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.
When specific MEP information has 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.
Once the building has been completely detected and analyzed, the cooling load is calculated immediately. If you have already calculated the heat load, you can of course use the building model detected for it. Both the German method according to VDI 2078 and the international method according to ASHRAE are available for the dynamic calculation. After defining design temperatures, shading and usage profiles, the program displays the results for the entire project, individual building parts, levels and for all rooms. The output is subdivided into the dry (residual) cooling load, the cooling load from panel cooling, the cooling load from AHU/ supply air system and the total cooling load.
After determining the cooling load, use the liNear dimensioning for cooling systems to cover the demand. This dimensioning is available for convectors and panel cooling systems. From 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. Cooling convectors are automatically inserted and the panel cooling is drawn in according to the area plan.
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 cooling supplier. The dimensioned consumers are connected and the pipe network is designed in detail. 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.
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 such as bill of quantities, pipe network calculation, cooling load results or hydraulic balancing are output in various 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.
