ISO 50001 energy management standard targeted for publication in 3Q2011

Against a background of rising world energy prices, ISO’s announcement of a third quarter 2011 target for publication of its ISO 50001 International Standard for energy management is particularly timely. ISO 50001 will help organizations to improve their energy performance, increase energy efficiency and reduce climate change impacts.

ISO 50001 will establish a framework for industrial plants, commercial facilities or entire organizations to manage energy. Targeting broad applicability across national economic sectors, it is estimated that the standard could influence up to 60 % of the world’s energy use.

ISO 50001 is being developed by ISO project committee ISO/PC 242, Energy management, whose Chair, Edwin Piñero, comments: “Everyday, organizations all over the world deal with issues such as energy supply availability, reliability, climate change, and resource depletion. A critical element in addressing these issues is how effectively an organization manages its energy use.

“ISO 50001 provides a proven model that helps organizations systematically plan and manage their energy use. With a strong focus on performance and continual improvement, ISO 50001 will contribute to enhanced energy efficiency and prudent energy use. An extremely high level of consensus drove our committee’s fast progress toward publication – proof that the world needs and wants this standard.”

The secretariat of ISO/PC 242 is provided by the partnership of the ISO members for the United States (American National Standards Institute – ANSI) and Brazil (Associação Brasileira de Normas Técnicas – ABNT). Forty-three ISO member countries are participating in its development, with another 12 as observers. Liaison organizations include the United Nations Industrial Development Organization (UNIDO) and the World Energy Council (WEC).

The document is based on the common elements found in all of ISO’s management system standards, assuring a high level of compatibility with ISO 9001 (quality management) and ISO 14001 (environmental management). ISO 50001 will provide the following benefits:

• A framework for integrating energy efficiency into management practices
• Making better use of existing energy-consuming assets
• Benchmarking, measuring, documenting, and reporting energy intensity improvements and their projected impact on reductions in greenhouse gas (GHG) emissions
• Transparency and communication on the management of energy resources
• Energy management best practices and good energy management behaviours
• Evaluating and prioritizing the implementation of new energy-efficient technologies
• A framework for promoting energy efficiency throughout the supply chain
• Energy management improvements in the context of GHG emission reduction projects

Management commitment is an important element for successful energy efficiency programme

Sometimes the top management has put a lot of efforts and support to ensure the successful of energy conservation programme. However the result is still below expectation. It may because of the effort is not visible to the employee. It is very difficult to gauge the commitment of the management in organisation toward the energy efficiency. A good organisation should be able to demonstrate their commitment on the energy issues. This is to set an example to the whole organisation and also to convey the message that the management has taking very seriously in implementing the energy efficiency programme. The key driver for the organisation to embark into energy efficiency is mainly for the cost saving. Some big companies has set their carbon footprint on the environmental and GHG emissions reduction as part of its corporate social responsibility. This is also to one of the way for the company to show its commitment toward environmental effort to the public.

Direct participation by the highest level executives in a specific and critically important aspect or program of an organization. In quality management it includes (1) setting up and serving on a quality committee, (2) formulating and establishing quality policies and objectives, (3) providingresources and training, (4) overseeing implementation at all levels of the organization, and (5) evaluating and revising the policy in light of results achieved- Sources: BusinessDictionary.com

However for the middle management and below including the operators and cleaners, may find this very hard to understand. It is merely because the benefits of energy saving and conservation are not directly impacted to these groups of people due to its nature scope of work. This is where the management has to play an important role in increasing the awareness level to these groups.

There are several important elements usually done by the organisation to demonstrate energy management in the organisation.

1) Staff resources. To show the support, management must allocate adequate resources in terms of manpower to ensure the Energy Manager have enough workforce to carry out his job.

However, what is the management should provide? How many personnel should they allocate? The basic team for energy management consist of energy champion, energy manager and energy leader. What is their role?

