• Building materials input
The program allows the user to easily draw the building’s envelope with or without an architectural drawing. It provides a number of standard building panels and allows for custom assembly of building panels to meet the user's specifications. When an architectural reference plan is inserted, two different commands are available to help the designers in converting simple AutoCAD® lines in walls with their thermal properties.
The user need not draw three-dimensional objects, just lines and symbols which represent all different structures (window, door, room, etc.).
The program then will make the necessary calculations and will create the three-dimensional model of the building.

• Roof drawing
In order to accurately calculate the volume and the building's thermal exchanging surfaces it is necessary to draw a pitched roof, if it is present in the original architectural plan.
|
|
• Cooling and heating load calculations
The program performs residential and the non-residential heating and cooling load calculations for each building panel and room of the project (TFM-Transfer Function Method and RTS-Radiant Time series methods) according to the 2005 ASHRAE Handbook-Fundamentals. Geographical weather data is included in an internal database.

• Fan coil and piping distribution systems
Drawing these types units in the project plan is simple because it requires just one mouse click. Depending on the thermal load of the room, the program will calculate the number of elements for the radiators and the fancoil size. If the project is not based on thermal calculations, the user can manually enter the power capacity for each thermal unit. This makes it possible to size a piping distribution without graphical input of the building.
The piping distribution can contain a manifold, and the return distribution can be compensated, or symmetric.
When the circuit layout is completed, the user can run the calculation command. The designer can size all pipes drawn in the circuit or he can verify them. Moreover, it is possible to balance the circuits using the valves or fixing the pipe diameters.
Finally, in order to determine the actual capacity of the heating unit, the program is able to calculate the true water flow rate dependingon the pump's operating curve.

• Radiant floor heating design
The program allows definition of panel types and floor temperatures for sub-areas within each room.
Following the ASHRAE standard calculations, the program will automatically calculate and draw the circuit layout pattern choosing among serpentines, two- and three-way serpentines and counter-flow options.
The user can also manually enter the rooms' heat loss value; this is for sizing and drawing the FHS without any heat loss calculation.
Finally, in order to balance all circuits, the program will also calculate the valve position on the manifold, calculating the total system flow rate and pressure drop.
Calculates required water temperature, flow rate and pressure drop across each circuit.Summarizes tubing length requirements, flow rates and pressure drop figures.

• Plumbing distributions
It is possible to design and size all plumbing distribution, with either hot or cold water.
The resulting calculation is in accordance with International Plumbing Code (IPC) or DIN 1988 standards.
|
|
• Ductwork systems
The duct module allows the users to draw and size the ductwork system according the following ASHRAE calculation methods: the equal friction method and static regain method. It is also possible to verify an existing system or balance the ductwork net with or without dampers. The program can also calculate the pressure drop regarding to the Fan System Effect.
If an Air Handling Unit is part of the project, the program will 'read' the air flow rate directly from the specific rooms. Alternatively, the user can manually fix these values on the diffusers.

|
• Bill of materials
The program will create the project bill of materials automatically. By running a simple command the program will generate a list of all objects drawn in the project plan.
It allows for complete and accurate estimates using current catalog data. System components are displayed pictorially along with article numbers, descriptions and list prices. List price multiplier can be specified and applied to all selected materials. Labor rate and time estimates can be included for complete quotations. The user can create a link (with the drag & drop command) between the current object and a price code retrievable in a customizable price list. The report file can be in MSExcel or Rich Text Format.
