Pre-fab enviro-friendly homes

Didn’t know such things existed until I stumbled across the Forbes article “Stunning Solar Powered Homes.” As it turns out there’s a company called LivingHomes (livinghomes.net) that designs, manufactures and assembles eco friendly homes that are LEED certified out of the box.
They also use some components that existing homes could benefit from, such as PermaLight‘s LED based lighting products.
