c. Any mobile home. <br />d. Any buildings or portion thereof subject to standards established <br />by the United States. <br />e. Any state building that must conform to the more stringent <br />"Florida Energy Conservation in Buildings Act of 1974" and <br />amendments thereto. <br />(e) Add the following definition to Section 201.1 on page 2-4 of the <br />energy code: <br />Heated slab. A floor, usually constructed of concrete, that has <br />heat energy supplied into the slab to provide heating to an interior <br />space. <br />(f) Add the following sentence at page 5-2 of the energy code immedi- <br />ately following the last sentence of paragraph 502.2(a)(1): <br />Equation I -A may be used. <br />(g) Add the following paragraphs at page 5-2 of the energy code, <br />following paragraph 502.2(a)3: <br />502.2(b). Insulating/Solar Glass Equivalence: <br />Table 5-2C in Section 502.3(c) shows shading coefficients for solar <br />glass which are equivalent to insulating glass. This table is <br />applicable for residential buildings. <br />502.3(c). Insulating/Solar Glass Equivalence: <br />Table 5-2C indicates the maximum shading coefficients for single -pane <br />solar glass which are equivalent to dual -pane insulating glass with a U <br />value of 0.65 or larger. <br />(h) Replace Table 5-1 at page 5-3 of the energy code with the following <br />Table and new Footnote 1 and amended Footnote 2: <br />Table 5-1 <br />Type Al and A2 Residential Buildings <br />Element Mode Value <br />Walls Heating or Cooling Uo 0.30 Max.1 <br />Roof/ceiling Heating or Cooling Uo 0.05 Max. <br />Floors over <br />unheated spaces Heating or Cooling Uo 0.30 Max. <br />Heated slab <br />on grade Heating R 3.4 Min. <br />1For A2 buildings Uo + 0.38 Max. is permitted. <br />2Roof/ceiling assemblies in which the finished interior surface is <br />the underside of the roof deck, a maximum value Uois 0.09 Btu/h ft.2 F. <br />(i) Add the following Equation 1-A on a new page of the energy code <br />numbered 5-6.1: <br />Equation 1-A <br />Uo + M x UwAw + Ug Ag + U d A d <br />Where: <br />Uo = The average or combined thermal transmittance of the gross <br />exterior wall area. <br />A = The gross exterior wall area. <br />-2- <br />
