Improving IAQ
Team-cleaning system revives learning environment
ProTeam. Lake Braddock Secondary School, Burke, Va., is a 533,660-square-foot facility occupied by more than 4,000 students, faculty and staff. Teachers and staff complained that the school was a “sick building.” They pointed to higher than normal absenteeism and aggravated allergy attacks as the symptoms.
In 1998, the school was selected for an unpublicized test of a team-cleaning system that uses ProTeam's direct suction backpack vacuums in an aggressive daily vacuuming regimen. Within two weeks of the new cleaning program, faculty and staff were asking custodians and building administrators what they had done, applauding them on the cleanliness of the building and air.
A parent of an asthmatic student said that her son required much less of his inhaled medication after the cleaning system was used. Staff absenteeism also was much lower. The final indicator of the improved filtration efficiency was that the frequency of dusting, which had been a daily chore, was required only three times a week.

Letting off some steam
A steam trap survey can help locate steam leaks and reduce costs.
Ultrasonics. Duke University Medical Center selected a consultant from Enercheck Systems to conduct a steam trap survey using the Ultraprobe 2000.
Steam can escape through external or internal leaks in fittings, valves, traps or particular control devices. Blowing or leaking traps may cause a high back pressure in condensate piping. Failed control valves may cause excessive condensate load. When control valves are oversized, they are forced to work in close tolerance to the disc and seat.
Fluids moving from the high-pressure side of a valve to the lower pressure side produce turbulence. This generates ultrasound, which an ultrasonic detector translates into an audible range for the human ear. The ultrasounds are heard through headphones and viewed as intensity increments on the handheld instrument's meter. High frequency tuning allows the user to adjust for differences in fluid viscosity and reduces interference from stray pipe noises.
Every aspect of the steam system throughout each building of the research facility was inspected comprehensively. At each site, the consultant found where the steam line entered the building and traced the system. The consultant checked to see if pressure was controlled correctly and whether relief valves were blowing steam through the roof. In the end, 2,100 steam traps were found.
The ultrasonics-based steam and maintenance program resulted in savings worth $250,799 the first year it was used. This translates into 37 million pounds of steam saved when compared to the previous year.

Sound isolation
Acoustical door keeps music in and noise out
Wenger Corporation. The School of Music at the University of Louisville, Ky., wanted to improve the sound isolation in one of its rehearsal rooms — a double studio large enough to hold 20 to 25 musicians. Sound isolation was particularly critical because Wenger previously had installed its V-Room rehearsal system inside the room with sensitive technology that can simulate the acoustical responses of different environments, including the university's major performance/recital hall.
“If you're a musician concentrating on making music, you only want to hear what's happening in your environment and nowhere else,” says Herbert Koerselman, dean of the School of Music. “The door has been a great help in reducing or eliminating any extraneous noise.”
The acoustical doors offer unique features that improve performance, including a continuous cam-lift hinge that provides an uninterrupted gasket seal and eliminates potential pinch points. The door's isolated-crimp construction incorporates a neoprene gasket between door faces to minimize sound transmission. Dual magnetic seals provide multiple seal points to minimize sound leakage, and the door leaf's four-sided frame provides superior rigidity and sealing properties.

Saving energy
Energy service company helps university develop plan to reduce operating costs
Vestar, Inc. In an effort to reduce energy and operating costs and improve its learning environment, Ohio University, Athens, sought guidance from Vestar, Inc., an energy service company specializing in facility and infrastructure solutions.
The project was divided into five phases and was designed to be carried out over five years; the first phase began in 2000. Energy-conservation measures include lighting-fixture retrofits and redesign; occupancy sensors; central district heating system modifications; control system expansion and enhancement; and toilet, showerhead and faucet retrofit and replacement.
The Vestar program also includes training, and a campuswide occupant energy awareness and communication program.
Upon completion, the project will save the university an estimated $2.5 million annually, which will be used to pay for the project over 10 years. The project also will replace aging building systems, allowing the university to avoid more than $10 million in capital expenditures over a 10-year period.
Phase 1 of the project is now complete, and according to the achieved annual savings report, it has exceeded the projected savings outlined in the initial contract.

A clean approach
Planning for healthier environments at a lower cost
Johnson Controls. Mounds View Public Schools, Minn., faced recurring air-quality problems associated with deferred maintenance. Short-term efforts had been made to correct the problems, but pressure from parents and the community moved the district to resolve the IAQ problems long-term and to address other facility improvements.
Jan Witthuhn, superintendent of the district, says “We looked to Johnson Controls, due to their trusted expertise, to evaluate the plan, tailor the solution and determine a way that we could afford it.”
A lifestyle program-management approach enabled technical and financial aspects of the solution to be addressed. When a bond referendum fell short of providing the $52 million needed for the district's facility renovation, Johnson Controls negotiated with the state to get levy authority for the project's funding.
As part of the program-management process, Johnson Controls continually looked for ways to add value. By reviewing the engineer's plans, the company sought to eliminate upfront project costs without increasing life-cycle costs.
These efforts have resulted in $10 million savings. Life-cycle cost-saving measures are projected to provide annual energy savings of $1.3 million. The IAQ renovations, which are designed to maximize utility rebates, will result in more than $600,000 for the district.

