Definir el costo referencial de construcción por metro cuadrado de vivienda unifamiliar sustentable en la ciudad de Cuenca

Abstract

At the global level, the construction industry has a significant impact on the environment by demanding a high consumption of resources and the characteristics of housing on the health and comfort of its habitants. In Ecuador, there is a high percentage of homes with constructive failures, which emphasizes the need to implement sustainable practices in the construction of housing to improve its performance. The study is focused on the analysis of single family dwellings in the city of Cuenca (Ecuador), with the objective of determining the reference costs of construction (per square meter) of the different sustainable levels that could reach the houses with respect to their conventional counterpart. The study is developed in four stages: (1) development of an appropriate methodology to identify costs; (2) Qualitative study on the perception of sustainable housing; (3) Quantitative study of construction costs and the Ecuadorian Value Added (VAE) of housing. It is concluded that sustainable housing presents a cost increase compared to the conventional one of 33.14%, 15.56%, and 4.32% and a VAE reduction of 15.75%, 4.01% and 3.74%, depending on the number of sustainable strategies that are incorporated to the project
