ECONOMIC AND FINANCIAL ANALYSIS DURING THE LIFE CYCLE OF BUILDINGS IN THE CONTEXT OF SUSTAINABLE DEVELOPMENT

Abstract

In the built environment, the sustainability assessment covers the stages of a building’s life cycle, namely: material production, construction, operation, maintenance, demolition and disposal. Taking into account the fact that in the current conditions, in a modern society, without no doubt, a long term perspective is needed, in these conditions the long term assessment takes into account all the stages that lead from raw materials, through production, distribution and use to the final disposal. Life cycle assessment (LCA) and life-cycle analysis (LCCA) instruments do not include the social dimension in sustainability assessment. Because of this limitation, the Social life cycle assessment (SLCA) method has recently emerged as a methodological approach aimed at assessing social aspects throughout the life cycle of a product. Generally speaking, Social Life Cycle Assessment (SLCA) provides a holistic, systemic and rigorous instrument for understanding the social problems that may arise in the value chains of products and services that support human life today. On the other hand, the Life Cycle Cost Analysis (LCCA) introduces an economic dimension to the assessment of material performance by calculating the discounted costs of ownership, operation, repairing/maintenance and disposal over the life cycle of the product.
