The spacious Feinberg Pavillion lobby, richly done in wood and earthtone hues, gives one a feelingof peace and serenity while greeting patients and visitors. (Lower right) Patient rooms are private,spacious and comfortable. Pleasant views are visible from the bed. All rooms are equipped with thelatest technology for the 21st Century.

inpatient care with 492 private roomsand 92 intensive care beds, and the 22-story Galter Pavilion for outpatient careand medical office space, connected byan 8-floor diagnostic and therapeuticcenter.

Over half the capital for the projectwas raised through investing and cuttingcosts, and the new facility is touted asone of the most modern, technologicallyadvanced medical complexes around.Architects for the new construction wereEllerbe Becket and Hellmuth Obata &Kassabaoum. And the ConstructionManagement for the project was a jointventure between Power Contracting &Engineering Corp. and CRSSConstructors.

The early stages of planning for thenew facility date back to 1987, when anadministrative evaluation concluded achange was needed to maintain apatients first commitment. The follow-

ing year, planning for the project began.1994 marked the groundbreaking, 1996marked the topping-out ceremony andMay 1, 1999 patients moved in.

Continuing with the theme PatientsFirst , Northwestern Memorial of fers ahost of patient-oriented features, likepull-out beds for family members stay-ing overnight, separate patient and pub-lic areas, a four-lane drive through dropoff and 2,000-space attached parking

garage, expanded Emergency Department facilities, bilingual sig-nage and a Health Learning Center open to patients and the publicoffering information on health conditions, drug and treatmentissues, alternative medicine and much more.

Northwestern Memorial also features a number of clinicaladvances. It is a leader in the development and practice of mini-mally invasive surgery, offers one of the most comprehensive treat-ment programs for early detection and treatment of ovarian cancer,is a world leader in neuroscience and imaging and is pioneeringnew treatments in cardiology.

Built on the site of the hospital s old parking garage, this con-struction project was gigantic and a challenge. Due to its proximityto Lake Michigan, a retention wall had to be constructed. After the100,000 sq.-ft. footprint was cleared, a 40-ft deep, 2-ft. thick slurry

Imagine how the air in your buildingmust feel if your mechanical systems

aren’t working right.

Air. It s one of our mostimportant resources, and it simportant that we keep itclean -- inside and out.

Your qualified mechanicalcontractor can help. Not onlycan we help your building befriendly to the environment,but we can also work toensure that the air on theinside is comfortable andflowing properly.

That s important to a buildingmanager or owner, becausefew things are more evidentthan poor environmental per-formance from your building smechanical systems.

Problems with these buildingsystems can lead to the threatof legal action.

At best, employees who are uncomfortable may not be asproductive as they could be.They may be too hot, or theair circulation may not be suit-able.

W orse yet, they may get sick.That costs their employersmoney, not only in medicalcosts, but in lost work time.

As a result, some tenants mayleave. And that costs anowner money. In fact, accord-ing to Building Owners andManagers AssociationInternational (BOMA), lack ofcomfort is now the primaryreason for tenants leavingtheir buildings.

The Bulb Eater BE-55-VRS from Air Cycle Corp. is the ONLY fluorescentlamp crushing unit on the market that can satisfy the needs of small or largescale lamp users. Able to transform more than 800 4’ lamps from piles ofboxes of fragile, dangerous, difficult to manage lamps into a compact 55-gallondrum. This stops the continued handling, and hazard liability, of whole lamps.

Air Cycle also provides a very low-cost, nation-wide drum removal service forrecycling that includes free replacement drums for each full one picked up.

The 55-VRS uses a tested three-stage filtering system that removes bothmercury laden dust and vapors. This is an "emissions controlled" crusher thatsatisfies EP A/OSHA requirements for on-site crushing. The filters are easilyand inexpensively replaced after very long service lives. The activated carboncharge is rated for millions of lamps, and chemically neutralizes the capturedmercury vapor into an inert mineral.

Stop worrying about fluorescent tube disposal. Call Air Cycle today to orderyour Bulb Eater. Buy, Lease, or use your credit card!

Northwestern MemorialHospital is setting a new, challeng-ing standard to the medical com-munity: The entire complex isHEPA (high efficiency particulateair filter) filtered. This is a uniquenew way to combat infection in amedical facility. By minimizing theamount of dust particles in the air,Northwestern Memorial has limitedthe transmission of contagiousgerms. An independent servicewas brought in to the facility to testthe level of dust in the air and haddifficulty finding a level!Northwestern Memorial has one ofthe lowest hospital-acquired infec-tion rates in the world.

