  This paper discusses the idea to change the way to approach intelligent buildings (IBs) development and implementation by taking into account the last evolutions in cyber-physical systems (CPSs). Therefore, the main goal is to extend IBs design engineering with the constraints of systems in a CPS context. As well known, smart buildings are increasingly complex as they integrate many scientific areas and research topics, as well as a large scale of last-generation technologies. At the same time, the Internet has deeply transformed the way to manage information and services, respectively how information is transmitted and computed in cyberspace. The quick management and information processing inside cyber layer challenges the interaction with the physical world in a sense to develop IBs as smart distributed systems or CPSs. In addition to this, the papers emphasize the original idea of developing reconfigurable hardware technology-based (RHT-based) CPS architectures for IBs implementation purposes. The benefits of the RHT application in a CPS context for IBs are widely discussed and analyzed. The unfolded theoretical background has been supported by an implementation example using last generation software technologies. These experiments evidence the advantages and versatility of this challenging implementation paradigm of the latest digital technology, applied for current-state IBs development.

  Global electricity demands are increasing at rapid pace. Energy supply, their usage and technologies involved need to be more economical, environment friendly and socially sustainable. Efforts are being done all over the globe to reduce this green house effect; and renewable energy technologies to combat climate changes, which require extensive changes to the current electricity generation and distribution systems. To meet this goal, it is required to optimize the grid operations and available resources to meet the ever increasing energy demands in an efficient, effective and environment sustainable way. So strong and huge interests on smart grid have increased extensively in recent years around the world. This scenario could be a promising reason for future research in this area. This next form of electricity grid will be able to manage various parts of power production from power plants to the customers. Renewable energy sources appear strongly in smart grid so in this paper the effect of this sources will be studied also electric vehicles have a great effect on smart grid infrastructure ,communication and control this paper will discuss this effect if it come from the electric vehicle mode or vehicle to grid mode.

  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 buildings 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.
