It has been over 40 years since Ian McHarg first published his seminal publication on the effectiveness of using overlay maps to evaluate of the social and environmental costs of land use change. Yet, the influence of Design With Nature seems to be as evident now as ever.
The next iteration of LEED, scheduled to launch late next year, will introduce a completely reorganized system of identifying RPCs for projects seeking LEED certification.
In the current system, RPCs for each version of LEED are cataloged by zip code. For LEED 2012, RPCs will be organized using an advanced GIS overlay mapping system called RegGIS.
USGBC is currently developing LEED 2012 and as part of the process all 79 Chapters are being asked to develop task forces to examine and reevaluate the LEED Regional Priority Credits (RPCs) introduced with LEED 2009.
RegGIS taps into an impressive collection of databases to offer graphic identifications of issues ranging from combined sewer overflow areas to wind power resources to brownfield density to obesity rates. Chapter Task Forces will leverage this information to identify priority zones within each Chapter boundary. Then, each priority zone will be assigned appropriate RPCs from each version of LEED.
This refined process of identifying RPCs is intended to give LEED an unprecedented level or regional responsiveness.
