For modular construction in Florida, the Florida Building Code regulates the quality, health, and safety of home construction by defining the types of materials and methods that are to be used in all aspects of construction. In addition to the Florida Building Code, modular homes must comply with the Florida Building Code (2017) Energy Conservation for homes which defines the requirements for the thermal performance of the building envelope (including walls, ceilings, roofs, windows, doors, and insulation); of heating, cooling, and ventilation (HVAC) system; and of electrical components such as the lighting system. The following sections provide information about some of the key requirements of the Florida Building Code (2017) Energy Conservation for homes.
