Where can i find case studies including the costs of past commercial projects
I'm a civil engineering student studying the financial feasibility of sustainable materials in commercial construction by comparing the costs of materials for projects of a similar nature that don't use sustainable materials against ones that do. So i guess i'm in need of a database that would have that information?  does anyone know where I could find something like this?
