Basic Sustainable Lighting Concepts: On Electric Lighting
Part 3 of an ongoing series outlining design principles for sustainable lighting design: here are a few ideas regarding electric lighting to help navigate the greenwash. Strike a balance between efficiency and functionality The efficiency of a light fixture or system is not a replacement for functionality and aesthetics. On the other hand, the... »
The 50% Rule
What is the 50% rule? Well, I just made it up – just now. It’s not a new concept by any means; I’m applying it to lighting, although I suppose you could apply it to just about anything. It’s about efficiency and utility: how much of something do you get versus how much you... »
The Lure of the Time-Based Energy Code
Energy codes got you down? Is squeezing wattage cramping your design? You’re not alone – a lot of designers feel this way, and for good reason. As the country demands more and more energy efficiency, we’re spending more and more time counting watts and squeezing every last drop from power allowances just to make... »
Solar Decathlon: Not So Sunny, But Full of Energy!
I was fortunate to be able to spend the weekend visiting the Solar Decathlon houses on the Mall in Washington, D.C. (see the Solar Decathlon website and Amber’s last blog article “Curious” About Sustainable Design?). Miserable weather meant that the houses weren’t generating much electricity, but the energy produced by the students attracted many... »
Quality Trumps Efficiency in the Lighting Game
Today, after decades of conspicuous energy and material consumption, escalating energy and construction costs and the desire to be more environmentally sustainable are forcing designers to rethink their strategies and to ask how we can do more with less. More stringent energy codes and LEED energy targets are among the most challenging of all... »
What’s “Efficient”?
Today we’re barraged by claims of “efficient lighting” or criticisms of “inefficient lighting”, but what does that actually mean, or what should we actually be concerned about as designers? In casual terms, we think of “efficient” lighting as using less energy to produce a given amount of light, or as producing more light for... »
