A report was published in September, 2008 by Yudelson Associates in Tucson, AZ for “The Mechanical Contracting Education and Research Foundation” (MCERF). The report discusses the European and North American markets as it relates to high performance buildings. The differences in climate, culture, politics and economics between North America and Europe are discussed. The report also discusses green building technologies currently in use in Europe with an emphasis on daylighting, green roofs, double facades and “radiant” systems (radiant ceilings, passive and active chilled beams). Dadanco received mention as a supplier of active chilled beams on page 27 of the report and Dadanco's project at 250 South Wacker in Chicago, IL also received mention on pages 31 and 44.
