US EPA CampusResearch Triangle Park, North Carolina

Highlighted Technology: Alternative Transportation Support

Owner/Contact: US Environmental Protection AgencyTelephone: (919) 541-0249

Technical Strategies:

The new EPA Campus at Research Triangle Park has taken an integrated approach to transportation planning ,including a heavy emphasis on alternative means of commuting to single occupant vehicles.

Bus Transit � EPA has arranged for buses from the Triangle Transit Authority (TTA) and the Durham AreaTransit Authority (DATA) to stop at the front door of the main facility, as well as at other convenient points onthe campus, including the neighboring facility of the National Institute of Environmental Health Sciences. TheAgency�s transit subsidy program pays $65 per month to cover employee bus fare.

Bikes � Roadways will be striped with bike lanes, bike racks are under cover in the parking decks adjacent tobuilding entrances, and showers with lockers are located nearby.

Car and Van Pools � Priority parking spaces will be provided near the building entrances to encourage car and vanpools, and the Agency pays the monthly cost of van pool fare. EPA offers in-house car pool matching on itsemployee web site.

Parking Plan � With its heavy emphasis on alternative transportation, EPA has reduced total parking spaces forthe campus. 1,800 spaces serve 2,000 employees plus visitors, which is far less than is typical in this region.

Other Steps to Reduce Driving � EPA also has programs to decrease the overall need to drive. A �flexiplace�work at home option is available to many employees, depending on their job functions. The campus includesan on-site child care center and nursing mother facilities. An on-site food court, ATM machines, mail center, andconvenience store complete with dry cleaning drop-off and pick-up also help reduce need for off-site trips duringthe day.

With a rise of 60 feet from its lake slope edge to its hilltop, the sloping site presented a challenge todesigners. But by curving around and hugging the side of the hill, the main facility on the EPAcampus minimized the need for excavation and clearing. Tall, mature forests have been kept stand-ing as close as 50 feet to the building.

The site development plan for the new EPA Campus was initially guided by a 1970 master plan bythe U.S. Public Health Service. The plan specified four-lane boulevards with medians and wideclearings for underground utilities outside both sides of the roads. Vast areas of surface parking wereto be located remotely from the buildings, requiring additional clearing for walkways. EPA re-evaluated the master plan and chose an approach that saved about 25 acres of forest.

Roadways � Backed by a professional traffic analysis, EPA changed the four-lane and median systemto a two-lane road. Wider areas were maintained at public road intersections to promote swift entryand exit at rush hours. Electrical and communications lines were placed under the pavement tofurther reduce clearing to the minimal required to construct the roadways.

Parking � Several acres of clearing were prevented by placing half of all parking spaces in decks. Be-cause of the site�s sloping terrain, the costs of retaining walls and drainage systems for all surfaceparking would have nearly equaled the cost of the decks, and the parking service to employees isvastly improved, since these spaces are much closer to the buildings.

Highlighted Techology: Stormwater Management System

Owner/Contact: Eckerd Drugs/JDH Capital (management firm)

Telephone: (704) 357-1220 x 209

Technical Strategies: Sand filters are a two-tiered system used to remove solids andreduce pollutants as stormwater exits developed areas. The firstchamber removes debris while the second chamber, which isthe sand filter, removes pollutants from the stormwater. Main-tenance includes removal of the top one to three inch layer ofsand once the filter is clogged. Removal rates are around 80%for TSS and 60% for phosphorous.

To obtain maximum efficiency of the sand filter, the followingstrategies should be employed:

1. Place the filter near the area to be controlled.

2. Only runoff from impervious areas should enter the sand fil-ter to reduce the maintenance interval.

3. Generally, each chamber of the sand filter should have a surface area of 360 square feet per acre of runoff.

Technology Example 2.7 (B)

Highlighted Technology: Stormwater Management


The new EPA campus impacts nearly half of a very small, 500-acre watershed which includes wetlands, a man-madelake, and creeks. As a headwaters location, the campus has been designed with extra care � well beyond currentminimum environmental requirements. As a result, no stormwater will leave the site untreated. Most stormwaterwill pass through natural, vegetative treatment areas � which are, in turn, nourished by this storm runoff and willserve as site amenities.

Curb and gutter systems were removed during design and replaced with less costly and more ecologically-soundapproaches that slow the water flow and direct it through native grasses, flowers, forests, and wetland for treatment,not simply collection and off-site discharge. The paved area of the campus was cut in half by stacking 50% of allparking in decks and redesigning roads from four-lane to two-lane. In all, about 25 acres of mature forest werepreserved.

