Exceptions: 1. Ad- ditions of 600 square feet (56 m or less may have maximum glass to CFA of 50 percent. 2. Renovations with new windows under. 2 foot overhang whose lower edge does not extend further than 8 feet from the overhang may have tinted glazing or double -pane clear glazing. Replacement skylights installed in renovations shall be double paned or single paned with a diffuser. (3) R- Values are for insulation material only as applied in accordance with manufacturers' installation instructions. For mass walls, the "interior of wall" requirement (R -6) must be met except if at least 50% of the R -4 insulation value required for the "exterior of wall" is installed exterior of, or integral to, the wall. (4) Attic knee walls shall be insulated to same level as ceilings and shall have a positive means of maintaining insulation in place. Such means may include rigid insulation board or air barrier sheet materials adequately fastened to the attic sides of knee wall framing materials. (5) For other electric storage volumes, minimum EF = 0.97 - (0.00132 * volume). (6) For other natural gas storage volumes, minimum EF = 0.67 - (0.0019 * volume). (7) For all conventional units with capacities greater than 30,000 Btu/hc For Small -Duct, High - Velocity units, Space Constrained units, and units with capacities less than 30,000 Btu/hr see Table 13- 607.AB.3.2A of the Florida Building Code, Building, or Table N1107.AB.3.2A of the Florida Building Code, Residential. (8) For all conventional units with capacities greater than 30,000 Btu/hr.

(9) All ducts and air handlers shall be either located in conditioned space or tested by a Class 1 BERS rater to be "substantially" leak free. "Substantially leak free" shall mean distribution system air leakage to outdoors no greater than 3 cfm per 100 square feet of conditioned floor area at a pressure differential of 25 Pascal (0.10 In. tic.) across the x entire air distribution system, including the manufacturer's air handler enclosure. Exception: New or replacement ducts installed onto an existing air distribution system as part of an addition or renovation. Such ducts shall either be insulated to R -6 or be installed in conditioned space. xx 10) The prohibition on electric resistance heat and the requirement for programmable thermostats do not apply to additions, renovations, and new heating systems installed in existing buildings.
