Die Fassade ist das Gesicht eines jeden Bauwerks. In der modernen Architektur findet die Holzfassade verstärkt Anwendung, um den Eindruck von Neubauten positiv zu verstärken. Im aktuellen Holzbau-Boom werden die Farbänderung und Wartung der Holzfassade bereits planerisch berücksichtigt. Wie steht es aber mit der nicht sichtbaren Alterung? Die Holzf...

Der Einfluss von Baumaterialien auf die Menge flüchtiger Substanzen in der Innenraumluft von Wohngebäuden und der Einfluss derselben auf die Bewohner dieser Gebäude stand im Blickpunkt zweier Projekte der Holzforschung Austria (HFA). Dabei wurden verschiedene Bauweisen (Vollholz-, Holzrahmen- und mineralische Bauweise) miteinander verglichen und de...
Conference Paper
Increased concentrations of VOC (volatile organic compounds) and low molecular weight carbonyl compounds (e. g. formaldehyde), but also other emissions, such as ammonia, occur in indoor air at residential properties at specific times during use and are mostly construction, material or situation specific.If the pure venting of these substances happe...

Seit Jahrzehnten ist Recycling, zumindest im Kontext der Mülltrennung, in unser aller Bewusstsein. Die Kreislaufwirtschaft zielt auf die effiziente Nutzung von heute immer wertvoller werdenden Rohstoffen sowie die Rückgewinnung von Ressourcen ab. Es gibt aber auch unerwünschte Nebenwirkungen: Problemstoffe, die über Verschleppungsmechanismen wieder...

The suitability of common analytical methods for the determination of active substances from wood preservatives in aged wood samples was investigated during an interlaboratory study. Permethrin, propiconazole and tebuconazole were quantified in 1.5 and 8 year-old wood samples by gas chromatography and liquid chromatography. Generally, the applied m...

Indoor air quality (IAQ) was investigated in 13 newly-built, occupied timber houses on a long-term basis. The study included a comparison of the construction types timber-frame (TF) and solid wood (SF), in addition two different ventilation types, controlled vs. window ventilation, were contrasted. The emission progression of volatile organic compo...
Presentation
Full-text available
Altered architecture and building physics constantly lead to changes in indoor air quality (IAQ). Whereas prevention of the sick building syndrome is covered by a variety of regulations, and the development of low or non-formaldehyde emitting wood products is promoted, things are different for VOC emissions (volatile organic compounds). Typical VOC...
Conference Paper

Emissions from products are widely discussed, but focusses on isolated products under controlled conditions. These measures help with material selection and product development, especially if designed for low emitting products. However, when forming consumer products such as furniture or even residential buildings, a variety of different products a...

Interior spaces and indoor air quality significantly affect our physical and mental well-being and comfort, especially in healthcare and living environments. The qualitative performance of buildings depends on several factors. Temperature and moisture are central characteristics of interior spaces and research suggests that these can be affected b...

This paper is divided into two parts: In the first part, the model room VOC measurement concept is evaluated with specimens from different construction materials in order to estimate the safety margins when using day 28 as the time point for indoor air quality assessment. Safety margins between 2 and 20 were estimated for softwood-based products. I...

This work presents a comprehensive overview on studies performed by Holzforschung Austria related to volatile and very volatile organic compound (VOC and VVOC) emissions from wood and wood products carried out in a full scale level. Scaling is crucial and due to material combinations additional sinks appear and sorption and diffusion of the monitor...

Fuel pellets are usually produced from raw materials with high lignocellulosic content like bio-mass from wood, straw etc. with a huge variety of the raw material quality grades. While high calorific value is the most desired end-product property, other product characteristics are also of interest. Gas emissions could be crucial for the subjective...

Emissionen von Holzpellets stellen eine Herausforderung für Produzenten, Händler und Anwender dar. Neben einer adäquaten technischen Lösung in Form von ausreichendem Luftwechsel in Lagerräumen, muss vor allem die Emissionsrate der Pellets selbst reduziert werden. Bislang nicht letztgültig geklärt ist der Entstehungsmechanismus von Kohlenmonoxid-Emi...

Dieser Projektteil befasste sich mit der Belastung der Innenraumluft mit (leicht- mittel und schwer-) flüchtigen organischen Verbindungen (VVOC, VOC, SVOC). Durch die luftdichte Bauweise von Containern besteht die Möglichkeit, dass sich Emissionen aus den verwendeten Baumaterialien sowie aus der jeweiligen Innenraumausstattung in der Raumluft anrei...

This paper reports on first results from a recently finished project dealing with indoor air quality in timber constructed houses. The FLEC method was applied measuring single building products with respect to their emission of VOCs (i.e. volatile organic compounds) on a small scale. Furthermore, total emissions are investigated in full scale model...

In this study 25 different building materials often used in timber constructions (wood based panels, gypsum boards, vapor barriers, adhesive tapes, insulation materials and sealants) were investigated with regard to their adsorption, desorption and diffusion behaviour towards volatile organic compounds (VOC). The materials were exposed to four, res...

Fenoxycarb ist ein insektizider Wirkstoff, der wegen seiner hormonähnlichen Wirkung in sehr geringen Konzentrationen in Holzschutzmitteln eingesetzt werden kann. Das hat zur Folge, dass aus Extrakten von behandeltem Holz relativ geringe Fenoxycarb-Mengen vor dem Hintergrund ebenfalls extrahierter Holzinhaltsstoffe zu bestimmen sind. In Vergleichsan...

Vergleichsanalysen zur Bestimmung von Permethrin aus Holz ergaben, dass sich sowohl Extraktion mit Methanol im Ultraschallverfahren als auch Soxhlet-Extraktion mit Ethylacetat gut eignen, um Permethrin aus behandeltem Holz zu lösen. Verschiedene andere Extraktionsverfahren führen zu Minderbefunden. Zur quantitativen Bestimmung von Permethrin können...

The project aimed to improve the quality of indoor air with scavenger-materials. These materials are able to adsorb chemical substances out of their surroundings and bind them. Several kinds of Scavengers, which should be easy to combine with building materials, were tested in regard to their adsorption properties. To define the properties needed for indoor-air-quality enhancement, measurements in actual residential buildings were essential and therefor also part of this project. The performance of the most promising Scavengers was then also tested in real living spaces. The project IASca ran under the lead of Holzforschung Austria in the Collective Research Programm of the Austrian Research Promotion Agency (FFG), was financially supported by the Fachverband der Holzindustrie Österreichs (FV) and was conducted in cooperation with the Austrian Institute for Healthy and Ecological Building (IBO).
