A panel of noted plumbing engineers and designers discuss major issues in commercial plumbing: code revisions, compliance with the Americans with Disabilities Act (ADA), toilet parity and low-flush technology. Finally, they define what they feel are the major issues in commercial plumbing today in this month's M/E Roundtable.
As is the case with many health-care institutions, Kaiser Hospital in Sunnyside, Ore., periodically requires large amounts of steam for heating and sterilization. However, in the past, the difficulty was that one boiler was not sufficient to handle the sudden load swing. "In the wintertime, our two 300-hp fire-tube boilers would not hold the load, so we'd have to run our 500-hp boiler with a 30...
When the owners of ING Investment Products Group decided to build a new headquarters in West Chester, Pa., cabling infrastructure was a big concern. Recognizing the fast pace of technological developments and how difficult it is to avoid rapid obsolescence, they wanted a voice and data infrastructure that gave them not only reliable performance, but also longevity.
For high-tech, mission-critical companies like Townsend Analytics Ltd. of Chicago, a specialist in computer applications for Web-based finance, the ideal office is one where integrated building systems produce the right environment both for equipment and personnel. For its 11,000 square feet of space on the 19th floor of Chicago's 100 South Wacker building, the company was looking to integrate...
Magnetic-drive pumps are specifically designed to handle difficult fluids such as corrosives, pollutants, ultrapure liquids and toxics. This seamless pump can handle flows up to 1,500 gpm at 2,900 rpm and 1,760 gpm at 3,500 rpm. (Model ICM by Goulds Pumps) Circle 1 Structured cabling system doubles the bandwidth of the proposed category-6 standard, tested to perform at up to 400 MHz.
As this past Saturday marked the third anniversary of 9/11, anti-terrorism measures continue to be on the mind of the federal government. The U.S. Dept.
New research recently completed in schools provides additional insight into energy conservation, ventilation and indoor air quality (IAQ). The research utilized continuous IAQ monitoring technology, which measures temperature, relative humidity, carbon monoxide, carbon dioxide and odors and gases (TVOCs). Two comprehensive studies, conducted simultaneously in more than 100 classrooms in 11 Minnesota K-12 schools, will assist education professionals and decisions makers in all levels of state and federal government. Study Descriptions “Schools Air Monitoring Project for Learning & Energy Efficiency” (SAMPLE 2). The study was funded by a Minnesota public utility company as part of the State of Minnesota’s Conservation Improvement Program (CIP).
Penn State’s Department of Architectural Engineering has installed the first Internet-controllable lighting laboratory in the world, based on the digital addressable lighting interface (DALI). The DALI interface allows users from any PC and any location to control any lamp in this laboratory with a web browser; observe the effects with a web camera; and remotely monitor energy use and time-of-day use. Most recently, the control system was on display at Lightfair 2004 in Las Vegas.
The Speedway Club is a nine-story tower in a famous racing setting. It is located outside the first turn of the 1.5-mile main track at Texas Motor Speedway in Fort Worth. Both the Speedway and The Speedway Club are recognized as among the most modern in the world, and both are busy almost every day of the year. The Speedway hosted its inaugural NASCAR Winston Cup and Busch Series races in April 1997 and its first Indy Racing League and NASCAR Craftsman Truck events that June.
Creating and maintaining comfort conditioning in hospitals has long been the design goal and an operational requirement of HVAC systems, not only for patients and health-care providers, but also for equipment such as telephone rooms and computer rooms. Lately, it is becoming even more of a challenge. Most central air systems operate 24 hours per day, seven days per week to provide comfort conditioning and minimum air change rates as required by code. But the increasing use and need for digital communications, computerized patient records, digital radiology imaging and storage systems are creating an increasing need for year-round cooling in hospitals and related health-care facilities. Many new types of equipment are creating larger cooling loads: digital radiographic equipment such as computed tomography (CT) scan equipment and heat exchanger; cardiac cath lab and EP lab computer equipment, magnetic resonance imaging equipment, computer rooms themselves; and uninterruptible power supplies.
