Major developments regarding the antimicrobial properties of copper in such basic applications as doorknobs may lead to wider use of the alloy in the HVACR sector. The Environmental Protection Agency (EPA) has approved the registration of naturally antimicrobial copper alloys as a supplement to standard preventive measures in eliminating specific disease-causing bacteria.
In
the spring of 1994, two men witnessed their shared vision take root in the
inaugural assembly of many of the most dedicated commercial HVAC service
companies. The occasion was the first of 28 consecutive semi-annual meetings of
the Chiller Systems Group (CSG).
The ability to meet a fast-track, multi-phased construction schedule and energy-efficiency goals were critical factors in the selection of a modular central plant to air condition Chaparral High School in Scottsdale, Ariz. Beating the desert heat and quiet operation were also considerations.
With a lineup of speakers made up of two senators and three representatives as well as various government and business leaders, the Great Energy Efficiency Day event, put on by the Alliance to Save Energy (ASE) at the Dirksen Senate Office Building, showed that energy issues are top of mind on Capitol Hill and in the business world.
As 13 SEER came down the pike in 2006, contractors and distributors, operating on scattered timetables, took multiple approaches to preparing for the new industry requirements. Faced with yet another transitional challenge, the industry is making new efforts to prepare for 2010, the next step in R-22 phaseout.
The Chiller Systems Group (CSG) held its spring meeting April 17-19 at the Hilton Irvine/Orange County Airport in Irvine, Calif. The meeting was hosted by EMCOR Services Mesa Energy Systems and was attended by over 110 members and guests representing independent contractors from all over the United States.
The Mobile Classroom of Sustainable Technologies is a collaborative initiative sponsored by members of the mechanical and construction industries to promote environmental stewardship of building technologies through education and training.
Technicians quite familiar with terms such as EER and SEER may want to make room for yet another in the seemingly endless lists of industry acronyms: AEER. Emerson Climate Technologies is proposing annual energy efficiency ratio (AEER) as “a new measure for refrigeration applications.”
The U.S. Environmental Protection Agency (EPA) encourages use of technologies that drive the highest efficiency and the lowest emissions. Additionally, owners and builders must sustain and document performance over the lifetime of the application. In that context, optimal HVAC performance is critically important and it is possible while also reducing operational cost, raising efficiency, and minimizing environmental impact.
The University of Phoenix Stadium in Glendale, Ariz., has been subject of media hype since its opening in 2006 with such events as the Super Bowl, NCAA National Championship, Fiesta Bowl, National Football League games, and its designation as one of the “10 Most Impressive Sports Facilities on The Globe” by BusinessWeek magazine.
