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.
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
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.
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.
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 Engineering 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.
