Some of us LJ folks are in San Francisco today for a daylong conference on green library design--at an LJ Design Institute called "Going Green." It's the second one we've done in six months on green building issues (the last one was in Chicago in December, see full coverage in the forthcoming Spring Library By Design supplement). It's no surprise we're revisiting the topic, given the growing intensity around the need for energy conservation and the importance of making sustainable choices across our lives. As LJ's Editor-in-Chief, Francine Fialkoff, noted in her editorial following  the Chicago institute, when we design library buildings, whether they be brand new or retrofitted beauties, we get a unique opportunity to model these sustainable choices for our communities, educating other community leaders and patrons along the way. We're just gettting started here at San Francisco's main library, but I suspect that message will get reinforced today, but so will the nitty gritty of how, choice by choice, to make it happen.
