Los Angeles is getting a lot greener today. Over in Westwood, the Hotel Palomar is opening, with 268 guestrooms and suites, views of the city's skyline, and more than 40 eco-friendly practices (including in-room recycling bins, energy-efficient lighting, and organic food and beverages in the minibars). Special introductory rates start at $229; see www.hotelpalomar-lawestwood.com for more information. And over on Robertson Boulevard, the latest edition to the H. Lorenzo retail empire is ready to welcome shoppers (on-again BFFs Katie and Posh are fans of the mini-chain) with a solar-powered boutique designed by Oliviero Baldini. The 4,000-square-foot shop, which stocks Zac Posen, Viktor & Rolf, and Veronique Branquinho, is completely paperless—meaning your Balmain purchase will be tucked into a reusable linen shopping bag and you'll get an e-mail receipt.
