    Once the individual space loads, psychrometrics, and equipment loads are all calculated, the engine determines the final block loads of the zones, levels, and building. These values are simple block loads that sum the component breakdowns at the hour and month of the maximum load value. The zone and building summary also includes the equipment from their respective sources. The values of the various peak loads are dependent on whether the equipment used is constant or variable air volume. They break down as such:

      Constant Air VolumeVariable Air Volume
    BuildingPeak of space sums in building + sum of zone equipment Peak of space sums in building + sum of zone equipment
    LevelPeak of space sums on level (no equipment) Peak of space sums on level (no equipment)
    ZonePeak of space sums in zone + equipment Peak of space sums in zone + equipment
    SpaceLoad at zone's max month/hour Load at space's max month/hour

    At the end of the process, the engine has populated component breakdown arrays ranging over each hour and month combination for each space, as well as a maximum value of each of these components for every level, every zone and the building. It is a large amount of data, but it gives the consuming application (Revit) the ability to show many different patterns, trends, and data to the user.
