Abstract

Abstract: The construction of new buildings as well as its retrofitting processes should be ruled by sustainability concepts considered since the design and project phases. The materials and the construction processes used at each stage have a direct influence on the sustainability of the final solution at all parts of the "before use" stage of a building life cycle, namely: "pre-construction", "product" and "construction process". The aim of this paper is to compare three different construction solutions for flat roofs, commonly used in Portuguese buildings regarding their economical sustainability. All the solutions have the same functional equivalent, i.e. they are designed to have similar thermal, acoustical and fire protection performance. In order to evaluate the economical sustainability of the different construction solutions, the EcoSust methodology, based on the European standards framework, will be applied. According to this methodology the result of the economic performance is expressed in monetary units and the result of the sustainability performance by an index of economical sustainability (A+, A, B, C, D, E).
