Estudio de factibilidad económica y financiera utilizando tecnología Net Zero Energy para la construcción de un proyecto de vivienda familiar urbana de clase media en la ciudad de Quito

Abstract

This thesis aims to determine the economic and financial feasibility of implementation in buildings of a self-sustaining power system. Arises the need to propose alternatives for clean energy generation because the weather patterns on the planet earth are changing because of emissions of carbon dioxide into the atmosphere, this leads to an awareness of change in the population towards decreasing consumption of natural resources. This is why it is handled worldwide the concept of Net Zero Energy, which means that a building must produce by renewable resources in a year the equal amount of energy consumed by itself. This concept among other parameters such as good use of building materials, proper architectural design, saving elements in electrical and water systems and waste separation, form a sustainable construction. The lack of policies in Ecuador related to sustainable construction has slowed the development of projects proposed under this concept, as the high subsidies that the state implements in the energy generation with natural resources. The generation of clean energy with a photovoltaic system arises using the sun as a source which is free and unlimited, however the high cost of these systems is mainly due to the use of batteries to storage energy, and this is because there is no possibility to connect to the public network managing a buy-sale of energy that allows the financial and economically project feasibility, because under current conditions it is not.
