loadmodeling.tool is the full featured load modeling and system design tool integrated with the cove.tool platform. The tool uses the EnergyPlus engine for detailed, room-by-room load calculations and HVAC system sizing. Models are accessed via a web-interface for quick performance and ease of sharing results. The entire model is exportable to OpenStudio and EnergyPlus native files for use or record keeping offline.

loadmodeling.tool integrates with the wider cove.tool platform to provide seamless connection between early-stage energy analysis and detailed room-by-room load modeling and system design.

  • The building type and energy code set on the Project Page determine the default Room Template and Envelope Performance values used

  • drawing.tool acts as the geometry creator/editor and defines the Rooms used for our load models. Envelope performance is also assigned here surface-by-surface. Room templates can be assigned here, however it's often more advantageous to assign these in the Room Templates data table.

The interfaces of loadmodeling.tool allow users to preform all tasks pertaining to creating and customizing a building load modeling.

  • The Room Templates page handles creation, customization, assignment and saving back to the library templates for rooms. This is where internal gains, set points and outside air flow rates are assigned.

  • The Schedules page handles creation and customization of all detailed schedules, which are assigned throughout loadmodeling.tool. Here specific schedules for equipment, lighting, occupancy, etc. are created for use or saved back to the library.

  • The Room Results page provides reporting of cooling and heating loads for each room in a model. A detailed breakdown of the load is provides in an easy to understand graphic. Full results can be downloaded from this page to a spreadsheet.

  • The General Settings page includes the high level settings of the model, such as heating and cooling sizing factors. The run simulation button, along with set custom weather file and download an .osm version of the model are all on this page.