There are a wide variety offans throughout the NorthwesternMemorial complex ranging in sizeup to 120 HP. Dual feed air han-dlers come in to the main duct andfeed 11 main supply fans. Theseare Joy Vane-Actuator fans. Theseare dual fans, so the actual num-ber of fans is 22. The dual feedfeature is nice because on non-extreme days, the engineers cando maintenance on 1/2 of the fanswithout interrupting service.

site. They feature a parallel andswitch gear system and can bestarted and stopped by theJohnson Metasys system. 85 ATSswitches are used by these gener-ators which also feature load opti-mization. In case of outage, theycan run off of 2-3 generators basedon the load required. T otal capacity

for all five generators is 10 millionwatts.

All wall barriers inNorthwestern Memorial have firestop that goes all the way up tothe next floor. 4,000 smoke detec-tors are also spread throughoutthe complex, which is fully sprin-klered.

Northwestern Memorial hasgone to great lengths to provideefficient transportation betweenthe hospital floors as well as priva-cy for patients. To facilitate this theelevators are separated into fourcategories: Patient T ransport,Staff, Service and Public. Thesedesignations are strictly enforcedand transportation is smooth. Allelevators in the complex can beprogrammed from the JohnsonMetasys system.

Going through the basic sys-tems found in NorthwesternMemorial s campus doesn t tell thewhole story. In addition to boilersand chillers and air handlers are avariety of highly specialized equip-ment for use in medicine. A list ofsome of the major pieces includesa non-potable water system forsterilizers and a medical air sys-tem for patient rooms whichincludes a medical vacuum sys-tem, lab air and lab vacuum.

Part of NorthwesternMemorial s success in minimizinghospital infections is no doubt dueto the fact that every patient roomhas its own sink to combat thespread of bacteria. Another nicefeature is the presence of oxygen,vacuum and medical air on bothsides of every bed. This allowsany bed to immediately be con-verted to an Intensive Care Unit.The beds in the complex alsoincorporate new technology, posi-tioning and adjusting by sensoraccording to body type.

There are many ways such anassemblage can be controlled anddispatched. However, a superviso-ry control system has not yet beenbuilt. The best way to test a con-trol system is to build it and field-test it in a utility application of dis-tributed generation at a customerlocation. Building, testing, andevaluating control options will pro-vide data and experience that willhelp other users of the technology.

This project will fund a shareof the purchase, operation, andtesting of a one-megawatt five-pack (five each 200 kW PAFCunits). The total cost of this projectis $5,650,000 apportionedbetween the following parties:DOE Buy Down Funds: $1 million;

Chugach up to $1.2 million plusfuel and operations and mainte-nance costs; USPS $1 million;NRECA-CRN/EPRI $750,000.There is also cost sharing from theU.S. Army ConstructionEngineering Research Laboratoryand the manufacturer, ONSI, in an

additional amount of approximate-ly $1.7 million. Most of their costsharing is focused on designingand building components for a SiteManagement System (SMS). TheSMS will coordinate transferbetween the grid-connect and grid-independent load share operatingmodes, and provide the interfacecommunication capabilities for

control of the multi-unit installation.Its development ef fort is beingdone in stages. The first stagewas construction of a SMS enclo-sure that includes a global by-pass.

The installation is designed tomeet the US Postal Service s(USPS) peak electrical load fromthe fuel cells and provide heat inexcess of its thermal require-ments. The installation will coveran area 75-feet x 139-feet on theeast (back) side of the USPS facil-ity. The relatively large footprint ofthe installation was selectedbecause ample land was availableand it allows Chugach to minimizeinstallation and snow removal-related maintenance costs. Thisproject s load sharing and seam-less transfer features requiredredesign of the inverter controlsystem in each of the fuel cells.These components were installedin the fuel cells prior to shipping.

The research and develop-ment tasks includes the purchaseof fuel cells designed to work withthe new control system andChugach participation in thedesign of the supervisory controlsystem.

Design work of the superviso-ry control system includes thedevelopment of the physical lay-out, control and functions, operatorinterface and utility system inter-face Supervisory Control and DataAcquisition (SCADA). This willrequire a significant effort by beingpresent to work with vendors, pro-grammers, and suppliers of com-ponents and systems in order toensure proper interface and opera-tion.

