In this project we determined the minimum first-year cost of an active soil ventilation system. The results indicate the duct diameter and the fan brand that achieve the minimum cost. Some aspects of the problem were controlled in order to maintain a proper scope for the project. Initial results obtained from LINDO agreed with hand calculations. This indicates that appropriate models were constructed, and that these models were properly constrained. The sensitivity analysis indicated that fine variations can affect the basis.


This project is only available to students, staff, and faculty of Portland State University.
