Assessment model of energy performance in housing of Cuenca, Ecuador
(2019) Quesada Molina, Juan Felipe
Abstract This study investigates residential energy consumption in Cuenca, Ecuador, to develop a model to assess the energy performance of homes contextualized to the local reality. The research methodology is based on an analysis of international sustainability certification methods, case studies of the locality, and the participation of experts. The results determine an assessment model of energy performance composed of seven requirements with eleven evaluation criteria for multi-family dwellings, and six requirements with nine evaluation criteria for single-family homes. Three levels of compliance were defined for each evaluation criterion: standard, best, and superior practice. To meet the standard practice, for the use of such things as heating, cooling, lighting, equipment, and appliance indicators, energy usage must fall within a range of 30.1 kWh/m 2 per year to 41.6 kWh/m 2 per year; superior practice values must not be>24.3 kWh/m 2 per year.

There are different points of view and perspectives to analyze the theme of Heritage Conservation, each one of these must stand out as the principal axis, the primacy of the value in which the edification has been recognized as heritage. However, it is considered equally important the adaptation to the conditions of nowadays’ lifestyle, taking as a key point, the improvement of the indoor climate conditions. This topic had been focused superficially when it comes to the application in the patrimonial scope, with a limited number of studies in the Latin-American context, and without any studies in the local context. That is why this study comes to be important, it has as the main goal to demonstrate that it is possible to improve the environmental comfort conditions, without losing the characteristics that are part of the heritage value. To achieve this goal we have organized a work scheme where in first place we make an analysis of the current environmental conditions, both in the exterior and interior spaces, with the use of Data Logger equipment. With these results, we arise different solutions, which are applicable to the study cases according to their heritage value, an its validation through software tools of weather simulations. The obtained results accomplish the principal goal with great improve in the thermal and natural lighting points. Thereby, the importance of the study lays in the fact that it is possible to improve the quality of the indoor environment without losing the present heritage value.

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.
