If you look at the winter design day input:

SizingPeriod:DesignDay,
    CHICAGO_IL_USA Heating 99.6% Conditions,  !- Name
    -21.20000,               !- Maximum Dry-Bulb Temperature {C}
    0.0,                     !- Daily Temperature Range {deltaC}
    -21.20000,               !- Humidity Indicating Conditions at 
Maximum Dry-Bulb
    99063.21,                !- Barometric Pressure {Pa}
    4.600000,                !- Wind Speed {m/s}
    270.0000,                !- Wind Direction {deg}
    0.0,                     !- Sky Clearness
    0,                       !- Rain Indicator
    0,                       !- Snow Indicator
    21,                      !- Day of Month
    1,                       !- Month
    WinterDesignDay,         !- Day Type
    0,                       !- Daylight Saving Time Indicator
    WetBulb;                 !- Humidity Indicating Type

You'll notice that Sky Clearness is zero; this turns off all solar 
radiation.
> 2) Getting Started Guide: In Step 2 part 2. paragraph on pg 34 gives a figure of 7650 cfm for zones 1 and 2 total. Table 2 pg 33 zones 1 & 2 sum to 6400 cfm. Typo??
