Tas Engineering

Industry-Leading Building Modelling and Simulation

Tas software is developed by Environmental Design Solutions Limited (EDSL) which was formed in 1989. Tas is an industry-leading building modeling and simulation tool. Capable of performing dynamic thermal simulation for the world's largest and most complex buildings, Tas allows designers to accurately predict energy consumption, CO2 emissions, operating costs and occupant comfort.

The interface between Tas and Cymap software is a 2 way process.

From the Cymap building modeller you can export all the zones/room geometry created to create the Tas building simulation (TBS) file which can be used for analysis. This will be used instead of creating the 3D model in Tas to run the simulation.

Once the dynamic simulation has been completed in Tas you can import these results back into Cymap, to enable building services sizing and design to be undertaken.

Tas Engineering

 

The complete Dynamic Building Simulation package.

Tas Engineering has a modular design and is split into three main programs, the 3D Modeller, Building Simulator and Results Viewer. The intuitive Windows interface has features such as undo/redo, drag drop, context menus etc. all making the software more productive and easier to use. The program architecture clearly defines the simulation workflow process facilitating methodical working by the Engineer.

3D Modeller

The 3D Modeller is developed specifically for creating building models for simulation. You can use it to draw buildings that are still only at the rough outline sketch stage, or import CAD drawings to generate more detailed models. From this model you can create rendered 3D views that display comprehensive shading. Tas will even calculate sunshine penetration through the interior of the building between spaces. The model can be exported to 3rd party programs via a 3D dwg export facility.

Building Simulator

Each window, door, ventilator or other aperture has its relative altitude and orientation automatically calculated to give a potential airflow network through the building. This means that natural ventilation is simulated automatically, and you choose which apertures are open, when, and by how much. Dynamic control of apertures can be implemented using control functions. 

Results Viewer

Any combination of parameters from any number of Zones and Surfaces can be displayed and compared in a tabular and graphical format.

The unified database system used throughout the package enables external data access by any Automation client (e.g. Word, Excel etc.). Third party applications are able to integrate easily by using the automation interfaces to input and extract data. Even very large simulation data files running into hundreds of megabytes can be manipulated with great speed by this technology.

Comprehensive Databases

Construction materials and glazing types can be allocated from the comprehensive databases. These have their dynamic response automatically calculated in the model. The occupation of the building is represented by a calendar, with different day types having varying schedules of use. The final ingredient that brings the building model to life is the climate data used to drive the simulation. Tas Building Designer gives you access to over 2,500 recorded weather sites worldwide. The data consists of hourly values for solar, temperature, humidity and wind speed and direction.

 

Tas Videos

Tas and gbXML

This video demonstrates how geometry data from BIM models (e.g. Revit Architecture) can be imported in gbXML format in order to carry out thermal analysis. Once imported, the model can be edited directly in 3D within the Tas 3D Modeller. In the event of a design revisions, an updated gbXML file can be imported without losing the changes made in Tas. Tas will also 'heal and forgive' mistakes such as exposed holes in the gbXML geometry.

 

Tas Systems

This video demonstrates the latest component-based plant modelling toolkit for Tas. Detailed HVAC schematics are created from the extensive component library using an intuitive drag-and-drop interface. Controllers can then be added and combined to model even the most complex systems control logic. Tas Systems also includes a Project Wizard to assist in quickly creating basic systems that can later be edited by the user. Simulation reports can be exported in a wide variety of image and data formats.
