due to childhood diseases thought to be linked to envi-ronmental causes.

“Our principal finding is that chemical factors in the environment continue to contribute greatly to childhood morbidity and to healthcare costs,” Leonardo Trasande, MD, of the Mount Sinai School of Medicine in New York City, and Yinghua Liu, MD, of the National Children’s Study New York–Northern New Jersey Center wrote.

Now, I’m a skeptic by nature. That’s why I find it a little hard to believe that environmental factors were the cause of such high healthcare costs. I’m not saying it’s untrue, I’m just saying that I haven’t seen the study in full, so I don’t know how the costs were tabulated.

But even if the dollars lost were half of that $77 billion, or a quarter of that number, or even one-tenth of that number, that’s still more than twice as much as the expected number the government would save by merging the DOE and EPA in one year. Maybe these businesses wouldn’t be so concerned with paying for the healthcare of their employees and their families if they spent less time fighting the EPA and finding ways to meet the EPA’s requirements.

While there’s still a long way to go for the bill, it remains frustrating to watch the EPA being constantly drawn under fire for it being perceived as a handicap to profitability. It’s almost like cutting off your nose to spite your face.

Cheers,

Derrick TealEditor

NOTEA National Institute of Science report estimates that 28 percent of developmental disabilities may be caused by environmental factors. While it’s difficult to say exactly what pollutants or chemicals are causing adverse health effects, manufacturers are still not required to prove that the new compounds constantly being developed for the products we use won’t make you sick.

What should make people sick is the bill introduced in May by Sen. Richard Burr (R-N.C.) that aims at merging the Department of Energy (DOE) and Environmental Pro-tection Agency (EPA) into one agency. Those backing the bill claim that the new agency will retain the authority of both departments while saving money by cutting inef-fective or redundant programs. It would save $3 billion in the first year, according to Senator Burr. But if you’ve been paying attention since the elections in 2010, you would know that it’s just another step in the onslaught against the EPA.

EPA Administrator Lisa Jackson seemed to spend more time in front of congressional hearings answering ques-tions about her agency than she did running the agency earlier this year. And those calling her in to those sessions wanted it that way. They view the EPA as a troublemaker aiming to vilify manufacturing to curb “progress” at every turn, and she is the lead antagonist — the face leading the charge against profit.

You can see this in the attacks environmental protections have come under across the U.S., including Maine, Florida, California and others … all of them stating that protecting the environment is too costly.

Yet, a recent analysis published in the May issue of Health Affairs notes that the nation lost nearly $77 billion in medical costs and missed productivity in 2008 alone

s18Best in ShowPROJECT: Green once again showcases the projects that best exemplify sustainable stone and tile design. By Derrick Teal

There are plenty of promising products when it comes to choosing green flooring. But the question remains, which is the greenest? Often, it depends on the application and installation.

When it’s time to specify a green floor, here are some environmental options: · Bamboo· Bio-based Product· Carpet (broadloom or tile)· Ceramic Tile· Certified Wood· Concrete· Cork

· Engineered Wood· Laminate· Linoleum· Reclaimed Wood· Rubber· Terrazzo (recycled glass)· Vinyl· Raised /Access Flooring · Other (which might include glass, quartz,

stabilized earth)So, how do you make the greenest deci-

sion? Consider: Does the product have a “label,” such as the Green Label Plus from the Carpet and Rug Insitute; or is it certified

(for recycled content or low emissions) by a reputable third-party certification system like GREENGUARD, Scientific Certifica-tion Systems, Green Seal, Forest Steward-ship Council or Sustainable Forestry Initia-tive? What is the product’s life cycle? How is it maintained; how is it installed (think about adhesives, sealants, underlayment, padding/cushion, etc.)?

Be sure to explore the myriad choices and environmental attributes when specifying your next sustainable floor.

CHILLAND SERVECALIFORNIA’S FIRST LEED GOLD CERTIFIED WINERY PROVES AN IDEAL APPLICATION FOR RADIANT COOLING.

CALIFORNIA’S FIRST LEED GOLD CERTIFIED WINERY PROVES AN IDEAL APPLICATION FOR RADIANT COOLING.

SUSTAINABLEFLOORING

Page 17: ED+C - June 2011

When hydronics contractor Robert Reid saw the radiant fl ooring plan for a commercial winery, he questioned whether the system would work as designed.

The plans for one of Napa Valley’s presti-gious wineries called for an in-fl oor Uponor

radiant heating and cooling system to precisely control temperatures in two vital production areas — a 20,000-square-foot winery and a 26,931-square-foot barrel cellar. Reid’s concern was that plans specifi ed the radiant tub-ing be installed at the bottom of the 20-inch-thick concrete slab, instead of sandwiched in between.

“For most commercial applications, we position the tubing in the top third or middle to ensure a comfortable heat transfer,” says the 33-year plumbing industry veteran and owner of San Rafael, Calif.-based Reid Heating & Energy Inc. “Initially, I was leery about placing the tubing on the bottom of the slab, but I discovered that this lower position made the slab more effi cient for this particular application.”

