Everyone knows it's not easy being green, but if you want to get greener and don't know where to start, this here handy lil' guide could be a nice option for ya. IDSA's just published the Okala (hopi for "life sustaining energy") Design Guide for 2007--it's an "introduction to ecological and sustainable design for practicing and beginning designers...It envisions a future where we recognize the value of global ecology and work to insure its protection." This year's revised version, supported by Eastman Chemical Corporation, Whirlpool Corporation and the IDSA/EPA Partnership, serves to emphasize usability to designers and design students.
The Okala promo site gives you a sneak peek at a few sections, but if you want the whole shebang, you'll have to cough up $19 for a copy. If it's a crew, and not just you, discounts are granted for larger orders, and apparently, over 60 D-schools in North America have already requested copies.
