Résumé

Globally, building sector consumes a large amount of energy both for construction and operation. Especially, heating, ventilation and air conditioning contribute for 40 – 50% of total building energy consumption. Thermally Activated Building System (TABS), which is an energy efficient alternative to conventional mechanical air conditioning, can reduce the energy consumption of building operation. TABS is a radiant cooling technology, which utilizes the thermal mass of the building to achieve thermal comfort of the indoor space. In TABS, chilled water circulates through the pipes, which are embedded in the building structure. Chilled water removes the heat from the indoor and provides a comfortable indoor to the occupants. In addition to TABS, use of appropriate building material can enhance the energy-saving potential of buildings not only by reducing the cooling/heating load but also by reducing the embodied energy of the building. A sustainable and eco-friendly building material, namely Glass Fibre Reinforced Gypsum (GFRG) can be integrated with the TABS. The combination of TABS and GFRG is named as Thermally Activated Glass Fibre Reinforced Gypsum (TAGFRG). The present study aims to analyze the impact of various design and operating parameters on the performance of TAGFRG roof. A TAGFRG roof has been designed by embedding water flowing copper pipes along with the provision of air gaps in the structure. A commercial CFD tool has been used to simulate the TAGFRG roof. The design and operating parameters analyzed are diameter, wall thickness and thermal conductivity of pipe, pipe spacing, and temperature and flow rate of supply water.
