New Home Construction


Square floor area is defined as all completely finished floor space, including space in basements and attics with finished walls, floors, and ceilings. This does not include a garage, carport, porch, unfinished attic or utility room, or any unfinished area of the basement. This footage usually does not contain unfinished space. However, in townhouses, the gross square footage often includes the whole lower level, even though that area might include a garage and unfinished rooms.

Adding a new structural element is considered new construction.

Residential Construction


Square footage for multifamily buildings is defined as all floor and associated living space. Floor space is defined as the floor area of all completely finished living space in the building, including the basement and attic, with finished walls, floors, and ceilings. This does not include a garage, carport, porch, unfinished attic or utility room, or any unfinished area of the basement. Associated living space is defined as hallways, elevator space, lobbies, and any other indoor space used by the residents.

If the structure is demolished and rebuilt on the existing foundation, it is considered new construction.


In the past, homeowners could sometimes replace part of their system, such as the outdoor condensing unit, to extend its useful life. However, air-conditioning and heat-pump systems manufactured today, by law, must have a seasonal energy efficiency ratio (SEER) of 13 or higher. For these new, high-efficiency systems to work properly and to extend their life, the outdoor unit and indoor unit must be perfectly matched. So if you install a new high efficiency outdoor unit, but don’t install a new, equally efficient and properly matched indoor unit, the results could be uncomfortable, frustrating, and expensive. Because newer equipment usually is more energy efficient than older, central air-conditioning or heat-pump systems, you will likely see reduced utility bills.


Construction in a building which may change the structural parts, mechanical equipment, or location of openings, but does not increase the overall area of dimensions of the building.


Any alterations to the interior is considered as remodeling as long as there is not a resulting increase in area.

Home Additions

Any additional area added to the original building is considered new construction. An expansion to an existing structure, generally in the form of a room, floor, or wing, which will increase the floor area or volume of a structure.

Energy Calculations

In the state of Florida all new construction projects must submit a completed Form 405-2017 along with the signed & sealed drawings to the permit office. This meets the requirements of Florida Building Code: Energy Conservation.

Does your project require an Energy Calc?
Projects that do not have air-conditioning or heating are exempt from being required to submit energy calculations. The project must not have provisions for future (or the potential) air conditioning.

Any area that is considered a Living Area and will be Conditioned will require an Energy Calculation.

If area was previously Unconditioned and now being brought up to Conditioned Living Area, an Energy Calculation is required.

The Code provides for a uniform standard of energy efficiency by setting minimum requirements for exterior envelopes, lighting, electrical distribution, and selection of heating, lighting, ventilating, air conditioning and service water heating systems.

Manual J

Project Title

Manual J is a heat loss/gain calculation. This calculation is the staging point for all aspects of the heating and air conditioning system which will follow. This calculation will determine the air flow requirements for each room, supply register, and return grille.

There are two types of Manual J load calculations:

Whole House (Block) HVAC Load Calculations
Whole House or Block HVAC Load Calculations provide the heating and cooling loads for the entire home. This type of load calculation is used when there is no need to design or modify an existing duct system. Whole house load calculations are commonly used to determine the correct HVAC equipment size and match-up that is required when replacing the HVAC system in an existing home.

Room-by-Room Load Calculations
Room-by-Room Load Calculations provide the heating and cooling loads for each individual room within the home. In addition to the information produced by a block load calculation, the Room-by-Room method also determines the amount of air that is required to heat and cool each individual room. This information is critical when determining the individual duct sizes as well as the size and overall layout of the duct system.

Duct Design

Project Title

To design a Duct System, the HVAC system designer must have completed a Room-by-Room Manual J load calculation as well as a Manual S equipment selection.

All to often, duct systems are created using rule-of-thumb methods in lieu of using Manual J, Manual S and Manual D.

This practice is the predominant reason for complaints of temperature differentials throughout a home as well as complaints of excessive noise caused by air velocity that exceeds the maximum allowed by Manual D.

Manual S

Project Title

The capacity of an air conditioner is a moving target. It depends on three environmental variables: outdoor temperature, indoor temperature, and indoor humidity, and one system variable: airflow at the evaporator coil. Further complicating matters, an air conditioner's total capacity is split between sensible capacity (satisfies the thermostat) and latent capacity (removes moisture from the air).

As it turns out, the sensible-total ratio, also known as sensible heat ratio (SHR), is also a moving target. It's important to note that the SHR is not a design condition but rather a result of the design conditions. Change any one condition, and you change an air conditioner's sensible and latent capacity.

Speedy Calc's LLC determines from the calculation, the best equipment to meet the system's, or home's, requirements. Here we follow ACCA's Manual S: Residential Equipment Selection guide. This determines the specific blower performance, which then becomes critical in the duct design / sizing process.

Manual S picks up where Manual J leaves off. It lays out a fairly simple procedure for selecting equipment based on the design loads. You need to know the system's sensible and latent capacity at the design conditions specific to the project. This information can be found only in the manufacturer's expanded performance tables.

These tables are at the core of the Manual S procedure for air conditioners and heat pumps.

Project Title

Manual D

Project Title

A rough sketch of the home's preferred air distribution system is drawn showing equipment placement, register and return locations, air flow requirements for each room, each supply register and return grille, and the location and lengths of ductwork to tie it all together. More than 1 sketch may be necessary to determine the best duct layout based on the architectural layout and structural members of the home.

Now ductwork sizing begins. ACCA's Manual D procedures size the ductwork accounting for blower performance, room-by-room cfm needs for both cooling and heating, distance of ducting to each register or return, all ductwork fittings in the system, type of ducting material planned (sheet metal, flex, or duct board), and any other restrictions in the duct system.