Indeed, the radiant system did perform as planned, and the project’s environmentally friendly construction recently received Leadership in En-ergy and Environmental Design (LEED) Gold certifi cation, making Hall St. Helena the fi rst winery in California to achieve this level from the U.S. Green Building Council.

The milestone has clearly pleased owners Kathryn and Craig Hall, who fi rst began planning an extraordinary showplace to produce their ultra-premium Bordeaux wines in 2003. Complete with a state-of-the-art pro-duction facility and sustainable design technologies, the couple’s long-term mission was to become the leader in earth-friendly California winegrowing.

ATTRACTIVENESS OF RADIANTRadiant heating and cooling is a fairly new trend in wineries, accord-ing to project engineer Peter Simmonds, Ph.D., with Los Angeles-based IBE Consulting Engineers, who adds that the effi cient technology helped achieve the LEED Gold status.

“We explored a range of conventional systems to newer technolo-gies, such as chilled structural beams, but radiant was the only option to deliver the consistent and precise temperature control we required,” says Simmonds, who calls the winery an ideal application for radiant. “Because temperature and humidity have the biggest impact on wine-making, it was vital to design a system that could maintain a consistent 55-degree [Fahrenheit] operating temperature. If we got this aspect of the job wrong, the entire project would have been jeopardized.”

Not surprisingly, Hall’s other winery leverages a similar in-floor radiant system to control temperatures and maximize energy/cost efficiencies.

UNIQUE PROJECT BRINGS CHALLENGESWith radiant technology approved, the design team turned its sights to-ward overcoming two of the project’s key challenges: maintaining the mandated temperature requirement and accommodating a thick con-crete slab.

“Temperature control plays a major role in the winemaking process,” says Kathryn Hall, who notes that the loss of temperature control can ruin an entire batch of wine and would result in a signifi cant loss.

As noted, the winery’s barrel cellar required a 55 F average set tempera-ture, whereas most commercial applications typically want occupants to feel a comfortable 78 F. And while the majority of the radiant system’s work is spent cooling the production areas, it is also capable of heating the space so that the ideal temperature is maintained, regardless of the outdoor temperature. A ventilation system provides supplemental cool-

ing and humidity control, as temperatures can vary among the stacks of barrels that extend from the cellar fl oor to the top of the 25-foot ceiling.

The second design challenge was to maintain the cool operating tem-perature with tubing buried in nearly two feet of concrete. Reid notes that although typical commercial slabs are between four and six inches thick, Hall St. Helena’s designers needed a thicker slab to accommodate the weight of the 10,000-gallon stainless steel fermentation tanks. The unusual fl oor thickness also provided the winery with future produc-tion fl exibility so that fermentation tanks can be relocated and secured into the slab with long bolts.

“To protect the radiant tubing from those long anchor bolts, we placed it below even the steel rebar reinforcements — so that any future slab drilling would not interfere with the radiant system,” says project engineer Simmonds. “While the 20-inch-thick slab does take longer to cool, the increased mass is ideal for maintaining the desired tempera-ture.” In other words, the thicker slab stays cooler, longer.

IMPLEMENTING THE PLANInstaller Reid used roughly 83,000 linear feet of 5/8-inch Wirsbo he-PEX tubing made of cross-linked polyethylene for the two buildings. “Luckily, there were a lot of straight runs without many bends in this project,” says Reid, who likens the large warehouse spaces to a football gridiron. “We chose the 5/8-inch hePEX because we could sustain runs up to 500 feet per loop with the larger diameter. With half-inch tube, we couldn’t really exceed 320 feet per run.”

Reid and his crew began the installation process by stapling the Wirs-bo hePEX tubing to sheets of two-inch rigid insulation at roughly six inches on center. “Obviously, with spacing so tight, we had to stagger turns and fl air out the tubing before making a turn,” he says.

With nearly 200 loops at an average of 490 feet, Reid’s football fi eld analogy wasn’t far off the mark. The Wirsbo hePEX tubing was routed to 14 manifolds that provide control for the two buildings. Once a section was stapled, a rebar mesh was laid on top of the tubing to pro-

vide support for the substantial slab fl oor.“We left the tubing under about 100 pounds

of water pressure during the rebar installation and concrete pour so we could immediately identify and replace any portion that was inad-vertently punctured,” says Reid.

All in all, he says, the project was very unique and memorable. “Although we do hundreds of commercial radiant installations a year, only one or two involve cooling — and nothing on the scale of this project,” says Reid. “Hall St. Helena was unique for its unconventional ‘cool’ temper-ature, thick foundation and the sheer size of the warehouse buildings.”

According to the project’s owners, the radi-ant system has exceeded expectations. “Green building technologies, such as radiant, have al-ways been an important part of who we are and what we do,” says Kathryn Hall. “Aside from achieving energy effi ciency, the radiant system allows our winemaking team to maintain precise control of the temperature inside our new build-ings, which is vital to ensuring the quality of our award-winning wines.”

SUSTAINABLE DESIGN FEATURES

To meet the precise requirements to become LEED Gold certifi ed, planners of the Hall St. Helena winery

incorporated many sustainable design elements and practices including:

RADIANT FLOORS – Radiant fl ooring allows Hall to control the facility’s temperature while conserving energy and

providing a stable storage and production environment.

