The presented article describes a functional approach and methodology to managing the internal
environment of an intelligent building (or «smart building»), which implies the use and transfer between
the peripheral equipment and central engineering and (or) automated systems of unchangeable
states, the absence of side effects and uncertainty in the implementation of control actions and the construction
of a decentralized network of computations and decision making at the edge side based on
the so-called «Internet of things». The mathematical foundations of the organization of a distributed
computing environment for the realization of a functional approach are considered. Brief descriptions
of possible control scenarios in various modes of operation of engineering and automated systems of
intelligent buildings are described. A theoretical basis is provided for recommendations on changing
the paradigm of design and constructing a general centralized automated control system for an intelligent
building from the automation of engineering processes to the intellectualization of management
and the creation of an artificial intelligence system that implements a complete and autonomous cycle
of building management and exploitation. The paper would be of interest for designers, system architects,
software engineers and scientists, who work in the area of implementing of smart solutions on
various levels of automation.
