Founded in 1859, Iowa State University (ISU) is an international university located in Ames, Iowa. The campus hosts an enrollment of 36,000 students and 6,000 faculty/staff. The University has a renowned reputation for Science, Technology, Architecture and Engineering.
The campus includes over 100 facilities of higher education. In 1998, ISU Facilities Planning and Management began a process of evaluating best practice to improve the continual cycle of “end-of-life” roof replacements. After research and pilot projects, pressure equalization technology became a reliable process for re-roofing. To date, nearly 1,400,000 SQ feet encompassing 70 projects have been completed on campus with pressure equalization technology.
A key strategy is the inclusion of moisture mitigation capabilities which allows ISU to recover and recycle up to 100% of existing insulation materials. Such roofs are more cost effective, highly weather resistance while minimizing waste streams. Current strategies include the use of 100% upcycled cover boards as part of the ISU long-term sustainability efforts.
New roof assemblies are designed and installed to achieve:
