Schedule types for Compact HVAC Autosizing (Compact and Typical workday Schedules)

7/12 Schedules can be categorised using the following categories when using the End-use defaults option:

General - include general purpose schedules in Compact HVAC heating autosizing calculations - on by default.
Occupancy - include occupancy schedules - off by default
Lighting - include lighting schedules - off by default.
Equipment - include equipment schedules - off by default.
Heating demand - include heating demand schedules - on by default.
Cooling demand - include cooling demand schedules - on by default.
HVAC - HVAC schedules - on by default.
Natural ventilation demand - natural ventilation schedules - off by default.
DHW - DHW schedules - on by default.

For example, occupancy gains should normally be excluded when sizing heating plant to ensure that the design heating plant meets all heating loads itself. So leave the Occupancy check box unchecked. Heating and cooling demand schedules must be included to ensure the system operates so the Heating demand and Cooling demand options should normally left selected.

These options are also used for Typical workday schedules.
