	Subject - Commercial / Industrial relbas Can you clarify the difference between commercial and industrial JimmyDee Commercial usually relates to a retail store type of building, office building or banking type building. Industrial is usually classified as a manufacturing building, paper mill, chemical plant, refinery, and other buildings that are used to produce a product rather than selling it. Jim Russell120 The gray area to me is between commercial and institutional. Institutional is government, universities, schools, hospitals, prisons. To me institutional seems best described as large buildings built to last. Some of the large commercial projects can look a lot like institutional jobs. Some of the factories I have worked on also seem more like commercial work because they will have a lot of offices and a cafeteria, but the working floor won't have any of the heavy electrical equipment you associate with manufacturing. And what a bio-tech greenhouse is supposed to be classified as is beyond me. I guess there is so many types of buildings no system is going to be perfect.
