HSI Analysis

Evaluation of Housing Sustainability in Mexico

In 2011, a study was carried out under the direction of the Mario Molina Center, with the support of various institutions and the Association for Sustainable Housing and Environment (VESCA), of which Consorcio ARA is a member. The study consisted of an Evaluation of Housing Sustainability in Mexico, the primary result of which was the creation of a Housing Sustainability Index (HSI), as well as the first Lifecycle Analysis of Affordable Entry-Level Housing in Mexico.

Housing Sustainability Index (HSI)

The HSI is an instrument that measures the impact associated with affordable entry-level housing, as well as the urban environment surrounding it. It assigns equal weight to the environmental, economic and social factors involved in housing, seeking out an equilibrium between them. The HSI is composed of 30 indicators, deigned based on a performance scale that establishes a common, long-term metric for reporting housing industry advances in the area of sustainability. It also incorporates 40 regional weighting factors, which set a value scale that determines the weight of the indicators based on the physical, economic and social features of each region.

Lifecycle Analysis of Affordable Entry-Level Housing in Mexico.

This analysis measured and quantified the direct and indirect environmental impact of the construction and use of housing complexes.

In terms of the environment, the results of the Lifecycle Analysis indicate that 17% of the impact of housing and its context occur during the pre-use phase (including extraction, manufacture and transportation of construction materials). The carbon footprint of an Affordable Entry-Level home across its lifecycle was found to be 191, 143, 156, and 156 metric tons of CO2 in the areas of Cancún, Monterrey, Tijuana, and the Mexico City metropolitan area.
