An Index for Evaluation for Urban Bicycle Lanes
Authors: Pesshana G , Romanel C , Novo J 
Published: June 2020

Abstract
Traditionally, the focus of urban transportation design is on motorized vehicles with less attention to green travel alternatives such as cycling. Public policy makers are now trying to increase cycling as a sustainable travel mode due to increasing concerns with respect to environmental pollution, traffic jams and health problems from today’s sedentary way of life. In the city of Rio de Janeiro, Brazil, the first bicycle lanes were built in 1991along the urban seafront for leisure and touristic purposes almost exclusively, but today the city counts on a cycling network of more than 150 kilometres under different conditions of conservation and use by the population. The manner in which this network is designed, built and managed can have a significant effect on the utility and safety of cycling. The primary objective of the current study is to develop a methodology and to propose an evaluation index that could be used as a practical instrument by municipal authorities, transportation planners, traffic engineers and others to determine the quality of bicycle lanes under 14 criteria based on social, technical and environmental aspects. The availability of a such comprehensive index is believed to be a key factor guiding cycle-friendly politics to build more sustainable cities
Living and Comfort Conditions in Heritage Housing: The Inner Courtyard as a Uniting Element in the Cités of Santiago Poniente
Authors: Piedra K , Bustamante W , Schmitt C 
Published: June 2020

Abstract
Heritage buildings represent an essential housing stock that has been available in Santiago de Chile for over a century. However, most of these buildings show sustained deterioration due to lack of maintenance, which creates degrading living conditions for its residents caused by habitability problems. One of these cases is the “cité” typology, which was massively built at the end of the 19th century. The Cité is a group of houses with a continuous facade, with built areas of 50 to 80 m2, connected through a common and private space that provides access to the residences. Currently, the reduced housing area in the city has forced users to occupy the existing courtyards to satisfy their needs. This situation affects interior lighting conditions, thermal control, and air quality. These interventions modify the architectural design into units with only one facade exposed to the exterior environment. Nevertheless, adaptation strategies have become more and more complex due to restrictions on heritage building regulations, which generally do not meet thermal performance or natural light availability. Among the environmental conditions, indoor air quality is a relevant factor and could be related to the progressive deterioration of the residence’s interior conditions, and the health of its residents.The methodology considers data compilation on existing units and energy performance simulations of both original and existing units. Software such as DesignBuilder and a wind tunnel were used to simulate different habitability variables. Results confirm that in the majority of cases studied, indoor air quality is not bad due to air infiltrations as a product of modifications, spontaneous extensions, and building deterioration through the years. However, they show an inadequate thermal performance that does not meet the minimal comfort conditions. Nevertheless, the simulations on original units demonstrate a positive impact of courtyards for reaching ventilation and natural lighting standards. Measurements on-site have shown a beneficial effect from using vegetation in ventilated covered courtyards.
Heating and Cooling Energy Savings of a Proposed Variable Thermal Resistance Envelope (Dynamic EIFS) in Office Buildings
Authors: Palacios I , Bobadilla A 
Published: June 2020

Abstract
This paper evaluates potential heating and cooling energy savings of a theoretical building envelope system capable of modifying its thermal resistance according to the changing weather conditions. A Dynamic External Insulation Finishing System (D-EIFS) theoretical model is proposed based on recent research on dynamic building envelope technologies, which suggest that this functionality will be fully available in the near future. We also develop and apply a unique simulation technique for using commercially available BPS software to assess the heating and cooling energy savings potential of a D-EIFS for office buildings. A performance comparison of the proposed D-EIFS with the most efficient EIFS for the same office building shows a heating and cooling energy savings of up to 26% in the summer season in a temperate climate.
Study of Social Organization for the Use of Firewood Heating in Zones Where Polluting Material is Generated in the City of Temuco, Araucanía Region, Chile
Authors: Alvarez E 
Published: June 2020

