Environmentally sound bathrooms on college campuses use revolutionary XLERATOR Hand Dryer.
�Greening� the Student Union.
Student Union at CalState Northridge leads
the way towards hands-free, environmentally
sound bathrooms on college campuses.
Southern California is almost as well known
for its environmental conscientiousness as it
is for its frequent water shortages. In a part
of the American landscape once dominated
by arid desert, the now densely populated
region has had to find new ways to preserve
its important water resources. The University
Student Union at California State Northridge
has met this environmental challenge headon.
Several of the newly-renovated Student
Union buildings boast the most hands-free
�green� state university bathrooms in the
country. All of the University�s Student Union
renovation projects in the last decade have
been undertaken with environmental
soundness and water preservation in mind,
and the energy-saving measures have, not
surprisingly, saved the University a great deal
of money in the process.
Gary Homesley, Assistant Director of Facilities
and Maintenance at the Northridge University
Student Union, says that the environmental
initiative began with the former Assistant
Director, Ray Miller � and they both agreed it
was the logical thing to do. �After all,� says
Homesley, �in the state of California it only
makes sense to be water and landfill
conscious.� Plus, they
knew that an environmentally-friendly (and
money-saving) student union complex would
be a popular selling point for incoming
students. �We�re a nonprofit organization, and
this way, we let students know we care about
their money. They�re very supportive of our
efforts.�
Together, Homesley and Miller discussed how
best to achieve green standards and save
money amidst budget cuts and other
challenges to new development. Homesley
knew that water preservation would be a
major factor in cutting costs. �In California,
you have to pay a sewer tax on all domestic
water that you use,� he explains. �So,
naturally, the less water you bring into a
building and then waste in the sewer system,
the fewer charges you incur.�
To start, Homesley and Miller tested several
waterless urinal systems to save water in the
student union men�s rooms, both agreeing on
the Waterless No-Flush� urinals from C&L
Supply Company. These urinals work by
draining fluid and trapping odors beneath a
special sealant, which is poured into a small
cartridge below the drain. The cartridge traps
and filters out sediment, allowing an
unobstructed flow of liquid down the drain
without wasting water. The first building
Homesley outfitted has 30 restrooms, 13 of
which are men�s rooms with urinals. Once
installed, the Waterless urinals alone accounted for a 35% reduction
(around a million gallons per year) in
domestic water intake that saved the
university between $10-15,000 a year,
depending on the annual cost of water.
Homesley was pleased at the results and
immediately started looking into other
green fixtures: �Once we saw how effective
the water-free urinals were at saving water
and costs, we wondered, what next?� He
installed hands-free faucets with automatic
shut-off, automatic soap dispensers, and
automatic flush toilets in all 30 restrooms.
The automatic fixtures provided a more
sanitary touch-free environment, as well as
limiting the amount of water and soap
product used.
Next, Homesley decided to look at hand
dryers. He wanted to reduce the $21,000
spent annually on paper towels, installation
labor, and trash hauling fees. In addition to
the expense of paper towels, the
environmental impact of their manufacture
is significant: to make one ton of recycled
paper uses 7000 gallons of water, 360
gallons of oil, 158 million BTUs of energy,
and releases 86 pounds of pollutants into
the atmosphere. Homesley knew that he
would have to limit paper use to achieve a
truly green bathroom. However, he was
skeptical. �I�d never liked hand dryers in the
past,� Homesley said. �They never seemed
to work well enough; your hands were never
actually dry after using them.�
Enter the XLERATOR� hand dryer. Researchers
at Excel Dryer found that water clings to skin
both as a thin film and as loose droplets.
Instead of trying to evaporate the droplets,
XLERATOR� blows them off using a focused
high-velocity air stream and a specially
designed nozzle. The high-velocity air also
breaks up the layer of water vapor between the
air and the skin. This causes the thin water film
to evaporate more quickly than it would using a
conventional dryer. Thus, it dries hands in
about 15 seconds and uses 80% less energy
than other dryers. �I was very impressed with
these units,� confirms Homesley. �They are the
best dryers I've ever seen, and one of the most
energy efficient units on the market. I decided
to get rid of all of our paper towels altogether."
Homesley says that the cost of installing the
urinals and dryers added up to about $24,900
total (all installation was done in-house with a
fixed overhead). He started seeing significant
savings due to water conservation within less
than one year, and now estimates that the
XLERATOR� and Waterless No-Flush� urinals
save the Student Union more than $30,000
every year � money that used to be spent on
water, paper towels, and associated labor and
disposal fees. �The Union bathrooms generated
about six tons of paper towel waste every year,�
says Homesley. �It�s remarkable to be able to
cut that out.�
The student union now consists of 248,000
square feet on nine acres of property. Out of
the seven present buildings comprising the complex, three
boast bathrooms that incorporate as many
LEED credit qualifying systems as possible.
In Homesley�s view, the 30 bathrooms in
the union building are now 100% green.
They use only biodegradable toilet paper
and no paper towels at all. They have
significantly cut back on overall energy use.
They replaced electrical water heaters in the
building with natural gas, connecting
directly to an existing central plant at the
Student Union. All facilities were centralized
wherever possible, rather than building new
systems such as rooftop heating units. They
use only efficient lighting such as energy
watt and compact fluorescents, eliminating
incandescent lamps wherever possible. All
systems in the building � including air
conditioning and lighting - are monitored
electronically via photo and motion sensors.
Homesley even limited much of the
landscaping around the union building to
native plants that don�t require much water.
Homesley expects that, by the end of the
fiscal year, two more buildings should be
completed � and he plans to continue to
adhere to strict green standards. �This has
been a real whirlwind experience for us for
the past few years,� he says. �We had a lot
of success retrofitting the older buildings,
once we tested and implemented suitable
products; I expect to continue with this
trend.�
