La iluminación natural como estrategia de diseño pasivo para mejorar el desempeño energético de la vivienda popular en Loja.

Abstract

Architecture influences on the use of natural resources, therefore, it has the responsibility to contribute on the reduction of the environmental impact produced by it. Approximately 50% of the global energy requirement is consumed by lighting, heating, and cooling of buildings; that is why the present study shows that through the efficient use of natural resources, such as solar light and framing according to the Passivhaus standard, it is possible to optimally illuminate the spaces trough modifications made in geometry and location of windows allowing to take advantage of the natural sources of energy. A methodological process is proposed in which housing will be evaluated, highlighting monitoring processes, numerical calculation, and simulation; the analysis carried out allows the development of architectural, construction and environmental strategies that enhance the energy performance that it possesses. The proposal is validated trough light, thermal and economic gains obtained by implementing natural lighting as a passive strategy to improve the thermal performance of the house.
