This is a course on the Manual J (7th Edition) for accurate procedures which can be used to estimate the heat loss and heat gain for conventional residential structures. The sections and Tables 1 through 9 form a module that is specifically intended to provide step-by-step instructions on how to perform the Manual J calculations.  If your state exam focuses heavily on load calculations using the Manual J (7th Edition), this 2-hour course could be a tremendous help in achieving a passing score. All of our online seminars are professionally narrated and animated with graphic illustrations of the concepts being taught, and our web-based presentation system tracks your progress so you can work through the materials at your convenience, resuming where you left off with each login.
