Economic and Technical Analysis of Renewable Resources and Natural Materials Through Advanced Technologies of Energy Performance Modernization

    Eugenia Trasca, Marin Bica

Abstract

ABSTRACT Buildings are the main energy consumers and implementation of renewable energy sources is a priority measure for decreasing the costs of energy and greenhouse gas emissions. The purpose of the work is to analyze renewable energy sources integration in constructions sector, for evaluating economic and technical environment, some system performance regarding decreasing energy consumes for buildings, economic benefits and greenhouse gas emissions, decreasing emissions. In this way we compared four types of buildings with different structures, from different climates. There have been used four types of technologies for analyze: a building that have integrated in the envelope a solar system for warming the air (SAHS); a building that has included a natural packet of walls formed by a layer of straws and natural innovative plasters; a building that has included a fluorescent lighting system and an incandescent one, window glazing and glass wool, roof isolation using cellulose and mounting photovoltaic systems; a building where walls are isolated with expanded polystyrene of 10 cm, windows replaced by double glazing, ventilation system installation, solar panels and photovoltaic. The techniques used consist in determination of heat loss through walls, and fossil resources dependence. The results demonstrated that using the solution packet fossil resources addiction is reduced by 15%, heat loss through walls is reduced obtaining a heat recovery bigger than 9%. Net economy, investment savings ratio, adjusted internal rate of return, global cost was determined. The whole analysis brings important contributions to the field by using in projection activity of envelope-installation renewable sources and natural materials through advanced technologies that brings significant energy savings at competitive prices. Keywords: energy efficiency in buildings, economy analysis, innovative insulating materials, renewable resources