SOLAR ENERGY – The sun provides more than 35 percent of the energy needed to power Hall St. Helena. Solar

photovoltaic cells (solar panels) on the rooftops of the barrel cellar and fermentation building convert sunlight directly

into electricity. Approximately 42,000 square feet of solar panels span the winery roofs.

LOCAL BUILDING MATERIALS – More than 10 percent of materials used to build the facility were extracted, harvested

or recovered, as well as manufactured, within 500 miles of the project site.

RECYCLED BUILDING MATERIALS – More than 10 percent of the materials used were made with recycled content.

WATER CONSERVATION – Drought-tolerant plant species selected for the winery landscaping will reduce the demand

for irrigation by more than 50 percent. All of the landscaping and vineyards are irrigated with recycled water. A

40 percent reduction of building water has also been achieved through the use of low-fl ow water outlets without

compromising performance.

September 2010. Built on 11.9 acres, it wel-comes a daily population of 549 students and 36 staff during the school year to its 18 regular classrooms, four kindergarten class-rooms and four specialty classrooms, which include areas for music, art, science and special education. The school also houses a gymnasium and library.

The Suzuki School represents the con-solidation of two schools, the Princess Anne and Concord public schools. The pre-exist-ing Princess Anne School was demolished in February 2009 to make room for the Suzuki School at 6320 Raymond Ave. The project team utilized sustainable demolition practices that were captured on the LEED scorecard, as construction debris was di-verted from the landfi ll.

The kindergarten through ninth-grade Suzuki School project was registered in 2006 with the Canadian Green Building Council under the LEED Canada-New Construction v. 1.0 rating system. It is the fi rst school in Canada to be designed, con-structed and certifi ed to the LEED Plati-

num level. The school needed just 26 points under the LEED scoring system to gain a minimum certifi cation level, but the project team opted to go for a potential 55 points in order to gain LEED Platinum.

The energy performance of the school was predicted to be 64 percent better than Canada’s minimum requirements in the Model National Energy Code for Buildings (MNECB), according to the Essex District spokesman Scott Scantlebury. The energy-effi cient school includes geothermal heating and cooling systems, solar panels, a wind mill, greywater recovery and reuse systems, GPS tracking skylights, solar light tubes, a solar thermal wall to preheat air, a highly re-fl ective roof and the polished concrete fl oor.

“We liked the minimalist approach,” says Giuliana Hinchliffe, supervisor of engineer-ing with the Greater Essex District School Board. “It was not anything extra we had to add to the building in terms of adding prod-uct.” Part of that minimalist approach can be seen in the facility’s polished concrete fl oors, which comprise nearly 15 percent

of the most highly travelled hallways on the fi rst and second fl oors.

The FGS/PermaShine system from L&M Construction Chemical used in the school is a dry-grind method of concrete fl oor fi nishing and concrete surface resto-ration that captures potential airborne par-ticulates during installation. The capturing of grinds assisted the project team in gaining LEED points in indoor air quality catego-ries, including the management of indoor environmental quality during construction.

The thermal mass of the slab is part of the polished concrete fl oor system, which can contribute to a building’s energy ef-fi ciency. That’s fi ne with the Suzuki team, which encourages its students to use hu-man energy to generate electricity with bicycles in the exercise room to power televisions in the room.

Low maintenance and environmental at-tributes of the polished concrete fl oors on the Dr. David Suzuki Public School scored high marks with the project team, according to the project’s architect.

“The owners chose polished concrete because there is no off-gassing and, for sure, the low maintenance,” says architect Greg McLean, a principal at McLean + Associ-ates Architects of Windsor.

Refl ective polished concrete fl oors complement daylighting strategies by maxi-mizing natural light and reducing electric lighting requirements, contributing to lower initial outlays for lighting and a lower long-term demand for electricity. The lighting designer incorporated building orientation, overhang, sunshades, light shelves, sky-lights, clerestory windows and light tubes

THE FUTURE OF ECO-LABELING By Nadine Gudz

I n a market cluttered with green claims, sustainability leaders are recognizing the value of increased transparency. Procurement offi cers are encouraged to ask

suppliers for comprehensive, third-party verifi ed product specifi cation information based on life-cycle assessment (LCA). It is important to look beyond the potential

environmental impacts occurring during the product’s use phase and consider the impacts from all life-cycle phases, from raw material capture through to recycling/

end of life.

The emerging standard for the coming decade: The Environmental Product Declaration (EPD). The EPD is a full-disclosure statement documenting product

ingredients, use of energy and material resources, and potential environmental impacts arising during each life-cycle phase. It meets ISO dictates and is third-party

verifi ed by organizations such as Five Winds and The Green Standard. EPDs have been enthusiastically embraced in Europe. Several contract furnishings companies

have been gradually adapting it.

EPDs represent the future of eco-labeling, making it possible to compare products based on environmental impact reduction. They serve to illuminate choices in

much the same way that ingredient and nutrition fact labels on food can support healthy choices.

