- Abstract
- A non-proprietary building system simulation program called HVACSIM+, which stands for HVAC SIMulation PLUS other systems, has been developed at the National Bureau of Standards (NBS) in an effort to understand the dynamic interactions between a building shell, an HVAC system, and building controls. HVACSIM+ consists of a main simulation program, a library of HVAC system component models, a building shell model, and interactive front end input data generation programs. The report presents the overall architecture of the HVACSIM+ program, algorithms used in the main simulation program, a brief discussion of the numerical methods used in solving a system of non-linear simultaneous equations, integrating stiff ordinary differential equations and interpolating data and descriptions of the building shell and zone models.
