Products emphasize water savings in new and retrofit applications.
Official numbers from the U.S. Green Building
Council state 23,000 people attended last month’s Greenbuild
International Conference & Expo in Toronto. That number represents a decline of
5,000 people from last year’s Greenbuild in Chicago.
Still, this year’s lower announced number may sound high to several exhibitors
who expressed disappointment with light traffic during Expo hours. Greenbuild
2011, held Oct. 4-7, marked the event’s 10th anniversary and the first to be
produced outside the United States.
For some plumbing manufacturers, Greenbuild has grown in importance second only
to the Kitchen/Bath Industry Show. Unlike K/BIS, however, manufacturers
emphasize their products’ water or energy efficiency more so than style, color
and finish. They also display a much larger array of commercial products at
Greenbuild.
Plumbing products in Toronto generally could be divided into two categories:
those designed to conserve water on their own and those that can be retrofitted
into existing products to make them more water efficient. Both types are
expected to perform as well as models that use more water.
Water-Saving Showers

Australia-based
Caroma,
better known for its dual-flush toilets, introduced its first showerhead to be
sold in the United States.
The Flow high-efficiency showerhead, with a flow rate of 1.5 gpm at 80 psi,
includes a precision-engineered nozzle that pressurizes water to produce a soft
yet powerful spray, according to the manufacturer. It can save up to 10 gallons
more water than the standard 2.5 gpm showerhead for a 10-minute
shower.
Niagara Conservation Corp.,
another company better known for its high-efficiency toilets, displayed two new
showerheads, Sava and Tri-Max. Sava
showerheads feature a 4.4-inch-diameter spray head and 360˚ swivel for wide
coverage; they are available in 1.5 or 1.75 gpm flow rates. Tri-Max showerheads
feature a dial that delivers three flow-rate options: 0.5, 1.0 and 1.5 gpm.
Both Sava and Tri-Max are available in a chrome or white finish; feature a
non-removable pressure-compensating device to maintain constant water flow; and
come with a 10-year warranty.
Delta Faucet introduced new
round rain-can showerheads, which feature its H2Okinetic Technology.
The showerheads flow at 2.0 gpm, improving water efficiency by 20% from 2.5 gpm
models. Other shower products with H2Okinetic Technology are a body
jet with a flow rate of 1.8 gpm at 80 psi and two body sprays with flow rates
of 1.6 gpm or 1.8 gpm, both at 80 psi.
TOTO displayed its Legato Overhead Rain Shower, which uses TOTO’s
EcoPower technology to power its LED lighting. Along with using the kinetic
energy of flowing water to power the electronics, the Legato system
incorporates TOTO’s Shape Memory Valves, which prevent leaks and
drips.
Moen offered its new
WaterSense-labeled Eco-Performance showering
systems with a wall-mount or handheld showerhead, or a combination of both. The
company exhibited its new Commercial Slide Bar Grab Bar system, which includes
an Eco-Performance handheld showerhead with an ADA-compliant grab bar.
Flush Valves, Urinals, HETs

Moen
Commercial’s M•Power
line of sensor-operated flush valves can save energy via an infrared sensor
beam that activates a flush cycle only when a user is in range.

