Predictive control in buildings has undergone an intensive research in the past years. Model identification plays a central role in a predictive control approach. This paper presents a comprehensive study of modeling of a large multi-zone office building. Many of the common methods used for modeling of the buildings, such as a detailed modeling of the(More)
Predictive Control performance using grey-box and white box controller models" (2016). ABSTRACT Model Predictive Control (MPC) is a promising control method to reduce the energy use of buildings. Its commer-cialization is, however, hampered by the difficulty of obtaining a reliable controller model. This paper compares two approaches to obtain such(More)
In order to provide decision-making mechanism for application of model-based control of heating systems in buildings, a method has been proposed that assumes the energy balance calculation as the performance bound for the model-based controller. If the performance bound is significantly lower than the actual energy consumption, a more accurate estimate is(More)
The implicit model predictive control based on models identified by subspace identification methods was implemented and tested on a large university building. The control was improved by incorporating the weather prediction into the model. The performance of said controller was estimated in an experiment, wherein two almost identical building blocks were(More)
There are many large highway tunnels constructed all around the world. The operation of such tunnels has to meet several requirements, e.g. energy consumption optimization, minimal influence on the surrounding environment, lifetime conservation , minimal maintenance costs, portal protection from exhaust, etc. As the tunnel system is typically very complex(More)
A detailed simulation has been proposed and implemented for a complex road tunnel to be constructed in Prague, Czech Republic. The work brings new approach to functional and spatial decomposition of traffic, ventilation and exhaust tunnel subsystems allowing a simulation of dynamics. The discretization method provides a highly realistic and detailed(More)
