“…In this study, the thermal conductivity of the straw bales was measured by means of a heat flow meter NETZSCH HFM 436 Lambda. Figure 3 shows the operation scheme and a picture of the laboratory equipment [29]. The heat flow meter was placed in a conditioned laboratory at a temperature of 23 ± 2 °C and relative humidity of 50 ± 5%, according to the test conditions required by standard EN 12667:2001 [30].…”

This paper investigates the performance of timber-framed walls insulated with straw bales, and compares them with similar walls containing expanded polystyrene (EPS) instead of straw bales. First, thermal conductivity, initial water content, and density of the straw bales were experimentally measured in a laboratory set-up, and the dependence of the thermal conductivity of the dry material on temperature was described. Then, the two insulation solutions were compared by looking at their steady and periodic thermal transmittance, decrement factor, phase shift, internal areal heat capacity and surface mass. Finally, the acoustic performance of both wall typologies was analyzed by means of in situ measurements in two-story buildings built in Southern Italy. The weighted apparent sound reduction index for the partition wall between two houses and the weighted standardized level difference for the façades were assessed based on ISO Standard 16283. The results indicate that the dry straw bales have an average thermal conductivity of k = 0.0573 W/(m·K), and their density is around 80 kg/m3. In addition, straw bale walls have good steady thermal performance, but they still lack sufficient thermal inertia, as witnessed by the low phase shift and the high periodic thermal transmittance. Finally, according to the on-site measurements, the results underline that the acoustic performance of the straw bale walls is far better than the walls adopting traditional EPS insulation. Overall, the straw bales investigated are a promising natural and sustainable solution for thermal and sound insulation of buildings.

“…Secondly, recent industrial and academic research developed innovative building materials, characterized by high performances and-at the same time-reduced life-cycle impact [23]. For instance, some experimental research exploited the use of "unconventional" materials as cardboard, cork, or composite materials with vegetable fibers for building applications [24][25][26]. However, the examples are not consolidated in practices or available on the market, and their effectiveness as building materials has yet to be validated through long-term experimentation.…”

Smart Green Prefabrication: Sustainability Performances of Industrialized Building Technologies

2021

There is an urgent need to increase the environmental, economic, and social sustainability of buildings. Indeed, construction has one of the lowest rates of sustainability among productive sectors, associated with high energy demand and pollutant emissions, frequent cost increase and time delays, and poor and unsafe working conditions. Building prefabrication is a construction technique that can enhance the sustainability of buildings, in terms of predictability, product and process quality, and increased safety for workers. Recently, new approaches and concepts such as Industry 4.0 (Construction 4.0) and circularity of resources emerged in the field of prefabrication to potentiate the benefits of off-site construction. In this scenario, the scope of the work is to analyze the state of the art in the field of prefabricated building technologies in the light of these innovations and to evaluate their performances from a sustainability perspective. The work has been developed in two phases: (1) analysis of 13 case studies of prefabricated technologies in Europe; (2) comparative assessment of their sustainability performances according to 21 qualitative parameters. Based on the results of the work, a set of guidelines is proposed as the outcome, i.e., suggested strategies and approaches for designers and industry professionals that can be used to enhance the sustainability of prefabrication.

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.
