ARLINGTON, Va. - The Air Conditioning Contractors of America (ACCA) has added a new course for commercial contractors to its fall schedule. The first "Fundamentals of Commercial Load Calculation and Systems Design" class, from ACCA's Contractor Training Series, will take place Oct. 11-13, 2004, in Detroit.

According to ACCA, the course teaches practical procedures for calculating the various components of a commercial facility's heating and cooling load, using ACCA's Manual N. While emphasis is placed on identifying and calculating peak load conditions, discussion is also directed at understanding the structure's needs under part-load conditions.

During the three-day course, contractors will first study Manual N commercial load calculation fundamentals and then learn Wrightsoft's Right-N computerized commercial load calculation program.

The class provides continuing education units plus 20 hours toward North American Technician Excellence (NATE) recertification.

Tuition for the course costs $450 for ACCA members and $495 for nonmembers, which includes Manual N and demo software.
