Impacto energético y emisiones de CO2 del edificio con soluciones alternativas de fachada

Abstract

This work uses a simplified life cycle analysis (LCA) methodology to explore the impact reduction potential in the design phase in terms of primary energy and greenhouse gas emissions for a given building using several façade solutions. This is achieved through a review of several design criteria (wall characteristics, insulation level, reposition rate and component durability) and their combinations, and analizing how they relate to the selected impacts for the production and use stages in the building life cycle. Results show that both emissions and energy embedded into the building materials or the building process are of great relevance and impact of emissions is comparable to those due to the use stage. This work concludes that, for a given building, a significant impact reduction on the selected impact indicators can be achieved by a careful selection of building solutions and durability strategies (through maintenance or refurbishment) in the design phase.
