Thermally activated building systems in context of increasing building energy efficiency

Abstract

One of the possible ways to provide heating to the building is to use thermally activated building systems. This type of heating, besides providing significant increase in building energy efficiency, allows using low-temperature heating sources. In this paper, special attention is given to opaque part of the building façade with integrated thermally activated building systems. Due to fact that this type of system strongly depends on temperature of this construction-thermal element and type and thickness of other materials of the façade, influence of these parameters on energy efficiency was analyzed in this paper. Since the simplest and most promising way of using geothermal energy is to use it directly, for our analysis this source of energy was selected. Building energy needs for heating were obtained for real residential multi-family building in Serbia by using EnergyPlus software. The building with all necessary input for simulation was modeled in Google SketchUp with aid of Open Studio Plug-in. Obtained results were compared with measured heating energy consumption. The results show that thermally activated building systems represent good way to increase building energy efficiency and that applying certain temperatures within this element, low-energy house standard can be achieved.

A Review of Thermally Activated Building Systems (TABS) for Improving the Thermal Behavior of Buildings

“…The research on TABS embedded in building walls has shown that this technology can provide energy savings for heating by a factor ranging between 40 and 75% [39], [41], [42]. Several studies developed theoretical models validated with experimental.…”

“…To compare two TABS arrangements in a numerical study, Jiang et al, [36] obtained that the energy load reduction rate of a serial pipe-embedded wall (SPW) system is higher (25.2%) than that of a wall with embedded tubes connected in parallel (PPW) (8.7%). The influence of the TABS system on heating energy consumption in a typical Serbian home was determined by Stojanović et al, [39]. The authors simulated a TABS system in EnergyPlus.…”

Contribution to the Research and Development of Innovative Building Components with Embedded Energy-Active Elements

“…Variants with mechanical chillers show 30-50% higher electrical energy requirements for the production and distribution of cold, even though their running times are much shorter than the cooling towers' operating times. Stojanovic et al, (2014) [8]: The study focused on the possibilities of increasing the energy efficiency of buildings when using integrated thermally activated systems that use geothermal energy. It analyzed the effect of temperature, as well as the type and thickness of other materials of the nontransparent part of the building façade, on energy efficiency, as this type of element strongly depends on these parameters.…”

Estimation of Real Seasons in a Semi-Arid Region, Ghardaia, Case Study

“…Therefore, its choice is reduced to a single melting temperature in the comfort interval, between 17℃ and 30℃. Accordingly, a study has been carried out within this field in Ghardaï a region by Stojanovi et al [6]. These essential thermal problems related to buildings, caused many of the social hazards and social problems such as: the carbon monoxide emission (CO2) which causes environmental impacts: In Algeria; for example;…”

“…The number of people who died between 1 January and 09 February 2017, was 49 people, due to the carbon monoxide emitted by the different heating systems at the national scale [6], High heating and air conditioning bills, Greenhouse gas emissions (the increase in CO2 in the planet), thermal imbalance in housing, etc.…”