Energy Champion. The energy champion is a person where he/she posses among the top management level. Some organisation also define the Energy Champion as Energy sponsor. A senior member of management at the corporate and/or facility level who institutes the Energy Management Team, sets their high-level goals, and approves resources and funding for the team and its approved projects. He will become the management representative at energy management working level. The Champion role is to convey the management directions on energy policy and objectives to Energy Manager. He will oversee the overall programs and to ensure it is inline with management target. The champion will be the middle man between the Energy Manager and company’s top management. The main function of this position is to update the energy programme as well highlighting the barriers to the management. The Champion will play role as a management support to the Energy Management team headed by the Energy manager. This senior member gives (or delegates to other facility senior management) presentations at the energy management assessment tool meetings and employee kick-off meeting.

Besides that, the Energy Champion and Energy manager will be supported by the energy team member. All members should be formally appointed by the management as part of their work recognitions. All members of the team will be responsible for helping the Energy Champion to promote energy efficiency, resource conservation, and best management practices throughout the facility. With the help of their fellow team members and outside resources, they will increase their personal knowledge of resource/energy management, help to raise the level of awareness among all employees and assist the Champion with committee projects and activities as needed. Team members are expected to attend regular meetings called by the Champion.

2) Another important element for the management to portray its energy efficiency commitment is through the budget given to the energy team in implementing the programme. This is apart from the budget for energy efficiency project itself. (continued)

LED Lighting: What You Need to Know Before You Buy

This article is taken from Source: http://www.sxc.hu/ , good tips and information regarding the LED lighting.
Key Points

• Only one-third of LED lighting products tested live up to manufacturer's claims.
  
• Look for product testing, accreditations, warranty, chip suppliers, and other indications of quality.
  
• Consider product features such as light output and lumen depreciation for your specific application.

Light-emitting diode (LED) technology is one of the most exciting developments in energy-efficient lighting. Like any new technology however, it has experienced growing pains. In fact, only about one-third of all LED lighting products tested live up to manufacturer's claims, according to U.S. Department of Energy research (DOE 2009). Given these odds, how can you be sure you have the information you need to make the right purchasing decision?
A panel of lighting experts at the 2010 LightFair International Conference addressed this question and developed a checklist of things to look for. The following is a list of the 10 questions you should ask when choosing LED products for your lighting application:

1. To what quality standards has the product been tested? Quality standards for LED products are still in the early stages of development, but testing procedures are available from the following trusted organizations:
   • UL 8750 Safety Standard for LED Equipment for Use in Lighting Products is available through Underwriter's Laboratory.
     
   • The Illuminating Engineering Society of North America has developed IESNA LM-79-08 Approved Method: Electrical and Photometric Measurements of Solid-State Lighting Products and IESNA LM-80-08: Approved Method: Testing Lumen Maintenance of LED Light Sources to measure overall performance and light output over time.
2. What quality accreditations apply?
   
   • ENERGY STAR qualified LED lighting products must meet specific criteria in brightness, lumen maintenance, color quality, and other performance standards.
   • Lighting Facts Label. A voluntary program sponsored by the U.S. Department of Energy (DOE), the label displays important measures such as light output, efficacy, color rendering, and light color—tested according to IESNA LM-79-08 standards
   • Next Generation Luminaires is an annual design competition highlighting LED products that demonstrate high-quality lighting and consistency, glare control, lumen maintenance, and luminaire appearance.
3. Whose LED chips are used in the luminaire? Chips from recognized suppliers such as Nichia, Cree, Showa Denko, Philips, Epistar, and OSRAM, are an indication of quality in LED products.
   
4. What color characteristics are specified? Color rendering index (CRI) is a measure of a light source's ability to reproduce light compared to a natural light source. Color correlated temperature describes the relative appearance of a light source (whether it appears more yellow or blue). IESNA LM-79-08 includes testing methods for both, and ENERGY STAR qualified LED products must meet minimum color-quality measurements.
   
5. What efficacy is specified? Efficacy is the ratio of light output (in lumens) to power input—measured in watts. ENERGY STAR qualified LED products must meet minimum efficacy requirements. Lighting Facts Label participants are required to test for efficacy.
   
6. What is included in the product warranty? Things to look for include, maximum number of diode failures, acceptable color change, power supply requirements, dimmer use/type, and maximum LEDs per circuit, which may or may not be specified in the warranty. The length of warranty is evidence of a manufacturer's confidence in product life.
   
