Research on design evaluation of wooden outdoor seating system

Abstract

[Objective] Although there are many kinds of materials for outdoor seating, there are also limitations. People prefer natural wood materials which are warm in winter and cool in summer. From the perspective of sustainable development, wood substitute for natural preservative wood is replaceable, so it has become the main material for outdoor seating. The purpose of this paper is to verify the advantages of wood and wood -like materials in the application of outdoor seating with expert evaluation methods. [Methods] The Del phi expert evaluation method was used to optimize the different schemes of wood and non -wood materials in the empirical study. Based on the three levels of “environment - space - people ”, the evaluation was carried out from multiple perspectives, from the urban ecological environment appeals of the top system of the macro root layer to the extension system of the meso-generative layer of the harmonious space and place system, as well as the micro-representational layer ontology system problems involving the form, function and material technology of outdoor seating. [Result] Finally, based on the quantitative data analysis of Delphi expert evaluation method and standard deviation comparison analysis results, the outdoor seating system design of wood and imitation wood materials was obtained by experts’ preference and affirmation. [Conclusion] T he material selection of outdoor seating can be mainly wood, and the acceptance of imitation wood outdoor seating is similar to wood. When selecting outdoor seating materials, we can gradually introduce composite anticorrosive wood materials to replace non -renewable natural anticorrosive wood.
