Self-cleaning Turbo-Disc Filters are designed to remove particles and other contaminants from cooling water, complementing the water-treatment program by keeping heat transfer surfaces clean, which results in lower energy costs for the building. All models come with a 2-inch backwash line, eliminating the need for large flush line piping and floor drains, which often are required by conventional sand filters.

Window film moderates classroom temperature and creates a more comfortable learning environment
Bekaert Specialty Films
In September 2005, the average recorded room temperature at Fair Haven Grade School, Fair Haven, Vt., was 95°F. The uncomfortable climate was creating a roadblock to students and teachers, and needed to be addressed immediately.
The school's facility manager, Elmer Jones, contacted a Solar Gard Window Films dealer to request an assessment of how to better control the heat in the school. The dealer recommended the school install Solar Gard Silver 20 window film to lower the temperature on the school's east-facing windows.
“As expected, the temperatures dropped dramatically in the classrooms, and the solar glare was reduced,” says Jones. “Another surprising and significant benefit that the teachers commented on was that the hue, or the color tint, had a remarkable calming effect on the children.”
Jones, along with the school's principal, requested the west side of the building be treated with the window film to achieve the same effect. The original job was for 85 windows, but in the end, 146 windows were retrofitted.
The immediate benefits of reduced hot spots and glare, improved comfort and balanced climate at Fair Haven Grade School have led a neighboring school to install the window film as well.

Upgrade enables IT department to monitor and troubleshoot network that links five campuses
College of The Albemarle in northeastern North Carolina uses Network Instruments' Observer to manage the network that links its five campuses together. Observer probes monitor frame relay links, the student VLAN, the DMX port for online courses, and both sides of the firewall.
“Observer caught my eye because all of the features were already built in, and it fit within my budget,” says Wayman White, network administrator. “By deploying Observer probes throughout the system, I always have a global picture of how my network is doing.”
This detailed insight into campus activity became crucial as the college's network began supporting registration, online classes, academic blogs and career guidance.
“So much of the college's livelihood is dependent on the network these days,” says White. “If the network goes down, productivity goes down, and that's money out of the college's pocket.”
A surge in network usage recently threatened the college's services. Observer showed a spike in bandwidth utilization, and a packet capture revealed 100 machines pointing back to one machine. From there, White quickly located and disconnected the offending system.

Numerous leaks prompt school to install new roof system while in session
Performance Roof Systems
Timbers Elementary School, Humble, Texas, was overwhelmed with roof leaks. The school year had not yet ended, but with the numerous leaks, the school had to begin replacing the roof system immediately while classes still were in session.
The roof system being replaced consisted of a three-ply, built-up roof (BUR) system with a loose gravel surface. The crew had to vacuum off the gravel prior to removing the BUR roof.
The combination of a 10-man crew and the unique labor-saving benefits of a Permastic spray application enabled workers to tear off and replace an average of 4,000 square feet of roof area per day. The crew installed a Derbigum GP membrane, along with an additional Derbicolor membrane using the same Permastic spray application, which provided an additional waterproofing layer.
To ensure the roof was watertight at the end of each day, all layers of the system were heat welded at the side and end laps with an automatic hot-air welder. Open flames were completely eliminated with the use of the hot-air welder, which provided a safe job site for both workers and building occupants.
It was crucial to remove debris daily and place it in safe dump boxes in an area inaccessible to children. The tear-off equipment had to be staged away from the playground and surrounding area to ensure the safety of children during recess and to prevent interruption of scheduled activities.

Electric utility vehicles save college money in initial costs and long-term maintenance
Schoolcraft College, Livonia, Mich., has a 125-acre campus with multiple classroom and administrative buildings, a physical-education complex, a technology center, and expansive grounds and parking facilities. More than 8,000 students and professionals access the campus daily.
The college's staff of plumbers, carpenters, HVAC specialists and troubleshooters ensures that the campus functions efficiently. To assist with their duties, these employees rely on a wide variety of tools and equipment, including a fleet of electric-powered utility vehicles from Club Car.
“They work really well around campus,” says John Wright, director of maintenance and grounds. “They're quiet and easy to drive. We also really like their ease of maintenance, and they seem to be large enough to handle all of our tasks.”
The college purchases new utility vehicles every seven years.
“That's basically one battery change,” says Wright. “We replace the battery once during the seven years, and when the second battery is ready to replace, we get a new vehicle.”
According to Wright, each Club Car vehicle costs $4,000 to $5,000 less than a small pickup truck.
“The larger savings is on maintenance, because Club Cars are much simpler, and they're designed for short runs,” he says.
Electric utility vehicles don't require oil changes, fuel, spark plugs, transmission fluid changes or coolant changes.

No-water urinals help district save on utility and labor costs
Falcon Waterfree Technologies
Bak Middle School of the Arts, West Palm Beach, Fla., is one of several schools in the Palm Beach School District that have installed Falcon Waterfree Urinals. Each urinal installed at the school is saving up to 40,000 gallons of water per year.
In 2004, the school district decided to install no-water urinals in all new middle and high school buildings. It also is systematically replacing any older-model urinal that uses more than one gallon of water per flush.
“Naturally, we wanted the quickest payback, and that's what we got when we decided to replace the old units, which were using three gallons per flush,” says Lee Kapp, the district's utilities and energy manager.
Another benefit of the no-water urinals is a reduction in restroom vandalism. Because no-water urinals are not flushed, foreign objects such as paper towels or gym socks can't clog the system. This means fewer bathroom floods, as well as savings on maintenance and replacement of traditional urinals. The units also are virtually impossible to damage.
Maintaining the no-water units is no more labor-intensive than maintaining a regular urinal. School custodians wipe down the urinals with a recommended cleaner as they would any other type of urinal. Replacing the cartridges takes only a couple of minutes and is only required every 7,000 uses in typical installations. The district's plumbers have added this minor task to their routine maintenance procedures.
