Importing gbXML data into Tas

Posted on

The Solution for Reusing gbXML Geometry

Tas has a quick, robust, and versatile gbXML import capability which allows files to be imported quickly, inconsistent geometry automatically identified and repaired, and further edits to be made.

Modified geometry can be exported from Revit and merged into the Tas 3D file, retaining any changes made by the user.

Imported gbXML geometry can be used as the basis for any Tas calculation type, including daylighting and CBDM, UK Building Regulations, detailed HVAC analysis, and more!

EDSL can provide extensive guidance on the subject of gbXML re-use, including videos, example files, and documentation.

EDSL at AIRAH Building Simulation Conference November 2017

EDSL were sponsors of the AIRAH Building Simulation Conference in Melbourne, Australia.

EDSL’s delegates met academics and engineers from Australia and elsewhere and demonstrated the advantages of using Tas for building thermal analysis, daylighting, and advanced plant modelling.

EDSL were pleased to offer promotional free trials of Tas to conference attendees.

EDSL at IBPSA Building Simulation Conference August 2017

EDSL were silver sponsors of the IBPSA Building Simulation Conference in San Francisco, USA. Over the three days of the conference our delegates took part in many interesting discussions with academics and engineers from around the world who wanted to learn about the advantages of using Tas for building thermal analysis, daylighting, complex plant modelling, and Ashrae 90.1 projects.

Michael Sawford, Vice President of EDSL USA, was co-presenter of two sessions on building performance metrics and energy modelling outputs.

EDSL were pleased to offer promotional free trials of Tas to conference attendees.

Interoperability with EnergyPlus

Posted on

In the latest version of Tas (v9.4.2) the software’s capability to import and export IDF files has expanded again.

  • Exported IDF files will now include an IdealLoadsAirSystem object for each zone, allowing immediate simulation of room loads in EnergyPlus.
  • Surface shading data can now be imported from EnergyPlus CSV files

Tas can import or export data between the TBD and IDF formats, transferring the following data types:

  • Building geometry
  • Internal conditions (gains, schedules, thermostats, humidistats)
  • Construction data (building fabric)

EPW weather data can also be imported.

This capability allows cooperation on projects between Tas and EnergyPlus users, and provides a way for EnergyPlus users to become familiar with Tas using one of their existing projects.
