A Few Thoughts.
Lighting Designer Pilots Texas-Sized Airport Project: An Interview with Monte Riggs, AIA, IES
Monte Riggs of Bos Lighting Design spent four years designing lighting for Houston’s George Bush Intercontinental Airport which, not long ago, underwent a $112 million renovation. We asked the award-winning architect and lighting designer about the project: Your firm helped re-light terminals A and B. Give us a little history about where things stood when you jumped into Terminal C? The previous projects had no energy code limitations. The light levels were achieved by power densities that far exceed what current codes allow. The client’s desire was for Terminal C to look more like A and B. So we had read more
Can Natural Light Make Employees More Productive?
Would you be more productive working in natural daylight than under those old T12 fluorescents in your office? I am sure the answer is yes. Now what if the ceiling in your office could simulate that experience of sitting outdoors, would you still be more productive? A new LED lighting system from a German high-tech research firm was designed to answer this question. Click here to read the article.
Concrete Light
Light-transmitting concrete from Litracon is a fascinating concept. With 4% optical fiber it probably isn’t cheap, but if it eliminates the need for façade or exterior perimeter lighting, the savings in fixture and energy cost helps justify the building material cost. Intriguing!
Using Blue Light To Our Advantage
A recent New York Times article in the health section explains the idea that exposure to light at night can suppress one’s production of melatonin, a hormone that promotes sleep, and thus disrupts our 24-hour circadian cycle. It also expands on more recent experiments showing that specifically blue light is especially effective at suppressing our release of melatonin, and in fact, keeps us more awake and alert. What does this mean for us in the lighting world? Most LEDs for general lighting use blue LEDs with specific phosphors that change this near-ultraviolet light into white light. At night these blue read more
Photosensor Placement Tips – Save Energy, Save Confusion
The use of photosensors is crucial to saving energy, especially in areas where stringent watts-per-square-foot requirements are in effect. California is one such place and here, under Title 24, credits are given for lighting installations with photosensors allowing lighting specifiers greater flexibility to meet the State’s restrained watts-per-square-foot requirements. As other states move to limit wattage, it is very likely similar sensor credits will soon become the norm in lighting codes across the nation. Therefore, we believe every lighting pro should know how to best use and place photosensors. But placement can be tricky. And there are many factors to read more
