Building owners, facility managers and architects are allconcerned with the impact building creation andoccupation/use have on our energy and resources. A

critical reevaluation of traditional practices and productsused for each space within a building is necessary tosatisfy sustainability requirements.

Green buildings not only provide environmental benefits

by reducing the impacts of natural resourceconsumption, but also provide economic and health andsafety benefits.

High-efficiency products are the key element in next generation green restroomDesign. From toilets and urinals to faucets and high-speed hand dryers, todays greenrestrooms blend design and innovation to reduce water, energy, maintenance and

waste.

The High-Efficiency FactorHigh-Efficiency Factor



12/85



Restrooms are a cost center. Water, electricity, paper, maintenance and waste removalexpenses add up quickly, impacting a facility managers bottom line. Upgradingrestrooms with high-efficiency products immediately saves time, money and the

environment.




13/85



High-efficiency products conserve water, reduce electrical consumption and

eliminate waste:

High-efficiency toilets, urinals, and faucets: Low-flow fixtures save water, and thatresults in pumping less water, which in turn saves energy. Less water also meansreduced drainage, which equates to less energy for treatment and discharge.

High-speed, energy-efficient hand dryers: Next generation high-speed hand dryersuse 80% less energy than conventional hand dryers. They also deliver a 95% costsavings compared to paper towels and eliminate their maintenance and waste, whilecreating a more hygienic restroom environment.

High-efficiency products help facilities qualify for a range of LEED credits.

In 2012, two-thirds of the U.S. experienced adrought and the US cost of water has risen, onaverage, 27% in the past five years.

It is predicted that by 2015 drinking wateraccess could be a major source of world conflict.(U.S. Central Intelligence Agency).

Water is needed to produce energy. Energy is needed to deliver water; energy plants aredependent on water. Water is used for cooling at power plants and operations areaffected if water levels in rivers, lakes or aquifers get too low. Water shortages lead to

blackouts.

The biggest use of electricity for most cities is supplying and treating water. 13% of ourelectrical energy goes to heat, treat and pump water supplies.

Water and EnergyWater Consumption

U.S. public water supply/treatmentfacilities consume about 50 billionkilowatt-hrs per day. Thats enoughenergy to power over 4.5 millionhomes for an entire year.

Bio Fuels: Making 1 gallon of ethanolconsumes 100 gallons of water onaverage.

Researchers say the cost of waterwill increase more than the rate ofinflation. The price is determined by

a few main factors: the cost oftransporting from source, totaldemand, price subsidies, andtreatment. The water rates arecheaper now than they ever will be

in the future.

Average rates in the top 30 U.S.cities went up over 9% in 2011alone. In some places, rates have

gone up over 25%. Some peopleare starting to call water BlueGold.

Another method that we can use to help reduce water usage is water rebate programs.These are available in several states. A water rebate program is really quite simple: Youreplace a high water-consuming product with a lower water-consuming product, and the

state will reimburse a certain amount of money to help offset the cost of the new productthat was purchased and installed.

In some cases, the new product may be paid for outright; some pay 50 percent. Eitherway, you are given some amount of money as an incentive to replace the old water-

consuming product with a higher efficiency product.

Reducing Water Use: Rebates

Arizona The state is offering a rebate on replacement HE water heaters. City of Tucson is offering a rebate on

HETs that are installed to replace pre-1991 toilets in nearly all applications.

California Bay Area water providers are offering rebates for HETs in households, and HETs and HEUs in

commercial restrooms.

ColoradoCity of Boulder is offering a rebate to both residential and commercial customers who install HETs.

New York New York City is offering a rebate of $125 to replace old, water-guzzling toilets.

Texas San Antonio Water Systems provide free HET, HE showerheads and aerators - $150 rebate for on

Washington Seattle area water providers are offering rebates for WaterSense- labeled toilet replacements.

Water Consumption

21/85



In terms of water use, we need to understand that in 1950 with a population of about a150 million people, water usage was at 14 billion gallons per day in the United States.

In the year 2000, with population at 282 million, water usage was 43 billion gallons perday. That is a population growth of 88 percent, yet it is a water use increase of 207percent. This means that not only do we have more people using the finite amount ofwater, but the way were using it has also increased significantly.

As the population expands and communities grow, water is being used to fill swimmingpools, for sprinklers, and even to hose down patios or places where people eat outside.

