Control strategies, monitoring and management for the efficient behavior of Thermally Activated Building Systems (TABS)

Thermally Activated Building Systems (TABS) play an essential part in the thermal response of buildings, in terms of dynamic adaptation and energy storage, enabling the separation between thermal energy generation and use. TABS can operate with low temperature, allowing the efficient utilization of renewable energy. Their thermal capacity needs to be managed by a control system, shifting TABS operation to time periods when energy production is most efficient and cost-effective. In this paper, a review of the operation strategies adopted for TABS is provided, in their specific integration in an existing office building in Madrid (Spain). The present control strategies are part of an integrated process, including the design phase, commissioning of TABS, monitoring, and optimization during operation. The effort to take advantage of the energy potential of the original structure, in combination with constant follow-up and management, puts the building on track to achieve a LEED Platinum rating. In line with the standards pursued by the LEED Rating System, a systematic audit procedure is conducted, aiming at the optimization of TABS energy performance, with the identification of energy waste and execution of corrective operations for the improvement of thermal comfort for the occupants.
