Abstract
The construction industry's main objective is the fabrication of a product that satisfies functional, security, durability, esthetic, economic and environmental requirements during its life cycle, in other words, a product that serves the intended function securely while also being durable, esthetically pleasing, economically viable and that translates into the smallest environmental impact possible. Sustainable construction is a way to responsibly create and manage a healthy constructed environment based upon the ecologic and resource efficiency principles, involving the consideration of a building?s life cycle. Generically, Life Cycle Cost - LCC, consists on the analysis of all the costs of a product, process or activity during its life cycle, with the purpose of optimization of its total costs. This dissertation analyses the life cycle costs of a façade, namely its construction, operation (energetic consumption cost) and maintenance costs (taking into consideration maintenance needs and service lives of the components). The case study is a residential building (integrated in project HEXA). Four façade solutions are developed, and their construction, operation and maintenance costs are determined. After that the solutions are compared. Finally, a sensitivity analysis of the results is performed. The conclusion is that LCC is a useful approach, although it needs further study and development, since it still presents a lot of problems.