Corporate transparency is critical in helping consumers make informed decisions, and EPDs can empower decision-makers with credible, comprehensive, life-cycle

based product information. While EPDs can serve as a solution to greenwashing, it is also important to question a manufacturer’s overall commitment to sustainability

and consider its corporate mission and culture, use of renewable energy, water reduction and zero waste strategy.

to fi nely incorporate natural light. The designer muted potential glare on the south facing side of the building while welcoming the less direct sun-light surrounding the rest of school.

Much of the natural light reaching the polished concrete fl oor sys-tem throughout the corridors came through the north and south facing clerestory windows, bouncing off light-colored walls to the fi rst fl oor and providing a secondary source of light for the classrooms along the way.

SUSTAINABLEFLOORING

That’s just another one of the bright ideas about the school’s design the students see every day.

While the building’s technologies assist in teaching environ-mental science lessons, low-VOC finishes maintain indoor air quality, which balanced with just the right amount of natural light, have created an environment for learning that enhances academic achievement.

“Green practices and ecological literacy permeate every aspect of the culture and academic life at Dr. David Suzuki Public School,” says school principal Judy Wherry. “Our goal is to prepare the students to be environmental architects of the future and to be caretakers of their school, community and world.”

The facility is under the careful watch of the Greater Essex County District School Board and participates in Ontario’s EcoSchools pro-gram, which “aims to infl uence young people during the formative pe-riod of life, and effect an exponential impact as children take a culture of conservation home.”

From their minds to the bottoms of their shoes, students are learning to leave smaller footprints. The simple but smart concrete fl oor helps them understand the concept of doing more with less.

In this patio project, stone scrap saved over the years was organized by material and color into crates, and the approximate square footage was cal-culated. The scrap stones were shattered and unusual jet-cut scraps were turned into fl ora and fauna-themed medallions. The resulting shards and medallions were used to fabricate the surface of the patio and of 24"x24" concrete patio blocks. With large sweeping waves of white, blue and grey stones, and a vast cream fi eld, the southern New Hampshire patio more than achieves an otherworldly feel. Although the design is unusual, the large size of the patio and choice of classic colors add a sense of sophistication. The application of shattered stone has meant that there has been no prob-lem with guests slipping. The testing for heat absorption before creating the stone blends has prevented scorched feet, even during the hottest and sunniest days of the season. To the added delight of the client, the inclusion of fl ora and fauna medallions has been a hit with parents and children; children enjoy the challenge of counting and identifying the scattered medallions.

The ReVISION House in Orlando, Fla., is a full gut renovation of a typical one-story ranch home built around 1957 designed to meet a number of sustainability standards. In the main areas of the home, which included the foyer, living area, kitchen, dining room, fi replace/wine room, laundry room, pow-der room and three bathrooms, the designer specifi ed the use of ceramic or porcelain tiles for fl oor- covering. The reason for this was for more than good looks. Not only was it attractive, but ceramic tiles have a design aesthetic that can’t be duplicated with any other materials. Quality materials such as ceramic tile can last for many years. Because the quality of the indoor air is essential in a tightly insulated building envelope, the use of very low-VOC adhesives and grouts were used throughout. The main area of the home features a 24"x24" ceramic tile that features a unique texture and emulates the look of fabric. It contains up to 40 percent recycled content. In the kitchen, the backsplash tile from is made of recycled glass, which is made from at least 85 percent recycled content. In the dining area, a faux wood-look plank tile contains 42 percent post-consumer recycled content.

This remodel of an existing clothing store was simply to refresh the once dark space (with black painted ceiling and black 12"x12" ceramic fl oor tile), and transform it into an enchanting white space. The new fl ooring is a 24"x24" “White Ice” crystallized glass on porcelain. It was cho-sen not only for its striking glossy look, but for its similarity to Thassos marble and for its durability.

In the 16th century, Juan Ponce de León was said to have searched far and wide for a mythi-cal fountain whose waters restored youth. Budget constraints might require many facility managers to do the same, but instead of using the water to restore their own youth, they’d like

it to restore their carpeting.According to a joint study by ED+C and Sustain-

able Facility, facility managers are considering carpet-ing ahead of other fl ooring types. The facility man-agers surveyed cited durability, ease of maintenance, function for space, warranty and price as the top fi ve attributes they looked for when specifying sustainable fl ooring.

Now, some of you might be mentally comparing carpeting with other fl ooring types, most notably hard-surface fl ooring, and thinking hard-surface fl ooring is either comparable or superior in many of those categories. However, a study by McGraw-Hill Construction had similar results, citing noise control, aesthetics and slip resistance as reasons for the facility managers it surveyed choosing carpeting.

For whatever the reasons facility managers choose carpet, the fact is that keeping carpet looking clean and new are essential components to extending car-pet life. What sustainable steps can they take (no pun intended) to make it happen?

OUT OF SIGHTSince this article is about prolonging all carpets (or at least most carpets), we won’t talk about brand selec-tion, the longevity of different fi bers, or whether car-pet tiles or broadloom is better.

