Deploying an Energy Management System!

devices_logoSTEP 1 – Install Measurement Devices

Step 1 of getting your Energy Management System (EnMS) up and running is deciding on “What” and “Where” you want to measure/monitor and “How” you want to manage your consumption. This is often decided by the significant energy usage at your installation.

Possible “What” and “Where” you want to deploy measurement devices are Electrical DBs, Water Metering, Gas Metering, Lighting Intensity, Area Temperature, Compressed Air and HVAC.

You can define “How” to do Energy Management by either “Area” or “Process” or a combination of both. The only rule here is that you need to cover significant energy usage.

 

STEP 2 – Get Communication Working

Step 2 involves establishing a communication link between your deployed measurement devices (Step 1) and your control system (Step 3). RS485 cabling is the most common communication method but increasingly RF and TCP/IP are being used.

It is best (if possible) to piggyback on an existing communication system at your installation such as LAN, Wi-Fi, Profibus, etc. Using existing communication systems reduce the cost and effort required to get your EnMS up and running. Additionally you don’t have to independently maintain the communication system.

If this is not possible, select a suitable communication method based on your budget and installation condition. A combination or hybrid communication network, which is optimized for the installation, can also be deployed.

 

i3EnMS ArchitectureSTEP 3 – Setup Control System

Step 3 is about setting-up your control system to perform data acquisition from installed measurement devices (Step 1) thru the communication network (Step 2).

You need to determine the parameters that you need to log and your logging frequency. The EnMS objective plays an important part in deciding the required parameters and logging interval.

This step also involves setting up the roles and responsibilities of your EnMS team members. Access and features can be selectively assigned to individual EnMS team members based on their role.

Most importantly, you setup your EnPI (Energy Performance Indicators) benchmarking frequency and parameter for each process / area in your EnMS.

Step 4 is the final step in getting you EnMS operational. Here the face of the EnMS is setup and this decides the success of engagement with your EnMS.

Based on your EnMS objectives, you can configure various analytics charts, tables, reports and alerts. SMS and email alerts are features that enable a fully automated EnMS environment.

Analytics feature in i3EnMS enables display and generation of reports based on “Consumption Trend Monitoring”, “Consumption Trend Comparison”, “MD Trend Monitoring”, “MD Trend Comparison”, “Area/Process Consumption & Trend”, “Consumption Breakdown” and “Energy Cost Analysis” among others.

The last activity is to configure the broadcast of EnMS data on external LCD TVs, both single and multiple throughout the organization (either showing total or selective area Energy Performance). This is an important feature that enables the development of “Energy Efficient Culture” in the organization, as everyone will have access to data on their consumption.

How to reduce your energy bills?

Organizations are currently faced with ever-increasing energy bill that adds cost and affects the bottom-line.

While some are resigned to paying higher bills, most are scrambling to implement “something” which will enable them to reduce their energy bills. Before doing “something”, you need to understand what the “something” should do to achieve reduced energy consumption.

The only way to reduce energy consumption is by improving your “Energy Performance”.

By improving your “Energy Performance”, you obtain a higher output for the same unit of energy that you consume. In effect, the “something” should lead to a better “Energy Performance”.

“Energy Performance” is measured by using EnPI (Energy Performance Indicators).

EnPI_formula

 

 

 

Improve “Energy Performance”

Any measure undertaken to increase ”Energy Performance” falls under one of the following category:

  • Maintenance Improvement
  • Energy Consumption Culture
  • Energy Efficient Technology

This means that any “something” implemented to reduce cost (improve “Energy Performance”) will fall under one of these three categories.

EnMS_benefits

 

Improved Maintenance

Perhaps the biggest contributor to “Energy Performance” improvement but the least focused upon activity.

Most organizations deploy a periodic maintenance program based on the equipment manufacturers’ recommendations.

An EnPI based maintenance program will further add value by improving the energy performance and ensuring high operational reliability of the equipment.

