Archive of terminals, special pieces, MEP object configurator | usMEP.HVAC | ACCA software

You have a vast archive of terminals, special parts... and an MEP object configurator

usMEP.HVAC provides for free a rich BIM object library containing various types of pipes, ducts, fittings (bends, joints, transitions, endcaps), special parts, terminals, control valves and dampers.

Furthermore, with the BIM configurator for MEP objects, it is possible to create any component while drawing the system.

After configuring the object, you can "match" it with the corresponding market product, upload it to the catalog, and call it automatically in all new projects.

It is a unique and innovative method for object search, based on defining its functional characteristics for the project and offering maximum freedom without being restricted to catalog objects.

Automatically get HVAC system sizing with custom 3D views of results | usMEP.HVAC | ACCA software

Obtain automatic calculation of the HVAC system

usMEP.HVAC allows calculation of hydronic systems for heating and cooling (summer calculation coming soon) and air handling systems for ventilation, air conditioning, and thermal ventilation, operating both in winter and summer.

With usMEP.HVAC you can perform

  • sizing of system components (pipes, ducts, special parts, terminals, control valves, and dampers);;
  • circuit balancing;
  • verification of the HVAC BIM model designed with Edificius, without modifying the size of MEP objects;
  • recalculation of flows actually carried by the pipes;
  • customization of every system element and adding additional information;
  • verification of supply by comparing the system characteristic curve with that of the pump or fan.

usMEP.HVAC allows sizing or verifying one or more calculation circuits within the same project.

The software performs a pre-sizing of the circuit and a balancing with automatic regulation of valves, dampers, and terminals.

Pre-sizing calculates the diameters of pipes or ducts based on the fluid flow each must support and maximum values set for velocity and pressure drop.

This procedure calculates all data (spacing of radiant panels, temperatures, flows, velocities, pressure losses, head and static pressure) and minimizes imbalance between circuit branches by reducing pipe and duct diameters or using control devices (valves, dampers, terminals).