Chugach will prepare an inter-im project report after commissiontesting of the installation. Theinstallation will include five PC25Model C Fuel Cell Power Plantswith SMS controller and equip-ment interfaces with the customerload and the Chugach grid.Included in the interim report willbe a description of Chugach s s i te

fessor of biostatistics; and Dr.Dana Loomis, associate professorof epidemiology, all at the UNC-CH School of Public Health.Statistical programmer Dr. RobertC. Kleckner also contributed to theproject.

We believe this work isimportant because suicide is theeighth leading cause of death inthe United States, and many peo-ple in this country are exposed toelectromagnetic fields, vanW ijngaarden said. While thesefindings definitely do not proveEMFs cause suicide, they do indi-cate more research needs to bedone on the effects of exposure ondepression and suicide.

A large and detailed study of thepossible link between exposure tolow frequency electromagneticfields (EMFs) and suicide amongelectric utility workers has uncov-

ered what appears to be a distinctassociation.

Electricians working for fiveU.S. power companies faced twicethe expected risk of suicide, whilelineman faced one and a halftimes the expected risk, accordingto the University of North Carolinaat Chapel Hill study. Suicidesamong power plant operatorsoccurred at a rate slightly lowerthan expected, researchers found.

Younger people appeared tobe at greater risk of suicide thanolder ones, and higher, morerecent exposures also seemed toboost the chances that workersmight take their own lives.

WORKER SUICIDECONTINUED FROM PAGE 21

Using employment files, deathcertificates and other records, vanW ijngaarden and colleagues found536 suicides among current or for-mer electric utility workers in thegroup between 1950 and 1986and identified 5,348 non-suicidesof the same race and age to serveas controls. Researchers also ana-lyzed various job titles and dutiesand estimated occupational expo-sures to EMFs based on devicesrandomly selected workers wore tomonitor exposures.

Why low frequency electro-magnetic fields might contribute tosuicide among chronicallyexposed workers is not known,van W injgaarden said.

One biologically plausibleexplanation is that EMFs depressproduction of melatonin, a hor-mone that s important for sleep

and mood, he said. Decreases inmelatonin can lead to depression,which in turn can lead to suicide.

Rats subjected to electromag-netic fields showed altered produc-tion and excretion of the hormonebut comparable data on humans islimited and inconclusive, the scien-tists said. The possibility suggest-

ed by the new findings that EMFscould af fect young workers morethan older ones is entirely new, headded.

The Electric Power ResearchInstitute of Palo Alto, Calif., sup-ported the study. Cooperatingelectric utility companies were

Carolina Power and Light, PacificGas and Electric, PECO EnergyCo., T ennessee V alley Authorityand V irginia Electric Power Co.

Van Wijngaarden and col-leagues did the new studybecause other work in the early1980s found indications of anassociation between EMFs andsuicide, but later studies could notreplicate those findings.

W omen were excludedbecause at the time they rarelyworked as electricians, linemen orpower plant operators.Researchers could not control forpast mental health problems,addictions and family disturbancessuch as divorce since such infor-mation was not available.

While these findingsdo not prove it,

they do indicate moreresearch needs to

be done onthe ef fects of EMFs.

The AFSPC is the largest UPSuser within the entire U.S. AirForce, and purchases about $2million worth of lead-acid backupbatteries a year for its 45 sites

worldwide. Inmost of thesecommand loca-tions, the need forreliable power isabsolutely essen-

tial for some activities; even thesmallest fraction of a second dis-ruption can put vital national secu-rity operations at a risk.

The problem stems from powerquality, which is always a concernin many overseas AFSPC loca-tions. Even in Colorado Springs,lightning strikes cause frequent,short power outages, of less thanone second or power glitches, par-ticularly during certain seasons.These small glitches can compro-

mise the overall reliability of thesystem by unnecessarily exercis-ing the battery, said MSgt Bills of

The flywheel was designed andmanufactured by Active Powerand integrated with Powerware sPowerware 300 UPS. The installa-tion is located at Peterson AFB.