According to the Carpet Cushion Council (CCC), an association designed to educate organizations and manufacturers regarding carpet cushions, ensuring long-lasting carpets starts even before the carpet gets put down. The organization states that carpeting is of-ten replaced not because it’s worn out, but because it

has “uglied” and lost its attractiveness.When carpet cushion or padding is properly

combined in a system with carpet, the ability of the fl oor covering to absorb walking impact rises dramatically. Better impact absorption results in the carpet losing less pile height. A reduction in pile height causes the carpeting to look more worn.

A study cited on the CCC’s site stated that without cushion, carpets showed a 19.3 percent loss in thickness while carpets with cushion suf-fered only a 5-10 percent pile height loss. There-fore, fi bers of a carpet installed without cushion can become compacted more easily, and the “new” look of the carpet may disappear more quickly.

GRIME FIGHTER TRIOWhile padding will help deal with wear, it can’t exactly help with other factors that can cause carpeting to lose its appeal. So once the carpet has been installed, “Hands down, the best way to extend the life of carpet is having a good maintenance program in place,” says Stephen Lewis, technical director for MilliCare, a leading provider of sustainable carpet and textile main-tenance for commercial buildings. “Without a regular program, carpet will not only look dirty faster, but the abrasive soil that is left in the carpet will wear down the fi bers. The carpet will then look dull, because of the way the damaged fi ber refl ects light.”

The fi rst step to a maintenance program literally begins with the fi rst steps of the build-ing’s occupants and visitors. “Estimates range

as high as 90 percent of the soils brought into a facility are walked in on shoe bottoms,” says Christopher Tricozzi, vice president of sales and marketing for Crown Mats and Matting. “To prevent this, we need what I call a butler at the door — not collecting shoes as people walk in — but instead making sure an effective high-per-formance matting system is installed to stop soils and debris from entering. This includes: fi ve feet of scraper mats to remove large debris and mois-ture; fi ve feet of scraper/wiper mats to remove remaining debris and moisture; and wiper mats, which are placed directly inside a facility for any existing moisture.”

Lewis agrees that barrier mats are an excel-lent way to prevent the dirt and debris from ever reaching the carpet, and adds “Other steps are to clean or sweep the sidewalks leading up to the entrances of the building and cleaning or sweep-ing dirt and debris from the parking lot.”

KEEP IT CLEAN“Spots and stains are one of the biggest detri-ments to high appearance levels,” says Lewis. “In order to maintain a consistent appearance level between periodic maintenance, it is critical that spots and stains be removed immediately or as soon as possible.”

Seems like common sense, right? We all know that the best way to remove spots and stains is to get to them immediately. One of the best ways to do that is to install what is essentially a preventa-tive maintenance program. Doug Berjer explains.

“Preventive maintenance is the name of the game when it comes to carpeting,” says the product manager for CFR (Continuous Flow Recycling) portable carpet extractors. “It all starts with the matting systems dis-cussed earlier, but also includes vacuuming and spotting schedules. We should also now bring in carpet cleaning. When it comes to carpet cleaning, facility managers should not depend on how a carpet looks before de-termining if it should be cleaned. Carpet is made to absorb dust, dirt and contaminants. Therefore, a carpet may be more soiled than it appears. Additionally, if a carpet becomes overly soiled, it can become more diffi cult to remove spots and stains.

“A wise move is to establish an ongoing carpet cleaning program using carpet extraction, which

is the most effective at removing soils from car-pets,” he adds. “Cleaning carpets on a set sched-

ule also helps to maintain carpets’ appearances and functionality for longer.”

GET WITH THE PROGRAMOpting into a maintenance program customized for a facility type is often the easiest and best way to ensure the carpet is properly cared for after its installation. The best time for implementing the program can range from two weeks before instal-lation occurs, to provide ample time in identi-fying problem areas, to just after the carpet has been installed.

“When selecting a program, the amount and type of soil being tracked in needs to be taken into account,” says Lewis. “What are the level of traffi c and the nature of the business? Additionally, the type of weather and climate should be taken into consideration. This will lead you to different types of cleaning methods and programs. For example, if you have carpet coming in from a dirty ware-house, you would need more aggressive cleaning methods than a high-rise offi ce building.

“Be sure to look for a maintenance plan that uses green chemicals certifi ed by third-party or-ganizations, such as Green Seal, Environmental Choice or DfE,” Lewis adds. “Additionally, look for providers and technicians that have been cer-tifi ed to CRI’s Seal of Approval program.”

The equipment being used in the cleaning process can have a huge environmental impact according to Berjer. “To effi ciently clean carpets, carpet extractors are required. These machines have the pressure and power to reach deep into carpet fi bers and dissolve and remove soils. One drawback with some carpet extractors, which managers concerned about green and sustain-able issues must be aware of, is that most extrac-tors use large amounts of water, as much as one gallon per minute, and chemicals.

“However, there are carpet extractors now available that fi lter and recycle water and clean-ing solution as much as seven times before these resources must be emptied and replenished. This dramatically cuts back on water use and chemical needs. And as a side benefi t, worker productivity is also improved because the clean-ing professional does not have to stop, empty and then refi ll the machine as frequently.”

