BUS++

New generation platform for building energy, ventilation, noise level and indoor air quality simulations. A network assumption is adopted, and BUS++ allows both steady-state and dynamic simulations on a desired level of accuracy.

BUS++ includes modern solution routines and has passed the most commonly used rigorous air flow and heat transfer test cases. However, only a limited number of special applications are completed.

Keywords

energy performance, ventilation, air flow, indoor air quality, noise level

Validation/Testing

N/A

Expertise Required

Special expertise needed for utilizing all potential calculation features. Common knowledge of building components needed for using special applications with graphical user interfaces.

Users

20 users in VTT Building Technology and other companies in Finland.

Audience

R&D, scientists, designers, education.

Input

Reads process information from an ASCII input data file. Graphical, dialog based user interfaces are available for special applications only.

Output

ASCII output files for pressure distribution, air flow rates, node temperatures and contaminant levels. Graphical output for special applications and demo versions only.

Computer Platform

PC compatible (Windows 95/NT).

Programming Language

C++

Strengths

Highly flexible simulation environment and effective solution routines together offer a productive foundation for both development of a general simulation toolbox and tailoring applications for special needs.

Weaknesses

Testing and development are still ongoing. BUS++ does not include facilities for CFD simulations.
