Hysopt BIM Syncer can create a P&ID model (calculation model) from a Revit model. It uses a smart algorithm that first identifies the end units (heat emitters) in your system, such as radiators, fan coils, or floor heating. Then, it analyses how the system is connected with components and pipes, such as pumps, valves, or fittings. The algorithm stops when it reaches a production unit, such as a boiler, chiller, or heat pump. This way, Hysopt BIM Syncer can generate a complete and accurate P&ID model of your system.
...
The generated Hysopt model is created with “Base Circuit placeholders”. (What are base circuits?)
A placeholder is a useful tool when we want to generate a Hysopt model in the Hysopt BIM Syncer without knowing the classification of the component or without fully drawing the components (eg. floor heating). A placeholder allows us to assign a generic type to the base circuit, such as a production, component, pump, regime changing and end units without specifying its type (eg. component → valve → on/off valve). This way, we can still model the P&ID of the system, even if we do not have a complete classification of the component. A placeholder can be replaced later by a specific component if needed.
because sometimes components are not completely drawn (e.g. floorheating , see next)
Production placeholder
...
Production placeholder
Production placeholders are used for replacing a production unit, such as a boiler, chiller, or heat pump
...
Component placeholder
Component placeholders are used for replacing components, such as three-way valves, strainers, or on/off valves
...
Pump placeholder
...
Pump placeholders are used for replacing pumps. If the classification of the Revit component of the Pump is not present. The Revit component will be generated as a component placeholder.
...
Regime changing placeholder
Regime changing placeholders are used at locations in the system where components or connections will affect the temperature regime in the system.
Component
Regime changing component placeholders are used for components, such as heat exchangers, heat interface units, low loss headers
...
Distribution unit

...
Type 2
...
End unit placeholder
...
End unit placeholders are used for replacing end units, such as radiators, floor heating, or fan coil units
...
Replacing placeholders
For most of the calculations supported by the Hysopt BIM Syncer we don’t do not necessarily need to replace these placeholders
...
Unprocessed mixing/dividing point in the system. Maybe you need to mark some components as endunit on these branches
...
We found a branch with an unknown location," this might indicate that the classification type of the pipe segments is not consistent in our BIM model
This point in the system has {number} pair of branches, this is not supported yet by the generator
Errors
No end units found
...
Successful Hysopt model generation
...
all HVAC related BIM elements were processed during the generation
...
Generated model contains parallel branches, this is not fully supported yet in Hysopt
