ering both the significance and benefits of short-term diagnostic monitoring for plant maintenance and expansion.. We will discuss typical monitoring points and show several examples of data-logging results. In part two of this article we will discuss things to consider when choosing a portable data logging system and point out things to be cautious about.

What are Energy Monitoring Data Loggers?

TRACKING FACILITY OPERATIONAL PROBLEMS that have an effect

on energy consumption is quite often time consuming and expensive. However, hidden maintenance complications that often are not noticeable affect both operational and environmental quality and can be the reason for higher than needed energy costs and more frequent equipment repair and replacement. There are many instruments available to the engineer and maintenance staff to tackle finding these problems and costs. A work horse up to the task is the portable data logger. They are extremely flexible and can save a significant amount of time troubleshooting without the need for an operator to be constantly attending to it. They can detect unseen problems that may be costing many thousands of dollars annually in wasted energy and untimely equipment failures. 6

Whether for troubleshooting a known problem or proactively seeking opportunities to optimize power distribution systems, portable data loggers and their accessories should be as common in building maintenance technicians’ arsenal of tools as a multimeter or thermometer. Energy service industry professionals are making good use of data logging equipment and are discov-

Portable data loggers are compact, lightweight, battery or AC powered, electronic monitoring instruments used for collecting data without the need for operator intervention or presence. They can be installed in load center panels or around the facility without difficulty and removed as easily without the need to shut down the plant or office building first. See figure 1. They are capable of storing tens of thousands of readings to several million readings and can be programmed to collect data on a sub cycle basis or store averages at user programmable aggregation periods. They are available with a display or blind (no display) and can transmit their recorded data locally or remotely. Data loggers can gather electrical data such as amperage, voltage, power and energy as well as temperature, flow, pressure, event and other data associated with facility maintenance and troubleshooting. The data loggers with the most versatile application employ separate sensors for each parameter to be recorded. They also provide the ability to automatically recognize those sensors and set the scale and measurement parameters accordingly. They come in single and multi-channel models. Multi-channel data loggers Continued on page 8

can collect data for several input types simultaneously. For example, a six or eight channel logger may be set up to collect measurements from three or four voltage and three or four current inputs providing the ability to monitor three-phase power systems. Mathematical capabilities provide the ability to calculate power and energy, as well as the cost associated with that energy consumption. Remote access to the data collection process from the office or at remote locations with wireless or Internet access provides the ability to track several consumption points around the facility or multiple facilities without the expense of travel to retrieve the data. Energy management systems in place today provide logging however, they are often installed with only a limited amount of memory and will only capture a summary data. They tend to be permanently installed devices and will only monitor data from one point in the facility making it difficult to troubleshoot problems around the facility. Portable data loggers overcome these limitations by providing the ability to locate problems and provide information 8

vital to improving energy consumption. Data analysis software provides a picture of the monitored data over time and the ability to download to a computer for analysis. Most software is capable of displaying in line graphs often referred to as X/T plots with time on the X axis and amplitude on the Y axis as shown in figure 2. When evaluating harmonic data, it is often easier to view it in a bar graph format rather than a line graph. The ability to look at several channels of data on the same graph such as three voltage phases or three current phases provides a convenient way to easily troubleshoot power systems. Also, the ability to zoom in and analyze smaller time sections or compare this week’s data to last weeks is an invaluable tool. In the energy game, you can’t manage what you can’t measure. Energy consumption takes place over time and therefore should be recorded over time. Portable energy monitoring data loggers increase the technician’ ability to manage energy by providing the tool to measure and analyze that energy over time.

Energy waste is an ongoing issue and is often undetected. Installing an energy logger on equipment that uses large amounts of power or in electrical panels can provide clear and revealing information about energy use when the facility is in a non-operating state. There is a tremendous opportunity to save on energy costs by reviewing this information. Energy managers usually track monthly utility bills to understand a building’s energy use and demand. This helps managers understand when energy use or demand has increased or decreased. Although good energy reviewing practices will sometimes indicate that a problem may exist, it does not always help in understanding where, at what time, and why the increases are occurring or whether they are correct. The use of portable data loggers along with energy reviewing practices provides the missing information necessary to properly evaluate energy problems. Energy loggers can help identify and document when in Continued on page 12 time and where energy

alone is not always enough. No matter how well technicians maintain equipment, if it operates inefficiently, or more often than needed, energy waste will occur. The cost of not paying attention to operational issues along with the maintenance issues can be significant. Many studies performed over the past several years indicate that most energy savings opportunities are operational in nature. Energy savings as much as twenty to twenty five percent of the annual energy cost can be realized through low-cost improvements, with operating improvements accounting for a good portion of the savings. Internal facility staff and maintenance personnel and service contractors can assist the building management more effectively by addressing operational issues as well as equipment maintenance issues.

