Manual J 8th Edition is the national ANSI recognized standard for producing HVAC equipment sizing loads for single-family detached homes, small multi-unit structures, condominiums, town houses, and manufactured homes. A proper load calculation, performed in accordance with the Manual J 8th Edition procedure, is required by national building codes and most state and local jurisdictions.

The New Fifth Edition of Manual N® details the load calculation procedure that addresses the advances in the commercial construction industry: new materials, methods of assembly, and operational requirements. It provides instruction to help contractors and designers satisfy new, and often conflicting, energy, ventilation, and comfort requirements. The new Manual N is divided into four sections providing both a quick and comprehensive procedure for commercial load calculation.

• Section 1 Abridged Procedure: Basic instructions to perform commercial load calculations, on buildings of three stories or less. Supports a simplified hand calculation.
• Section 2 Advanced Topics: Provides enhanced procedures, capabilities, and sensitivities (requires computer software to process).
• Section 3 Tables: Provides input for the worksheets and determinations needed for the abridged (N5ae) and full (N5) procedures.
• Section 4 Appendices: Provides supporting materials and details on the N5ae and N5 applications...(640 pages)
