This proposed glazing system is employed for the renovated building or the low-energy house for the purpose of improving thermal efficiency and energy preservation. The first model aims to examine the influence of the distance between two glazing (also defined as the air space thickness) in the heat flux by simulation using the COMSOL Multiphysics programme. This step helps determine the critical or possible optimum thickness of the space filled with air in the glazing system. Next, the total heat losses of the three-dimensional glazing system were calculated regarding the changes in ambient temperature based on the actual data collected in Budapest, Hungary. Results showed that the heat flux on the internal side of the glazing system decreased as the air space thickness increased from 50 to 150 mm and was almost stable from 200 to 300 mm. Hence, the range of 200–300 mm could be a feasible distance for the window system manufacture. A half reduction of the total heat losses relating to the increase in the thickness of air space was also explored as the actual temperature changed over 4416 h in wintertime. Overall, the glazing system numerically modelled in the present work proved a contribution to a reduction in energy consumption in buildings. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

For samples, preparation glued-in loose tenons (Domino dowels) and dismountable connectors were used as connecting elements. The joints were made of European beech wood and a D3-grade PVAc adhesive was utilized for bonding. The effect of the joint type, the shoulders’ bonding, and the load application direction were investigated. The test results revealed that the withdrawal resistance of Domino dowel joints exhibited twice the strength compared to Domino connectors. Moreover, the presence of a bonded area on the shoulders did not significantly impact the strength of the joints. In the case of corner joints, the bending moment capacity in compression was notably influenced by the bond line on the shoulders, although such an effect was not significant in tension. Domino dowel joints provided a robust and reliable permanent connection between wooden elements, surpassing Domino connectors; however, in both cases, the strength values exceeded those of conventional dowels and cam lock connector joints.

This study investigated the potential and strengthening effects of developing composite panels from coconut materials (CM) and reed straw (RS) particles in the presence of methylene diphenyl diisocyanate (MDI). Five composite panels with 100:0, 60:40, 50:50, 40:60, and 0:100% proportions were produced. The nominal density was 600 kg/m3 and the dimensions were 400 × 400 × 8 mm3. The panels were produced by hot-pressing for a total of 10 min at a maximum pressure of 7.2 MPa and at 135 degrees, and then slowly cooled at room temperature. The following experiments were performed: mechanical, physical and morphological properties, thermal conductivity, FTIR (Fourier transform infrared spectroscopy), and EDX (Energy disruptive X-ray). The study gave the following results: the thermal conductivity of the coir and reed panels is competitive with the thermal insulation capacity of similar natural-based insulation materials, and is close to the values of other mineral and plastic-based insulation materials. The values of thermal conductivity coefficient ranged from 0.08 to 0.10 W/(mK). Only reeds (MDI_1) boards have better results than coconut materials. Among the mechanical properties, flexural strength and internal bonding strength increased proportionally with the increase in the amount of coconut. The Young's modulus reached its maximum in the case of a 50–50% coir-reed mixture. The best values of the panels are: 6.33 MPa for flexural strength, 1.83 GPa for Young's modulus and 0.36 MPa for internal bonding strength. The morphological recordings confirmed the proper mixing and binding of the lignocellulosic materials in the composite. FTIR tests proved the successful chemical interactions. The findings support the possibility of creating a promising, environmentally friendly building material. LA - English DB - MTMT ER -