Abstract
Temuco, capital of the Araucanía Region of Chile, presents the highest indices of pollution by smoke from wood-burning heating stoves in the country, specifically during the southern winter. Firewood combustion is the cheapest heating fuel available to the population of Temuco, and has resulted in considerable contamination in the city. There has been an large increase in the city’s population, while the winter months from April to September have been growing colder. The problem affects the whole population, and especially children and the elderly. The pollution indices present serious levels. The evening and night are the worst times to be outside, due to both poor visibility and the toxicity of the environment. This situation is a social problem which has not been fully investigated. More seriously still, the people of Temuco do not display particular concern about their collective health or about protecting the environment from the smoke produced by wood-burning stoves. In view of this serious problem, the present article proposes a strategic design for information and social organisation by sectors in the city’s residential districts, in order to generate awareness and communication in the community. The strategic guidelines are drawn with special emphasis on visual communication, in both printed and digital format, in order to organise social groups of people motivated to solve the pollution problem. The central object of this proposal is to offer a strategic model able to generate collective awareness to support and help the city’s housing estates and residential zones. Connection between community members, empathy and social assistance will be basic aspects for the functioning of the strategy when it is applied. Finally the proposal contemplates social organisation in pursuit of the common good: protecting the local environment, improving people’s quality of life, and promoting social coexistence in housing estates and communities affected by the problem of pollution by smoke from wood-burning stoves.
Alberto Curamil and the Goldman Prize: Discussion of Cultural Sustainability in the Region of La Araucanía
Authors: Leal F , Navarrete C 
Published: June 2020

Abstract
The following article discusses the recent winner of the Goldman prize, Mapuche leader Alberto Curamil, as a case in the struggle for cultural sustainability in the Region of La Araucanía, mainly in his role as an activist in the defense of Mapuche territory and culture. This important international environmental award was conferred on Curamil for uniting Chileans in preventing the construction of two hydroelectric projects and protecting a river sacred to the Mapuche people, overcoming violent persecution and attacks against him in this activity. This makes it possible to problematize different aspects of cultural sustainability that are key in the region, in particular the issue that arises between the progress of industry and the ancestrality of indigenous peoples. Thus, it is interesting to discuss from this case how these two views can be harmonized in order to achieve cultural sustainability, bearing in mind the intercultural nature of the IX Region. Finally, this communication seeks to analyze the role of the Chilean State and its actions concerning the practices of cultural sustainability like those led by Curamil.
Universal Accessibility in UC Temuco
Authors: Simian M P 
Published: June 2020

Abstract
In present-day societies, people’s life expectancy is increasing thanks to medical and technological progress; therefore, the number of disable citizens is also increasing. An accessible design is one that is functionally and aesthetically adapted to its users and their real and personalized needs. Accessible spaces are those that allow everyone, particularly people with limited physical or sensorial capacity, to enjoy all its elements in the appropriate conditions of comfort, safety and autonomy. By incorporating this characteristic into the design of our products, buildings and into everything that surrounds us, we improve the comfort and quality of the articles and services we offer the public without increasing their cost, all thanks to small details that benefit the largest number of people. Each country has its own legislation regarding accessibility. In Chile the first Integration Social Law N°19.284 is due to 1994. One of the biggest difficulties for disable persons to move around cities and buildings is the lack of ramps in public buildings. Although the Supreme Decree 201/98 establishes that all building, public or private, with occupation for more than 50 people should have an access for disabled, although there are many places in this country that today do not validate this requirement. In the year 2010 the Law 20.422 improved the standards regulating the minimal general guidelines based on the accessibility requirements for improving especially bathrooms, hygiene services for public-use buildings and changing rooms. This document presents a local case of study. The Catholic University of Temuco (12.000 students) is located in the south of Chile (Araucania Region). This region is the poorest in the country. Since 2012 the University is part of the University Inclusion Network. Consequently, since then, educational buildings and public spaces have been improving accessibility and are now better prepared for the challenge of welcoming disabled students.

