Exemplary workflow with Autodesk Revit

We guide you step by step through the exemplary workflow for working with liNear on Autodesk Revit, from building preparation to result output.


Step 1: Modell Enrichment

Ideally, you will receive the architecture as a Revit model and use this as the basis for the MEP model, in which your MEP design is then carried out. If you only receive 2D plans, our architecture tools in liNear Desktop give you the opportunity to create the architecture in 3D with minimal effort. With the help of our tools you can comfortably create building parts, storeys, levels, auxiliary levels, rooms, MEP spaces and zones and enrich them with further information such as target temperatures or internal loads. The automated view control facilitates the work and creates order in the design. An analysis of the terrain approximation and the liNear parameter management to control and assign the parameters are also included.

Input

Architecture model or plan

Output

MEP-optimised architecture model including storeys, zones and MEP spaces 

      Work stages

  • Creation (not applicable) and enrichment of the 3D building model 
  • Create a storey table
  • Create MEP spaces
  • Zoning
  • Create first views and plans

Step 2: Building Analysis

After enriching the architectural model with MEP-specific information, the model is ready for design and analysis. The model is transfered and analysed in liNear Building. The program checks the model and alerts you both to errors within the architecture creation and to missing values. Errors in the architectural model can be communicated to the architect via the free liNear collaboration tool. Any missing data for the analysis (e.g. U-values) can be added or calculated manually. A clear display of building parts, floors and rooms enables quick orientation. The detected building model is the basis for all load calculations, certificates and dimensionings. 

Input

Architecture model with additional information for the calculations

Output

Building detection and analysis including the information required for load calculations

      Work stages

  • Automatic detection and transfer to liNear Building 
  • Communication of errors with other planning participants
  • Supplementing analysis-relevant values 

Step 3: Load Calculations

Once the building has been fully detected and analysed, you will start the load calculations. The program determines these for the project, the floor or individual spaces. The heating and cooling load calculation according to German or international standards is at your disposal, as is the certificate according to EnEV. The intuitive user interface enables the comfortable input of calculation-relevant data. The concept creation of a residential ventilation system and the associated calculation according to DIN 1946-6 are also possible here.

Input

Detected building with calculation-relevant values

Output

Heat load, cooling load, EnEV, Ventilation concept

      Work stages

  • Supplementing analysis-relevant values 
  • Evaluation of alternatives
  • Load calculation
  • Output of the calculation results

Step 4: Dimensioning

The automatic radiator or convector dimensioning as well as the calculation and dimensioning of panel heating/cooling systems are available for the dimensioning. In the area of ventilation, you can design the ventilation systems. Extensive manufacturer libraries enable product selection prior to dimensioning. Selected components are transferred directly into the model: Radiators and convectors under the windows and panel heating/cooling systems according to the area plan. Adjustments can be carried out in the model or in the dimensioning and can be adjusted bidirectionally.

Input

Load calculations

Output

Calculation/optimisation of the dimensioning

Transfer to model

      Working stages

  • Selection of components 
  • Dimensioning
  • Transfer into model

Step 5: System creation, calculation and collaboration

In step 5, you will construct the network and integrate the supplier. Consumers are connected and the detailed planning of the network follows. Select neutral or manufacturer-specific parts from the library and define the components according to your specifications. Then carry out the network calculation. If necessary, the program reports optimization options in the Issues and tasks tab. You can edit them, enrich them with information, and forward them using BCF (including IFC if required). Finally, the net is redimensioned. Slot and void design with powerful collaboration tools simplifies coordination with architects and structural engineers in both closed and open BIM projects.

Input

MEP Modell with dimensionings

Output

MEP model with optimized systems and the release of the required slots and voids

      Working stages

  • Net construction incl. components and supplier
  • Calculation, optimisation and redimensioning networks and installations
  • Coordination with architects and structural engineers concerning voids

Step 6: Labelling and outputting results

Write the results of your design directly into the model. Automatic labels help you to do this quickly and clearly. You can define and reuse labels globally, per component group or for individual elements. The addition of own parameters is also possible. These can be included in the labels and can be used for export. All results such as the mass determination, the detailed pipe network calculation, the heating load results or the hydraulic balancing are output in different formats. All information is stored directly in the model and the final  MEP model is provided for the BIM process. The IFC format is also available for this purpose. 

Input

MEP model with optimized systems

Output

Final MEP model for implementation into overall design and output of results  

      Working stages

  • Definition of labellers and selection of the exporting value
  • Labelling
  • Passing on the MEP model to the client
  • Output of results, parts lists, etc.