Water UseWater Consumption



22/85



In order to truly understand the water use, we need to look at it industry by industry. Notethat office buildings, schools, hospitals, hotels and motels do not use water the same way.Not surprisingly, hotels and motels use a lot in their guestrooms and in their laundry

facilities.

Water Usage per IndustryWater Consumption



23/85



Similarly, hospitals use large amounts in their domestic bathrooms and restrooms,whereas in office buildings, youll see that heating and cooling, much like in schools,represents a higher percentage of the water use. There is still a high percentage of waterused in restrooms or domestic bathrooms in each and every one of these applications.

Water Usage per IndustryWater Consumption



24/85



The chart below shows a breakdown of typical indoor commercial water use. Toilets andfaucets consume the most amount of water, followed by laundry and washing/sanitation.

Typical Indoor Commercial Water UseWater Consumption



25/85



A similar trend occurs in domestic water use, with toilets and showering using themajority of the water. The plumbing fixtures specified for those areas will have adefinite impact on overall water use.

According to the EPA, a leaking toilet can waste 200 gallons a water a day. A drippingfaucet or showerhead can waste up 1000 gallons per week. If these leaks were fixed, itwould save approximately 177 billion gallons of water a day.

What is a high-efficiency toilet?

A HET is a fixture that has an average flushvolume of 1.28 gpf or less, meets theperformance requirements of ASME19.2/CSA B45.1, and passes the 350grams in maximum performance testing(MaP).

Dual-flush devices (1.6/1.1 gpf) areconsidered HETs.

A HET uses 20% less water than most

toilets on the market today, which aregenerally rated at 1.6 gpf.

High-Efficiency Toilets (HET)Water-Saving Products



29/85



Single-flush 1.28 gpf models are available as manual, battery-powered and hardwiredproducts. Electronic products have become popular because they are more hygienic andcleanse the fixture after the user leaves; however, manual devices are still very popular.

Manual dual-flush products require high-efficiency toilet bowls, the later generation1.6 bowls or 1.28 single-flush HET bowls.

The manual dual-flush handle is availableto retrofit onto existing valves, and they arealso available as a complete valve for usewith 1.28 or 1.6 bowls.

Solar-powered flushometers are available in a single-flush electronic product or, onceagain, in a dual-flush electronic product. The key advantage with the solar products isthat they use less battery power and have their power source augmented by the light inthe room. The battery life is extended two to three times the normal battery life of aregular battery-powered product.

An HEU is a urinal with a maximum flushvolume of 0.5 gpf or less, and must meet theperformance requirements of ASME 19.2/CSAB45.1.

A 0.5 gpf HEU uses 50% less water than thestandard urinal (at 1.0 gpf).

HEU gpf options are 0.5 gpf, 0.25 gpf, 0.125gpf and waterfree.

An HELF is a lavatory faucet with a maximum flow rate of 1.5 gpm and a minimum flowrate of 0.8 gpm, and must meet the performance requirements of ASME 112.18.1/CSAB45.0.

The current lavatory faucet standard is 2.2 gpm.

While not specifically qualified as a high-efficiency lavatory faucet, electronic faucetsare certainly another method that willconserve water, primarily in a commercialenvironment. These are faucets that turn onwhen theyre used and off when they are not.Electronic faucets are essential to achievingLEED points, because they are only on whenused and off during periods of nonuse, andtherefore help to conserve water and eliminatewaste. They generally offer:

High-efficiency showerhead product specification is the newestproduct standard from the EPAs WaterSense program. Themaximum flow rate is 2.0 gpm. In addition, there are veryspecific performance requirements associated with how theshowerhead functions, such as the ability to rinse, the patternthat the showerhead gives off, and the overall efficiency of theshowerhead itself. These requirements ensure the limited flowdoes not hamper the shower experience.

With a low-flow showerhead, hot water use for an averageshower can be reduced from 50 gallons to 20 gallons or less.

There are a wide variety of low-flow showerheads available,

including the popular pulsating or massage type. Some ofthese showerheads incorporate a valve or push-button thatinterrupts the water flow while soaping up, saving even more.

Hand Dryers




40/85


Historically, hand dryers have not been popularbecause they take too long to dry handscompletely. It takes about 10 seconds to dryhands with paper towels, and with a traditionaldryer (the old industry standard), it can takeabout 35-45 seconds.

