  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.

  According to a general rule definition, the intelligent space (iSpace) is defined as a location (or space) provided with electronic sensor networks that enable the considered environment with intelligent behaviors. As a result, the considered space will be able to perceive stimulus around them and to understand events that happen its near surrounding. Cyber-physical systems (CPSs) are building blocks in Industry 4.0 that links digital technology and the physical environment in an industrial context. They combine intelligent physical objects and systems on a high level of functions integration. This paper emphasizes the main idea that intelligent spaces may be also modeled as complex cyber-physical systems, as well. This approach has been developed by discussing the theoretical basis of both the iSpaces and CPSs, respectively unfolding a short comparison between their basic behaviors. As a concrete example, the CPS model of a given iSpace framework is presented and discussed widely in the paper. This model has been experimented by using a Field Programmable Gate Array (FPGA) processor-based ready-to-use development systems and software technologies that handles reconfigurable hardware technology. The implementation proves that the developed CPS model is well feasible and expresses in all the main behaviors and functions of iSpaces. It is also mentioned that the actual stage of the technological development terms and scientific areas related to iSpaces and CPSs overlaps. In fact, this is not surprising at all by considering nowadays evidence that iSpaces are widely present and shared components in modern manufactory processes that are an inherent part of Industry 4.0 vision and reality.
