“…However, this method offers only a temporary solution, as the wood may degrade over time without consistent care and maintenance (Kuittinen et To optimally protect wooden structures from external environmental threats, i.e., biotic and abiotic factors, it is essential to incorporate an external protective layer (façade), preferably made of wood, and preferably reresistant. The rising demand for sustainable wooden materials, coupled with intensifying urbanisation due to population growth (Ott et al 2016), calls for the closer examination of wood in the context of re safety regulations. The challenge extends beyond leveraging wood to curb the incidence and spread of re; it also involves conserving resources while adhering to contemporary building codes (Österreichischen Instituts für Bautechnik 2019).…”

The aim of this work was to investigate the fire resistance of silver fir (Abies alba L.) and European ash (Fraxinus excelsior) boards charred by the traditional yakisugi method and to compare the results with the fire resistance of non-charred boards as a reference. After the boards were surface charred on one side, specimens with different char thicknesses were selected from each wood species and subjected to analysis. Specimens with dimensions of 250×90 mm underwent a small flame test, those of 220×170 mm received indirect flame exposure by constant heat flux radiation from an infra-red emitter and those of 600×600 mm were subjected to a fire resistance test according to EN 1363-1:2020. The results of the small flame tests showed significant fire-resistance enhancement of specimens with a 6 and 3 mm char-layer thickness in fir and ash wood, respectively, and a 110% and 75% improvement when compared to reference specimens. The constant heat flux radiation tests did not reveal any significant differences between the reference and charred specimens. The up-scaled fire resistance test, in which an assembled panel was exposed to flame, also indicated significant improvement. The reference burn-through time of fir and ash specimens was improved significantly with increasing char layer thickness, resulting in 10–26% of fire resistance improvement for fir and 5–12% for ash wood specimens. These results suggest that one-sided surface charring of wood can enhance its fire resistance; however, this was mostly achieved in boards with the thickest char layer in both wood species studied. Further in-depth studies are required to better understand the complex behaviour of charred wood in response to fire.

Dabei stehen anthropozentrische Positionen, die den Wert der Natur vor allem anhand ihrer Funktion für die menschliche Gesellschaft bestimmen, physiozentrischen Positionen gegenüber, die der Natur und ihren Lebewesen einen Eigenwert zuweisen und die hervorgehobene Stellung des Menschen als willkürlich und moralisch nicht haltbar kritisieren (vgl.…”

Nachhaltige Lebensführung

Soziologie Der Nachhaltigkeit

Vor dem Hintergrund der sozial-ökologischen Krisen der Gegenwart ist es von entscheidender Bedeutung, nachhaltigere Formen der Lebensführung zu realisieren. Auch wenn sich diese Einsicht in den letzten Jahren zunehmend verbreitet, bleibt weiterhin umstritten, wie dieses Ziel erreicht werden kann. Bildung und »aufgeklärter Konsum« allein werden nicht ausreichen, wie immer wieder deutlich wird. Aber welche Faktoren sind dann von Bedeutung und wie entsteht nachhaltige Lebensführung in der alltäglichen Praxis? Benjamin Görgen geht diesen Fragen nach und nimmt dazu die Realisierungsbedingungen nachhaltiger Lebensführung am Beispiel gemeinschaftlicher Wohnprojekte im urbanen Raum differenziert in den Blick.
