FineHVAC, the integrated software environment for Heating, Ventilation and Air-Conditioning Design, produces in a smart and automatic way the complete case study output of any HVAC project. Including all the calculations, technical reports, bill of materials and the full set of the final drawings, the program output is the result of the intelligent, synergistic co-operation, between its two Components, "CAD" and "Calculations".

Intelligent Building Design: The CAD Component of FineHVAC embeds IntelliCAD engine, providing full autonomy to its user. It recommends and draws projects through automated commands, the most important of which are listed below:

	Automatic Receptor Installation: FineHVAC automatically installs on the ground plan radiators, fan coils, air-duct grills etc. Moreover, this procedure follows expert intelligence rules, which are open to the user's preferences (e.g. radiator preference order, window height control, limit for additional radiator etc). The installation may also concern receptor systems on grids (e.g. grills on grid) while detailed ground plan layouts are automatically created.

	Automatic Pipe Drawing commands (autorouting): The commands "Double Pipe" (e.g. induction – return) "Parallel to Wall" or "Parallel to Points" etc 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).

Automatic Calculations directly from Drawings

	Through the subsystem AutoBLD the spaces are identified so that Thermal Losses, Cooling Loads and Heat Insulation are automatically calculated. This is possible even if the ground plan comes from another architectural package (DWG or DXF file) or a scanner (bitmap file), thanks to the "smart" identification commands.

	Through the subsystem AutoNET the E/M installations (pipes, cables etc) are identified and each network is transferred with its number in the calculation sheets, where it is immediately calculated providing the complete calculation issue.

Automatic Production of all the Project Drawings

	Vertical Diagrams: They are created from the ground plan fully automatically and in detail. Moreover, the user is enabled to select engine-room, legends, labels etc.

	Detailed Drawings: They are created from the required drawings, as for example the automatic conversion of the Air-duct network from linear into two-dimensional (with the dimensions resulted in calculations). Symbols and Designations (e.g. Single-Pipe System arrows, junction points – pipe connection circles, column direction arrows, up-down legends, comments etc) are also automatically inserted, perfecting the project drawings.

The Calculations Component of FINE (called also as ADAPT/FCALC) incorporates the more reliable calculating environment and the more solid scientific background. The package is granted highly among Electrical-Mechanical Engineers since it comprises the more reliable and guaranteed solution in Electrical-Mechanical Applications and the more valid program in Urban Planning. The recent version incorporates many innovations that verify its leading part.

Methodological Completeness

	ADAPT/FCALC is the only package that, following the International Standards and Regulations, enables the user to select the applying methodology (e.g. Carrier - Ashrae CLTD - Ashrae TFM Methods in Air-conditioning Loads, DIN77 - DIN 83 in Thermal Losses, Method of Equal Velocities - Equal Pressures - Static Regain in Air-ducts, VDI in Electrical Installations etc). 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).
