CONTROL AND MONITORING OF INTELLIGENT BUILDINGS

This department deals with designing advanced algorithms for controlling energy systems of buil-dings, for effective use of renewable sources and for energy storage. A related area of interest is the moni-toring of buildings and construction elements using built-in sensor networks. Another area of activity of the research team is the development of electronics, especially sensors, for use in buildings.

Monitoring, analysis and controlling the production, consumption and accumulation of energy in buil-dings using centralized as well as local systems.

Adaptation of new approaches for the environment of intelligent buildings including their deployment.

Electronics for underground navigation of drilling rigs for underground ho-rizontal drilling are developed in the laboratory. This navigation is based on the principle of generating the magnetic field of known parameters and its recording using precise magnetic sensors.

The experimental site is dealing with tests of PV systems, development of new components and verification of innovative ways of controlling these systems (e.g. using the prediction of the output of sustainable sources and local consumption, innerday energy tariffs etc.). Tools for simulation as well as for real verification are used in the laboratory and also at customer sites and in pilot projects. Measuring and development can be carried out in the form of basic research, applied research or routine expert activities.

System for monitoring the mechanical straining of wooden structures is currently being developed in the laboratory. Measuring of proportio-nal reshaping of glued laminated beams using Bragg grating which is integrated into the beam as early as during its production is carried out. Electronics and software for processing the measured data are develo-ped in the laboratory. In case of overloading of some of the load-bearing components, an alarm is triggered.
