Interior wood use: linking user perceptions to physical properties

Abstract

Focus groups were carried out in Austria, Finland, France, Norway, and Sweden to understand building professional’s and laypeople’s perceptions of building materials and well-being in indoor environments. Focus groups asked participants to share their opinions and experiences related to seven main topics: choosing interior materials, naturalness, naturalness for building materials, well-being in the indoor environment, wood materials, cleanabililty, and ethics and environment. The main objective of the focus groups was to explore how the use of wood is perceived in the interior environment and suggest opportunities for use of wood in the built environment. Participants’ responses can be linked to the physical properties of wood: density/hardness, grain, thermal conductivity, moisture content, chemical composition, color, and natural origin. Based on the discussion, these physical properties can be related more closely to the perception of wood as a natural material with respect to intended use, such as visual and tactile products. Based on the findings, it is also possible to alter product properties to enhance users’ experience of wood in the interior built environment. The results also indicate that the relevance and trustworthiness of the current schemes for documenting sustainable forestry practices, is questionable.
