Building infiltration class

In the calculation of thermal loads Revit MEP offers us the possibility of regulating the flow due to infiltration. This rate with respect is regulated in three steps:

 

loose = 1,38 m³/h x m² – (0,076 CFM/Sq x ft)

medium = 0,69 m³/h x m² – (0,038 CFM/Sq x ft)

tight = 0,34 m³/h x m² – (0,019 CFM/Sq x ft)

none = 0 m³/h x m² – (0 CFM/Sq x ft)

 

It is important to remember that the surface on which Revit calculates wall surface is in contact with the outside. Here’s a video showing the comments:

Systemair Plug-in for AHU selection

Few manufacturers have developed their product catalogs for Revi MEP and in this post we talk about Systemair. Unlike others they didn’t send a huge full of families arranged at their discretion but a selection software for the AHU units and a plug-in for Revit that imports the file generated, as a family, in our project.

In the version I tested the families exported only had information about the  air connectors although the families parameters are not yet linked to the connector parameters.

The hydraulic parameters are not yet included, honestly do not understand why you skipped. As for the electrical parameters, as Systemair, not included by the installation of the equipment in situ are not typical configurations but still electricity consumption unchanged.

Manage the selection program has some difficulty and we leave Systemair experts who choose the conditioner that best suits our needs and send together with the financial offer SystemaAirCad file. For now this workflow is that we should lower.

Install the software

From their official website we download and install the software SystemairCAD selection, we will find in the “Global / Support / Software tools / SystemairCAD”. On the same page we have instructions on installing the plug-in for Autodesk Revit

IMPORT OF 3D MODELS TO AUTODESK REVIT

SystemairCAD is able to export a DMR file of a 3D CAD model.

A small plug-in have to be installed, to import the 3D model to Autodesk Revit.

The import plug-in together with instructions how to install it can be downloaded via the following link:

The purpose of the connection is to add Systemair air handling units selected with SystemairCAD into MagiCAD for Revit or Revit project and drawing.

Import an AHU

The plug-in offers two options for importing an air conditioner but we are going to focus only on the second, importing a file. “dmr” exported from SystemairCAD.

On the same page to download the plug-in found the Systemair Revit Plugin – Users Guide.pdf with details about the different ways available to import.
