Clarke describes a future vision of BPS with the following, most important tasks which should be addressed by the global BPS community.

Building performance simulation - Wikipedia

There are normally occurring uncertainties building energy simulation building design and building assessmentwhich generally stem from approximations in model inputs, building energy simulation as occupancy behavior.

Calibration refers to the process of "tuning" or adjusting assumed simulation model inputs to match observed data from the utilities or Building Management System BMS. Many papers report large gaps between simulation results and measurements, [21] [22] [23] [24] while other studies show that they can match very well.

Both conclude the factors mentioned above as the main uncertainties in BPS. Technological aspects[ edit building energy simulation Given the complexity of building energy and mass flows, it is generally not possible to find an analytical solutionso the simulation software employs other techniques, such as response function methods, or numerical methods in finite differences or finite volumeas an approximation.

In such programs, model equations are tightly connected to the solution methods, often by making the solution procedure part of the actual model equations. More flexibility offer simulation engines using symbolic Differential Algebraic Equations DAEs with general purpose solvers that increase model reuse, transparency and accuracy.

Since some of these engines have been developed for more than 20 years e. IDA ICE building energy simulation due to the key advantages of equation-based modeling, these simulation engines can be building energy simulation as state of the art technology.

Major use categories of building performance simulation include: Among whole-building simulation software tools, it is important to draw a distinction between the simulation engine, which dynamically solves equations rooted in thermodynamics and building scienceand the modeler application interface.

Most modeler applications support the user with a graphical user interface to make data input easier.

BEMP – Building Energy Modeling Professional Certification

The modeler creates an input building energy simulation for building energy simulation simulation engine to solve. The engine returns output data to the modeler application or another visualization tool which in turn presents the results to the user.

For some software packages, the calculation engine and the interface may be the same product. In layman's terms, the building is built from its component parts on a computer and a simulation is performed by taking that building through the weather conditions of an entire year.

In a way, building simulation is a way to quantitatively predict the future and thus has building energy simulation value. Building simulation is commonly divided into two categories: Load Design, and Energy-Analysis.

The common phrase for building simulation when energy is involved is Energy-modeling. Building energy simulation Design is used to determine: Predict the monthly energy consumption and bills Predict the annual energy cost Annual CO2 emmissions Compare and contrast different efficiency options Determine life cycle payback on various options Who benefits from Energy-modeling?