This is why hand dryers are installed in only

10% of restroomsuntil now. The new industrystandard high-speed, energy-efficient dryerchanged the perception of hand drying.

How High-Speed, Energy-Efficient Hand Dryers WorkHigh-Speed

Energy-EfficientHand Dryers

Research discovered that wet hands are covered with water in two forms:

Loose droplets

Residual moisture layer

The traditional hand dryer only removes the droplets of water, not the residualmoisture. Blowing droplets off with a focused high-velocity airstream eliminatesexcess water in 3 4 seconds. Not all high-speed dryers have a focused enough airflow

and thus take longer to blow off excess water; 18,000 linear feet per minute (LFM) orabove is optimal. A stream of air at 135F (57C) rapidly evaporates the remainingboundary layer of water. Not all high-speed dryers heat the air, and therefore,they leave the residual moisture layer on hands. Damp hands are better able to carrygerms and cause cross-contamination. The traditional dryer takes 30 45 secondsversus the high-speed dryer with hot air which dries completely in 10 15 seconds. Ascientific white paper set a value for dry hands at .2 grams of moisture left onhands.

The Environmental Building News commissioned LCA experts to perform a comparisonof:

virgin paper towelsrecycled paper towel

standard hand dryers, and

high-speed hand dryers.

The study considered energy used to harvest raw materials and manufacture papertowels and assumed two towels per use. For the dryers, the study assumed the U.S.average of 11,470 Btu/kWh to calculate the energy to produce and transmit electricity.The study did not include energy for the disposal of the paper towels nor the

administrative and maintenance costs for paper towel use.

Results overwhelmingly support the high-speed dryer for total cost and efficiency.

1. Estimate from database developed by Franklin Associates, Ltd. of Prairie Village, Kansas and used in the SimaPro LCA software. Includesenergy used to harvest raw materials and manufacture paper towels.

2. Based on pre-folded towels from a national distributor.

3. Based on data from Excel Dryer and informal EBN testing.

4. Assumes two towels per use. For dryers, includes energy used to produce and transmit electricity, based on U.S. average of 11,470Btu/kWh. Energy for disposal of paper towels is not included. Energy for additional cooling to compensate for dryer use is not includedadding that load would increase dryer energy burden by about 1/3 when space is mechanically cooled.

5. Assumes two towels per use, and national average electricity cost of 8/kWh. Administrative and maintenance costs for paper towel use(ordering, receiving, storing, refilling dispensers, disposal) and additional cooling load from dryer use are not included.

In March of 2009, a complete beginning-to-end life cycle assessment (LCA) wasperformed to compare the environmental performance of paper towels, 100% recycledpaper towels, standard hand dryers and high-speed, energy-efficient hand dryers. Thestudy was peer reviewed by an independent panel of LCA experts per ISO 14040standards, which is internationally recognized as the gold standard for performing LCAstudies. This assessment took into account the total climate change impacts or globalwarming potential over the entire life cycle of each system. It measured the carbonfootprint of each system in KgCO2 eq.

Several scenarios were usedfor example, source of electricity to power the dryers,length of drying time, % of recycled paper in the paper towels and alternate towel usagefor the towel systems.

Historically, there was concern that hand dryers harbor germs. In 1994, a University ofWestminster study funded by the tissue paper industry found that warm air dryers couldincrease the amount of bacteria on hands and encourage the growth of bacteria. In2000, the Mayo Clinic refuted these results in a study entitled, Effects of 4 Hand DryingMethods for Removing Bacteria from Washed Hands: A Randomized Trial.

The Mayo Clinic study found:

no statistically significant differences between bacteria counts onpre-wash and post-dry hands,

forced warm air dryers removed the most bacteria compared toother methods, and

there was no difference in germs removed from hands by using papertowels or forced warm air.

In the past 40 years, many studies have found that regardless of the hand washingagent used, electric air drying produces the highest and cloth the lowest reduction ofbacteria and viruses on washed hands. The studies showed the following:

Blowing warm air may lead to an accelerated dehydration of the skin surface,affecting the viability of the microorganism.

Warm air penetrates all the crevices in the skin versus towels that may not reachsuch areas.

Paper towels create unsanitary conditions even after use.

Unless paper towel waste is regularly cleaned, it can be a lasting source of bacteria.

