By planning ahead you can LEED Certify your home or office for little or no additional expense. At Lohre & Associates, we self documented our own offices to the LEED Platinum level for only $12 per square foot for the complete office makeover including application fees. LEED stands for Leadership in Energy and Environmental Design by the U.S. Green Building Council (USGCB), a non-governmental, non-profit agency founded in 1993. LEED has become the most widely accepted Green Building standard.
