The course will be taught in both SI and English units.
1. All exams are open book. Closed notes, closed homework.
2. There will be two exams and a final. There will be 5 unannounced quizzes. Quiz questions will closely follow homework problems or parts of homework problems. The worst 2 quiz grades will be discarded.
3. To receive graduate credit graduate students and required to complete an extra project in addition to the course work. Graduate students are expected to submit a written project proposal by February 3 and a completed project 2 weeks before the final. Possible projects could be detailed consideration of an item of air conditioning process equipment; simulation of an air-conditioned structure, detailed design of an air condition system analysis of unique air conditioning systems or a topic of special interest.
4. Course notes will be posted on the course web site on Friday.
5. Homework is due on Monday in class or my office by 1:00 pm. Homework will not be accepted after this time. Homework will be graded and solutions will be posted on the class web site after the homework is due.

There is nothing more dishonorable for an engineer, short of his work causing loss of life or property, than to present the work of another as his own. This can happen in patent applications, reports, presentations, and technical papers. Dishonesty in course work is the start of this slippery slope that ends in news stories such as we have seen reported last year or worse. Pressure may be felt in school however it is more difficult, not easier, to maintain integrity in practice.
Presenting course or project work of another as your own will result in a reduction in grade usually to F.
