TAS Software

TAS is a complete design tool for dynamic thermal simulation of a building, allowing us to accurately assess and optimize a building’s energy, comfort, and environmental performance. It is one of the most powerful, commercially available simulation programs in the industry.

TAS has the capability to create a detailed and realistic three-dimensional building model, and simulate building and heat transfer attributes that other commercial simulation packages such as TRACE, HAP or even DOE-2, TRNSYS or BLAST are not programmed to do.

The three-dimensional structure of the TAS model allows the software to accurately simulate fairly complex thermal phenomena such as radiant heat transfer, inertia effects of building mass, and buoyancy–driven air flows throughout the building. These simulation capabilities are essential to properly model and optimize a variety of Sustainable Design Concepts that have been traditionally designed intuitively, often lacking sound engineering analysis.

TAS also includes the so-called Ambiens module, two-dimensional CFD software that allows the user to generate a detailed view of the microclimate across a section of an internal space. The output provides clear visual displays for two-dimensional variations in a variety of temperature, air flow and comfort parameters, and allows for accurate assessment of the comfort conditions within the occupied portion of the space.

Combined with the Sustainable Design expertise of our key staff, TAS provides us with the capability to accurately model a variety of non-conventional and creative energy efficient designs such as:

• Radiant Slab Heating and Cooling – “Thermo-Active” slabs, evaporative cooling, etc.
• Displacement, Natural or Mixed mode Ventilation – airflow patterns, stratification, stack effects, etc.
• Passive and/or Active use of Building Mass – passive Solar heating, load shifting and energy storage, etc.
• Advanced Building Envelope Designs – “Double Skin”, passive or active external shading, etc.
