Estándares de sustentabilidad para viviendas patrimoniales del Centro Histórico de Cuenca – Ecuador
(Universidad de Cuenca. Facultad de Arquitectura y Urbanismo, 2019-02-01) Espinoza Mosquera, José Luis; Calle Pesántez, Andrea Estefanía; Ortiz Fernández, Jessica Mariela
The aim of the study is to analyze the standards of energy efficiency and quality of the indoor environment of the heritage dwellings in the Historic Centre of Cuenca, considering the following factors: energy consumption, temperature, indoor air quality, natural lighting and acoustic comfort. The methodology used is mixed and of longitudinal design, involving quantitative and qualitative variables for the evaluation of environmental and electrical measurements, as well as the perceptions of comfort of the occupants of the houses. In a first stage, a survey is carried out to 280 houses in Cuenca to determine energy consumption habits and indoor environment conditions; in a second phase, a monitoring of electrical and environmental variables is carried out in three houses with patrimonial characteristics, through the use of measurement sensors, simulations and perception surveys. Subsequently, the results are analyzed and evaluated in order to compare them with energy efficiency and indoor environment quality standards of national and international standards, determining results that demonstrate that users adapt to comfort conditions different from those established by standards, such as temperature, where users, in response to the Andean climate, admit lower ranges than the established standards.
Evaluación del consumo energético en la fase de uso de la edificación residencial en Cuenca. Diseño de estrategias para un modelo de vivienda eficiente
(2016) Calle Bustamante, Andrea Estefanía; Ortiz Fernández, Jessica Mariela; Guillén Mena,Vanessa Fernanda
Energy assessment during the use phase of residential building in Cuenca will allow the development of strategies for more efficient models of housing, from the reduction of energy demand for heating by means of the envelope and the electrical consumption for lighting. On this basis, it is questionable whether it is possible to put forward a model of housing in Cuenca, which generate low energy consumption without affecting the conditions of habitability, since the current society needs to maintain adequate levels of comfort within the housing. For that purpose it is necessary to understand the current state of the residential sector by conducting surveys, monitoring, measurements and simulations in a sample of housing in the city, this way information is obtained for further measurement and evaluation. After the evaluation, according with criteria from international certification methods, a number of concerns were identified, for which strategies are developed and applied to a house from the analyzed sample. Such strategies are assessed, showing a substantial reduction in energy consumption and demand, which demonstrates the importance of application and validation of energy-saving strategies.
