This tool will calculate heating loads only. ACCA procedures for sizing cooling systems should be used to determine cooling loads. <br />Please complete the green drop -downs and boxes that are applicable to your project. As you make selections in the drop -downs for each section, some <br />values will be calculated for you. If you do not see the selection you need in the drop -down options, please contact the WSU Energy Program at <br />energycode@energy.wsu.edu or (360) 956-2042 for assistance. <br />Project Information Contact Information <br />Cyprus DADU 11 Jones <br />Heating System Type: O All Other systems O Heat Pump <br />To see detailed instructions for each section, place your cursor on the word 'Instructions" <br />Design Temperature <br />Instructions. .+..., Design Temperature Difference (AT) <br />Everett JC AT = Indoor (70 degrees) - Outdoor Design Temp <br />II��I <br />Area of Building <br />Conditioned Floor Area <br />Instructions Conditioned Floor Area (sq ft) <br />Average Ceiling Height <br />Conditioned Volume <br />Instructions Average Ceiling Height (ft) <br />6,927 <br />Glazing and Doors <br />U-Factor <br />X Area = <br />UA <br />Instructions <br />u-0.25 <br />0.250 <br />283 <br />70.75 <br />Skylights <br />U-Factor <br />X Area = <br />UA <br />Instructions <br />0.50 <br />— <br />Insulation <br />Attic <br />U-Factor <br />X Area = <br />UA <br />Instructions R-49 — <br />0.026 <br />456 <br />11.86 <br />Single Rafter or Joist Vaulted Ceilings <br />Ill <br />X Area <br />UA <br />Instructions —" <br />R-49 Advanced <br />0.020 <br />401 <br />8.02 <br />Above Grade Walls (see Figure 1) <br />U-Factor <br />X Area <br />UA <br />Instructions R-zi In r pws R-a ci <br />0.043 <br />731 <br />31.43 <br />Floors <br />U-Factor <br />X Area <br />UA <br />Instructions <br />LR38 _ <br />0.025 <br />283 <br />7.08 <br />Below Grade Walls (see Figure 1) <br />U-Factor <br />X Area <br />UA <br />Instructions - <br />No Below Grade Walls in this project. <br />0.028 <br />Slab Below Grade (see Figure 1) <br />F-Factor <br />X Length <br />UA <br />Instructions <br />No Slab Below Grade in this project. <br />0.303 <br />--- <br />--�� <br />Slab on Grade (see Figure 1) <br />F-Factor <br />X Length <br />UA <br />Instructions — <br />No slab on Grade in this project. -' <br />-__. <br />-- <br />Location of Ducts <br />Instructions <br />Conditioned Space <br />Duct <br />Leakage Coefficient <br />1.00 <br />_ <br />Sum of UA <br />129.13 <br />Figure 1. <br />Above Grade <br />47 <br />Envelope Heat Load 6,069 Btu/Hour <br />SumofUAxAT <br />Air Leakage Heat Load 3,516 Btu / Hour <br />Volume x 0.6 x AT x 0.018 <br />Building Design Heat Load 9,586 Btu / Hour <br />Air leakage + envelope heat loss <br />Building and Duct Heat Load 9,586 Btu / Hour <br />Ducts in unconditioned space: sum of building heat loss x 1.10 <br />Ducts in conditioned space: sum of building heat loss x 1 <br />Maximum Heat Equipment Output 13,420 Btu/Hour <br />Building and duct heat loss x 1.40 for forced air furnace <br />Building and duct heat loss x 1.25 for heat pump <br />(07101113) <br />