Moen’s Commercial Division also introduced its M•Power line of
sensor-operated flush valves featuring standard-flow (1.6 gpf for toilets/1.0
gpf for urinals), high-efficiency (1.28 toilets/0.5 urinals), dual-flush
(1.6/1.0 for toilets) and pint-flush (for urinals) models. These flush valves
(pictured on Page 18) can save energy via an infrared sensor beam that
activates a flush cycle only when a user is in range. Their available power
options include standard AA batteries and low-powered AC
adapters.
American Standard promoted its
34 pairings of commercial urinals, toilets and flush valves designed to make
specifying more efficient, while yielding a combined savings over the
individual component prices for wholesalers and contractors. The toilet
fixture/flush valve combinations include standard 1.6 gpf or 1.28 gpf
high-efficiency toilets.
The company’s standard urinals are available as 1.0 gpf models as well as
high-efficiency urinals that flush 0.5 or 0.125 gallons, yielding 50% and 87% water
savings respectively over standard units. At Greenbuild, American Standard
introduced its Decorum, an HEU with FloWise technology that uses 0.5 gpf, which
is 50% less water than a standard urinal. It also features the EverClean
permanent finish, which inhibits the surface growth of stain- and odor-causing
bacteria, mold and mildew (see photo on Page 17).
Sloan displayed its full line
of high-efficiency vitreous china toilets and urinals, including its Waterfree
Urinal. A sealed cartridge eliminates the need for water, typically conserving
40,000 gallons per unit per year.
Sloan also exhibited its solar-powered SOLIS flushometers, which are equipped
with Smart Sense Technology. For urinals, the Solis flushometer can reduce water
usage up to 80% over standard sensor models.
Delta Faucet says it has been producing flush valves for years and displayed
its latest manual and electronic models at Greenbuild. These included
dual-flush models and electronic flush valves featuring H2O
Optics.
Caroma showed its Invisi Series II wall-hung toilet with the plumbing hidden
inside the wall to create a more spacious look for bathrooms. The dual-flush
HET has a button for a half-flush, which uses 0.8 gpf for liquid, and one for a
full flush, which uses 1.28 gpf for solids, for an average flush of 0.9
gpf.
Zurn Industries passed out
pint-sized beer glasses at its Greenbuild booth to promote its Nano Pint 0.125
gpf ultra-low consumption urinal system. Part of the compay’s EcoVantage line
of water-saving products, Nano is equipped with a sensor-operated flush valve.
Faucets And Sinks
Kohler unveiled
two advanced commercial faucets that comply with new low-lead regulations: the
Gooseneck and Streamlined. The faucets feature a no-touch design that utilizes
the company’s proprietary Insight adaptive infrared sensor technology, which
runs off Kohler’s 30-year Hybrid Energy System.
Sloan introduced its BASYS platform of sensor-activated faucets that offer four
power options, including alternative sources using turbine or solar technology
(see photo on Page 17). BASYS features three spray modules, five body types and
four crowns with external diagnostic LED indicators.
Hansgrohe showed its line of
1.5 gpm faucets, including electronic models.
Component Hardware Group
displayed its Sidekick electronic faucet with an infrared wave-on, wave-off
sensor. With the sensor’s placement on the side of the unit, the faucet can be
used by doctors scrubbing for surgery or in food-service
applications.
American Standard’s Nightingale ICU sink can be used in hospital settings as well.
Its exceptionally deep bowl helps to manage the splash of water from the
faucet.
Bradley Corp. exhibited an
individual-sized version of its Verge Lavatory System for commercial applications.
Made of recycled material, the lavatories don’t have a sealer and don’t have to
be sealed every year. Bradley also showed its OmniDeck lavatory made of the
same material but with an undermount
sink.

Neoperl showed its 1.0 gpm
pressure-compensating aerators for bathroom faucets. The aerators can reduce
the flow from 2.2 gpm and still provide a full flow of water.
Encore, a division of
Component Hardware Group, introduced its ONE-TAP Metering Aerator for converting
a standard faucet into a low-flow metering faucet. It fits most faucets with an
existing aerator and provides up to 87% water savings over conventional
faucets.
Niagara exhibited four new aerators: Versa
Kitchen, Tri-Max, Lead-Free and Bathroom Sink. All models can be used on
existing faucets to achieve water and energy savings without sacrificing
performance and convenience.
Moen displayed its Eco-Performance aerators for kitchen faucets and service
kits for pulldown/pullout faucets. The aerators can be used on a number of
Moen’s collections and fixed-spout faucets. Each aerator or service kit
provides consistent flow while maintaining water pressure. Each features a flow
rate of 1.5 gpm vs. the standard 2.2 gpm, which provides up to a 32% water
savings.
Zurn showed sensor products that can be used to replace manual handles on flush
valves. The company also showed its siphonic roof drains that drain water from
roofs much quicker than conventional drains.
Dahl exhibited its dahl-ECO line of valves, which incorporate a durable
patented alloy called EcoBrass. The corrosion-resistant valves exceed lead-free
requirements based on California AB1953 and Vermont S-152 legislation, and
surpass any low-lead standards worldwide.
