Due to the continuously increasing demand for more comfortable residential or commercial buildings in the last decades the researches in the so called “intelligent buildings” topic has emerged as one of the most challenging and high ranked engineering task. Consumers also require a higher level of security, supervision, and control of the b
...uildings according to a large scale of user needs. These expectations face building automation and supervising system developers with a challenging problem, difficult to approach with classical methods or strategies. Therefore, this paper is focused to outline novel facilities and solutions offered by the current level microelectronic technologies in building automation. In the first step of this endeavor the benefits and advantages of the reconfigurable hardware systems is highlighted and outlined. Then a concrete building automation and supervising system implementation in hardware reconfigurable technology is presented and detailed. The main unit of this system has been built upon a Genesys Virtex-5 FPGA-based development board, as a high speed, parallel, and distributed computing reconfigurable unit. The software modules for building supervising and monitoring purposes embed last generation MicroBlaze technology which allows fast and convenient implementation of sophisticated control algorithms. The result of the entire development is a powerful and versatile system representing a well suitable solution for the most sophisticated and demanding customer needs in building supervising and monitoring applications.
