FINE HVAC’s advanced BIM technology will increase your productivity. Using our smart 3D modelers and libraries of 3D BIM objects you will be able to draw the building and its HVAC services much faster and easier. The close interaction of our Calculation module with the BIM model will help you to make all the calculations directly from the model. 




FineHVAC will simply read the BIM model (created from scratch or imported from other BIM software) to understand the project, the physical properties of the BIM objects, proceed to calculations and finally update the drawings with the calculations results.



Fine HVAC belongs to the 4M BIM Suite of software for Architecture & Engineering. Embedding the powerful 4MCAD engine and using DWG as its native file format in an AutoCAD-like environment, FineHVAC is renown to be the BIM software offering the easiest transition and high productivity features for only a fraction of the price of its main competitors. Unlike in other BIM software, Fine HVAC’s advanced and very intuitive BIM technology does not come at the expense of speed, it is just the opposite: you just need to draw a few single lines and the software will do the rest.



Fine HVAC automatically locates on the view plan the respective installation components (i.e. heating units, fan coil units, air-duct grills etc), through several expert rules that consider among others, the user’s preferences (e.g. radiator preference order, window height control, limit for additional radiator etc).




At this stage of the project, the pipes just need to be drawn as single lines. Commands like “Double Pipe” (e.g. induction – return), “Parallel to Wall” or “Parallel to Points” accelerate significantly the installation drawing while all connections are automatically created through the “magic” autorouting commands (e.g. 2-3 movements are enough to connect a group of grills to the vertical airduct column).



Fine HVAC’s Calculation module will read the physical properties of the BIM objects in your project to calculate the thermal losses and cooling loads space by space. It will also recognize the networks and receptors you designed and help you to calculate the air-ducts and pipes taking into consideration flow rates, pressure drops and more. Results are sent back to the drawing and exported in a calculation report you can customize.



After proceeding to the design of the network and calculations our MEP Software will let you generate all the technical drawings and reports you need.



Our MEP Software will generate for you the vertical diagram of the project in a DWG drawing you can further modify and/or share.

The BIM model of the Building will be updated with the results of calculation to define the size of the pipes and air-ducts but also with symbols and designations. As a result you will be able to generate floor plans in DWG showing all the receptors and networks you have defined. In addition FineHVAC generates axonometrics and 3D piping and airducting drawings with all the details on them.



Fine HVAC will generate a document with the calculation results and the bill of materials describing the quantities of reach of the elements required to build the HVAC systems. The template of this document can be customized and you can chose which results you want to display.



Following the International Standards and Regulations, Fine HVAC enables the user to select the applying methodology. In each case, the package utilizes the more advanced techniques and mathematical models for maximum accuracy, speed and reliability in calculations (e.g. analytical system of psychrometry equations, model of hydraulic simulation etc). Here are some examples:

  • Cooling loads: Ashrae RTS 2013 – Ashrae CLTD – Ashrae TFM – Carrier
  • Heating loads : Ashrae 2013, EN 12831, DIN 4701
  • Air-ducts : Equal Velocities – Equal Pressures – Static Regain Method




GCAD is the 4M BIM Interface Component which helps the energy designer to interact with energy calculation software Components within a user friendly integrated environment. GCAD has been developed according to the 4M BIM Suite standards to generate automatically the input data for existing BES modules (like for example 4M-KENAK) regarding the building envelope and particularly the geometry parameters of the building elements (such as floors, roofs, walls, openings etc). In addition it provides also a series of other building parameters such as the building location and orientation, shading information and many others. More specifically, GCAD:

  • Provides a user friendly CAD interface, seeing that the model shaping and design accuracy are directly applied on the real 3D model of the building. In fact, the manipulation of intelligent objects, rather than cad entities, facilitates the whole building design process as it speeds up any modification, made easily by the user on a 3D BIM environment.
  • Is based on the 4MCAD engine, offering all the CAD features and functions as they have been introduced by AutoCAD®, in order to be already known by the majority of the CAD users.
  • Embeds a detailed shading model considering the building model with respect to the neighboring buildings and other outdoor objects.
  • Supports the open communication, due to its full compatibility with both, the DWG (Autocad® files) and IFC file formats (Revit® files, Archicad® files etc.). This means that if a DWG file or (even better) an IFC file is available for an existing building, then the building envelope is practically ready to be properly introduced into the modeling software for the energy simulation.

The synergistic collaboration of GCAD with existing BES environments (like 4M-KENAK) makes the building energy design familiar providing the user with the flexibility to study alternative energy design scenarios.
