We are reaching to you, facility managers from around the world, to get a truly international perspective on sustainable facility rating systems as we update the IFMA Foundation's "Sustainability How-to Guide: Green Building Rating Systems." Your input will enable us to detail how the systems differ, cost variances, information about how certifications have been obtained and operational costs have been reduced.

The information requested should be focused on real experiences with green building rating systems and obtaining certifications. Through this survey we hope to answer many of the questions that facility managers have voiced to us and incorporate them in this publication. The guide will also provide case studies that will highlight selected green rating systems.

If you wish to have one of your facilities featured as a case study in this guide, please contact: Marina.Kriticos@IFMA.org.

The authors and the IFMA Foundation thank you in advance for your time and participation in this exciting initiative.
