Where required by the code official,testing shall be conducted by an approved party. Hourly calculations <br /> as specified in the ASHRAE Handbook of Fundamentals,or the equivalent shall be used to determine the <br /> energy loads resulting from infiltration. <br /> b. The combined air exchange rate for infiltration and mechanical ventilation shall be determined in <br /> accordance with Equation 43 of 2001 ASHRAE Handbook of Fundamentals,page 26.24 and the"Whole- <br /> house Ventilation"provisions of 2001 ASHRAE Handbook offundamentals,page 26.19 for intermittent <br /> mechanical ventilation. <br /> c. Thermal storage element shall mean a component not part of the floors,walls or ceilings that is part of a <br /> passive solar system,and that provides thermal storage such as enclosed water columns,rock beds,or <br /> phase-change containers.A thermal storage element must be in the same room as fenestration that faces <br /> within 15 degrees(0.26 rad)of true south,or must be connected to such a room with pipes or ducts that <br /> allow the element to be actively charged. <br /> d. For a proposed design with multiple heating,cooling or water heating systems using different fuel types, <br /> the applicable standard reference design system capacities and fuel types shall be weighted in accordance <br /> with their respective loads as calculated by accepted engineering practice for each equipment and fuel type <br /> present. <br /> e. For a proposed design without a proposed heating system,a heating system with the prevailing federal <br /> minimum efficiency shall be assumed for both the standard reference design and proposed design. <br /> f. For a proposed design home without a proposed cooling system, an electric air conditioner with the <br /> prevailing federal minimum efficiency shall be assumed for both the standard reference design and the <br /> proposed design. <br /> g. For a proposed design with a nonstorage-type water heater,a 40-gallon storage-type water beater with the <br /> prevailing federal minimum energy factor for the same fuel as the predominant heating fuel type shall be <br /> assumed. For the case of a proposed design without a proposed water heater, a 40-gallon storage-type <br /> water heater with the prevailing federal minimum efficiency for the same fuel as the predominant heating <br /> fuel type shall be assumed for both the proposed design and standard reference design. <br /> h. For residences with conditioned basements,R-2 and R-4 residences and townhouses,the following formula <br /> shall be used to determine glazing area: <br /> 24 <br />