There has been no evidence for the actual growth of bacteria or fungi inside thedryer, and

Bacteria counts are often 2 to 4 times lower inside the dryer than on othersurfaces in the restroom.

In public restrooms, perception of clean is as important as sanitation. Maintaining thisimage means keeping counters free of water and soap residue, keeping toilet tissuestocked, eliminating unsightly trash on the floor and ensuring any vandalism is repairedor prevented. Paper towel dispensers are commonly vandalized, with users breakingthe dispensers or opening them and removing large amounts of paper towels.

Hand dryers reduce these concerns:

They are well-built and very vandal-resistant. Features include tamper-proof screwsand small, round air intake holes to prevent access to any internal working parts. Thelack of buttons and moving parts provides less opportunity for tampering, and

Building owners and facility managers find that paper trash left on the floor isreduced, clogged toilets are basically eliminated and vandalism decreases.

High-speed hand dryers are louder than traditionalmodels due to air deflection noise, which is created bythe high-velocity, focused air flow bouncing off theusers hands. Depending on how close and at whatangle the users hands are to the airflow can fluctuatethe decibel levels up to the mid-90 decibel range.

The high-velocity focused airstream is what makes

these units fast and energy-efficient. If the flow of airis reduced too much to lower decibel levels, then youlose the high-efficiency performance of the unit, thusnegating the green benefits.

Some manufacturers offer models with a soundreduction nozzle option that lowers the decibel levelby 9db and eliminates almost all of the air deflectionnoise without sacrificing the speed and efficiency, byonly extending the drying time a few seconds.

Hand dryers are available in a number of cover finishes, including white and customcolor, chrome plated, bulk molding compound (BMC) and stainless steel. Somemanufacturers also offer custom digital image cover graphics, allowing buyers to designtheir own high-speed hand dryers with company logos, team mascots, school colors, andany other high-resolution image. These designs can include an optional green messagethat can educate the users as to why using high-speed, energy-efficient hand dryers isbetter for the environment than paper towels.

During the design and construction phase, theUSGBC and architecture firm Envision Designworked closely with green productmanufacturers to specify products that made

significant contributions to LEED criteria whilemeeting the classic aesthetic of the new space.

In order to meet rigorous LEED v3 guidelines,

all products were researched to verify theyrepresented the lowest environmental impactwithout sacrificing performance. This philosophyis echoed throughout our facility, including ourrestrooms that utilize high-efficiency plumbing

fixtures and high-speed, energy-efficient handdryers.

For nearly a decade, the high-speed, energy-efficient hand dryer has been a featured greenproduct in the USGBC headquarters restrooms.

Options for reducing energy have improvedsignificantly in the last ten years, said Ken Wilson,principal, Envision Design. High speed energyefficient hand dryers were specified at the USGBC

headquarters because they reduce waste and useless energy than typical hand drying accessories.Wilson specified a high speed energy efficient handdryer with a stainless steel cover that communicatesthe USGBCs commitment to environmental

sustainability. In architecture, performance anddesign are inextricably linked, added Wilson. thehand dryer we chose delivers both.

Both government and private organizations have designed materials performance andoperational requirements for green buildings. The restroom products discussed in thiscourse will contribute to the LEED program, and the Green Globes/Green BuildingInitiative (GBI). Some products in this presentation are also governed by the EPAs

WaterSense Program, another tool that guides green design.

The EPA WaterSense Program is similar to the ENERGY STAR Program that controlsenergy use of appliances.

Because there are many green programs, the EPA became involved to set standards ona national level, equalizing the requirements. To be certain that you are meeting localrequirements, follow local jurisdiction codes and relate that to the EPAs WaterSenseProgram.

The U.S. Green Building Council (USGBC) is a 501(c)(3) non-profit organizationcomposed of leaders from every sector of the building industry working to promotebuildings and communities that are environmentally responsible, profitable and healthyplaces to live and work. A whole-building approach encourages and guides a

collaborative, integrated design and construction process. USGBC developed the LEED(Leadership in Energy and Environmental Design) green building certification program,the nationally accepted benchmark for the design, construction, and operation of highperformance green buildings.

LEED credit requirements cover the performance of materials in aggregate, not theperformance of individual products or brands. Therefore, products that meet the LEEDperformance criteria can only contribute toward earning points needed for LEEDcertification; they cannot earn points individually toward LEED certification.
