Mesa Public School District #4 is the largest school district in the state of Arizona. It boasts over 70,000 students in over 100 campuses scattered over 200 square miles. Because of rapid growth, Mesa Schools, like many other districts across the nation, were forced to utilize modular classrooms for two reasons.
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.
Shipments of lighting fixtures in the U.S. are expected to rise over 5% annually through 2008 to over $14.4 billion, according to Lighting Fixtures , a new study from The Freedonia Group, an industrial market search firm. This pace represents a significant acceleration from the 1998-2003 period as improving economic conditions boost demand in both construction and manufactured goods markets. Advances in lighting fixture demand will also be supported by an ongoing focus on energy efficiency, which will lead to residential remodeling activities and nonresidential retrofit projects aimed at increasing the energy efficiency of existing lighting systems.
Chicago’s Palmer House Hilton needed to replace its cooling tower and called on industrial and commercial HVAC firm Team Mechanical, Inc. (TMI) to aid with the purchasing and installation of the tower onto the roof of the 24-floor hotel. TMI worked with Maddock Industries to purchase the new $250,000, 112,000-lb.
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).
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.
The International Code Council (ICC) voted unanimously in June to amend its International Fire Code (IFC) in order to permit electronic monitoring of fire extinguishers in lieu of 30-day physical inspections. According to the ICC, 32 states use the IFC. Utah was the first state in the nation to adopt standards for the electronic monitoring technology. Moreover, state fire marshals in Maine, Nevada, New Hampshire and New Jersey have also given the go-ahead for occupancies to install such equipment while the necessary code changes are in process. The new code language, which is endorsed by the National Association of State Fire Marshals (NASFM), does not mandate the use of electronically monitored fire extinguishers; instead it allows its use as an alternative to thirty-day physical inspections.