Examples of Maintenance Improvement:

Compressed Dry Air

  1. Detect and repair air leaks
  2. Proper lubrication or usage of synthetic lubricants
  3. Cleaning and replacement of filters

Chiller & AHU

  1. Clean evaporator and condenser tubes
  2. Prevent scale (descaling), algae & biofilm
  3. Air filter cleaning and replacement
  4. Cleaning cooling coils

Motors

  1. Periodic greasing
  2. Motor alignment
  3. Bearing replacement

 

Energy Efficient Culture

The prevailing culture in an organization can either promote or hinder efficient energy utilization. EnPI can accurately measure and  provide a platform upon which Energy Efficient Culture improvement activities can be carried out.

 

Energy Efficient Technology

The most overrated of “Energy Performance” improvement action category. Also where the biggest loss of opportunity occurs due to inadequate measurement & monitoring.

EnPI can accurately assess the potential “Energy Performance” improvement of various Energy Efficient Technology solutions and simplify selection.

 

Measuring, monitoring and managing “Energy Performance” with EnPI ensures results are achieved and maintained.

i3 EnMS -> Complete & Comprehensive Energy Management Platform

We analysed the EnMS solutions available on the market and came to the following conclusion

  • existing offerings are expensive to deploy.
  • required a high degree of technical competency (which again increased the cost of deployment).
  • disrupts operations at the organization during EnMS deployment.
  • lacked Energy Performance Indicator benchmarking & reporting.
  • unable to broadcast the Energy Performance data to general majority in an organization.

Medium and small sized organization would find it difficult in overcoming the resistance to the deployment of an EnMS and Energy Performance improvement would bypass the majority of significant consumers.

We set out to develop a solution that would plug this hole and make EnMS available to the entire spectrum of the market. Out of this need, our i3EnMS Energy Management Platform was born.

i3EnMS

 

 

 

 

 

An EnMS is made of three main components:

  1. Measurement Devices
  2. Data Communication Network
  3. Control System

Our solution had to have the following features:

  1. Cost effective in terms of low capax and low opex.
  2. Easily deployable without much disruption to the installation and avoid the pitfalls associated with fit and retrofit activities.
  3. It had to be easy where any competent electrician would be able to deploy it.
  4. Comprehensive enough so that all the features required for EnMS are present.
  5. Open platform so that existing investment in hardware is usable and does not restrict selection of new hardware for future installation / upgrade.

i3EnMS Architecture

 

 

In addressing these requirements, our i3EnMS Energy Management Platform was designed:

  1. To be “Hardware Agnostic”… totally compatible with any/all available power meters/power analyzers. This ensured existing investment is still usable and new investment of hardware is totally open and not restricted to any make or model. Additionally, any device which has RS485 communication can be integrated into i3EnMS.
  2. Our i3NET data communication module in i3EnMS is able to utilize multiple communication modes in parallel, which translates into total flexibility in selecting the communication mode. Both wired and wireless communication modes can be used, with wired solutions being RS485 cables, LAN network and over existing power lines… the wireless include WIFI, Industrial RF and Zigbee.
  3. Our Control System came pre-configured with standard reports and screens. It could be easily customized to each installation and features one of a kind mimic LCD display output, where the energy consumption data is sent to an external display (such as a LCD TV). The MIMIC display in our opinion is a critical component of the EnMS as real-time and historical energy consumption information of the installation is available for everyone. The broadcast of energy consumption data and trend promotes an energy efficient culture within the organization.

To sum up, our i3 EnMS a complete and comprehensive Energy Management platform that can be easily and cost effectively deployed.

ISO launches ISO 50001 energy management standard…

With energy one of the most critical challenges facing the international community, the publication on 15 June of the ISO International Standard ISO 50001 on energy management systems is an eagerly awaited event because it is estimated the standard could have a positive impact on some 60 % of the world’s energy use.

ISO50001

ISO 50001 will provide public and private sector organizations with management strategies to increase energy efficiency, reduce costs and improve energy performance.