One of the reasons AFSPCchose the Powerware-ActivePower flywheel was its small size,noted Jim Balthazar, ActivePower s vice president of market-ing. The 480 kW system dis-places only 10 square feet, com-pared with the 100 s of square feetof batteries required to provide thesame level of power. The typicalUPS backup string configured byAFSPC consists of 188 to 240 bat-tery cells at 2.2 volts per cell, andtakes up a lot of room, Balthazaradded.CONTINUED ON PAGE 24

FLYWHEEL ENERGY STO R A G ECONTINUED FROM PAGE 23

Under a recently announcedinitiative, Powerware Corporationand Active Power have teamed toprovide the most reliable end-to-end power solutions available. Thegoal of the Strategic PowerPartners Program is guaranteedsystem availability, and it provides

customers like AFSPC the oppor-tunity to create a power systemspecifically tailored to their needs,Ascolese said.

The purpose of the flywheel inAFSPC s UPS installation is toabsorb the nuisance hits and pre-vent the backup batteries from dis-charging during most power glitch-es. When the flywheel senses a

drop in voltage or a completepower outage, it instantly begins togenerate power at its programmedvoltage level. This action keeps allcomputers and other electricallypowered systems and machinesoperating smoothly and avoids acostly cycling of the backup batter-ies.

For the much less frequentpower outages lasting longer thanone minute, the standby generatortakes over supplying electricity tovital guidance systems until powereither can be restored from theutility grid or the mission can behanded off successfully to a diff er-ent AFSPC location. The batteriesare for added redundant backup.

The system was put in place inDecember of 1998. AFSPC is socertain the flywheels will show amarked improvement in preventingbattery degradation that it alreadyis planning other flywheel installa-tions.

Recent studies have indicatedthat resident goose populationexceeds one million in theMidwestern Mississippi Flywayand is increasing at a rate of six

percent ayear. Canadageese repro-duce at highlevels and

have a high survival rate due toideal breeding conditions, lack ofpredators, and an abundance ofpreferred habitats provided by cur-rent landscaping techniques. Also,the lack of waterfowl hunting insuburban locations, coupled withfree food handouts by humans,are causing the goose populationto increasingly conflict with humanactivities on both public and pri-vate property.

Many short-term managementstrategies have provided tempo-rary relief, but the Service hasfinally agreed that new long-termapproaches will be needed.

The U.S. Fish and W ildlife Servicehas agreed that wild goose popu-lations in the Midwest are posingthreats to health, human safetyand property. The Service is in the

process of preparing anEnvironmental Impact Statement(EIS) under the authority of theMigratory Bird T reaty Act.

Many people have expressedconcerns about the health risk tothe general public and propertyposed by exposure to Canadageese droppings. Elected off icialsat all levels have been asked toprotect our citizens as well as theyprotect the Canada geese. TheService scheduled a series ofmeetings nationwide encouragingpublic participation. Locally, onewas held in Palatine, IL lastFebruary.

and electric generation sectors,key markets for natural gas.

The study concludes that totalcoal demand by electric genera-tion and industrial customers is

expected toincrease slowlyfrom 980 milliontons in 1998 to1,123 million tons

by 2015. After 2015, coal use isprojected to decline to 1,101 mil-lion tons by 2020, due to theimpact of stricter environmentalregulations. The study also proj-ects that the average real (1999$)FOB mine-mouth coal price willdecline over the projection period.Real FOB price is projected todecline from $15.79 to $12.62 perton between 1998 and 2020. Thedecline is due to continuedimprovement in productivity, l ack-luster demand growth, and anincrease in the market share oflow-cost W estern coals.

Despite the fact that U.S. coal pro-duction increased during 1998,recent events have led many tobelieve that the coal industry isfacing a dif ficult period. Exports

have fallen, natural gas hasbecome the fuel of choice foralmost all new generating units,and the Environmental ProtectionAgency has launched numerousinitiatives that will raise the cost ofusing coal.

A two-volume study, CoalDemand and Price Projection(GRI-00/0019.1 and GRI-00/0019.2), recently completed byGRI and Hill & Associates, Inc. ofAnnapolis, Md., examines thesechallenges in detail. It features anextensive analysis of the competi-tiveness of coal in the industrial

Increasingly Difficult CompetitiveSituation For Coal

The key to the continued via-bility of coal as a fuel option hasbeen productivity improvement,said Kathy Nice, GRI principalenergy analyst. Coal-mine pro-ductivity has increased steadilysince 1978, at 6.5 percent peryear. While some in the coalindustry believe that productivityimprovement will slow sharply andwill no longer be able to off setinflation, there has been virtuallyno evidence to support this viewover the past 20 years.Improvements in technology andcompetitive market pressures areexpected to continue to drive pro-ductivity higher.

