The starting point of this research is the urban model promoted by the United Nations through the Sustainable Development Goals(SDGs).The importance of public spaces is especially highlighted in Goal 11.7:“provide universal access to safe,inclusive,and accessible,green,and public spaces.”The quality of public spaces can be properly assessed by reconsidering the quality indicators and investigating their development potential,which is the main focus of our research.This study is based on a theoretical and methodological reflection on the quality of public space,considering the contributions of some contemporary urban traditions and a few recent experiences.From this perspective,a variety of public space projects developed in the European sphere have been selected and analyzed.The quality parameters identified in this initial analysis were then applied to the analysis of nine representative case studies in three Spanish cities(Madrid,Barcelona,and Zaragoza).The main goal is to propose a methodology that helps to evaluate the quality of those public spaces and determine its relationship with the safety,accessibility,and inclusiveness conditions they offer. 展开更多

The conception drawing in architecture is that allows to initiate the architectural thinking,visualizing,and discovering the first ideas.This drawing has traditionally been given as an act of linking and collaboration between thought,sight,and the movement of the hands with a tool.Identifying and recognizing its characteristics will make it possible to deal with any mediation of information technologies.To establish such characteristics,three case studies were carried out.An analysis was made of the conception drawings and interviews by the Pritzker Prize laureates:Ando,Hadid and Gehry.One condition and four characteristics have been determined:drawing is a phenomenological action that produces haptic drawings;it is an undecided process that originates unformed drawings;it is a fast action that results in small and multiplied drawings;it is a perceptual act that generates redrawn and remarked drawings;and finally,it is an action that seeks to remember to resume the creative process at another moment,which produces rudimentary conventional drawings.Knowing these before any technological mediation will be an important pedagogical contribution that will allow future architects not to alter the cognitive processes that generate the first ideas in the initial moments of the architectural project. 展开更多
