It’s a myth that reducing electric energy consumption by installing energy-efficient lighting will have a significant impact on oil consumption. According to the Energy Information Administration, oil accounted for only 1.6% of electric power generation in the United States in 2007. Coal is the largest producer of electric power in the U.S. at 48.5% of [...]

Lighting Our Near Energy Future
Studies show that commercial buildings produce about half of greenhouse gas emissions contributing to climate change—making these buildings the top emitter of human-caused greenhouse gases, ahead of cars and trucks—while consuming nearly three-fourths of electricity produced at power plants. The Commercial Buildings Initiative (CBI) is a public-private partnership formed to achieve an ambitious goal: By [...]

Are LEDs Ready to Retrofit the T8?
A recent article I wrote for Electrical Contractor talks about the push to replace linear fluorescent lamps with linear LED replacement lamps. In a nutshell, linear LED replacement lamps are now being offered as direct drop-in replacements of 4-ft. T8 and T12 lamps. Even with the possibility of delamping due to higher fixture efficiency and [...]

USGBC Reaffirms Commitment to Developing Green Building Code
The U.S. Green Building Council recently reaffirmed its commitment to the development of Standard 189.1P, which will be America’s first National Standard developed to be used as a green building code when completed. Created specifically for adoption by states, localities, and other building code jurisdictions that are ready to require a minimum level of green [...]

Study Captures Daylighting’s HVAC and Lighting Energy Savings Impacts
Daylighting is recognized as best practice in energy codes and industry standards due to its documented positive effects on worker satisfaction and performance and potential to generate substantial energy savings. Daylighting and daylighting control are now encouraged or required by California’s Title 24 energy code, LEED-NC v.2.2, Northeast Collaborative for High Performance Schools, and ASHRAE [...]
