Abstract

This study explores the acceptance of different wood coverages on building facades with the aim of optimization of materials, and in turn improving overall sustainability. It firstly develops the principal physical variables and evaluation criteria; then, test models are created using an orthogonal design experiment; finally, two evaluation methods are used to comprehensively test acceptance, based on a questionnaire and an eye-tracking study. The results show that: (1) The effects of the amount of wood coverage and the wood patterns are significant, whereas the effect of material combinations is insignificant. (2) The acceptance of building facades is at the highest level when the amount of wood coverage is 65%. (3) The amounts of wood coverage for facades in the range of 35% to 50% are effective when designing the facade of wood buildings, in order to implement the dual targets of saving wood and higher acceptance.

Highlights

In the context of global warming, the avoidance of building waste is of urgent concern [1]

(3) The amounts of wood coverage for facades in the range of 35% to 50% are effective when designing the facade of wood buildings, in order to implement the dual targets of saving wood and higher acceptance
These results showed that there was a higher preference for wood coverage on building facades than for indoor wood applications

Summary

Introduction

In the context of global warming, the avoidance of building waste is of urgent concern [1]. Wood itself is a sustainable and carbon-negative material, which is beneficial for improving people’s well-being [2,3,4,5,6]. In this context, wood is widely utilized in the material-intensive sectors of construction and furniture due to its green ecological and bio-friendly material advantages [7,8,9]. To reduce construction costs and make use of wood both intensively and efficiently, it is essential to study optimal wood consumption in combination with other materials to improve the sustainability of the built environment. The evaluation of the visual preference for wood has become a strong area of research [11,12]
