Waxman-Markey, cap and trade, smart-grid infrastructure, real-time pricing, demand response, on-site energy storage — never has there been a more fascinating — or challenging — time to pursue the field of energy or facility management, as we are experiencing the convergence of three long-gestating trends that will forever change the way we purchase, manage, and consume energy....
The U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) Green Building Rating System provides many paths to certification, some of which result in a more energy-efficient building than others. Thus, just because a building is LEED-certified does not mean significant opportunities for energy savings cannot be found. As the case studies at the end of this article show, savings usually can be had for little or no capital investment by fine-tuning the operations of a building. ...
Amid the current push to “go green” by building high-efficiency, environmentally sound, sustainable HVAC systems, heat pumps — particularly those that use the earth's geothermal energy to serve as a heat sink and source — are generating a lot of buzz. Ground-source heat-pump (GSHP) systems operate like every other HVAC system: They move energy from one place to another. Although that sounds simple, HVAC engineers and designers owe their livelihoods to the complexities. ...

During the fall of 2008, Jimmy Hughes, owner and president of Hughes Bro. Inc., was in the process of bidding a potable-water-piping job at a 65-room, four-story Comfort Suites hotel in Nashville, Tenn. With copper prices at an all-time high, he was looking for a more cost-effective alternative. It was at that time he learned of a solution that had been used successfully in other parts of the world for more than 30 years: Aquatherm Greenpipe. But it was not only Greenpipe's lower cost that caught Hughes' and the hotel owner's attention....