But much like Ponce de León’s futile search through Florida, there is no true fountain of youth for carpet. No matter the padding used, maintenance program and love carpeting re-ceives, the fi bers will eventually wear and need replacing. All facility managers can do is care for it to make it last as long as they can.

PROPER PRODUCT SELECTION

By Roger McFaddenMaintaining carpeting in commercial buildings and facilities has evolved

beyond product performance to ensuring that products are also safe for

the environment and people. There are several new high-performance

products that can help achieve cleaning, sustainability and budget goals,

so consider the following when evaluating carpet cleaning products:

PRODUCT EFFECTIVENESS

Select carpet cleaners, spot removers, degreasers and pre-sprays that

are high-performance and will effectively remove both water and oil-based

stains. Confi rm that these products will not leave residues that can later attract oils and soils. Selecting

products in the neutral pH range will prevent potential damage to carpet fi bers, colors and textures.

SAFETY CONCERNS

Frequent exposure to harsh chemicals, through application or accumulation in the carpet fi bers, can be harmful

to people and the environment. Avoid toxic chemicals that are persistent, bioaccumulate or are toxic to human

or environmental health. Innovative product manufacturers today are using green chemistry principles to

develop safer and more sustainable carpet cleaning solutions. An easy way to determine if a cleaner is safer for

the environment is to look for credible, independent third-party certifi cations from science-based organizations

like Green Seal and the EPA Design for the Environment.

BUDGET FRIENDLY

Sustainable carpet cleaning products may actually be your lowest total-cost alternative. Smart and innovative

product design has created sustainable cleaning solutions that are multi-use and highly concentrated resulting

in a much lower in-use cost when diluted with water. Additionally, green chemistry design has led to carpet

cleaners that are formulated with plant-based renewable materials that are cost competitive with conventional

oil-based derivatives used in traditional cleaning products.

One of the many benefi ts of my career is that I occasionally get to make pre-sentations to

cleaning professionals, building manag-ers, green advocates and others regarding green cleaning: How to make cleaning healthier for people and more effective while reducing its impact on the environ-ment. One of the things I value most is that while those attending these talks typi-cally come to learn things that will help them green their facilities, I too can learn quite a bit — especially about their clean-ing needs and challenges.

Typically, this occurs during the ques-tion-and-answer period after my presenta-tion. And the topics that now tend to get the most queries and generate the most concern are often about green fl oors and green fl oorcare.

Here are some of the key points from a recent presentation regarding green fl oors and fl oorcare, along with some of the questions and answers that followed.

WHAT ARE GREEN FLOORS?When I talk about green fl oors, I am typically referring to hard-surface fl oors.

Some of the key components of a green fl oor include the following:

The fl oor is made from renewable or recy-cled content.The fl oor is itself recyclable.No environmentally harmful ingredients are used to manufacture the fl oor; additionally, the manufacturing process itself is environ-mentally responsible.The fl oor is durable and long lasting; in most cases, it should last as long as a con-ventional hard-surface fl oor covering.

The fl oor is installed in an environmentally responsible manner; specifi cally, installation uses products that have few, if any, volatile organic compounds (VOCs) that can nega-tively impact indoor air quality. Additionally, because the categories of green

and sustainable are now merging, the green fl oor should be manufactured in an “enlight-ened” company that is socially responsible and embraces environmentally sound practices in its own operations. Further, packaging and distribution of the product should address sus-tainability issues. For instance, some end users now prefer to work with local vendors to re-duce the amount of fuel necessary to transport fl ooring materials.

WHAT ARE SOME EXAMPLES OF GREEN FLOORS?There are many types of green fl oors, and it often depends on how innovative the facility wishes to be as far as which one to choose. For instance, one very high-tech building in Chicago installed rest-room fl oors made from reprocessed broken glass and fl oor tiles. It then used recycled egg cartons for partitions and to form the molding along the base of the walls. However, typically when I dis-cuss green fl oors I am referring to the following:

Bamboo, which is actually made from a grass and considered to be exceptionally durable; moreover, it often looks very similar to tradi-tional hardwood fl ooring.

Cork, which has a softer feel and is fire, rot and termite resistant.Conventional hardwoods that have been grown in managed forests, where new trees are planted when older trees are cut down.Rubber, often obtained from recycled tires.Concrete, a somewhat controversial green flooring since it often requires considerable fuel and energy to make and transport.

CAN YOU USE CONVENTIONAL FLOORCARE PRODUCTS ON GREEN FLOORS?The answer is yes, but should be a very big no. Yes, in most cases you can use conven-tional floorcare strippers, restorers and fin-ishes when or where necessary. However, this can defeat the whole purpose of install-ing a green floor.

Several years ago, Dr. Greg Norris of the Harvard School of Public Health reported that “the amount of VOCs emitted using [conventional floorcare chemicals] from a single application is comparable to the total amount of VOCs a green floor will emit over its entire lifetime.”

This is why green floorcare — in fact, all green cleaning — is only as effective as its weakest link. Green cleaning requires that all products and materials used in the cleaning process, including the maintenance of floors — strippers, sealers, finishes and restorers — be proven green by being green certified.

