Structural loss, value (1): May be taken directly from the Proposed UA box on page 2. <br />2.. Air leakage loss, Value (2): This Is the volume (Fl3) of the conditioned space in the dwelling. <br />3. Climate Factor,,LT: The local ASHRAE climate factor is—F, for your Jurisdiction (call WEES if unsure). <br />4. Duct Loss, value (3): Insert value from BTU/Hr, Box (a). <br />5, Calculate values a, b, and c by multiplying the numbers In each horizontal row. <br />6. Add values a, b, and c. <br />7. Multiply the sum from Stop #6 by 1.5 to obtain the maximum heating system output for the building. - <br />8. if the heating system Is electric, divide the BTU#rr. value from Step #7 by 3413 to gel Walt output. <br /><•-. <br />Heat loss ath �r ��'� � • Values T <br />ACH <br />Factors �°'I BTU/Hr.
