In this paper, the environmental impact of thermally activated floors is studied in order to define if this type of emission system is a sustainable technology. The environmental impact is estimated using life-cycle impact assessment, more specifically with the MMG-method. In the process of examining thermally activated floors, three sub-studies are carried out. Firstly, the environmental impact of the building materials in a storey floor are examined by layer. Secondly, different floor compositions, with or without integrated radiant heating or cooling, are assessed. Thirdly, an impact assessment for both material and energy use is made for three common scenarios, where a system with concrete core activation is compared to two conventional heating and cooling systems, in an office building.Download PhD here

On 18th November our partner, Dr. Eline Himpe (Ghent University), introduced and presented our project to the UK division of the BEIS/IEA Heat Pump Meeting.
It was positively-received and clear in explaining project, concept and future plans for hybridGEOTABS and our planned manual, webtool and Knowledge Centre.

Activating the thermal mass of a building by implementing Thermally Active Building Systems (TABS) assists in reducing energy use for thermal management of buildings by utilizing a low temperature heating and high temperature cooling approach. Coupling TABS with geothermal heat pumps that use low-grade energy source in addition to model-based predictive control (MPC) helps to further decrease energy use. Most equipment in hybrid GEOTABS buildings follow a modular structure that can be classified as low, medium and high temperature sources, and emission systems depending on the building type and needs. This work describes the main characteristics of the individual modules and interfaces of hybrid GEOTABS buildings, and provides examples of three types of buildings that use the hybrid GEOTABS approach. These buildings are an elementary school in the Czech Republic, an elderly care home in Belgium, and an office building in Luxembourg. Although these buildings are functionally different, the generic hybrid GEOTABS concept can be abstracted based on a detailed consideration of the interaction between energy transfer systems (e.g. geothermal heat exchangers, heat pumps, boilers) and emission systems (e.g. TABS, air handling units, radiators, domestic hot water). This work defines the generic concept, individual modules, and interfaces between related components of hybrid GEOTABS, enabling the specification of a design template with a “minimum” number of required operational parameters. Such a template can enable fast sizing of major system components, consistency between design-build offers, and facilitate effective integration of the Hybrid GEOTABS into new buildings.
