Green Building

 

A blooming industry, green building is rising with greater public demand, legislative focus, and code and standard mandates. With programs like Leadership in Energy and Environmental Design (LEED) becoming more popular, contractors are finding new building processes and technologies to be more efficient and environmentally minded. The below articles dive into alternative energies, energy efficiency, the smart grid, and more and include editorial from our annual special issue on the subject.

The modern movement toward more sustainable-energy practices has touched almost every aspect of our daily lives. From renewable power to electric vehicles (EVs), few of these changes have gone unnoticed, and the trend affects almost everyone in one way or another.


Rooftop photovoltaic (PV) panels might not yet be a standard home appliance, but they could be on their way if current growth rates keep up. Even after several record years, installation figures continue to climb.

LEED v4, the latest version of the Leadership in Energy and Environmental Design (LEED) rating system, reflects an ultimate goal by the U.S. Green Building Council (USGBC): make a LEED-certified building forever green. A theme of “trust but verify” emerges as you look at the changes in LEED v4.

The house of tomorrow is now 90 percent here, according to Michael Koenig.