Maintenance solution
Automatic flushing devices clear the air in district elementary schools
Technical Concepts. The custodial department for Independent School District 1, Tulsa, Okla., reported a problem within its 55 elementary schools: unflushed toilets. Complaints came from parents and teachers throughout the district. As solutions were being considered, one of the district's elementary schools financed and arranged for the handles on all toilets to be replaced with automatic flushing devices, which solved the problem.
When voters approved a bond issue for upgrading bathrooms within the school system, the funding was used to retrofit toilets and urinals. The district decided to use AutoFlush units from Technical Concepts, which took about two minutes each to install.
The AutoFlush solved more than one problem for the district. The city's hard water was leaving a ring in toilet bowls when they weren't used during breaks and holiday weekends. In the hot summer months, the water slowly would evaporate, leaving a series of rings in the bowls. Because the AutoFlush is programmed to activate every 24 hours whether or not the toilet has been used, calcium deposits no longer cling to the toilet bowls. The daily flushing also eliminates the problem of the water drying out in catch basins during the summer months — a problem that previously allowed sewer gases to enter the bathrooms.
The positive results of these installations prompted the district to install AutoFlush units at 40 additional sites, including the district's middle schools, high schools and administrative offices.

Protecting sensitive equipment
Surveillance console secures digital technology
Middle Atlantic Products. Ben Davis High School in Wayne Township, Ind., has recently completed a $1.5 million electronics upgrade for its security control room. With so much money invested in digital equipment, the school had to find a cost-effective console to house the sensitive equipment.
The Quiet-Cool Series surveillance and monitoring console allows the district to deliver a modern facility that can be operated in a cost-effective way. The console's ability to remove hot air and increase the flow of cooler air was a key factor in the selection process. With such a diverse monitoring and recording job to do, the sensitive heat-generating monitors and digital recorders have to remain operational at all times.
“We've never had a systems failure due to heat because the active cooling component works so well,” says Chuck Hibbert, director of safety and transportation for the Metropolitan School District of Wayne Township, Ind.
The four-bay security console houses monitors that help the operator run the entire system. While the computer monitors in the console watch the system, the video displays from the cameras and digital video recorders are viewed on a large projector screen. The console's ergonomic design allows a single operator to access all control parameters.

Roof replacements
Roofing system offers puncture resistance and waterproofing
The Garland Company, Inc. The West Contra Costa Unified School District, Calif., has replaced the roofs at each of its five high schools since 1994. Together, the projects encompass more than 200,000 square feet of roof area.
The district wanted a cap sheet that was strong and puncture-resistant, and a waterproofing layer for the new roofs. The Stress-Ply E modified bitumen roofing system was used to serve both of these purposes for one price.
The projects' typical timelines were compressed from a standard three months to six weeks. Gary Freschi, director of buildings and grounds for the district, credits on-time, in-budget completion to “using the best materials, design teams, workmanship and quality control available.”
The roofs are expected to last 40 or 50 years with minimal maintenance.

Reducing legwork
Multi-function technology reduces the need for manpower
Belimo. The California State University — Fullerton campus encompasses 223 acres and 20 primary buildings, so when a technology was introduced that could reduce the legwork of its facility personnel, the university became interested.
MFT and its line of actuators give facility engineers greater flexibility when it comes to actuator control. An MFT actuator can be configured to match any control application, making it ideal for retrofits and facilities with older pneumatic control systems.
With MFT, one actuator can be programmed for either floating point or proportional control and achieve feedback using either signal. Each MFT actuator can be field programmed for different signals, including VDC ranges, PWM, and 4 to 20mA output. This field-adjustable flexibility reduces the number of replacement actuators that must be in stock and makes actuators interchangeable throughout the system.
The CSUF engineering staff chose to test Belimo's Multi-Function Technology (MFT) at Pollak Library. Craig Newton, the chief engineer at CSUF, says he decided to try the MFT actuators because of the floating-point control with feedback.
The Pollak Library HVAC system included many tri-state (or floating point) reheat valves. The difficulty with these valves is determining their position if a problem occurs. For instance, if the reheat valves were not warm enough in a space, facility personnel would have to go to the building and touch the pipes to determine if the valve was open or closed. Control with feedback saves them a trip.
The university now has standardized on Belimo valves and actuators.