Among the study s other keyfindings are:The availability of adequate coalsupplies depends on the timelyopening of new mines by produc-ers. The last series of capacityexpansions led to the developmentCONTINUED ON PAGE 32

of surplus deliverability and lowprices. Given this experience, pro-ducers may be unwilling to contin-ue to expand capacity ahead ofdemand requirements. Future sup-ply expansions are likely to becompleted in a more measuredfashion than in the past.

In the near term, W estern low-sulfur coal, primarily from thePower River Basin, is projected toincrease its share of total U.S.coal production from 52 percent in1998 to over 55 percent by 2005at the expense of Eastern coalsupplies. Post-2005, Eastern coalis expected to regain some marketshare as more scrubbers are built,allowing increased consumption ofhigher-sulfur coal from the NorthAppalachia and Illinois Basin.

The steps involved with work-ing through major rail consolida-

tions in the Western and EasternU.S. have created some turmoil intransportation markets in recentyears. In the short term, theseproblems have lead to growingdissatisfaction with rail service.However, these mergers have alsohelped to keep transportationcosts stable. There have been nosignificant increases in overall railrates since the early 1980s.These productivity improvementsare expected to continue and, as aresult, rail rates are not anticipatedto increase over the projectionperiod, putting no upward pressureon delivered coal prices.

The wild card in coal marketswill continue to be environmentalregulation. Environmental regula-tions are expected to require thecoal industry to further reduce sul-fur dioxide (SO 2), nitrogen oxide(NOx), and fine particulate emis-sions. Calls for the regulation of

mercury emissions (and othertrace toxic materials) are expectedto grow and, ultimately, there arelikely to be limits on carbon emis-sions. While the final impacts ofthe anticipated regulations areunknown, they will put downwardpressure on coal prices becausecapital investments will berequired for coal to remain a viablefuel option.

Demand for U.S. coal exportsgrew sharply starting in the late1970s. However, export demandfor coal has begun to decline inrecent years due to growing envi-ronmental concerns in Europe,weak economic growth in Asia,and new low-cost internationalcompetitors. The decline in U.S.coal exports is expected to persist.Exports are projected to declinedramatically, from 78 to only 24million tons between 1998 and2020.

New Eye-Trek GlassesCompares V iew To That Of A52 Screen

The new Eye-Trek glasses intro-duced by Olympus America Inc.Industrial Products Group (IPG)allow users to view remote visualinspection images on a displaythat is worn like a pair of goggles.According to Olympus, Eye-Trekprovides video images comparableto those seen on a 52 screen.

Leslie Boegel, IPG s AssistantMarketing CommunicationsManager, explained that Eye-Trekimages are four times brighterthan those produced by conven-tional concave mirror optics, so itcan be used even in brightly litsurroundings and in bright sun-light. The See-Around-Designassures that you never loseawareness of your surroundings.

Eye-T rek incorporates a free-shaped prism, a highly developed

sustainable brightness levels fourtimes those of standard concavemirror optics. At the same time,advanced optical technology cor-rected various aberrations, suchas unevenness in the image.Other aberrations were alsoreduced, resulting in clear, high-resolution images over the entirescreen.

Eye-T rek weighs under 4ounces, can be worn over eye-glasses, and adjusts to comfort-ably fit individual users. It is com-patible with Olympus portablevideo inspection systems.

How to meet the requirementsof hazardous material regulations How to protect themselves, the

public, and the environment frompotential hazards while they aretransporting hazardous materials.

A mistake transporting haz-ardous materials can be surpris-ingly easy to make. Adding anextra can of gasoline to a servicetruck already carrying two gascylinders, or delivering two five-gallon containers of product to acustomer could put the sales orservice person in violation of haz-ardous material transport regula-tions.

The results of such a mistakecan be serious. Fines of up to$27,500 per day and up to fiveyears of imprisonment can beapplied with personal responsibili-ty. That means the sales or serv-ice professional is personallyresponsible for the fine. It cannotbe paid by the employer. To pro-

tect themselves, the public, andthe environment, it is essential thatsales and service professionalsknow and understand the materialpresented in Hazardous Materialsfor Field Service: Materials ofTrade.
