Intelligent Building Control System for EPBD Certification Support

Abstract

Building commissioning is a developing concept also in the Czech Republic. At present time only some aspects of building commissioning are implemented as a part of the facility management and energy auditing processes that are related to EPBD implementation. The project, presented in this paper, aims to find ways of energy-efficient operation of existing and designed energy- efficient buildings and is based on the fact that many buildings designed according to modern principles, in its operation does not behave as expected. The project is investigating and developing procedures to help change the current often intuitive approach to operate buildings in a systematic activity, taking into account energy conservation. Modern control systems of intelligent HVAC buildings could provide not only the information needed for the operational control of building, but also to detect faults and to evaluate the energy performance of the building. Under the IEA Annex 47 project, authors started to develop tools that support additional aspects of the commissioning process, including new control system for building energy services. The paper is focused on specification of new function of building control system, providing information for existing building EPBD certification. Results in terms of implementation of this function into existing building energy control system are discussed.
