Right-Suite Residential J8™ (RSR J8) is based on the Air Conditioning Con-tractors of America’s (ACCA’s) newly released Manual J Eighth Edition. Two levels are being released: the Basic Edition™ and the Professional Edition™. The Basic Edition is intended as an easy way for students to do the simple cases in the manual. The Professional Edition is what all of the company’s customers now have. RSR J8 includes improvements in zoning calculations, glazing materials (allows NFRC factors), radiant barriers, below-grade insulation, duct losses, and more.