Wetlands � All existing wetlands were preserved, with the exception of one tenth of an acre at a road crossing. EPAadded a one acre constructed wetland on the site.

Bioretention � Innovative �pocket wetlands,� or bioretention facilities, are used at eleven locations throughout thesite. These deep, porous earth areas are planted with trees and shrubs that thrive in wet and dry conditions, andwhose roots absorb and help break down contaminants from storm runoff.

Water Quality Ponds � Two man-made ponds will help contain and slow the flow of stormwater, and aquatic plantswill aid the process of pollutant reduction and absorption.

Sheet Flow - Roads and parking lots are designed to shed water gently at the shoulders, sending stormflows through grass, wildflowers, woods, water quality ponds, and bioretention facilities before reach-ing lakes and streams.

Highlighted Technology: Water Efficient Landscaping

EPA saved on the cost of campus maintenance by minimizing turf and foregoing a lawn sprinkler system.Native or non-invasive adapted species are used throughout the campus � ensuring hardy plantings thatwill withstand the frequent droughts experienced in the Research Triangle area.

These landscaping features will save more than just water. Since the need to mow has been greatlyreduced, there will be significant resource savings and gasoline combustion pollution avoidance. Fertil-izer needs are reduced, and Integrated Pest Management practices will reduce or eliminate the need forpesticides and herbicides.

Native Trees and Shrubs � Landscape plantings of only southeastern US native trees and shrubs are plantedalong the site perimeter to enhance indigenous habitat disturbed during site clearing.

Native Grasses and Wildflowers � Wildflower meadows, comprised of indigenous warm season grassesand naturalized wildflowers, are sowed along most roadways for aesthetic value and wildlife benefit. Sixsuccessive planting stages over a three-year period insure effective establishment and viability. Twice yearly mowingto control volunteer tree growth is expected to be the only long-term maintenance required.

Plant Rescues � Prior to construction, in partnership with the NC Botanical Garden and campus neigh-bors at the National Institute of Environmental Health Sciences, EPA conducted a series of plant rescueoperations. Thousands of native plants, which otherwise would have been bulldozed during site clear-ing, were relocated out of harm�s way.

Rainwater will be collected from the roof areas of the build-ing and stored in underground tanks. The harvested rain-water will provide water for the flushing of toilets and theirrigation of one of the athletic fields. It also significantlyreduces the rainwater run-off from the site.

The rainwater collection system begins at the roof. A me-chanically-attached PVC roof membrane was chosen due toits smooth surface. Standard roof drains and leaders lead toan underslab network of pipes converging at the under-ground tanks located below an exterior plaza. The under-ground storage consists of (6) 13,000 gallon precast concretetanks linked together in series with an overflow dischargein case all cells are full. Two submersible pumps are used totransfer the rainwater to the building and to the irrigationpump house. At the building, the rainwater is filtered andchlorinated. The treated water is then pumped to the toi-lets and urinals for flushing only. The water is non-potableand will not be used for cleaning, drinking, or food prepa-ration. Through the use of an exhibit at the exterior plaza,the rainwater collection system will be an educational tooland demonstration in sustainability.

The living machine at the Exploris Museum is a natural wastewater treatment plant on site. De-signed by Living Technologies of Burlington, Vermont, the system uses natural plant and animal lifeto cleanse wastewater from the public restrooms in the museum.

Through a series of tanks, algae and plant life do the initial breaking down of the waste components.The effluent is sent through a marsh where additional plant life further cleans the water. A UV filteris the next component of the system, and the water is then pumped into an open pond where fishcomplete the process. The resulting water is clean enough from this system to be recycled as irriga-tion for plants throughout the courtyards at the museum.

If there were additional space on the site for a larger system, this process would be capable of cleaningthe wastewater to a potable condition. The Wake County Health Department has been very enthu-siastic regarding this experimental site and the demonstration it can present of alternative ways ofcleaning wastewater and recycling the end product.

Completed in 1994, the Wake County Social Services Center was in2000 the most energy efficient building operated by Wake County.It employs several engineering and architectural strategies for energyconservation. Each side of the building (except north) uses shadingstructures to maximize daylighting and minimize heat gain. All theglazing is tinted and low-e coated. The artificial lighting indoors ismostly indirect and uses only 1.1 watts per square foot. Interior light-ing is controlled with low voltagecontrols and motion sensors so that lights are only used when roomsare occupied.

