View the full story, including all images and figures, in our monthly digital edition Back in the 1980s, when I was a computer science student, I was taught that a good systems designer would design him- or herself out of the system. This meant that the system worked, it was well documented, operators were well trained, and the system could be maintained. The system designer, like a house builder, could close the door on a project with a clear conscience and whistle while walking away, content with a job well done. In the world of energy efficiency, there's a word for that: persistence.

Students in Dennis Yuzenas’ American History classes at Bak Middle School of the Arts (MSOA) know a thing or two about the waterfree urinals.For instance, they know that each urinal installed at the West Palm Beach, FL School is saving up to 40,000 gallons of water per year. Mr. Yuzenas has told them so. He’s also taken time to explain the importance of water conservation and how critical it has become in southern Florida, as well as other parts of the country where the water shortages threaten the environment. “We discussed water free urinals as one example of a micromanaged approach to resolving our energy crisis--the idea being that thru proactive conservation we can limit our need to build more water and sewage plants.” Bak MSOA is one of several Palm Beach School District schools that have installed Falcon Waterfree Urinals.In 2004the school district made the formal decision to install water free urinals in all new middle and high schools.The district is also systematically replacing any older model urinal that uses more than one gallon of water per flush. The replacement project began with several pilot installations to test the effectiveness and practicality of the units.After reviewing the performance, savings, and other advantages, Lee Kapp, Utilities/Energy Manager for The Palm Beach County School District, became an enthusiastic proponent of water free urinals. “Naturally, we wanted the quickest payback, and that’s what we got when we decided to replace the old units, which were using 3 gallons per flush,” says Mr.

To see America’s technological future, scan the pages of any high school yearbook: girls and boys of every ethnic and social background with the potential to become the nation’s next generation of engineers, but who often lack the tools, motivation and guidance to get there. Now, a newly invigorated push from one of engineering’s oldest youth outreach programs, the Junior Engineering Technological Society (JETS), is stepping up to answer that challenge. Founded in 1950 to encourage young people to consider careers in engineering and technology, JETS offers academic competitions, mentor programs, educational materials and scholarships to increase the number of students in the career “pipeline.” Despite its long history, however, JETS organizers say that surging growth rates for science and engineering occupations, coupled with lagging numbers of students ready to fill those slots, has led to a full-court press to answer this urgent need. The result is a 56-year-old program retooled and revitalized to meet the realities of the new millennium and recently cited by Bayer Corporation as being among the country’s best STEM (science, technology, engineering and math) education programs for secondary students. JETS’ new thrust has been more than simply fine-tuning.

A single model plumbing code and a single model mechanical code for the U.S.? It could happen. Two major codes entities, the International Assn. of Plumbing and Mechanical Officials (IAPMO) and the International Codes Council (ICC), have held several informal conceptual discussions on combining their codes—the Uniform Plumbing Code with the International Plumbing Code and the Uniform Mechanical Code with the International Mechanical Code. So far, the consensus among all involved parties is that the meetings have been positive. Topics of discussion have included the differences in the processes and procedures the two entities use to create their codes and how these differences can be overcome. "Although we still have a ways to go, I believe our meeting has resulted in a much greater understanding of each other than we have ever had in the past," said IAPMO president Chris Salazar.

Background Harrah's Hotel and Casino has long been known as a leader in the hospitality industry. Built in 1988 with 468 rooms, Harrah's Laughlin has tripled in size to approximately 1580 rooms, 47,000 square feet of casino space, 8 food outlets, 4 banquet rooms as well as the largest arcade in Laughlin, Nevada. The Challenge Harrah's original Building Automation System was outdated and required constant maintenance. After careful consideration, the Engineering Manager decided to integrate the existing automation system with a more user friendly and non-proprietary solution.

