Greenbuild International Conference and Expo just continues to grow. Proving that last year's impressive attendance was no fluke, the U.S. Green Building Council (USGBC), the show's sponsor, said attendance for the 2008 event, held Nov. 19-21 in Boston, was just over 28,000 — an increase of about 20 percent over 2007. That's big....
HPAC Engineering's fifth annual Engineering Green Buildings (EGB) Conference and Expo, co-located with the magazine's inaugural Commissioning Green Buildings (CxGB) Conference and Expo and the NV Energy Sure Bet Program conference and regional-partner exposition, brought approximately 300 building professionals to Las Vegas. ...

One of the most rapidly accelerating trends in the commercial-buildings industry — driven by rising energy costs and the growing influence of the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) Green Building Rating System — is the use of water-source-heat-pump (WSHP), or thermal-energy-transfer (TET), systems. ...
Although air is not cooled by movement alone, it can create a cooling sensation as it passes over a person's skin. The proper use of air movement, then, can increase occupant satisfaction. It also can improve energy efficiency, as substantial savings can be realized by destratifying heated air in spaces with high ceilings during cooler months. ...
Many system-design ideas that have been proved in commercial buildings, such as parallel pumping, can be applied to industrial facilities. Parallel constant-...
Applied rooftop heating systems offer many performance and cost benefits, including configuration flexibility, energy efficiency, and wide operating ranges, for owners and design engineers. The availability of fully modulating gas heating systems with high turndown ratios helps maintain comfort conditions. ...
Unlike other building systems, it is virtually impossible to test an atrium smoke-control system to design conditions. This primarily is because design...
Uncontrollable changes both inside and outside of a building can impact efforts to maintain a desired temperature. Changes in occupancy, lighting and...
The performance of variable-frequency drives (VFDs) can be compared with that of other methods of volume control quickly and simply. All that you need...
Motor For mid-range fractional-horsepower applications, the ECM 142R motor is an energy-saving solution for split-system outdoor units, package units,...
Bruce T. Halle Library on the campus of Eastern Michigan University (EMU) in Ypsilanti, Mich., has a number of air-handling supply and return fans of varying size and belt configuration. EMU was unable to shut off those fans reliably at night to save energy because of the possibility of the belts being thrown off of their pulleys upon startup. Indeed, belt slip necessitated continual retensioning. ...
