Volatile energy costs are making efficiency the watchword in HVAC systems design
More than two years ago, municipal utility Seattle City Light signed a two-year deal to supply electricity to all 38 Nordstrom stores in the state of California. However, the utility has refused to renew the deal, which expires in March 2001, "largely because we don't see a prospect of having surplus energy beyond our system requirements," a city official told The Seattle Times.

With one eye on the environment and the other on energy-efficiency, 18 government agencies, corporations and professional and environmental organizations from around the world have teamed up under the leadership of the U.S. Environmental Protection Agency (EPA) to form the Building Air Conditioner Climate Partnership.
Even though design-build activity continues to grow, a recent Zweig White & Associates (ZWA) survey concludes that there is little evidence suggesting design-build will ever become the project delivery method of choice in the industry.
As data centers, clean manufacturing and telecommunications come to dominate many an engineer's design work, unique issues are impacting heating, ventilation and air-conditioning (HVAC) systems. From air purity and cable management to thermal decay and fire suppression, mechanical designers must smooth technical snags and hold down installed costs.