Energy managers can find it difficult to propose changes in equipment and/or procedures to upper management that require investment because of the lack of data to support their recommendations. Data loggers and their analysis software provide energy managers a clear, documented way to graphically present specific data on activities in the facility that increase or decrease energy use. This clear information based on measured data can help energy document the need for operational changes and procurement of more energy efficient machinery. They also provide the ability to record and document the savings by monitoring the energy usage after the changes have been made and by comparing the energy usage before and after.

Periodically, monitoring critical machinery and high energy consuming building equipment to ensure proper operation should be as important as periodically performing maintenance other tasks such as cleaning coils, lubricating motors or changing filters. Portable data loggers allow facility staff and maintenance contractors the capability to expand their preventative maintenance programs to also include pre-emptive operation tasks. Next month we will deal with the selection process for determining the right data logger for the task at hand. We will review the process of selecting the number of channels needed, the right sensors, sampling and storage mechanisms, display and power requirements, communication techniques and data review and analysis software.

CASE STUDY • Residential — The Roosevelt Hotel

Using Advanced Dimming Controls to Eliminate LED Light Flicker and Create Perfect Hotel Ambiance IN THE HOTEL BUSINESS, creating the perfect ambiance is key. It helps showcase the look, feel and mood that hotel guests come to expect when they enter through the front doors. This poses unique challenges for electrical contractors and designers, as is evident in a recent lighting retrofit project completed by The Roosevelt Hotel in Seattle, Washington. Built in 1929, The Roosevelt is a handsomely restored hotel located in the heart of a number of downtown Seattle attractions. The hotel prides itself on setting the ideal mood for its guests, and embarked on an upgrade for the lighting fixtures in the lobby area with state-of-the-art energy ef-

ficient lighting to help achieve that. To achieve the targeted lighting levels and colors, The Roosevelt decided upon LED lighting, based on recent technological improvements in product design. When used with a dimming device, LED lamps would help transform the lobby area with perfect colors and aesthetics unable to be achieved with the standard incandescent lighting used for nearly a century. LED lighting not only sets the right mood, but since lobby lights require a 24-hour burn, also provides the hotel with savings on its utility costs. Early attempts at using dimming devices with the new LED lighting resulted in low-end flickering when the lamps were in dimmed to lower light levels. This was a very prominent problem for both guests entering the hotel and staff who could visibly notice the issue. The ideal ambiance that the hotel had worked so hard to be known for was not being recognized. Patrick Hughes, chief engineer at The Roosevelt, in looking for alternative solutions that would eliminate the low-end flickering issues, turned to Graybar, a specialized distributor of high-quality components, equipment and materials for the electrical and telecommunications industries. The alternative solution would have to not only eliminate the low-end flickering problem, but have to be an easy, straightforward solution that didn’t require extensive renovation to the hotel’s lobby – pulling wires, patching walls and repainting. In discussing the issues, Jim Edwards from Graybar Seattle, recommended Leviton’s Universal Dimmer, a preferred solution that eliminates flickering issues especially when dimming lighting banks that contain multiple LED lamps. Edwards has worked with Leviton products on a near-daily basis, and after seeing firsthand the capabilities that the product Continued on page 16 offered, knew that the

CASE STUDY • Residential — The Roosevelt Hotel Universal Dimmer would alleviate the problems The Roosevelt was having with other options. Since the Universal Dimmer works with both two- and three-wire installations, the solution was ideal for The Roosevelt’s existing residential wiring infrastructure that was built without a neutral wire at the switch box. This allowed for an ease of installation since contractors could install the devices without pulling a neutral wire. Through rigorous testing processes, Leviton ensured that its Universal Dimmer would be the ideal solution for a wide range of energy efficient lamps – both dimmable LED and dimmable CFL – and eliminate the low-end flickering often found with other solutions. Leviton’s Universal Dimmer is the ideal solution for eliminating a number of issues when dimming energy efficient lamps, including flickering or fluttering of the lamp – as was the case at The Roosevelt – as well as reduced dimming range

and inconsistent performance based on the number and assortment of lamps being controlled by one incandescent dimmer. It gives contractors, distributors and retailers the ability to offer a single lighting control capable of properly dimming nextgeneration lighting sources while remaining backwards compatible with current lamps. In total, The Roosevelt installed 12 Universal Dimmers – six in the public

lobby space, and since the devices worked so well, six more were installed in management offices to enable proper dimming control behind the scenes while individuals were working. Hughes noted that since the completed installation of Leviton’s Universal Dimmers in the lobby, everyone has been pleased. In the hospitality industry, guest satisfaction is the ultimate goal, and if something is amiss, they’ll notice. Roosevelt guests have commented on the updated mood of the hotel, and noted that improved lighting has made colors crisp and clean, even at low levels. “We have been extremely pleased with the end result that Leviton’s Universal Dimmers provided in helping create the ambiance that we here at The Roosevelt Hotel want our guests to receive,” explained Hughes. “Not only has the overall look and feel of the hotel improved, but we have been able to see utility costs go down significantly, which is a major plus for any business owner.” ❏

