TreeHugger shares the best (and most likely only) double entendre-filled — and probably NSFW — passive house PSA out there. Heat recovery systems, naughty lingerie, and adult playthings abound!

EcoBuildingPulse checks out the Greens at Irvington Mews, a $16 million dollar development in Baltimore for low-income seniors. Built to LEED Silver and Energy Star requirements, the energy-efficient complex features low-flow fixtures, low-VOC paints, and ample communal living spaces. 

Co.Design is digging an eco-friendly lamp that's, gasp, actually beautiful. Explains Mark Wilson: "The word 'bohemian' comes to mind. The Drawstring Lamp is full of understated cool, a casual conveyance of 'oh, I just artfully sewed together this clever shade before you came over!' In reality, it’s a very smart take on a truly friendly eco-friendly lamp. It’s a collaboration that began when Design Stories asked artisan recyclers at Returhuset for some extra fabric.

Architizer is super-jazzed for the premiere of "Treehouse Masters," a new Animal Planet series about, obviously, "treehouses and the people who love them." The show, which features the handiwork of arboreal architect Pete Nelson, premieres on Fri. May 31 at 10 pm.

The Wall Street Journal is a touch late to the net-zero party with a real estate trend piece on the rising (mainstream) popularity of homes that produce just as much energy as they consume (or more). David Johnston, the Colorado-based co-author of "Toward a Zero Energy Home," provides a choice quote: "The green building market has evolved beyond the crunchy-granola, Boulder types. We have mainstream builders doing this." 

The New York Times takes a break from exploring Williamsburg to partake in some DIY bathroom tiling.

The Atlantic Cities ponders one of the life's greatest mysteries: "How Do you Get Conservatives to Buy Energy Efficient Products," when, according to findings from a recent study from "Proceedings of the National Academy of Sciences," they want nothing to do with them? Paging Michele Bachmann, paging Michele Bachmann.

Relatedly, Co.Exist tries out BulbTrip, a new website that "aims to take some of the mystery out of LEDs, providing nine metrics to assess which bulb is for you. Look up prices, brightness, and efficiency, and find out what return on investment you’ll get compared to a conventional light. You even get 'perceived watts' ratings (sort of like a weather forecast that gives feels like' numbers as well as actual temperatures)."
