DALLAS, TX -- StonExpo/Marmomacc Americas 2009 has announced a new class on sustainability in the natural stone industry, presented by Jack Geibig, P.E., of the Center for Clean Products. "Assessing the Sustainability of Stone as a Green Building Material" will be offered on Friday, October 23, from 8:00 to 9:30am as part of the Building/Design track, which is sponsored byArchitectMagazine.

"The issue of sustainability in our industry is one that demands our full attention," states Duke Pointer, Executive Director of the Natural Stone Council, an Official Sponsor of StonExpo/Marmomacc Americas. "As our profession continues to progress, we need to ensure that the projects we design and build today will have minimal impact on the environment both now and in the future. Jack's course is one that should not be missed."

The session will focus on the use of stone materials in building, the definition of environmental profiles for stone materials as used in green building as well as discuss profiles of materials that are replacements for stone (pre-cast concrete, aluminum, etc.). A comparison of common materials used for external cladding, along with the results of a recently completed cladding life-cycle assessment, will also be examined.

"Including a course of this nature in our conference program reinforces our commitment to the natural stone industry and the topics that matter most to them," states Dana Teague, Show Director for StonExpo/Marmomacc Americas. "The subjects that Jack is presenting are some of the most important factors that our attendees must consider as they bid for and complete jobs."

The Marble Institute of America, also an official sponsor of the show, feels that Geibig's presentation will benefit all attendees. "The issue of how natural stone fits into the 'green movement' should be of interest to every firm in the industry. Green building is the present and future of construction. The Marble Institute is, and has been, involved in and very supportive of the NSC-funded work of Jack Geibig and his team at the University of Tennessee," states Gary Distelhorst, CAE, Executive Vice President and CEO of the MIA. "Their work to research the environmental footprint of stone is of vital importance towards helping the industry position itself as a preferred and desirable option for green building projects. The results of the research will allow us to compare stone to other building materials in an apples-to-apples environment."
