During the years of planning Shillim, “green,” “sustainable” design started to gain currency. LEED and other environmental guideline systems began to guide architecture and landscape design around the world. Between 1997 and 2012, the practices pioneered at Shillim early on — reforestation, sustainable storm-water management, grey water recycling, minimum-impact standards, for example – shifted from fringe to mainstream. Today the place uses almost 500 KW capacity of solar energy to run its administrative buildings.
