CBRE is looking for good ideas to improve sustainable practices for commercial buildings. The global commercial real estate services company has launched a Real Green Research Challenge, which will award as much as $1 million over the next four years for independent academic research in areas such as productivity studies proving the benefits of sustainable building occupancy and best practices or systems software to reduce operating costs or enhance revenue through recycling. As many as 15 qualifying submissions will receive initial funding of up to $15,000 in February 2013, and be eligible for additional funding of up to $250,000. Winners will collaborate with CBRE.

Abstracts of research proposals are due by December 31 at cbre.com/rgrc.
