“…The TABS systems can be integrated with solar energy systems. 12 Zhang et al 13 designed a combined system of the diffuse ceiling ventilation system and the TABS, aimed at ensuring the heating, cooling, and ventilation of an office all year round. They carried out experiments that measure the performance of the system in a full-scale air-conditioning room.…”

Main principle of the thermally active building system (TABS) which is a type of radiant heating system operating at low temperatures range as 30–50 ˚C is to bring the ambient temperature to the desired level by heating the building mass. TABS system is also a system that can heat at low temperatures such as underfloor heating systems, and both systems can be applied in multi-story buildings. Because these systems operate at low temperatures, they are compatible with both each other and with renewable energy sources. At the same time, heating and cooling at temperatures close to room temperature can also increase the coefficient of performance (COP) in these systems. In this study, a double-layered system which is a new concept was designed by using both underfloor heating and TABS on the same floor; and the thermal performance of the double-layered TABS system (DLTS) was examined using the FLUENT/ANSYS programs. In the calculations, different supply water temperatures (30, 35 and 40 °C) and the pipe positions on the vertical axis (0.001 m, 0.050 m, and 0.100 m) were considered. It can be obtained from the results that the efficiency of the heating systems can be increased by using the new DLTS proposed in this study.

“…However, TABS energy efficiency is based on availability of large surfaces, which allow for a significant heat flux even at low temperature gradient between the heating or cooling fluid and the indoor space [9]. This feature enables low temperature heating and high temperature cooling, which increases the potential for renewable energy use for cooling [10,11] and heating [12,13]. Other advantages of TABS are the quiet operation, the low draught risk, and their integration to building design.…”

Unter Autarkie in Gebäuden versteht man im Allgemeinen die Selbstversorgung mit elektrischer Energie und Wärme. Der Beitrag konzentriert sich allein auf die Wärmeversorgung und stellt eine Untersuchung vor, der frei verfügbare Daten über teilweise selbstversorgende Gebäude zugrunde liegen. Im Wesentlichen wird hier die Teilautarkie bzw. der Autarkiegrad der Selbstversorgung von Gebäuden mit Wärme betrachtet, da komplett selbstversorgende Gebäude bisher kaum realisiert wurden. Der Autarkiegrad bezieht sich dabei sowohl auf die Erzeugung von Wärmeenergie als auch auf deren Verbrauch in den Bilanzgrenzen des Gebäudes. Die Auswertung betrachtet die entscheidenden Größen wie den Wärmebedarf, die solare Wärmeproduktion in Form der Kollektorfläche der Solarpanels und den maximalen Energieinhalt von Warmwasserspeichern. Damit ein Vergleich unabhängig von der Gebäudegröße gemacht werden kann, werden aus diesen Daten Relationen (Autarky Performance Indicators) gebildet und zum Autarkiegrad in Beziehung gesetzt. Dabei werden Tendenzen bezüglich der Kollektorflächen und den Speicherinhalten im Verlauf der Trendlinien des Autarkiegrades sichtbar.
