Pro#osal re6uirements

• Descri#tion of all the alternatives considered.

• Descri#tion of the #ro#osed redesi!n and the eistin! systems it re#laces or modifies

• Justification of #ro#osed "or3 includin!, as a##lica$le, im#act on ener!y consum#tion,

comfort, air 6uality, o#eratin! cost, construction cost, maintaina$ility, etc. Educationalvalue is a valid (ustificationN

*onsultants

For AE %&), students have $een assi!ned to a Mechanical Systems faculty advisor "ho "ill!rade all assi!nments, and for "hom you "ill com#lete an AE %G> SE at the end of thesemester. ou are free to consult "ith any of the faculty as you develo# your #ro#osal for theS#rin! Semester 7AE %&'8. ou "ill $e assi!ned a #rimary advisor for AE %&' $ased onrevie" of #ro#osal to#ics.

our advisor may esta$lish a mandatory #ro!ress meetin! schedule, and you are encoura!ed toschedule other a##ointments as necessary throu!hout the semester.

Miscellaneous "ords of "isdom

• he most common cause of a #oor AE %&' #ro(ect is #rocrastination therefore itOs

to your advanta!e to stay on or ahead of schedule.

• 9n order to stay on schedule you may need to "or3 on some assi!nments

concurrently. ee# in mind that time la!s are $uilt into the #rocess of o$tainin!information needed for your eistin! conditions evaluation and #ro#osal, so #lanaccordin!ly.