7. What is the acceptable lumen output and depreciation? Lumen output depreciates over time, and according to the DOE, research has shown that occupants will accept gradual light reductions of up to 30% with little notice. Therefore, 70% of the initial light level may be a good threshold for useful life in general lighting applications. In achieving acceptable illumination for your application, also consider the directional nature of LED luminaires and outdoor light quality improvements. Compare the lumen output of the LED product with that of the lighting that is being retrofitted. The Lighting Facts label ensures that LED products meet your performance expectations.
   
8. What Light Loss Factor (LLF) should be applied? LLF refers to operating or environmental factors that interfere with light transmission. Be sure to take into account optical losses, ambient temperature, diode failures, lumen depreciation and dirt depreciation.
   
9. What dimming characteristics are required? Consider LED performance at dimming levels as well as dimming range and dimming method.
   
10. What impact will LED in-rush have on your lighting system? LED current in-rush may occur as frequently as every one-half cycle. This may affect how many LEDs can be ganged together on one dimming control, for instance.

Getting the answers to these questions will help you make a more informed purchasing decision and find the right product to fit your needs.

Energy Performance KPI

In many organisations, Energy KPI is always been carried by the Energy Manager and its subordinate. This KPI is usually refers to the overall energy performance of the organisation or plant. Common mistake occurred where the KPI is located at wrong managerial level and is not getting fully support from cross-sectional department.

In order to have an effective energy management system, energy performance KPI should be well established and cascaded at all level including the top management. The task in establishing the KPI would be on the energy manager. However he/she must ensure that the energy KPI is cascaded and each KPI in the end must support the overall energy efficiency objective of the company. The KPI owned by each department must be controllable within the department functions, and linked to the overall energy performance. The KPI is not necessarily only on the energy matters, but it could be for example on the activity on maintenance frequency for heat exchanger. Again, it depends on the jobs scope of the staff.

In establishing the energy KPI, Specific, Measureable, Achievable, Realistic or Practical and finally Timely-bound or in general S.M.A.R.T approach is applied. This approach will prevent the energy KPI be redundant to other staff or department. This will enable the top management to give a clear direction and objectives to the staff and department in achieving the company goal. The common mistake of the organization is by establishing energy KPI, but shared to all departments. This will provide a multi interpretations and unclear objective to the department, furthermore to the staff. Energy activity will become nobody business, nobody accountable for the activities. Therefore it is important that the KPI must be specific and linked to each department. The energy KPI after all must be linked to achieve the synergy result.

To support an effective KPI, energy index or specific energy index for example total energy consumed for that particular month over the production output (GJ or kWh/ tonnage), is the best total energy KPI. This will enable the management to measure the achievement and review the energy performance. This parameter will be the key monitoring parameter for the company. Some top management will carry energy KPI in monetary term or energy price. This is ok as long as this KPI is being linked with the real energy usage index. The danger of this energy price index is that the company may get confusion as the energy price fluctuating. We may see the energy index goes down by virtue of the energy price dropping, but in reality the energy consumption is status quo or may be increase.

It is advisable for the company to analyse its historical data when establishing the energy KPI parameter. This is to ensure that the KPI is achievable. Another alternative to establish achievable energy KPI is to refer to the best practices, design data or plant performance test data. For the newly setup factory or equipment, the design data is more likely to be used. Best practice data is the last resort to be used as best practices data may differ in terms of technology, operational mode and geographical location of that particular equipment.

Practicality of the KPI is also an important key factor for an effective energy KPI. Always establish energy KPI that is practical to be implemented and do not too ambitious. For example, to carry out steam trap survey or thermal infrared diagnostic for heat loss t steam system, it is more practical to do it once or twice a year a year as it involves cost of services and the work load of doing this exercise. Another example is boiler cleaning exercise, it is difficult to establish fix frequency of this activity as it depends on the operation schedule, it is sufficient to ensure it is cleaned each and every time during maintenance day.

Finally, KPI that has been set must have time bound to ensure its effectiveness, practicality, and its impacts to the operation. This time bound will be a platform to the management to review the KPI during the management review. On the energy KPI, the management must be aware that many factors influence the parameters for e.g. operation scenario, fuel prices, retrofitting activities, shutdown, start-up, plant expansion and etc. Therefore all these factors must be considered when reviewing the KPI.
