Saving Energy Step 1 ? Implementing a Management System

There has been much hype down the years regarding whether management is art or science. Thankfully, where people are concerned the pendulum has swung away from standard times in sweatshops in the west. However, when it comes to measuring physical things like harvest per square meter and the amount of energy consumed there is no substitute for scientific measurement, and this implies a system.

Managing energy cost and consumption down is like any other strategy. American engineer / statistician / management consultant W. Edwards Demming may have passed on in 1993. However he was as right as ever when he said:

  1. When people and organizations focus primarily on quality, this tends to increase and costs fall over time.
  1. However, when people and organizations focus primarily on costs, costs tend to rise and quality declines over time.

Demming believed that 90% of organizational problems arise from systems we put in place ourselves. This can be because we are so accustomed to them that we fail to notice when they are no longer relevant. The currently prevailing laissez faire towards energy is a case in point. What is managed improves and what is not, deteriorates. We know this. Let us take a look at how to apply this principle to energy management.

First, you need to get the subject out the closet and talk about it. How often do you do this is your boardroom, and how does energy rank against other priorities? Good governance is about taking up a position and following through on it. Here is a handy checklist you may like to use.

  • Do we use a consistent language when we talk about energy? Is it electricity, or carbon emitted (or are we merely fretting over cost).
  • How well engaged are we as a company? Looking up and down and across the organization are there points where responsibility stops.
  • How well have we defined accountability? Do we agree on key performance areas and how to report on them.
  • Are we measuring energy use at each point of the business? When did we last challenge the assumption that ?we’re doing okay?.
  • Have we articulated our belief that quality is endless improvement, or are we simply chasing targets because someone says we should.

A management system is a program of policies, processes and methods to ensure achievement of goals. The next blog focuses on tools and techniques that support this effort.

Big Energy Data Management

Recent times have seen the advent of cloud based services and solutions where energy data is being stored in the cloud and being accessed from anywhere, anytime through remote mobile devices. This has been made possible by web-based systems that can usually bring real-time meter-data into clear view allowing for proactive business and facility management decisions. Some web based systems may even support multi utility metering points and come in handy for businesses operating multiple sites.

Whereas all this has been made possible by increased use of smart devices/ intelligent energy devices that capture data at more regular intervals; the challenge facing businesses is how to transform the large data/big volume of data into insights and action plans that would translate into increased performance in terms of increased energy efficiency or power reliability.

A solution to this dilemma facing businesses that do not know how to process big energy data, may lie in energy management software. Energy management software?s have the capability to analyse energy consumption for, electricity, gas, water, heat, renewables and oil. They enable users to track consumption for different sources so that consumers are able to identify areas of inefficiency and where they can reduce energy consumption, Energy software also helps in analytics and reporting. The analytics and reporting features that come with energy software are usually able to:

? Generate charts and graphs ? some software?s give you an option to select from different graphs

? Do graphical comparisons e.g. generate graphs of the seasonal average for the same season and day type

? Generate reports that are highly customisable

While choosing from the wide range of software available, it is important for businesses to consider software that has the capacity to support their data volume, software that can support the frequency with which their data is captured and support the data accuracy or reliability.

Energy software alone may not make the magic happen. Businesses may need to invest in trained human resources in order to realise the best value from their big energy data. Experts in energy management would then apply human expertise to leverage the data and analyse it with proficiency to make it meaningful to one?s business.

Energy Management Tips

Energy management is of interest to various stakeholders; be it heads of facilities, heads of procurement, heads of environment and sustainability, financial officers, renewable energy managers and heads of energy. Some of the energy management tips that can be used to achieve considerable energy savings are:

1) Purchasing energy supplies at the lowest possible price

2) Managing energy use at peak efficiency

3) Utilising the most appropriate technology

1. Purchasing energy supplies at the lowest possible price
Purchasing energy supplies at the lowest possible price could be the starting point to great savings of energy costs. This can be achieved through switching your energy supplier. It is always advisable for companies to always take time to compare the energy tariffs to ensure they are on the best tariff and make great savings.

