Heat load calculation

liNear Building Heating

Heat load calculation related to EN 12831

Heat load calculation


For the detection of the heat load of a building according to standard, a physical model of the building is to be detected structurally. Such a model includes the building materials, the room components, the geometric segmentation into storeys and rooms, and the temperatures. liNear Building features diversified input help such as tables, references of the standard, copy functions, quick dimensionings, etc., which are available to you to shape the process in an optimum way.

In the process, the program affords you on the one hand the necessary flexibility to make modifications to the progress of construction with a minimum of effort, and to update the construction on the other. The calculation results are output to the form sheets according to EN 12831.

Features

Heat load calculation according to international standards

Calculate the heating load not only according to the European Norm (EN 12831) but also by other standards. There are also heat load calculations according to national standards available for Austria (ÖNORM H 7500-1 (2015), Switzerland (SN SIA 384.201), France (NF P 52-612/CN), Russia (СНиП 41-01-2003 )and Turkey (TS 2164).

Choose predefined climate zones or create new

In order to obtain realistic results, the climate zone of an object is relevant. Select either from the large selection predefined places from all over the world or define new locations and areas.

Use liNear Building with Revit

All modules of liNear Building can be used in Revit with the help of the Building AddOn Revit Interface. The interface establishes direct data sharing between these two programs.

Drawing the dimensioning into your CAD

Dimensioned radiators can be taken and labeled in floor plans, as well as detailed installation plans for designed floor heating systems. Associative labels are automatically updated when changes appear.

Radiator design

With the use of the integrated extensive radiator databases a quick radiator dimensioning is possible in an easy way. All radiators in the building suitable for the calculated heating load will be used. In the detailed design mode you have all possibilities to determined each individual radiator exactly to the respective local requirements.

Optimized data entering

Easily create and copy sections, storeys, apartments and rooms and with the use of standard components this optimized data entering leads to fastest possible detection. Information and error logs allow you to navigate in the project by double-clicking.

Material listing

The complete material listing for radiators and panel heating systems can be exported in the ASD, Excel, GAEB and UGS formats for further processing in the offer or tender. The material determination is made automatically and continuously.

U-value determination

The tabular and graphical definition of room components such as walls, ceilings, windows and doors using the building materials table allows the quick and easy calculation of U-values. Including display of the temperature profile in the layer structure.

Creating standard components for a faster input

The ability to create standard components leads to faster and correctly input of the building geometry. Through the meaningful use of variables for room components, temperatures, etc. you parameterize your building, thus preserving maximum flexibility for changes during the planning process.

Takeover of all building datas from your CAD

With the Desktop AddOn Building Manager the entire building geometry can be taken automatically from AutoCAD or Revit, including room or adjoining temperatures.

Panel heating calculation

Take advantage of the integrated data sets of the leading manufacturers of panel heating and cooling systems. Variable system configurations with detailed performance data determination according to EN 15377 are supported as well as the calculation of wall and ceiling heaters. Even concrete core temperature control and module systems can be dimensioned.

Certified components catalog

The detailed design of system components such as radiators and panel heating and cooling, domestic ventilation systems, etc. based on real products leads to complete parts lists for the compilation of tender documents.

Direct connection to your CAD program

liNear Building as well maintains a constant dialog with your drawing solution. Interfaces to AutoCAD and liNear Desktop (including CADinside versions) or REVIT enable efficient working. The dimensioned products such as radiators or panel heating are automatically supplied to the drawing program where they are implemented graphically. By this means you may perform the calculation on the basis of your drawing as well as transfer the dimensioned products from the calculation to the drawing – a winning team.

Flexible building detection

The detection of the building is usually performed per room and may optionally be carried out automatically either in tabular form, CAD-based, or via the liNear Desktop AddOn Building Manager. Building models created in Autodesk REVIT may be imported directly via the Building AddOn Revit Interface. Thus, manual detection effort is no longer required!

Complete U-value calculation

You may calculate and understand the U-value easily. The temperature profile may be displayed graphically as well via an image of the wall construction. Whenever U-values are edited, the corresponding calculations are automatically updated.

Same modell for all certificates

Whether heat load, cooling load or domistic ventilation is concerned, liNear Building is the suitable program for you. A single data model for all modules enables you to save considerable time. Cumbersome double entries are history.
