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.

In 1985, Rocky Mountain Institute co-founder Amory Lovins coined the term “negawatt” to describe the value of electricity not used, either through improved energy efficiency or reduced consumption. At the time, he was considered a bit of a fringe thinker.

A new Department of Energy (DOE) initiative is paving the way to ensure that more and more K–12 schools built in the United States are zero energy.

The second annual Energy Efficiency Day will take place October 5. This year's theme is, "Save energy. Save money."

Cost competitiveness has long been solar power’s biggest challenge. The industry has made great progress on this front and now may be looking beyond cost to other challenges that impede widespread adoption.