2. Managing energy use at peak efficiency

(a) Free help

There are some online tools that offer energy-efficiency improvements. These could come in handy in helping someone find out where to make energy-efficiency improvements.

(b) Energy monitors

An energy monitor is a gadget that estimate in real time how much energy you’re using. This can help one see where to cut back on energy consumption.

(c) Turning down thermostats

Turning down radiators especially in rooms that are rarely used/empty rooms or programming the heating to turn off when no one is there can go a long way in saving energy and energy costs.

(d) Use energy saving bulbs

Use of energy-saving light bulbs can cut down on energy usage drastically. Replacing all the light bulbs with energy-saving ones could make significant savings on energy usage and replacement costs since energy saving bulbs also have a longer life.

(e) Switching off unnecessary lights

It is also important to switch off lights that are not in use and to use the best bulb for the size of room.

(f) Sealing all heat escape routes

It is recommended that all gaps should be sealed in order to stop heat from escaping. Some of the heat escape routes are: windows, doors, chimneys and fireplaces, floorboards and skirting and loft hatches. The ways through which this can be achieved are:

? Windows- use of draught-proofing strips around the frame, brush strips work better for sash windows

? Doors – use of draught-proofing strips for gaps around the edges and brush or hinged-flap draught excluders on the bottom of doors

? Chimney and fireplace – inflatable cushions can be used to block the chimney or fit a cap over the chimney pot on fireplaces that are not used often

? Floorboards and skirting – Using a flexible silicon-based filler to fill the gaps

? Loft hatches – the use of draught-proofing strips can help to prevent hot air escaping
It is also important to consider smaller holes of air such as keyholes and letterboxes.

3. Utilising the most appropriate technology
Utilisation of technology as an energy management tool can be by way of choosing more energy efficient gadgets and by way of running technological gadgets in an energy efficient manner.

FUJIFILM Cracks the Energy Code

FUJIFILM was in trouble at its Dayton, Tennessee plant in 2008 where it produced a variety of speciality chemicals for industrial use. Compressed-air breakdowns were having knock-on effects. The company decided it was time to measure what was happening and solve the problem. It hoped to improve reliability, cut down maintenance, and eliminate relying on nitrogen for back-up (unless the materials were flammable).

The company tentatively identified three root causes. These were (a) insufficient system knowledge within maintenance, (b) weak spare part supply chain, and (c) generic imbalances including overstated demand and underutilised supply. The maintenance manager asked the U.S. Department of Energy to assist with a comprehensive audit of the compressed air system.

The team began on the demand side by attaching flow meters to each of several compressors for five days. They noticed that – while the equipment was set to deliver 120 psi actual delivery was 75% of this or less. They found that demand was cyclical depending on the production phase. Most importantly, they determined that only one compressor would be necessary once they eliminated the leaks in the system and upgraded short-term storage capacity.

The project team formulated a three-stage plan. Their first step would be to increase storage capacity to accommodate peak demand; the second would be to fix the leaks, and the third to source a larger compressor and associated gear from a sister plant the parent company was phasing out. Viewed overall, this provided four specific goals.

  • Improve reliability with greater redundancy
  • Bring down system maintenance costs
  • Cut down plant energy consumption
  • Eliminate nitrogen as a fall-back resource

They reconfigured the equipment in terms of lowest practical maintenance cost, and moved the redundant compressors to stations where they could easily couple as back-ups. Then they implemented an online leak detection and repair program. Finally, they set the replacement compressor to 98 psi, after they determined this delivered the optimum balance between productivity and operating cost.

Since 2008, FUJIFILM has saved 1.2 million kilowatt hours of energy while virtually eliminating compressor system breakdowns. The single compressor is operating at relatively low pressure with attendant benefits to other equipment. It is worth noting that the key to the door was measuring compressed air flow at various points in the system.
