Several Aspects of Automation of Energy Supply Systems in Precast Concrete Buildings

ABSTRACT

The background of this article is formed by the results of studies carried out by authors in areas of design, construction and operation of smart buildings and installations.

It was found that the reasonably configured structure of a smart building provides acquisition of objective information about the condition of building utilities (including energy supply systems) and their operation, optimisation of utilities equipment control, making it possible to reduce total expenses and provide opportunities for making prompt decisions in case of onset of emergencies and their timely localisation.

The major components of a smart building are specified: elements responding on presence or absence (activity or inactivity) of smart building users and on variation of environment parameters; automatics tools regulating the parameters of a smart building in accordance with the results of analysis of environment condition and variations of environment parameters; smart building self-regulation algorithm focused on improvement of comfort and safety for its users.

The utilities are defined forming the unified information network: automated building control system; structured cabling system; cable conduit system and actuators; balanced energy supply system; air conditioning and ventilation system; automated water supply system; automated heat supply and energy saving system; local computer network; private automatic branch exchanges (PABX); community antenna television (CATV); automated lift equipment system; electric clock system; local broadcasting, warning and emergency evacuation system; building security system.

The studies carried out made it possible to specify the recommended list of utilities for buildings and installations for which the unified automated building control system application is reasonable; the major functions of these systems including the energy supply systems; major components of the automated building energy supply system, technical and process-related requirements for it; energy consumption groups in the building energy supply system, corresponding to their usage conditions; basic performance characteristics of components of the automated energy supply system described in the requirements specification (power consumption, operating mains voltage, heat release, electromagnetic compatibility of equipment etc.); specific features in automation of energy supply systems in precast concrete buildings; basic performance characteristics of peripheral data display devices providing generation of emergency alarm; requirements for arrangement of electric power supply for the devices within the unified automated building control system, taking into consideration the arrangement of the secure electric power supply system and installation of backup power supply units.

The gained results make it possible to design automated energy supply systems in precast concrete buildings in a most reasonable and cost-effective way.
