Tas Engineering has a modular design, with dedicated programs serving a specific purpose, facilitating a methodical workflow.

3D Modeler

For creating building models for simulation & performing daylight analysis.

DWG Import

Create geometry by tracing around floor plans.

Daylight Calculations

Can be performed and viewed in the 3D modeler, to get instant feedback on a design.

gbXML Import

Intelligent gbXML import can repair common problems with geometry enabling a BIM workflow

Rendered Views

Photorealistic 3D rendered views can be generated using the daylight engine.

Daylighting validation information can be found here >

Building Simulator

For adding apertures, internal gains, constructions and performing a dynamic simulation

Dynamic

Fast, accurate hourly dynamic simulation

Reusable Databases

Re-use construction, internal gain and calendar data for an efficient workflow.

3D Visualisation

Quickly identify zones and where constructions, apertures and building elements are assigned.

Utilities

Collection of utilities and wizards make performing common tasks quick and easy.

The Building Simulator can be used to perform overheating analysis, calculate heating and cooling loads, calculate air flows and more.

Tabular Export

Export hourly data for zones, building and surfaces to excel for detailed analysis

Generate Reports

Use results viewer files as the input to our report viewer.

3D Export

Export pictures and videos with intelligent colouring and labels that reflect various metrics

Clear Charts

Fully customisable charts make it easy to present complex data clearly and identify trends​

Systems

Powerful HVAC modeller for calculating actual energy consumption based on the demands predicted by the Building Simulator.

Component Based Plant Modeller

Add, delete, or edit individual components in the system. Create custom systems and save them for future use.​

Editable Control Logic

Control component operation based on a wide range of parameters to accurately imitate real-life system behaviour.

Systems Wizard

Pre-built airside and waterside systems are available through the Systems Wizard, including 90.1 baseline systems.​

Detailed Results and Report Generation

Interrogate the results in detail with graphs, tables, and psychrometric charts. Automatically generated reports give system setup details and sizing data.

Ambiens 2D

A Computational Fluid Dynamics engine specifically for buildings

Can be driven by results from Tas Engineering (pictured here)

Traditional CFD packages are notoriously difficult to use as they are used to analyse a wide range of problems. Ambiens 2D is different. Ambiens 2D is a CFD package with a very specific purpose – modelling airflow in buildings, and as a result, it’s incredibly user friendly. 

Analyse Complex Airflows

Ambiens 2D allows you to determine the effect of local air conditions on occupant comfort, taking into account:

  • Radiant temperature from surfaces
  • Local speed of airflow
  • Local temperature of airflow
  • Humidity 
  • Metabolic rate
  • Clothing

A room temperature can be misleading

A large space with hot or cold radiant surfaces or with air that is poorly mixed can have some areas that are much warmer than others.

The space may also have cold draughts. 

With Ambiens 2D you can quickly identify potential problems and tweak the design of the space to eliminate them efficiently.

Graph-like interface

Geometry is created by drawing a 2D slice through the space being analysed. 

  • Spaces are 1m in depth.
  • Each cell in the graph-like interface represents a fixed distance.
  • Internal gains can be added by drawing them anywhere within the space. 

Surface temperatures can be set by clicking on the walls.

Create videos

You can export videos showing how parameters vary over time such as:

  • Dry bulb temperature
  • Relative humidity
  • Air speed
  • Mean radiant temperature
  • Resultant (operative) temperature
  • Percentage People Dissatisfied (PPD)

The scales are fully customisable, as is the visual update interval.