If you've ever been to Austin, Texas, chances are you've seen the Westgate Building, one of the oldest high-rises in the city. Located adjacent to the State Capitol and Governor's mansion, the 25-story Westgate Building is home to numerous high-level attorneys and state legislators. In addition to the upscale condos, the building, which was originally built in the 1960s, also hosts a number of law offices, as well as a credit union. By the late 1990s, however, the building, despite its upscale location and lavish interiors, was experiencing a tremendous increase in the number of leaks from the metallic plumbing pipes - leaks which caused the need for ongoing costly, not to mention, disruptive repairs. "The building was literally a time bomb," explained Bill Fowler, president and founder of HHCC, Inc., the remodeling contractor chosen to solve the plumbing problem.
"For more than 25 years, we relied upon two huge cast iron boilers to get us through the harsh New England winters," said Gary Persechetti, Supervisor of Building and Grounds for Chelmsford High School. "When they gave out, it would have cost more to repair them than to replace them. A contractor from one of our construction projects introduced us to AERCO, who demonstrated the benefits of a modulating and condensing boiler." Persechetti was impressed by the demonstration, and in 2000 ordered five gas-fired Benchmark units from AERCO to support the school.
As part of an ongoing educational campaign targeting major conferences and tradeshows, the Construction Specifications Institute chose the U.S. Green Building Council's Greenbuild conference in Portland, Ore., last month, to launch its much-delayed MasterFormat revision. "It's not a revision," clarified CSI Executive Director Karl Borgstrom.
As long as HVAC systems use water as a means of heat transfer, engineers will continue to design variable flow systems to maximize efficiency. There are numerous combinations currently in use. Most common are primary-secondary, variable primary and variable flow with distributed pumping. Each system provides variable flow and a degree of system efficiency.
Osram Sylvania has been named an Energy Star Partner of the Year for the second year in a row, this time, for its outstanding efforts to reduce greenhouse gas emissions by making and promoting energy-efficient products. The award will be presented in March in Washington, D.C. Emerson Climate Technologies last month announced a strategic partnership between its Design Services Network and Global...
The Construction Specifications Institute (CSI) has announced the most significant revision yet to its MasterFormat. The Atlanta-based organization completed major content development for the 2004 edition and has already begun working with the AEC industry to transition from the current version. CSI will soon provide electronic and paper transition materials to assist MasterFormat 95 users to...
Punching in these words, I'm recovering from a pummeling. My beloved Bears, for the tenth consecutive time, were defeated at home by the hated Green Bay Packers. As if this weren't punishment enough, the game was broadcast nationally on Monday Night Football, exposing a pair of civic embarrassments—the misfits who masquerade as a professional football team and the "new" Soldier Field.
When thermal shock rendered boilers at North Springs High School inefficient and ineffective, Joseph Clements, coordinator of utilities services for Fulton County schools in Georgia, knew it was time for a change. Low-temperature water entering the gas-fired boilers had caused sooting in the combustion chamber and serious cracks in the refractories.
It's no secret that commercial, health and educational facilities all rely on boilers to provide hot water. What many occupants might not realize is that the water that comes out of their faucets is treated on-site to prevent mineral buildup in the boilers. The process of treating boiler water prior to heating has been around for decades.
Heating costs were mounting for the District of Columbia's school system, as were operation and maintenance problems attributed to the age and obsolescence of the district's boiler systems. Eventually, the school board realized that the problem had to be addressed, even though there wasn't enough funding to install new boilers in 13 target schools.
Since the discovery of a new pathogenic bacterial species in 1976, people have been seeking to blame someone, anyone, for the Legionella problems associated with plumbing and HVAC systems. Naturally, the designer of that total system is in the bullseye for the accusatory arrows. It is important for the consulting engineer to understand the problem and some of its causative aspects.
To aid in the development of high-performance, sustainable school buildings that use 30 to 50 percent less energy than conventional code-compliant facilities, the Washington-D.C. based Sustainable Buildings Industry Council (SBIC) has released a new guide.
When the domestic water-supply system at The John Hancock Center in Chicago began to show its age, the new pumping/control system that was installed did more than simply restore it to its original state. The system design improved the overall performance and versatility of the water-supply system, reduced maintenance requirements, provided dual-redundancy to guarantee continued operation and a...
One of the systems revisited at the plant was the sludge-handling system, which had gone through a number of changes and evaluations. An air dryer was added in 1991 to the air supply of the double-diaphragm sludge-press feed pump. Despite the fact that it was located inside the building, the pump would oc...
The new Bonide Chemical facility near Oriskany, N.Y., serves as proof that radiant heating can meet the most challenging heating requirements. This 150,000-square-foot building-with 2,900 cubic yards of concrete flooring and 40-foot-tall ceilings-will eventually house manufacturing, warehousing and office areas.
An extreme example of sustainable design, the new offices of the Chesapeake Bay Foundation just outside of Annapolis, Md., offer a long list of energy-efficient features—at an inflated initial cost.
Once Jack Dale Associates (JDA) quantified mechanical-system interactions for Texaco's data center, specified techniques were employed to upgrade the plant while avoiding disruptions to data-processing operations. Total construction costs for chiller-plant renovations commissioned by JDA were less than $600,000.
Refrigerant level sensors detect the presence of refrigerants at a specific point in refrigerant vessels, intercoolers and packaged chillers. Previously available only for ammonia, the single-point sensors and switches have now been developed for R-22, R-134a, R-404A and R-507.
