San Francisco's most venerable spinoff, Chronicle Books, turned 40 this year. The publishing house celebrated by moving into a solar-powered and dramatically renovated space near PacBell Park. We recently went on a tour of the spanking new digs with editor Jodi Warshaw (Midwife to AT's forthcoming house tour book), and here's what we saw: Molo's cardboard seating in the lobby (seen at ICFF but never in real life) and ogled the solar panel-topped roof from below. That's right: the creativity of this brain trust of 180 editors, designers, production and administrative staffers is harnessed using solar energy. To date, half the planned-for panels have been installed and the building is not only producing its own power, but it's downloading extra power into the City's grid. During daylight hours when the lights and ventilation system are off, power is channeled back into the grid and a beautiful thing happens: the Chronicle's power meter runs backwards. The project was led by architect Paul Loeffler of Mark Cavagnero Associates and by Chronicle Books's Creative Director, Michael Carabetta. And it is tended by facilities manager Isaac Sherrer, who graciously answered our questions for this post.