Saving Time & Money with Remote Power Management

By Bill Allen, Director of Marketing, and Karren Hodge, Marketing Database Specialist

WHENEVER A DEVICE FAILS, the most proven method is to cycle power or reboot. This can be challenging if the device is not easily accessed or the device is located in another state. It’s simple to cycle power off and on when you can easily get to a device that’s locked up. However, when it’s in an inconvenient location, the problem is magnified. Remote power management systems are designed to solve the problem of equipment lock-ups and reduce downtime. With an RPM and a static IP address, IT, security and telecom managers can reboot devices utilizing a standard web browser and a password. Locked-up devices can be reset from a desktop pc, laptop, smart phone or tablet. Regardless of what causes downtime and/or lock-ups, it is essential to keep vital applications and equipment

It pays to invest in solutions such as Remote Power Management products to aid in the support of mission critical devices. When equipment fails, it costs businesses money. Achieving the maximum amount of uptime is critical to the health of any company who relies on mission critical devices such as data centers for business critical services. Data centers have become a business asset and a core satisfaction. As these data center operaof business performance tions increase, so do the financial and inand customer tangible costs of downtime. When equipment fails, it costs businesses not only monetarily, but it affects their reputation. Ponemon Institute’s “National Survey on Data Center Outages” says that 95% of companies experience an unplanned downtime event. 60% of these companies rely on their data center to generate revenue or support e-commerce activity, and out of these, less than 35% believe they have the system in place to maximize the availability of uptime. The cost of downtime can be devastating to a business. According to a survey performed by CA Technologies, more than $26.5 billion in revenue is lost each year from downtime which means each business is losing $150,000 annually. The survey also revealed that outages can damage a company’s reputation, staff morale, and customer loyalty. According to the same survey, businesses suffer from 14 hours of IT downtime per year and an average of 18% of Continued on page 20 these companies

35 Years of Commitment to the Lighting Distributor The National Association of Independent Lighting Distributors (NAILD) was founded in 1977 by a small group of distributors who wanted to join forces and promote the Independent Lighting Distributor. Today there are over 100 active members who recognize the great value each of their organizations receives for their investment. The membership now consists of Lighting Distributors, full-line Electrical Distributors with Lighting Divisions and Manufacturers. In 2011 NAILD created an Associate Member category. Qualified Associate Members are organizations involved in the lighting industry that are not distributors or manufacturers, but whose inclusion in the membership would benefit both NAILD and the Associate Member. Typical candidates for Associate Membership would be Manufacturers Reps, Lighting Maintenance Contractors or Consultants. The 2012 NAILD Conference celebrated 35 years of promoting independent lighting distributors throughout the United States and Canada. It was held at the PGA National Resort in Palm Beach Gardens, FL and included many retired members who returned to renew old friendships and learn about the ever-changing technologies available to lighting distributors. The conference continued its tradition of Education, Networking and Technology. The anniversary dinner featured a slide show with 35 years of conference photos including golf tournaments, networking sessions, keynote addresses and hospitality suite frivolity. Keeping in line with the era in which NAILD was created, the music of the 70’s was prominent throughout the evening. Over the past 35 years NAILD has grown beyond networking to serve the needs of its members in many areas. The main objectives of NAILD are: • Increase the effectiveness and profitability of the lighting distributor through educational programs and networking with like-minded members. • Develop marketing strategies and programs to improve membership awareness and to gain participation in supplier marketing programs. • Promote the importance and benefits of effective and efficient lighting.

