Lessons learned from a study based on the AHP method for the assessment of sustainability in neighborhoods.

The Analytic Hierarchy Process (AHP) is a method that allows complex decisions to be made from impartiality, making it suitable for reaching a consensus among experts seeking to solve a problem. This method has been successfully applied in other investigations, and its use has been extended to several disciplines. This technical paper presents the lessons learned from a study that relied on the AHP method to determine priority aspects for sustainable neighborhoods.

Analysis of the Embodied Energy and CO Emissions of Ready-Mixed Concrete: A Case Study in Cuenca, Ecuador.

Concrete is the most commonly construction material used worldwide. In contrast to other countries, Ecuador lacks studies that determine the environmental impact of the production of construction materials. This research presents a quantification of embodied energy and CO emissions associated with the concrete production, using as a case study a ready-mixed concrete plant in the city of Cuenca, Ecuador.
