Our Services

Tampa Bay’s solution for buildings and construction calculation documents, consulting and diagnostics.

Manual J Heat Load Calculation

Manual J Residential Load Calculation

Manual J 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 procedure, is required by national building codes and most state and local jurisdictions.

Manual S equipment selection

Manual S Residential Equipment Selection

Manual S is used to select and size heating and cooling equipment to meet loads for a particular home, which are based on local climate and home construction specifics. Contractors in Miami, Phoenix, and Seattle - all extremely different climates - would never use the same equipment and expect the same results.

Manual D duct design basic

Manual D Residential Duct Systems

Manual D provides a single set of ANSI-recognized duct sizing principles and calculations that apply to all duct materials.

Commercial Load Calculation

Manual N Commercial Load Calculation

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 is the commercial version of the Manual J.

Residential Zoning

Manual Zr Residential Zoning

Manual Zr defines the requirements for designing zoned comfort systems for residential buildings, including single family detached and multifamily attached structures. Multifamily attached structures include duplexes, triplexes, town houses, row houses and small to medium size condominiums of three stories or less. Manual Zr also covers large multifamily, multi-floor buildings with dwellings that have their own comfort system, exhaust system, and outdoor air system.

Florida Building Code

Florida Building Code

The Florida Energy Conservation code regulates the design and construction of buildings for the effective use and conservation of energy over the useful life of each building. It is intended to provide flexibility to permit the use of innovative approaches and techniques to achieve this objective. It is not intended to abridge safety, health or environmental requirements contained in other applicable codes or ordinances.
