This study proposes and supports the application of 4 criteria for the sustainable management of drinking water inside the dwelling in the city of Cuenca, Ecuador. The criteria determined are: the control of water consumption, the control of leaks, the use of saving devices and water reuse systems. Three levels of assessment are defined for each criterion: standard, best practices and superior practices. For the development of the research, surveys are applied to the population that allow probing the existence and predisposition to incorporate drinking water saving practices in the homes, in addition measurements of water consumption by uses are made in 10 homes for a week, together the official information on the water consumption of the canton Cuenca facilitated by the municipal company of the city is processed, and several standards are analyzed: ISO, INEC and the Ecuadorian Technical Construction Standard, among others. Finally, it concludes with the determination of a percentage of water savings of up to 30%, which can be obtained the application of sustainable practices.
Estándares de sustentabilidad para viviendas patrimoniales del Centro Histórico de Cuenca-Ecuador
(2019) Quesada Molina, Juan Felipe
El estudio tiene por objetivo analizar los estándares de eficiencia energética y calidad del ambiente interior de las viviendas patrimoniales del Centro Histórico de Cuenca, considerando los siguientes factores consumo de energía, temperatura, calidad del aire interior, iluminación natural y confort acústico. La metodología empleada es mixta y de diseño longitudinal, involucrando variables cuantitativas y cualitativas para la evaluación de las mediciones ambientales, eléctricas, así como las percepciones de confort de los ocupantes de las viviendas. En una primera etapa se realiza una encuesta a 280 viviendas de Cuenca para determinar hábitos de consumo energético y condiciones del ambiente interior; en una segunda fase se ejecuta un monitoreo de las variables eléctricas y ambientales en tres viviendas de características patrimoniales, mediante el uso de sensores de medición, simulaciones y encuestas de percepción. Posteriormente se analizan y evalúan los resultados para compararlos con estándares de eficiencia energética y calidad del ambiente interior de normas nacionales e internacionales, determinando resultados que demuestran que los usuarios se adaptan a condiciones de confort diferentes a los establecidos por normas, tal es el caso de la temperatura, donde los usuarios, como respuesta al clima andino, admiten rangos inferiores a los estándares establecidos.

At present, Building Sustainable Assessment methods (BSA) have developed systems to measure and rate the level of compliance of buildings. However, many authors have identifed potential problems that could arise from a poor import of these assessments. The present method was the result of an investigation that proposes to observe and analyze a series of specifc performances of the dwelling and its parts, which allow to ensure the quality of the project and to certify the future performance of the dwelling based on appropriate sustainability indicators for the city of Cuenca. The methodological design of the research went through three stages of development: First, a new approach on sustainable building assessment is presented, which may be suitable for developing countries, based on an exhaustive review of the state of the art. Second stage, based on the study of the city’s housing stock, defnes criteria and indicators. Finally, weightings for each evaluation topic are defned by different experts in the area. The result of this research is an evaluation scheme composed of a hierarchical structure of 3 levels ranging from general to specifc: 8 categories, 38 requirements and 80 evaluation criteria that apply to single family and multifamily houses.
