The EnergyPlus engine used for the loadmodeling.tool simulations is both powerful and highly customizable. The customization provide control over the resolution of results, run times and calculations methodologies. Currently a curated array of settings are open to users to adjust parameters such as time step. The remaining settings are set to standard defaults to reduce complexity of running each simulation In future more settings will be opened along with clear guidance on when and why certain settings may be adjusted.

### Settings Page Guide

### Currently adjustable settings

Heating Sizing Factor - the Heating Sizing Factor is applied globally to all peak heating results. The resulting load value can be viewed in the `load_summary.xlsx`

export as `Room Heating Safety`

.

Cooling sizing Factor - the Cooling Sizing Factor is applied globally to all peak heating results. The resulting load value can be viewed in the `load_summary.xlsx`

export as `Room Cooling Safety`

.

Timestep - Defines the calculations per hour. The default is 6, so 6 calculations per hour, or a calculation every 10 minutes. More calculations per hour provide more resolution to fast changing conditions, however increase simulation run time.

### Currently standard default settings

Minimum warmup days - 2

Maximum number of warmup days - 25

Temperature convergence tolerance - 0.4

Loads convergence tolerance - 0.4

Solar distribution - FullExterior

Inside surface convection algorithm - TARP

Outside surface convection algorithm - DOE-2

Heat Balance Algorithm - ConductionTransferFunction

Zone air heat balance algorithm - ThirdOrderBackwardDifference

Radiance parameters - Coarse
