Abstract: The construction industry regarded as one of the pivotal aspects of achieving the objectives of sustainable development in communities. In this regard, the choice of building materials is one of the challenges in order to improve program performance with respect to sustainable development, and the use of sustainable materials is an effective step towards achieving sustainable construction. Selection of sustainable building materials represents an important strategy in the design and construction of buildings in Ethiopia. One of the principal challenges is the process of prioritizing and aggregating relevant criteria into a selection framework. Therefore, the purpose of this framework in building projects is to look at the complexity of the interactions between sustainability building materials and architects and to set up a knowledge-based decision support system. After conducting a thorough literature review, case study (BREEAM, LEED, CASBEE, LBC, and G-SEED), questionnaire, and discussion with selected experts, 27 sustainable building material selection criteria items identified based on the sustainable triple bottom line. A survey of Ethiopian architectural firms was conducted to capture their awareness of sustainable building materials. A total of 199 registered offices, based on Ethiopia's construction ministry in 2021. From among these, 51 offices chosen, as a sample size randomly. One of the study's limitations is that it excludes other stakeholders, such as the client, who may have an influence on material selection. Another drawback is that since elements are used to organize materials and components, Ratings are thus based solely on product performance within each constituent group. On the other hand, this study excluded several items. For example, "products" such as lighting, water fixtures, HVAC, and electrical fixtures are not included.

Abstract: There are various frameworks for selecting sustainable building materials around the globe. However, it is difficult to get literature that describes their common characteristics, so the purpose of this paper is to try to provide a general framework for architects, and designers based on the literature review only. After conducting a thorough and systematic literature review, the number of observations for each data point shown as a percentage frequency distribution, which typically represented using tables. The process of creating a percentage frequency distribution entails first determining the total number of sustainable building material selection categories (such as economic, environmental, technical, social, and so on) to be represented, then identifying sustainable building material items (subcategories) within each category based on different authors' ideas to be represented. Finally, a general framework for sustainable building material selection developed. Finally, the proposed framework, which based on the sustainable triple bottom line concept, includes three dimensions: different authors frequently select economics (72%), environment (54%), and social (36%). Alternatively, it convert into a percentage of a hundred, it will be 44.50%, 33.3%, and 22.2%, respectively. As a result, we can conclude that when a designer selects a material, it is better to consider the three critical dimensions that are economic, environmental, and social factors.

Abstract: Under the background of the aging population, the concept of inclusive design was introduced to China in 2010. This paper describes a new method to assess the inclusiveness of outdoor seats by designing the inclusive evaluation tool table from document collection, desk research and analytic hierarchy process which can help to obtain the weight of each evaluation content. By the means of mapping the research and evaluation of 52 parks in Hangzhou in all dimensions, the paper draws a conclusion about the inclusive design of park seats. This research combines the qualitative research with data analysis thus to summarize the problems of inclusive design of the seat in urban park. The first problem is that the seat is damaged to varying degrees, especially from the surface and structure; the second problem is the lack of inclusive design, especially the lack of consideration of seat armrest and seat back; the third problem is lack of careful consideration in material selection; the fourth problem is the lack of accessibility. By analyzing the problem, it puts forward the inclusive optimization strategy for the four dimensions of the layout, function, shape and material of the park seats, in order to improve the humanized design of park seats as well as the inclusiveness of the urban environment.