The cooling system uses an ice harvester where ice is made duringthe off-peak times, mostly at night. During the primary demand timesthe stored ice is used for cooling the building.

Highlighted Technology: Optimal Energy Performance



The Clark Construction Group, Inc.

EPA�s new campus was built on a limited construction budget � benchmarked at a cost that is average forresearch and development campuses. The opportunity to invest large sums in energy systems was thereforelimited, and state-of-the art energy performance had to be achieved without extraordinary expense.

The integrated design considers all aspects of building energy use � light, heat, cooling and ventilation � andcombines systems to optimize performance. Windows, walls, and roofs are designed to work in concert withheating, ventilating, and air conditioning (HVAC) systems; laboratory fume hoods; and lights to provide anoverall 42% reduction in energy use compared to typical laboratory/office facilities.

Lights � Motion sensors and daylight dimmers ensure that lights operate only on demand. High-efficiencyelectronic ballasts and low-energy T-8 lamps cut electricity use and lower the heat load of the building.

Building Envelope � A highly-reflective, white membrane roof (albedo of 78% and emissivity of 90%) reducessolar heat gain. High performance, spectrally-selective, Low-e glass is used throughout the facility to promotedaylighting while minimizing heat loss and gain.

Mechanical Systems � High efficiency boilers and chillers provide high-temperature and chilled water to thebuilding HVAC system. Variable speed pumps and fans adjust their energy consumption to meet only theactual demands. A direct-digital-control (DDC) building automation system employs thousands of sensorsthroughout the facility to balance temperature and humidity � eliminating hot and cold spots and constantlyoptimizing energy performance.

Air Supply � Variable air volume controls manage air flow and reduce energy use. Outside air economizers useoutdoor air in lieu of conditioned air when the weather provides appropriate temperature and humidity.

Labs � For safety reasons, laboratory air is never recirculated, and the �one-pass� system for EPA�s 400 labsconsumes about one million cubic feet of conditioned air every minute. To cut down on this tremendous airflow while still ensuring worker safety, the labs have been designed with special exhaust hoods and night set-backfeatures that cut total air consumption by 50%.

Re-cycling requirements were included in all subcontract agreements.The commitment by the entire construction team -- the prime con-tractor and subcontractors, the local waste hauler, the constructionmanager, and the Government -- resulted in an overall recycling rateof 80%. A total of over 20 million pounds of waste was diverted fromlandfills.

On one section of Interstate 540, known as the Raleigh Outer Loop, the N.C. Department of Transportation (NCDOT) hasshowcased the use of recycled materials it has pioneered since 1991.TiresNineteen tons of tire chips (about 1,900 tires) were tilled into a portion of the soil along the embankments. Tire chips serveas an excellent aerator for young plants and are a much cheaper fill than pure soil. In addition, the weed mats under theguardrails were manufactured from tire chips.PlasticsRecycled plastic has been used in this project in several ways. The guardrail offset blocks�the blocks that are inserted betweenthe steel guardrails and the support posts behind them�are made from recycled plastic. Offsetting the rail from the supportposts with a plastic block stabilizes the guardrail and also helps minimize the damage inflicted to cars that may bump againstit. Plastic delineator�the flexible guideposts that help direct traffic�and temporary slope embankment pipes from plasticwere also used in the project.Post-Industrial Asphalt ShinglesNearly 700 tons of shingles��seconds� left over from the manufacturing process�have been mixed into the asphalt on asection of the Outer Loop project. These shingles make an excellent blending medium for asphalt, producing a drivingsurface that is attractive and durable.Municipal SludgeThe City of Raleigh donated 260 tons of municipal sludge to use in place of agricultural limestone fertilizer on the OuterLoop project. The sludge, which was spread along the embankments, will provide a nutrient-rich base for landscaping.Coal Fly AshA mixture of concrete and coal fly ash was used to fill the inner core of the sign posts on the project. Local power companiesdonated the coal fly ash, a by-product of the coal burning.Clearing and Grubbing DebrisThe NCDOT also established a �no burn policy.� This requires contractors to dispose of the waste generated during clearingand grubbing in a way that does not harm the environment. Instead of burning waste, contractors either mulch the materialand sell it to outside agencies or find a way to reuse it in other construction projects.

