HVAC experts should know something about radiation and it’s control for a variety of reasons. First, planning and designing effluent systems for laboratories and other industrial facilities requires some knowledge of this hazard and how it is used. Secondly, maintenance and repair of these systems will require some near contact with potentially contaminated components such as fume hoods, blowers, flow dampers and ductwork.
A school district’s biggest expense after payroll is its utility bill. Because the HVAC system is a major component of a school’s utility bill, careful evaluation of a school’s HVAC requirements and equipment options can help administrators save money while actually improving learning productivity. Every school is different, so there is no one HVAC solution for all schools. Instead, there is a “best” solution for each individual school—chosen from careful evaluation—that maintains the highest possible indoor air quality at the lowest possible energy costs.
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 Hydraulic Institute (HI), Parsippany, N.J., has just added two new standards to its ANSI/HI Pump Standards: the American National Standards for Air Operated Pumps (ANSI/HI 10.1-10.5-2004), and the American National Standards for Air Operated Pump Tests (ANSI/HI 10.6-2004). Air Operated Pump Standard This new standard is for air operated pumps, including positive displacement reciprocating pumps used for general liquid transfer, which are driven by means of compressed gas (usually air) from an outside source. The pump may be designed with a single diaphragm or double diaphragms connected to a reciprocating shaft in which one side of the diaphragm is in contact with the liquid being pumped, and the other side is in contact with the compressed gas (air). The standard includes the following sections: • Types, Configurations and Nomenclature• Definitions• Design and Application• Installation, Operation and Maintenance Air Operated Pump Test Standard This new standard applies to the test of air-operated diaphragm and bellows pumps.
As one of the founding teams in the league that would become the NFL, the Chicago Bears are steeped in traditions that run deeper than most. The roster of retired Bears jerseys on display in the lobby of the team headquarters is awe-inspiring, the names timeless: Blanda, Butkus, Ditka, Payton, Sayers. The faithful converge on Soldier Field every home Sunday, win or lose, to shiver in the open air as the wind howls off Lake Michigan. Even the stadium itself, until recently a crumbling Greek temple with peeling plaster and questionable plumbing, has been part of the team’s mystique for more than 30 years. In such a franchise, change does not come easy.
For more than three decades, the Natural Resources Defense Council (NRDC) has been a leading voice for environmental advocacy in the US. When the group decided to open a regional office in Santa Monica, California, they knew it had to be environmentally friendly. The building, named for Robert Redford, actor and long-time environmentalist, would combine cutting-edge technologies and materials with energy-efficient architecture to create a showcase for green-building design and promote environmental activism. The building, extensively remodeled by the NRDC and opened in November 2003, pushes the envelope for environmental design and construction techniques.
