The energy consumption in the building sector represents up to 40% of the total energy demand of industrialized countries. In Europe, EU Directives and national laws aim to reduce the energy demand of buildings. The most recent regulations do no longer focus only on the operational period, but give more attention to the embodied energy and to the possibility of recycling construction materials at its end of life.
The application of a Life Cycle Assessment (LCA) is necessary to certify the global environmental-impact and energy demand during the entire life span of a building. LCA takes into account raw material extraction, manufacturing, use, and end-of-life disposal and recycling.
This paper presents the results of a full life cycle assessment study for the typical structural systems of Romanian houses. All the life cycle stages are considered, including house construction, use and demolition after 50 years.
A typical detached house is considered for the specific conditions of two major cities: Bucharest (with high seismic demand) and Cluj (with low seismic demand). The two typical structural systems are analyzed: confined masonry walls and reinforced concrete frames with masonry infills. For each configuration, an inventory of the construction materials is made, covering the considered structural building elements.
The environmental impact of the structure of the building is assessed, and the effects of its location and structural type are discussed.
