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.
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.
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).
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.
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.
