Workflow for
Heating Design

Exemplary Workflow for Heating Design with Autodesk Revit

With the liNear solutions, an integrated workflow in heating design is guaranteed. From MEP model creation, building analysis and heat load calculation to product design and pipe network calculation, you can design fast and efficiently with liNear on Revit.


Step 1: MEP Model Creation

Ideally, you already receive the architecture as a Revit model which can be used to create a MEP model when designing the building services engineering. With the help of liNear, you can use the elements from the architectural model (e.g. levels, rooms, materials) and add further information to them. Automatically create the required storeys including work levels and use efficient tools to create spaces, zones, area plans and views. The liNear Parameter Manager, allowing the determination and assignment of parameters, is also included.


Step 2: Building Analysis

When specific MEP information have been added to the architectural model, it is ready for design and analysis. The model is transferred to liNear Building and analyzed. The program checks the model and reports any missing values. Missing data (e.g. U-values) can now be manually added or calculated. You have the choice whether you work with self-defined values or whether these are replaced by "better" values as soon as they are available. All values can also be transferred back into the model. The representation of the model in building parts, levels and rooms enables quick and easy orientation. The detected building model is the basis for all load calculations and dimensionings.


Step 3: Heat Load Calculation

Once the building has been completely detected and analyzed, the heat load is calculated immediately. The calculation is done for the entire project as well as for storeys or individual rooms. With liNear not only the German heat load calculation but also international methods are at your disposal. Optionally, air volume flow rates can also be considered in the heat load.

Step 4: Radiator and Panel Heating Dimensioning

Based on the determined heat load, you can immediately continue to dimension radiators or convectors or the panel heating systems. In extensive manufacturer libraries you can select your products already before the dimensioning is made. You can choose between a quick or a detailed dimensioning. With one click, dimensioned components are transferred to the model. Radiators and convectors are automatically positioned under the windows and the floor heating is drawn according to the area plan. Adjustments can be made in the model or in the dimensioning process and all changes are transferred bidirectionally.

Step 5: System Creation and Pipe Network Calculation

After you have transferred all components to the model and positioned them according to your requirements, continue with the construction of the pipe network and the heat supplier. Consumers are connected and the detailed design of the pipe network follows. Select neutral or manufacturer-specific components from the library and define the individual components according to your specifications. Start the pipe network calculation. If there are still possibilities for optimization, the program informs you so that you can implement them immediately. Finally, the network is redimensioned. With fixed pipe dimensions, you can also calculate existing systems and optimize or extend the network. A void planning with powerful collaboration tools simplifies the coordination process with architects and structural engineers in both closed and open BIM projects.


Step 6: Labeling and Output of Results

With the automatic labels you can write the results of your design work directly into the model - quickly and simply. You can define and reuse labels globally, per component group or for individual elements. It is also possible to add your own parameters, which can be included in the labels. All results, e.g. bill of quantities, pipe network calculation, heating load results or hydraulic balancing, can be displayed in different formats. All information is saved directly in the model. The final MEP model is provided for the BIM process. The IFC format is also available as an option.