Because of the massive amount of concrete needed to build this onemillion square foot facility, the impact of trucking concrete in fromlocal batch plants would have been very costly. The negative impacton roads and air quality would have been quite significant, as well,since delivering all this concert from the nearest concrete plant wouldhave required at least 75,000 miles of truck trips.

A concrete batch plant was placed in an area already cleared for anEPA parking lot, so no additional land was disturbed. No concretetransport was made beyond the confines of the site � preventing thecombustion of at least 10,000 gallons of diesel fuel.

On-site mixer truck wastes were reclaimed at the batch plant and re-covered aggregates were reused later concrete batches. Wash waterwas contained on-site in a closed loop system. The on-site batchingwas a zero waste operation.

Contractor:


EPA developed an innovative and comprehensive strategy to insure healthy Indoor Air Quality in thecompleted facility. Multiple construction contract requirements combined to achieve this goal.

Ventilation During Construction � Filtered ventilation with 100% outside air was required during finishmaterials installation from the time the building was enclosed until facility acceptance. This was done to flush outemissions from materials and finishes and protect workers from toxin exposures.

Ambient Air Quality Testing � At construction completion, the contractor is required to test at 16 loca-tions throughout the occupied spaces of the building to measure indoor contaminant levels of CO, CO2,airborne mold and mildew, formaldehyde, volatile organic compounds, 4PC, total particulates, and other regulatedpollutants. Contaminants must be below established concentration standards prior to acceptance.

Phasing of Finish Materials � The contractor scheduled finish materials installation so as to perform�wet� finishes, which off-gas odors or toxins, prior to �fuzzy� finishes, which tend to absorb and later re-emit these chemicals.

Independent Finish Materials Testing � EPA required the contractor to conduct laboratory chamberemission testing for VOCs and particulates on four major products - wall paint, carpet, ceiling tile, andfireproofing. Test results were modeled by EPA IAQ researchers to predict indoor concentrations inthe completed facility and mitigate potential IAQ concerns prior to finish material applications.

Duct Cleaning � Prior to acceptance, comprehensive duct cleaning and filter replacement was required in order toassure that dust and other contaminants generated during construction were removed prior to building occupancy.Supply and return ducts, air handlers, and plenums were cleaned before Air Quality Testing and again immediatelyprior to acceptance of the completed building.

Highlighted Technology: Daylighting

Owner/Contact: City of Durham, Department of Solid Waste ManagementTelephone: (919) 560-4197

Architect: The Freelon Group

Contractor: Riggs Harrod Builders, Inc.

Technical Strategies: Daylighting strategies reduce energy use and cooling load due tothe reduction in the use of artifical lighting and the building�sHVAC systems.

To achieve adequate daylighting, the following strategies were em-ployed:

1. The old incinerator was oriented not by design along theeast- west axis. However, it was the perfect complement tooptimize and control the available sunlight from the south.2. The open ceilings on the 3rd floor provided an energy effi-cient glass window with a height of two floors. The openatrium glass look also provides for an efficient HVACsystem.3. To control glare and shadows that would result fromdirect sunlight entering these spaces, tinted glare film wasalso installed.4. An artificial lighting system was installed that includedhigh efficiency fluorescent fixtures and lamps coupled withphotosensors and motion sensors.

Architect:Corley Redfoot Zack, Inc.Kenneth E. Redfoot, AIATelephone: (919) 942-8586

Consultant:Innovative Design, Inc.

Contractor:J.M. Thompson Co.

Technical Strategies:Daylighting strategies have been incorporated throughout the schoolfacility, including academic classrooms, specialty classrooms, mediacenter, cafeteria, gymnasium, and student commons areas. Theinclusion of natural daylighting produces significant energy savings,reductions in maintenance, and increases in productivity by studentsand staff.

The primary daylighting system consists of �monitors� on the roof thatallow natural daylight to penetrate the building in a controlled fashion.The monitors consist of vertical windows leading to a triangular spacewith vertical light baffles that control the daylight and distribute the lightevenly around the room. Generally, the roof monitor windows facesouth to take advantage of the higher lighting levels. In certain rooms,such as cafeteria and student commons areas, the monitors face north totake advantage of different light �colors.� To augment the amount oflight reaching the monitors, a light colored roofing membrane was se-lected. A secondary daylighting system for those classrooms with south-facing windows consists of anodized aluminum light shelves that �fillin� lighting along the sides of the rooms. The daylighting monitor willbe an educational tool and physical example of sustainability