Mortar Based on Biomass Ashes from Araucanía Region
Authors: Soto O , Goméz N , Manzur C , González A 
Published: June 2020

Abstract
The COMASA S.A. power plant is located near Temuco and burns a high amount of residual biomass produced in the Araucanía region. However, the main problem associated with this plant is the transportation and disposal of fly ash (9 tons per week), a residue generated during the combustion of Boiler I. Currently, fly ashes from Boiler I are transported more than 200 km south, increasing transportation and final disposal costs. In this study, the development of a mortar based on fly ash from the combustion of biomass from COMASA S.A. was analysed at a pre-feasibility level. The experimental procedure consisted of (i) the physicochemical characterization of biomass fly ash, (ii) obtaining different test specimens (mortars) via the addition of different proportions of fly ash (10-35%) to cement, and (iii) obtaining the best specimen by analysing the requirements of mortars for construction purposes (Chilean Standard NCh 1037). The test specimens were subjected to determination of apparent density, compression resistance, water absorption capacity and moisture content. The laboratory results showed that the mortar obtained with the addition of 20% of fly ash has similar physical characteristics to mortars used for building blocks, proving capable of resisting up to 20 MPa. To analyse the viability of the production of construction blocks based on best specimen, market, technical and economic-financial studies were carried out, considering the reuse of at least 60% of the fly ash generated per year. The study concluded that the project was viable, evidencing the potential use of this residue for the manufacture of low-cost blocks, while minimizing the cost associated with residue handling.
Increase of Mechanical and Thermic Performance of Polymers with Renewable-Base Nanomaterials to Develop Composite for Fiber Reinforced Polymers Industry
Authors: Hunter R , Valenzuela P , Hidalgo P 
Published: June 2020

Abstract
The objective of this research was to evaluate mechanical and thermal performance of a commercial adhesive with the incorporation of renewable-based nanomaterials. Renewable-based CNTs (carbon nanotubes) were synthesized using microwave irradiation of pyrolyzed oat hulls biochar and ferrocene as catalyst. CNTs were mixed with epoxy adhesive and TEPA (tetraethylene pentamine) which were used as curing agents. In the evaluation of mechanical and thermal properties of the composites studied, the samples contained between 0.02-0.1 wt% of CNTs. All composites were cured during 2 hours at 60°C. Mechanical properties (tensile strength and modulus) were tested in a Universal Testing Machine and were evaluated according to ASTM D638. Thermal properties were evaluated using a Thermogravimetric Analyzer. Of the results obtained an improvement of mechanical and thermal properties were observed. Thus, the incorporation of renewable-based CNTs can be a suitable alternative both to reduce fiber reinforced polymer manufacturing costs and in the valorisation of waste biomass
Determination of Dwelling Typologies in Chile to Define Energy Efficiency Programmes
Authors: Galbiati J , Sepúlveda H , Videla J.T. , Hermosilla P 
Published: June 2020

Abstract
The Ministry of Housing and Urbanism of Chile (MINVU) has led the implementation of thermal conditioning requirements in dwellings (2000, 2007) as well as the Dwellings Energy Rating System (2012). To design improvements to both programmes, MINVU required a statistical analysis identifying the statistical distribution of the different parameters that influence the energy demand of the dwellings, as well as typologies and their distribution, both at the national level as well as that of the 9 thermal zones. A series of statistical analyses was developed for this purpose; mainly a Conglomerates Analysis, using specifically the hierarchic agglomerative method. This method was applied to detached dwellings, Semi-detached or Terraced dwellings and Apartment segments. So as to obtain more stable frequencies, as well as estimate standard deviations and confidence intervals, 200 random samples were obtained for each segment. The main result was the definition of 13 dwelling typologies in Chile, their respective distribution at the national and thermal zones levels, as well as the representation of the parameters that compose these typologies and influence energy demands. Finally, an analysis was carried out, based on secondary images of dwellings representing their respective typologies; this allowed complementing and correcting the typologies’ definition where it should be necessary. A second study is being carried out at the time of closing this document -using those results- this shall allow to establish the energy demand of dwellings built in Chile before 2018, by typology, thermal zone and thermal regulations stage, so that Minvu may quantitatively define the energy demand baseline, consolidate measurement metrics, and refine long-term improvement objectives.
Experimental Comparison of Passive Heating/Cooling Space in Lightweight Buildings with Potential Application in Mining Camps

