Gains data model Option

There are three levels of gains model detail:

Lumped - all internal gains including occupancy, computer, office equipment, miscellaneous, catering process and lighting gains are lumped together into a single value. Solar gains are still calculated in the usual way.Note that with Lumped gains you cannot generate Temperature distribution and Comfort simulation output data.
Early - gains can be defined separately under various categories (see above).
Detailed - gains are specified by defining each individual item of equipment in each zone on the Equipment tab. If you select this option then DesignBuilder will automatically set the Timing model option to Schedules . Note that this option was developed for creating very detailed models of existing buildings based on survey data. Entering this data for a large building is very time-consuming and in most cases you will be better served by the Early gains option above.

Note: When using the Lumped Gains model option, Comfort data is not generated because in EnergyPlus the request for comfort calculations is made in the 'PEOPLE' statement and this is not used with Lumped gains.

Internal gains operate with occupancy

Check this option if you wish the timing of internal gains to be the same as occupancy. Unchecking the option allows you to set the timing of each type of gain individually. For example there may be low levels of emergency lighting and some IT equipment usage while the building is unoccupied.
