Co-simulation for performance prediction of integrated building and HVAC systems - An analysis of solution characteristics using

Integrated performance simulation of buildings and heating, ventilation and airconditioning (HVAC) systems can help reducing energy consumption and increasing occupant comfort. However, no single building performance simulation (BPS) tool oers sucient capabilities and exibilities to analyze integrated building systems and to enable rapid prototyping of innovative building and system technologies. One way to alleviate this problem is to use co-simulation to integrate dierent BPS tools. Co-simulation approach represents a particular case of simulation scenario where at least two simulators solve coupled dierential-algebraic systems of equations and exchange data that couples these equations during the time integration. This article analyzes how co-simulation inuences consistency, stability and accuracy of the numerical approximation to the solution. Consistency and zero-stability are studied for a general class of the problem, while a detailed consistency and absolute stability an...
