The European construction industry is supposed to consume the 40% of the natural European resources and to
generate the 40% of the European solid waste. Conscious of the great damage being suffered by the environment because
of construction activity, this work tries to provide the building actors with a new tool to improve the current situation. The
tool proposed is a model for the comprehensive evaluation of construction products by determining their environmental
In this research, the environmental level of a construction product has been defined as its quality of accomplishing the
construction requirements needed by causing the minimum ecological impact in its surrounding environment. This
information allows building actors to choose suitable materials for building needs and also for the environment, mainly in
the project stage or on the building site, contributing to improve the relationship between buildings and environment.
For the assessment of the environmental level of construction products, five indicators have been identified regarding their
global environmental impact through the product life cycle: CO2 emissions provoked during their production, volume and
toxicity of waste generated on the building site, durability and recycling capacity after their useful life. Therefore, the less
environmental impact one construction product produces, the higher environmental level performs.
The model has been tested in 30 construction products that include environmental criteria in their description. The results
obtained will be discussed in this article. Furthermore, this model can lay down guidelines for the selection of ecoefficient
construction products and the design of new eco-competitive and eco-committed ones.