Some fl ooring products, like Monocibec’s Modern ceramic tile (above) and TOLI’s FasolPlus homogenous vinyl tile (below), contain high levels of recycled content.

Page 33: ED+C - June 2011

S23Cwww.EDCmag.com

WHY? WHAT IS IN CONVENTIONAL FLOORCARE PRODUCTS THAT MAKE THEM SO DETRIMENTAL TO THE ENVIRONMENT?Before answering this, I want to say that con-ventional fl oorcare products have served us well. Several are high performing and have helped maintain fl oors exceptionally well over the years, and the fi nishes can provide the high-gloss shine that many end customers insist on.

However, many do contain high levels of VOCs, as Dr. Norris referenced earlier; 2-bu-toxyethanol, now considered a carcinogen; zinc and other metals to produce that high-gloss shine; petroleum by-products and other nonrenewable ingredients; along with other ingredients that can be potentially harmful to human health.

This defi nition from Stephen Ashkin, one of the cleaning industry’s leading green cleaning advo-cates, will possibly clarify what green fl oorcare is all about: Green fl oorcare involves cleaning, polishing and maintaining fl oors with chemicals, products, tools and equipment designed to have a reduced impact on health and the environment when com-pared to conventional products used for the same purpose. Tools, chemicals and other fl oorcare equipment that do not meet these criteria should not be used on a green fl oor.

ARE THERE GREEN EQUIVALENTS TO THESE CONVENTIONAL INGREDIENTS?I would have said yes had I been asked this question fi ve years ago. However, I would’ve been forced to admit many green products can be more costly and the performance levels, compared to conventional fl oorcare chemi-cals, can vary. However, this is not necessarily the case today. Some green cleaning chemi-cal manufacturers have invested considerable time, energy and funds into not only improving the performance level of these products but, in the process, have lowered the costs to produce the products and passed the savings on to the end customer.

HOW CAN I SELECT GREEN FLOORCARE PRODUCTS?I am asked this frequently, and there are actu-ally two simple answers.

First, look for products that are green certified by an established, respected certi-fication organization. This means the prod-uct has been independently tested to meet specific standards that prove it is green.

Once certified, the certification mark will be proudly posted on the product’s label.

Second, find a green-astute janitorial product distributor. Would you purchase a high-definition television from a sales-person who specializes in selling washing machines? How about a car from a travel agent? Clearly not. In the same vein, a green-knowledgeable distributor will know what green cleaning is all about, including what products work best in which situa-tions, meet your specific needs and perform best on different types of surfaces. Very often these distributors work with manu-facturers that make only green cleaning products as opposed to manufacturers that market green products as a sideline.

WHAT ABOUT TOOLS AND EQUIPMENT? WHAT ROLES DO THEY PLAY IN GREEN FLOORCARE?Excellent question. Remember earlier I said that green cleaning requires all products to be green. This applies to the tools and equipment as well.

One way to select green fl oorcare tools and equipment is to see if they meet the require-ments of LEED-EBOM 3.7. In general, this refers to equipment that uses less water, chemi-cals and energy compared to older or conven-tional machines.

The floor machine specifically should have a vacuum system and other features to cap-ture and hold impurities generated in floor cleaning so they do not become airborne.

Additionally, it should be quiet — the noise level must not exceed 70 decibels — and er-gonomically designed with reduced torque and vibration. Remember, green cleaning is as much about protecting the health of the cleaning worker, the building occupants and visitors as well as the environment.

WHAT’S ON THE HORIZON FOR GREEN FLOORS AND FLOORCARE?I honestly believe we are seeing a new indus-try blossom. Nearly all of the floorcovering manufacturers are getting much more envi-ronmentally conscious. They realize the old ways of manufacturing products are not only unsustainable, but also they no longer make economic sense. Alternatives that are greener and more sustainable are becoming the only options available for these manufacturers.

Further, I believe the cleaning industry, and spe-cifi cally fl oorcare, is going to grow much further and faster than anyone anticipated a few years back. Now end-use customers are going to look for and select proven green cleaning products for all pur-poses and only accept non-green products when none are available or their performance or costs are unacceptable. Fortunately, there are fewer and fewer situations where this is necessary.

Some cleaning systems, like the nora pro clean system specifi cally for nora products, eliminate the use of detergents and chemicals.

DyDynamicnamic Form

E leven Times Square is a sculptural, glass-clad office tower occupying a full block on one of the world’s most celebrated urban thoroughfares: Manhattan’s 42nd Street. Designed to extend the vibrancy of Times

Square, its dynamic form is an essay in contextual and solar response. LEED Gold certified and designed to earn ENERGY STAR, Eleven Times Square has also achieved the status of ED+C’s 2011 Excellence in Design Commercial category winner.

SJP Properties, a N.J.-based developer of specu-lative and build-to-suit office space, requested an extraordinary, environmentally responsible modern building befitting its marquee location on the corner of 42nd Street and Eighth Avenue. As the last project of the Empire State Development Corp.’s 42nd Street Development Project, the agency wanted a dynamic building that — along with the neighboring Westin Hotel and New York Times Building — would create a western gateway to Times Square.

