Its point-based Leadership in Energy and Environmental Design (LEED) certification is the most widely used building rating system in the world, with tiers ranging from Certified (40-49 points earned) to Platinum (80+ points earned). In addition to environmental benefits, green buildings are also more attractive to investors and tenants alike, yielding higher occupancy rates and rental income than traditional buildings. BXP currently has 24.3 million square feet of LEED-certified buildings — about half of its portfolio — and the company has made it a requirement for all new developments to be LEED-certified at the Silver level or higher, outperforming its industry peers.