The LS I program starts with a basic philosophy that the student should take personal responsibility for their own learning. It was designed to increase the student’s confidence and competence in light and lighting. The class is completed online within 6 months at a pace that the student is comfortable with. A Coach is available to each student to guide them through the process. The course consists of: • Ten online modules that are available on-demand. • Workbook activities for each module designed to reinforce the content of the modules. • Hands-on exercises that allow the student to practice what they have learned. • Module quizzes – ten questions that help the student ensure retention of the material. • Final Exam – a two part review of what the student now understands about light and lighting. The exam consists of multiple choice questions and case studies. • The ten modules cover all of the basics of lighting to help grow your business. ■ Module 1 Lighting Overview ■ Module 2 Introduction to Sources ■ Module 3 Light and Color ■ Module 4 How we see ■ Module 5 Filament Sources ■ Module 6 Fluorescent Sources ■ Module 7 HID Sources ■ Module 8 Ballasts ■ Module 9 Luminaires and Controls ■ Module 10 Solid State Lighting – LED Lamps

For more advanced Lighting Education, NAILD has also created the LS II program. NAILD LS II is available to all individuals who have successfully completed the NAILD LS I course. The focus of LS I is on the basics of lighting and technology. LS II focuses on how to apply those lighting principles at your customer’s facilities. NAILD LS II is a tool to help move you and your staff from the role of “product provider” to the role of “solution provider” In addition to the online training programs, NAILD also offers many other educational opportunities to its members. The annual conference includes several educational track sessions covering lighting technologies as well as insights into how to better run your business. There is a monthly program called “A Light Lunch” which is an online, hour long discussion group.

Education

Networking

The educational opportunities provided by NAILD have become the primary focus of the membership. In recent years NAILD has developed the LS I Education Program to provide basic lighting training for the members and their staff. NAILD is now offering this extraordinary program to non-members. LS I is a ten module program that was designed to quickly educate employees on the basic concepts of lighting. Distributors, Manufacturers Reps, Lighting Maintenance Contractors and Property Managers can all benefit from training their Customer Service and Warehouse staff, as well as new sales or maintenance employees that do not have a lighting background.

NAILD was created 35 years ago to give Lighting Distributors the opportunity to network with colleagues from throughout the country and share ideas and experiences. Networking remains a major aspect of NAILD membership. The primary forum for networking is the annual Conference. Each year NAILD selects a premier resort property to bring the membership together for four days of Networking, training sessions and recreation. Since many of the members are manufacturing companies that provide products or services to distributor members, the conference provides a rare opportunity for distributors to spend time with Continued on page 26

Industry NEWS

Immedion and Toshiba are a Reliable Team TOSHIBA’S G9000 UNINTERRUPTIBLE POWER SYSTEMS

are a favorite of many colocation service providers due to its industryleading efficiency, small footprint, attractive design, and superior reliability. Among them is Immedion, one of the country’s premier colo providers, based in South Carolina. Rob Moser, Co-founder and COO of Immedion, sums up his company’s mission. “Since 2007, Immedion has helped local companies keep their data, systems, and applications safe, secure, and always accessible. As South Carolina’s first and premier data center service provider, Immedion’s objective is to keep customer business-critical data and applications available 100% of the time 24x7x365.” Immedion has four data centers in South Carolina at press time. Their commitment to data security, budget consciousness and an infrastructure management plan that maximizes uptime led them to evaluate and eventually select the Toshiba G9000 as the sole UPS in their Greenville and Columbia, SC properties. Over time, Moser and his team were impressed by the G9000s that they installed in their earlier data centers, but still gave the competition a fair shot at their business when planning their more recent locations. In the end, the G9000 was their choice again. “In 2012, Immedion expanded our Asheville, NC data center, and

built a new data center in Charleston, SC as well”, Moser states. “As part of these expansion efforts, Immedion evaluated UPS systems and technologies from all providers; our criteria were reliability, efficiency, price, and partnership. Once again, we chose the Toshiba G9000 Series UPS. Given the proven performance Continued on page 30

Industry NEWS Immedion and Toshiba... Continued from page 28

demonstrated by the Toshiba systems installed in our Greenville and Columbia, SC data centers, Toshiba was the correct choice for Immedion’s expansion. This further developed Immedion’s already strong partnership with Toshiba Systems, who now provides UPS systems at all four Immedion data centers.” ABOUT THE TOSHIBA G9000 The G9000 series UPS is a full-IGBT UPS designed specifically for data center loads. It is available in capacities of 80, 100, 160, 225, 300, 500, and 750 kVA and comes with an industry-leading threeyear onsite warranty. It is designed for stand-alone or parallel use in up to eight-unit configurations without requiring the use of special intelligence in the output switchgear cabinet. Using the new Toshiba IGBT technology in the rectifier/converter, DC/DC chopper, and the inverter sections of the UPS, the G9000's double-conversion topology provides an AC/DC/AC efficiency of up to 97% at loads from 50% to 100%. Even at 20% loading, the efficiency remains greater than 96%. This is 10% to 20% better than current industry systems, making the G9000 excellent for N+1 parallel systems where loads are typically 30-40%. Toshiba International Corporation (TIC) is a Toshiba America Inc. (TAI) Group Company, a wholly owned subsidiary of Toshiba Corporation. TIC is headquartered in Houston, TX, and employs approximately 1,250 people.