The standard will be available on the ISO Website www.iso.org on 15 June. In addition, ISO is launching the standard on 17 June at the Geneva International Conference Centre (CICG). Presentations on the following themes are planned:

ISO 50001 within the context of ISO standards in general and how they can contribute to solving global problems
A description of ISO 50001 and its benefits
How the standard was developed, who was involved and how they overcame challenges
What ISO 50001 can do for developing countries.
ISO Secretary-General Rob Steele comments: “Energy is critical to organizational operations and can be a major cost to organizations, whatever their activities. An idea can be gained by considering the use of energy through the supply chain of a business, from raw materials through to recycling.

“Individual organizations cannot control energy prices, government policies or the global economy, but they can improve the way they manage energy in the here and now. Improved energy performance can provide rapid benefits for an organization by maximizing the use of its energy sources and energy-related assets, thus reducing both energy cost and consumption. The organization will also make positive contributions toward reducing depletion of energy resources and mitigating worldwide effects of energy use, such as global warming.”

ISO 50001 is intended to provide organizations with a recognized framework for integrating energy performance into their management practices. Multinational organizations will have access to a single, harmonized standard for implementation across the organization with a logical and consistent methodology for identifying and implementing improvements. The standard is intended to accomplish the following:

Assist organizations in making better use of their existing energy-consuming assets
Create transparency and facilitate communication on the management of energy resources
Promote energy management best practices and reinforce good energy management behaviours
Assist facilities in evaluating and prioritizing the implementation of new energy-efficient technologies
Provide a framework for promoting energy efficiency throughout the supply chain
Facilitate energy management improvements for greenhouse gas emission reduction projects
Allow integration with other organizational management systems such as environmental, and health and safety.

ISO 50001 energy management standard impacts the bottom line…

ISO50001Substantial improvements in energy efficiency with positive financial impacts have been experienced both by a major company and by a small business taking part in a pilot program to test the new ISO 50001 energy management standard.

These results were reported on 17 June 2011 at the launching by ISO of the new standard at the Geneva International Conference Centre (CICG), Switzerland.

ISO Secretary-General Rob Steele told the international audience of nearly 200 people attending the event: “Energy is no longer a technical issue, but a management issue with an impact on the bottom line and the time to address the issue is now.”

The event included presentations by three out of some 100 experts from 45 countries who participated in developing the standard.

Ken Hamilton, Director, Global Energy and Sustainability Services, Hewlett Packard (USA), described ISO 50001 as a “very pragmatic standard” which will help companies to integrate energy management with business practices. It will allow multinational companies like Hewlett Packard to reduce energy costs and increase the efficiency of energy use throughout global supply chains.

Mr Hamilton quoted results from two pilot implementations which were part of the Superior Energy Performance programme sponsored by the US Council for Energy Efficient Manufacturing and the US Department of Energy.

Why i3EnMS

He cited the experience of two plants. One of them was a plant owned by a major company, Dow Chemicals. The plant reduced its use of energy by 17.9 % over two years. At the same time, ISO 50001 principles are also successfully implemented by small businesses as shown by the experience of the other plant, CCP, of Houston, Texas, employing 36 people. In two years, it achieved energy savings of 14.9 %, worth USD 250 000 a year with zero capital investment.

Alberto J. Fossa, Director, International Copper Association/MDJ, Brazil, underlined the international expertise that had been distilled in ISO 50001, with meetings to develop the standard held in China, the USA, Brazil and the United Kingdom.

At these, a common understanding had been forged between experts in technical efficiency on the one hand and in management on the other to produce a standard that will help all types of organization to achieve continual improvement of their energy performance.

Marco Matteini, of the Industrial Energy Efficiency Unit, the United Nations Industrial Development Organization (UNIDO), said that forecasts of future energy demand highlighted substantial increases in developing countries, thus underlining the importance and relevance of ISO 50001 for organizations in emerging economies.

The launch event, moderated by the ISO Director of Marketing, Communication and Information, Nicolas Fleury, saw the first public showing of the short video, ISO and energy management. This video is among the material available on a multimedia news release published on the ISO Website, making the launch event available to a worldwide public. It includes video interviews of the speakers, videos of their presentations, their PowerPoint slides, the new ISO brochure Win the energy management challenge with ISO 50001, and links to related ISO material.
