Abstract

Historic urban spaces are emplacements that present a particular special interest due to their cultural value and their both urban and architectural pattern. The built environment of cities is composed of a number of variables – anthropic, spatial, morphological, environmental, social, constructive and atmospheric – and all of them must be part of a system that is capable of generating more comfortable and efficient environments. Currently, the work of expert professionals linked to the built environment implies an environmental challenge related to the buildings and their direct harmony with the natural environment; the development of comprehensive plans capable of administering, preserving and protecting historical-heritage constructions in areas susceptible to certain natural disasters; as well as the incorporation of sustainability criteria in urban planning instruments, which is one of the main objectives for regional and state public administrations. This research work intends to propose a comprehensive set of analytical methodologies focused on the morphology of urban blocks, the vitality of the neighbourhood and the functional service life state presented by heritage buildings in order to provide strategies for a proposal for urban regeneration in the case of Barrios Bajos of the city of Valdivia, in southern Chile. This study shows the implications of the proposed methodologies in order to verify their validity and empirically test the application of this type of proposal in one of the historic neighbourhoods of the city of Valdivia, used as a prototype of southern Chile.

Highlights

In emerging Latin American countries exists a lack of standardised urban planning, which is a problem increasingly being placed at the center of twenty-first century development agendas (UN Habitat, 2016)
Urban renewal can significantly contribute to sustainable urban development if it follows a sustainable path, since planning both sustainability and urban renewal implicates physical, social, economic and environmental aspects (Zheng et al, 2014)
Studies related to sustainable urban renewal encompass a wide range of topics, Zumelzu (2019) points out four perspectives from which sustainability could be implemented in the field of urban renewal studies: physical, social, economic and environmental

Summary

Introduction

In emerging Latin American countries exists a lack of standardised urban planning, which is a problem increasingly being placed at the center of twenty-first century development agendas (UN Habitat, 2016). In the Chilean context, Borsdorf and Hidalgo (2010) stated that the urban space has evolved from a compact form to one expanded in the territory and mainly fragmented, undergoing important changes in the last decades and even in historical areas of the cities (Zumelzu & BarrientosTrinanes, 2019) In this sense, cities’ historic neighbourhoods retain their countries’ identity, focused especially on cultural and historical heritage. The revitalization process of a historical heritage urban sector implies the integration of a complex set of Buissink (1985) defines urban renewal in the physical planning and housing policy field as “the complex of.
