Last month, Lorax Development broke ground on a building that’s being billed as the first off-grid building in San Francisco. At 1400 sf, The Eco Center is certainly an example of the future of green buildings — buildings that are off-grid and sustainable. The Eco Center is a $1.5 million environmental education center that will be located in McLaren Park. Designed by Toby Long Design for the non-profit Literacy for Environmental Justice (LEJ), when it opens in the fall, it will be the first building in San Francisco, purportedly, to recycle its own wastewater. Additionally, the off-grid center will have solar panels and an extensive green roof.
