ACCA-certified load calculations and system design for residential and commercial buildings. Documentation compliant with Florida Energy Code and applicable state codes.
RASTEC Engineering provides ACCA-certified HVAC load calculations and design documentation for residential and commercial projects. Services are coordinated with structural and permitting requirements under RASTEC's full EOR engagement model, or delivered as standalone HVAC engineering packages.
RASTEC is certified in ACCA Manual J, S, and D for residential systems and Manual N for commercial occupancies. Calculations are produced using Wrightsoft and EnergyGauge USA, the tools accepted by Florida's Energy Code compliance reviewers.
RASTEC follows ACCA (Air Conditioning Contractors of America) manuals as the standard for HVAC sizing, selection, and distribution design.
Defines procedures for calculating heating and cooling loads in residential buildings based on building geometry, insulation, window properties, orientation, internal gains, and local climate data.
Provides guidance for selecting HVAC equipment based on Manual J results. Matches equipment capacity and performance to actual load conditions and part-load efficiency requirements.
Covers duct layout and sizing to deliver required airflow with acceptable friction losses and air velocities. Addresses trunk-and-branch and radial systems, fitting losses, and material specifications.
Addresses load calculations and design considerations for commercial buildings. Includes guidance for zoning, ventilation, internal loads, and integration with commercial modeling tools including Wrightsoft Right-N.
