- ItemAnálisis Técnico, Económico y Medioambiental de la Fabricación de Bloques de Hormigón con Polietileno Tereftalato Reciclado (PET)(2019) Valderrama Ulloa, Claudia AlejandraSe propone la reutilización de material plástico en reemplazo del agregado fino en la fabricación de bloques de hormigón. Se analiza el comportamiento técnico, económico y medioambiental de la propuesta, a través de ensayos mecánicos, comparación de precios del mercado y cálculo de huella carbono. Técnicamente se encontró que las probetas de hormigón con un 10% de reemplazo PET tienen propiedades mecánicas acorde con la normativa chilena para bloques no estructurales, lo que permitiría la construcción de muros no estructurales. El análisis económico muestra que este bloque es altamente competitivo en comparación a los productos presentes en el mercado chileno. Finalmente, el cálculo de la huella carbono en las diferentes etapas de su ciclo de vida presenta una disminución en la etapa de extracción de materias primas
- ItemBreakdown of the Use of Energy in Common Areas of Residential Buildings in Chile(2020) Valderrama Ulloa, Claudia AlejandraAbstract In the last 15 years the population of the Metropolitan Region has increased by 16.10%. Due to this greater densification, many people have had to live in residential buildings. By accepting this condition, residents have also accepted a monthly payment of common expenses. The reality shows that the latter are unpredictable prior to the operation of the building and once in operation their distribution and origin, allowing for the planning of resources, is not known. Based on the foregoing, we propose an energy calculation method to estimate the electricity and gas consumption of hot water for both domestic use and heating of the facilities present in the common areas of buildings. The method was applied in 2 residential buildings in Santiago with similar characteristics in order to compare the results obtained with the calculation method versus the actual consumption information. The results show that the most consumed basic services correspond to gas used for boilers at 67.5% and electricity at 29%. Regarding electricity, cold water pumps generated the highest energy consumption followed by lighting of parking areas. The percentage difference between the estimated monthly expenditure and the monthly expense charged for electricity was 11.50% and 9.19% for Building A and B, respectively. Moreover, in the case of gas, the difference was 21.10% for Building A and 17.09% for Building B.

- ItemEconomic and Technical Analysis of Universal Accessibility in Social and Private Housing in Chile(2020) Valderrama Ulloa, Claudia AlejandraAbstract According to studies of accessibility in Chile show that the country is aging, by 2050 the population of the third age will increase to more than double where, in addition, the third of that group will develop some type of disability, with the physical type prevailing. Under this problem, Chile has modified his regulatory building body (OGUC) in 2016 establishing new design standards in order to have homes with basic characteristics of accessibility universal. But these modifications are not retroactive in housing policy. Because of this, the present study analyzes the incorporation of accessibility standards into social and private housing that are already built. Technically, it discusses basic solutions to comply with the regulatory approaches and then analyze the economic impact of the solutions, along with the modifications of non-structural elements for regulatory compliance without changing the useful surface of the housing. Showing to achieve accessibility in an existing private home the cost can increase by 0.08 UF/m2 and for social housing by 0.05 UF/m2. The study shows that with a good projection of the evolution of the people who will inhabit the houses, in conjunction with decisions from the design stage, they can have affordable housing at a low cost preventing the owner have to make large investments for adapt his house to any situation of disability that may be present throughout life.
- ItemEconomic assessment of the construction waste of a highrise building: A case study(2019) Bravo Baeza, Jorge Esteban; Valderrama Ulloa, Claudia Alejandra; Ossio Castillo, Felipe AntonioThis article presents a study of economic assessment and classification of construction and demolition waste (CDW) in a high-rise building project located in the Metropolitan Region of Santiago, Chile Chile generates over five and half million tons of CDW per year and affect the environment in multiple ways. Likewise, the CDW are also a symptom of productivity problems. An adequate management of waste requires an assessment of it. However, there is limited literature related to the assessment of waste volumes and their economic impact (generation, transport and final disposal). It is found that the estimated waste generated per constructed area reached 0,186 m 3 /m 2 for this study case with a total cost of 188.234,44 US$ that corresponds to 1.19% of the project budget. Likewise, the costs per volume of waste was 75,47 US$/m 3 © 2019 Centro de Informacion Tecnologica.

- ItemThermal and Mechanical Analysis of Plywood Boards Thermally Enhanced with Phase Change Materials(2020) Valderrama Ulloa, Claudia AlejandraAbstract Adding Phase Change Materials (PCM) in construction elements and materials increase their thermal mass, which may reduce temperature variation of indoor environment and improve thermal comfort of occupants. The present paper aims to study the thermal and mechanical impacts of embedding microencapsulated PCM in the adhesive of plywood boards. Mechanical properties of samples are measured using a standardized bending test; thermal mass is estimated with a homemade experimental setup based on a heated bed and two thermocouples. Tests were carried out on three different samples: a reference sample without PCM, a second sample with adhesive containing 25% of PCM, and a third sample with 30% of PCM. The most relevant results from the study showed that the mechanical properties of plywood boards were not significantly affected by the PCM, and the thermal mass was improved up to 19% on a variation of 30°C.
