

The analogy of a water bank is interesting. Agriculturists must ?bank? water for less-than-rainy days instead of squeezing the last drop. They need a stream of real-time data and utilize cloud-based storage and processing power to curate it.

Sentek?s technology can be found in remote places like Peru?s Atacamba desert and the mountains of Mongolia, where it supports sustainable floriculture, forestry, horticulture, pastures, row crops and viticulture through precise delivery of scarce water.

This relies on precision measurement using a variety of drill and drop probes with sensors fixed at 4? / 10cm increments along multiples of 12? / 30cm up to 4 times. These probe soil moisture, soil temperature and soil salinity, and are readily repositioned to other locations as crops rotate.

Peter Buss is convinced that measurement is a means to an end and only the beginning. ?Too often, growers start watering when plants don’t really need it, wasting water, energy, and labour. By accurately monitoring water can be saved until when the plant really needs it.

Peter also emphasises that crop is the ultimate sensor, and that ?we should ask the plant what it needs?.

This takes the debate a stage further. Water wise farmers should plant water-wise crops, not try to close the stable door after the horse has bolted and dry years return.

The South Australia government thinks the answer also lies in correct farm dam management. It wants farmers to build ones that allow sufficient water to bypass in order to sustain the natural environment too.

There is more to water management than squeezing the last drop. Soil moisture goes beyond measuring for profit. It is about farming sustainably using data from sensors to guide us.

Ecovaro is ahead of the curve as we explore imaginative ways to exploit the data these provide for the common good of all.

A Quarter of the World?s Population, Face High Water Stress

Data from WRI?s Aqueduct tools reveal that 17 countries ? home to one-quarter of the world?s population?face ?extremely high? levels of baseline water stress, where irrigated agriculture, industries and municipalities withdraw more than 80% of their available supply on average every year. 

Water stress poses serious threats to human lives, livelihoods and business stability. It’s poised to worsen unless countries act: Population growth, socioeconomic development and urbanization are increasing water demands, while climate change can make precipitation and demand more variable.  

How to manage water stress

Water stress is just one dimension of water security. However, like any challenge, its outlook depends on adequate monitoring and management of environmental data.

Even countries with relatively high water stress have effectively secured their water supplies through proper management by leveraging the knowledge they have garnered by learning from the data they gathered.

3 ways to help reduce water stress

In any geography, water stress can be reduced by measures ranging from common sense to innovative technology solutions.

There are countless solutions, but here are three of the most straightforward:

1. Increase agricultural efficiency: The world needs to make every drop of water go further in its food systems. Farmers can use seeds that require less water and improve their irrigation techniques by using precision watering rather than flooding their fields.

Businesses need to increase investments to improve water productivity, while engineers develop technologies that improve efficiency in agriculture.

Consumers can reduce food loss and waste, which uses one-quarter of all agricultural water.

2. Invest in grey and green infrastructure:  D Data produced by Aqueduct Alliance  –  shows that water stress can vary tremendously over the year.  WRI and the World Bank?s research shows that built infrastructure (like pipes and treatment plants) and green infrastructure (like wetlands and healthy watersheds) can work in tandem to tackle issues of both water supply and water quality.

3. Treat, reuse and recycle:  We need to stop thinking of wastewater as waste.

Treating and reusing it creates a ?new? water source.

There are also useful resources in wastewater that can be harvested to help lower water treatment costs. For example, plants in Xiangyang, China and Washington, D.C. reuse or sell the energy- and nutrient-rich byproducts captured during wastewater treatment.

Summary

The data is undeniably clear, there are very worrying trends in water.

Businesses and other other organisations need to start taking action now and investing in better monitoring and management, we can solve water issues for the good of people, economies and the planet. We collectively cannot kick this can down the road any further, or assume that this problem will be solved by others.

It is time, for a collective sense of responsibility and for everyone to invest in future prosperity of our Planet as a collective whole.  Ecological preservation should be at the forefront of all business plans because at the end of the day profit is meaningless without an environment to enjoy it in!
