Which factors influence consumers’ selection of wood as a building material for houses?

Abstract

Construction and use of buildings is one of the highest users of global energy (34%) and one of the highest contributors to greenhouse gas emissions (37%). Using wood instead of carbon-intensive materials such as bricks reduces a building's embodied energy and is a more eco-friendly alternative. Since the quota of newly built wooden houses in Germany is still relatively low, gaining insights into the perspective of consumers is crucial. This study aims to investigate factors from a consumer perspective that influence the selection of wood as the primary building material for residential houses. Therefore, an online survey was conducted in Germany to gather data from individuals ( N = 510) who either bought or built a house in the last 5 years. By conducting a logistic regression, we have identified six influencing factors for the selection of wood. Positive views on wood's eco-friendliness and emphasis on renewable materials are key factors in choosing wood. Higher age and living in rural areas also increase the likelihood of selecting wood, while concerns about value stability and durability have negative effects. We conclude that increasing information activities, raising awareness about wood's ecological benefits, and dispelling prejudices can significantly impact its selection as a preferred building material.
