“…The drystate values for plaster, hovering around 0.17 W/(m•K), are also debatable. Other sources [12][13][14] report values between 0.2 and 0.5 W/(m•K), for gypsum plasters with densities around 1000 kg/m 3 . The gypsum plaster in the discussed paper is 1367 kg/m 3 , and its thermal conductivity should therefore exceed the 0.2 to 0.5 W/(m•K) range.…”

“…Plant waste, like palm wood, has been used for the production of multi-layered wood panels by several searches [28,29]. Many innovative techniques use the different parts of the date palm mixed with different basic building materials to produce bio-based materials [31][32][33][34][35].…”

In this study, a passive solar house prototype was built using Trombe wall and was tested in the semi-arid region of Batna, in eastern Algeria. Traditional local materials (stone and adobe) were used for the construction of the thermal storage wall. A new local bio-based material made from date palm trunks was used for the insulation of the passive house prototype. For a better understanding of passive house heating and for a comparative study, a numerical simulation, using Fluent, was carried out. The aim of this study was to supply recommendations for improving the passive systems and to participate to the energy consumption control in the building sector. The results show that the experimental and numerical simulation results are in good agreement. The optimal orientation of the solar passive house has been determined, which is at 160° southeast. The use of local and bio-based materials has proven its effectiveness in the construction of the passive house. The thermal behavior of date palm wood has been found to be close to those of insulation materials commonly used in buildings. That means it has the same thermal insulation ability (thermal conductivity). On the other hand, the results show that the thermal efficiency of the passive solar heating system, with an adobe wall is significantly higher (50%) than that with a stone wall (30.7%).

Buildings account for more than 40% of EU final energy demand. Most of the existing buildings will be standing over 30 years time, when the new construction rate is still low. This means that the existing building refurbishment represents a key factor for the primary energy saving potential of EU, up to 2050. The heat exchange measurements in situ are so crucial for real dynamic behaviour characterization for standard and new solutions, such as the operative settings investigation due to user and external constrains. A new heat flux sensor development, called Tile, is exposed in this paper. The research started from the study of a commercial sensitive element based on semi-conductor materials. Its thermal and electrical properties were experimental investigated. An effective and dedicated frame was set up, aiming at accuracy and stability advantages in terms of its influence on the measured values. Some prototypes of Tile sensor were realized and checked.
