Abstract

This paper starts discussing the relevance of sustainable construction and the role of durability and service life on sustainability. It summarizes the concept of service life planning, as by ISO 15686, and investigates the applicability of this concept to the construction industry of developing countries. Examples and statistical data are given. Conclusions are presented. Durability and service life have very important environmental dimensions. In some languages sustainable construction is translated as durable construction. Durability is much more knowledge-based than resource-based, because it is possible to improve service life without increase environmental loads during production phase. Service life planning implies a use of estimated service life of components as additional design criteria. The concept offers a logical scheme to make rational decisions based on economical (life cycle costs) and environmental (life cycle assessment) aspects. More than 82% of the world population live in so-called developing countries. These countries still need to construct huge amount of houses and infrastructure. In other words, the developing world is still under construction and, potentially, can benefit very much from service life planning tools. However, several constraints like low environmental concern, the self-help construction scheme, higher interest rates and the lack of technical data and experts constitute barriers.
