During his tenure at APS, Mark directed the development of a world-class technology transfer project, the APS Environmental Showcase Home (ESH).  This sustainable construction project consumes 85% less energy and 60% less water than a typical home, while showcasing over 150 sustainable technologies, strategies and materials.  This project could arguably have achieved the U.S. Green Building Council’s LEED® Platinum rating if the standards were in existence when the Home was built in 1995.  The ESH reached over ten million Americans through free media and had transformational impact on the local building community. Over 40,000 people toured the Home since its completion in 1995.  The Home received over 26 major environmental awards, including an international award in 1997 as the top environmental project in all of North America.  The ESH was the subject of an eight-part PBS television series titled This New House, and a book titled The Environment Comes Home, for which Mr. Wilhelm was a contributing author.
