- ItemCovid-19 and city: Towards an integrated model of housing, microbiology, environment and urbanism(2021) Encinas Pino, Felipe; Soto Liebe, Katia; Aguirre Nuñez, Carlos;; González, Bernardo; Bustamante Gómez, Waldo; Schueftan, Alejandra; Ugalde, Juan; Blondel, Carlos; Truffello Robledo, Ricardo; Araya, Paz; Freed Huici, Carmen Marcela; CEDEUS (Chile)As of May 2020, the global health crisis caused by the SARS-CoV-2 virus moves its epicentre to Latin America, with cities showing high rates of poverty, segregation, and overcrowding. Current advances in microbiology make it possible to understand in depth the relationships between cities, COVID-19, and other microorganisms, but a conceptual framework to articulate them is lacking, especially in contexts where social determinants are so relevant. This article proposes an integrated approach to microbiology, housing, environment, and urbanism, based on a model of interactions and an empirical analysis applied to Santiago de Chile. It was possible to analyse how the propagation of COVID-19 in the city is enhanced by vulnerabilities of socio-spatial, residential and urban health, including an approach from the concept of energy poverty. At the same time, it was possible to verify how the variables associated with these vulnerabilities allowed to explain the incidence rate per 100 000 inhabitants through the different communes of Santiago de Chile. Among these, the level of housing overcrowding, the number of households with heads of household in precarious employment, and travel to the central business district stand out. Finally, the need for microbiological sampling to improve housing conditions, neighbourhoods, and cities propose a new research agenda for this Urban Microbiome" multidisciplinary team, contributing to overcoming the vulnerabilities identified in this research.

- ItemRetrofitting strategies for social housing buildings in different climate conditions.: The Corvi 1010-1020 block type in three Chilean cities(MDPI Open Access Journals, 2018) Bustamante Gómez, Waldo; Schmitt Rivera, Cristián; Bunster Milnes, Víctor Andrés; Martínez Torres, María Paula; Chateau Gannon, Francisco; CEDEUS (Chile)Currently, less than 2% of the residential building stock in Chile meets minimum of thermal performance conditions while the current approach to social housing development has proved incapable of ensuring appropriate living standards. Demolishing housing blocks to replace them with new buildings is economically inefficient, environmentally damaging and socially unacceptable, as these structures represent an opportunity to renovate and upgrade existing buildings without disrupting consolidated communities. This ongoing research focuses on renovating the CORVI 1010-1020 housing blocks, a building type that was massively built across the country between 1968 and 1978. Today it is possible to find more than 2,000 units of this type of building—with no significant design variations—throughout Chile, hence between latitudes 18°S and 53°S of extremely diverse climates. This paper analyses the impact of different energy retrofitting strategies in the thermal performance of these emblematic housing estates. Accordingly, building energy simulation is used to evaluate three scenarios, i.e., the original design without changes, a retrofitting proposal focused on meeting current thermal code requirements, and an expansion proposal aimed at increasing both thermal performance and life quality conditions. In order to assess the performance of these scenarios, the simulations focused on three cities with contrasting climatic conditions, i.e., hot-arid (Arica, 18°27'S), Mediterranean (Santiago, 33°27′S) and tundra (Punta Arenas, 53°08′S). Operational energy demand, accumulated hours of thermal discomfort, and payback time periods are considered for comparative analysis. Whereas the results evidence that the cost-effectiveness of the proposed alternatives increases in colder climatic conditions dependant on space heating; overall, this study demonstrates that the retrofitting of these social housing buildings can help achieving significant heating and cooling energy savings as well as improving indoor thermal comfort conditions.
- ItemREVIEW AND COMPARISON OF DIFFERENT TIMBER BUILDING PRODUCTS' EMBODIED EMISSIONS USING FREE DATABASES(World Conference on Timber Engineering, 2023) Victorero Castaño, Felipe Andrés; Mendez, Daniela; Bascuñan, Felipe; Bustamante Gómez, Waldo; CEDEUS (Chile)This paper aims to present a brief review of sources of information for studying the variability of embodied carbon emissions in structural wood products commonly used in construction. The review considered 13 primary sources, focused on EPDs and generic databases, and allowed the collection of data for the study of 140 products divided into Sawn lumber, Glulam, OSB, and Plywood. The information collected made it possible to identify factors such as the variability of density properties, wood species, the origin of the products, among others. In addition to analyzing the variations in the biogenic carbon of the different products studied. The results allow us to conclude that although the variability of wood products can be significant, like any product of natural origin, when they are studied within the framework of the analysis of the materials of a building, they can present a smaller fluctuation than other materials such as concrete. Moreover, this effect can be accentuated in wood products with greater density or have undergone processes that increase the mass of biogenic carbon per cubic meter in the final product.
