�Zd <br />- <br />Climate Zone 1 <br />AW I --%, .n. <br />Instructions; <br />A. The following slops will determine the mazlmum heating system size <br />1. 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 (Ft3) of the conditioned spare in the dwelling. <br />3, Climate Factor, QT: 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 o by multiplying the numbers In each horizontal row. <br />6. Add values a. b, and c, <br />7. Multiply Ilia sum from Step #6 by 1,5 to obtain the maximum heating system output for the buliding. <br />8. V file heating system is electric, divide the BTU/hr. value from Stop 47 by 0413 to got Watt output. <br />Heat loss path <br />Values LT i <br />ACH ° <br />Factors <br />, ; az xs) BTU/Hr. <br />; _;;: <br />Structural loss <br />(1) <br />(BTU/HO/ <br />X <br />_ <br />(a) <br />Air leakage loss <br />(2) <br />(1T3) <br />X <br />x .35 <br />X 0.018 <br />(b) <br />Duct losses <br />(3) <br />(BTU/Hr) <br />x .10 <br />= <br />(c) <br />Permit No. <br />Name lctrY—roc 0'10 <br />Street f� �2,v Q+, �F <br />Lot# <br />City 'e' <br />County Sno,v„-GL.L% <br />Phone# 2O(� :i.S :1-6.gC0 <br />Design Heat Load <br />(a+b+c) <br />Maximum Heating Output <br />(Gas, oil, propane, wood) <br />(Design Heat Load X 1.5) <br />Type of system Maximum Heating Output <br />Model # (Electric, heat pumps) <br />Heating output _II V TU/hr.
