System Type defines the HVAC system used in the building. Each System Type includes an Air, Heating, and Cooling system type that fully defines the elements of the building's HVAC (or mechanical) system. cove.tool selects a default system type depending on your project's location and energy code, however, the user has full control to customize to meet any project needs!
System Types in cove.tool are named with the following scheme allowing for quick and easy assignment of detailed design inputs.
'Air System w/ room units' + 'Heating System' + 'Cooling System'With eleven air system options, six heating systems options, and seven cooling systems options we have a total of seventy-two available system type options. These systems provide the basis for comparison when optimizing a building's HVAC systems. If you are exploring a system that isn't described below, just reach out to our expert for help in getting your system modeled!

Selecting a System Type will populate several fields on the Building System tab, providing a reasonable starting point for the project team. It is recommended that the project's mechanical engineer review these inputs to confirm they match the specific design intent of each project.
