loadmodeling.tool is the full featured load modeling and whole Building Energy Modeling tool integrated with the cove.tool platform. The tool uses the EnergyPlus engine for detailed, room-by-room load calculations, and hourly simulations. 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 whole building load and energy modeling.
The building type and energy code set on the Project Page determine the default Room Template and Assemblies assigned.
drawing.tool acts as the geometry creator & editor and defines the Rooms used for the models. Envelope performance is also assigned here surface-by-surface. Room templates can be assigned here.
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 Project Data Editor page allows for in depth view into the project details. In version 2 zones can be created and assigned here, along with zone assignment to air systems.
The Ventilation Calculation page performs detailed Ventilation Rate Calculations for a variety of procedures. Use it optional, but enables additional reporting and control of the simulation.
The Air System Inputs page handles the creation from template and customization of Air Systems. Air Systems include all central and local equipment that provide the heating, cooling and ventilation to zones. Air Systems can be sized with the platform.
The Mechanical Plants page provides means to create from templates and customize the central plants of a building. Mechanical Plants act as heating and cooling sources that can be assigned to various components of Air Systems. Once assigned to systems, plant sizing results are calculated.
The Results page provides reporting of cooling and heating loads for each Zone, each Air System, and each Mechanical Plant in a model. Annual Energy Results are also available. 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 or PDF.
The Time Series Viewer enables in depth view of the hourly energy modeling results.
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.