The high-rise is based on first-principles of environ-mental design. Eleven Times Square is the first major tower in New York to have varying curtain wall treat-ments on its north and south façades, which were chosen to minimize energy use and create an optimal working environment. The high-performance, ener-gy-efficient and environmentally responsible tower utilizes sustainable and renewable resources, mini-

mizes environmental waste and pollution, optimizes indoor air quality and seeks to reduce or eliminate contact with toxic or hazardous conditions.

Goals and Solutions The following were the goals set for the project:

Capitalize on and extend the vibrant 42nd Street entertainment district, while at the same time cre-ating an appropriate setting for corporate tenants;

Invent an architecture where super-scale media and architecture can coexist and reinforce each other;Create state-of-the-art office space that promotes healthy, flexible and gracious workplace environ-ments for various workplace tenants; andAchieve the highest level of sustainability within the paradigm of urban speculative office building.

The process of creating solutions involved the rec-onciliation of the “top-down” master plan goals of the state and the “bottom-up” goals of the developer and occupants. Common ground between these two was found in a number of strategies. The outward sloping form achieves a civic gesture of a gateway while simultaneously creating more floor area in the upper, valuable portion of the tower. The transparent lobby serves as a continuation of the Time’s famously open ground floor while providing a refreshing take on this

tired aspect of office building design. The variations of the building’s façades promote Times Square dynamism while also responding to solar orientation and allowing for substantial glazing.

In order to create the right feel for the location, three nestled components comprise Eleven Times Square’s structure: a six-story ribbon-base; an outwardly sloped glass-clad “crystal”; and a south-facing 40-story spine. The six-story base that wraps 42nd Street and Eighth Avenue maintains the predominant theater scale of 42nd street and its vibrant retail continuity. At the corner of 41st Street, a dramatic lit beacon signals a “hard stop” to this environment, and the expression is calmer, more transparent and refined. The strong horizontal striation of the six-story base provides a foil for the random and ever-chang-ing arrangement of the signage. The sloped crystal is an inversion of the typical Manhat-tan model where buildings taper as they rise. Here, the building’s form cants outward by 30 feet, opening up views for pedestrians on the sidewalk and providing commanding views for the offices up above, giving the effect one is floating over Eighth Avenue.

A number of strategies for a healthy building were employed in the design, and the building recently received LEED certification level due to its design and operation. Building systems were designed to reduce energy consumption, while a sophisticated building management system (BMS) controls and monitors mechanical systems. The air handlers installed are equipped with MERV 15 filtration (90-95 percent efficient), which is approximately 65-70 percent more efficient than MERV 6 (20-30 percent) filters required by ASHRAE 62.1-2007. To ensure that the equipment operates as designed, a rigorous program of commissioning for all mechanical equipment was put in place. A stormwater detention and filtration system reduces site runoff and reuses the water for the cooling towers. The high-performance curtain wall — with low-E spectrally selective glazing and increased thermal insulation — has an overall U-factor of approximately 15 percent lower than recently completed or under construction NYC Class A office buildings. Continuous floor-to-ceiling glazing provides abundant daylight and exterior views to occupants, and the exterior sunshades and silkscreened

fritted glass reduce interior glare and improve thermal comfort. Ninety-five percent and 84 per-cent of the occupied areas of the building have views and receive daylight respectively. High albedo roof pavers were specified to reduce heat gain, and high-quality interior work spaces were constructed with low-VOC emitting materials. The wood products used maintain Forest Stewardship Council certification. Storage for recyclables was included, and green housekeeping procedures and cleaners will be used to maintain the build-ing.

Office buildings in this climate are almost always in cooling mode, and therefore the reduc-tion of solar gain was a driver of the building’s form and expression. Its various “skins” relate to solar orientation; the south portion of the build-ing — exposed to the most sun — has reflective glass and perforated aluminum sunshades that cut down on glare and heat. In contrast, the 42nd Street portion is sheer and more transparent, welcoming in softer, northern light. The south façades also incorporate projecting sunscreens for energy and glare control. The building saves 29.4 percent in total site energy usage compared to the Performance Rating Method (Appendix G) of ASHRAE 90.1-2004, excluding tenant equip-ment and lighting.

Integrated, Not ImposedThe team and owners made sure the architecture of Eleven Times Square works with the community, not against it. A new subway entrance is incorporated into the base of the building. The careful mass-ing of the building reinforces the public realm. At

street level, unique environments were created in the three different micro-contexts: energetic commercialism at 42nd Street and Eighth Avenue; a calmer, transparent demeanor on 41st Street;

and a corner lobby animated by a mobile by artist Tim Prentice. At the city-scale level, the canted crystalline form preserves view corridors to various historic landmarks, creates a western gateway to Times Square and cuts a unique profile on the New York skyline.

The comprehensive incorporation of sustain-ability will benefit the large number of building users as well as the greater environment by a

reduction in energy consumption and carbon footprint. The innovations on the exterior wall, especially as it relates to building of this scale, work to advance the discourse of outstanding sustainable tall building design.