Published: June 2020

Abstract
The total energy consumption in a house in Chile includes 30% of heating expenses, increasing to 60% in the winter period. The current energy source are fossil fuels, which can be replaced by the sun, with an efficient implementation of the use of PCM for passive cooling/heating space from solar radiation, benefiting the environment. In the north of Chile there is a solar radiation index of approximately 2750 kWh·m−2, low cloudiness and low precipitation rates, indicating an important source of energy and great opportunity for improvement in the use and management of energy resources. Moreover, mining camps present in large numbers in the northern zone require a lot of energy to cool and heat the space. This research shows the thermal behavior in summer and winter of two lightweight constructions, similar to the type used in mining camps, with dimensions of 2.5 × 2.5 × 2.5 m at pilot scale installed at the University of Antofagasta, Chile. One of these modules contains PCM on the inside of the walls and ceiling, while the other does not, to analyze the effect of PCM by comparison. The results of this work show that in winter (August) the application of PCM favors the permanence within the thermal comfort zone, with a difference of 5°C. In summer there is an opposite effect (January), experiencing a higher temperature increase inside the container with PCM, with a difference of 4°C. According to the constructive characteristics, properties and quantity of PCM used, and the effect of solar radiation on the structure and environmental conditions, there are benefits in energy saving and efficiency in the winter period, while summer shows results that enhance the study and analysis of the applied technology to solve the thermal behavior shown in this season.
Alfândega Square: The Place of Plurality
Authors: Volpatto C P , Edelweiss R K 
Published: June 2020

Abstract
The present article is based upon a master’s degree Dissertation entitled “Alfândega Square: a place of places”. Subject to the current work is the Alfândega square, located in the historic portion of downtown Porto Alegre, the capital of the Federal State Rio Grande do Sul. The square is composed by distinct parts: Lugar de Memória (the place of memories), Lugar de Entorno (the place of ambience), Lugar de Pluralidade (the place of plurality) and Lugar de Evento (the place of events). With these different places highlighting the various dimensions of public places in metropolises, using the Alfândega square as the study subject raises some relevant questions about how much a public space can change throughout its existence. It can be affirmed that in this mosaic of social representations, vicinal territories and symbols comprise an important locus for the analysis of the urban space, since it presents itself for social forms’ multiple spaces of material survival and social coexistence. For this reason, the study of the Alfândega square is also an investigation about contemporary urban phenomena and their multiple and emerging social practices that are modified by the influence of external factors in the city. This article has its emphasis on the place of plurality, remembering the profile of regular visitors in the past and comparing it with present-day users. The non-participating observation methodology was used to analyse regular visitors of this public space. Visits to the square where carried out in different periods of time during the two years of study. As a result of these visits, a series of territorial maps were created, depicting the territories of the regular to the square.
Social Perception of Living Walls in Quito: A Study of Four Vertical Gardens
Authors: Maron A , Ramirez F 
Published: June 2020

Abstract
As part of a transdisciplinary study on the benefits of vertical gardens in Quito (Ecuador), social research was carried out to determine people’s perceptions and level of understanding of living walls. The four gardens studied were on the campus of the Pontifical Catholic University of Ecuador (semi-public), in the San Blas Plaza (public), in the Governmental Financial Platform (semi-public), and in the private offices of an architecture firm (private). The research was organized into two primary phases; the first involved carrying out observations of each of the four vertical gardens. The observations led to the characterization of the immediate surroundings of the gardens, an understanding of accessibility (particularly for people with disabilities and security-related limitations), as well as of the number of people who passed through the space and the type of interactions they had with the garden. During the second phase, a total of 57 interviews were carried out with people in the areas surrounding each of the vertical gardens. The interviews identified basic demographic information about the respondents, how they define vertical gardens, the type, and frequency of their interactions with the specific garden of study, and their perceptions of the benefits and drawbacks of vertical gardens. The information from the interviews was processed to identify key trends related to each garden, as well as identify trends across the four gardens. The results revealed varying levels of understanding of vertical gardens, the influence of esthetics on people’s perceptions, and finally ideas around the benefits and drawbacks of vertical gardens. The conclusions demonstrated a gap between social perceptions of vertical gardens, particularly in public spaces, and the gardens’ potential ecological and air quality contributions to the city.
