Sustainable Housing: Location as a Strategic Factor -2014
We carried out a study on social interest housing in two scenarios: horizontal peri-urban and vertical intra-urban. In both cases we considered the same constructed area and an equivalent area of green areas. We proceeded to compare the carbon footprint and life-cycle cost of both types of housing, in both the pre-use stage as well as the usage stage. Significant differences were found between both of them, in their carbon footprint and the costs of their production and use. The study revealed that, taking into account only the pre-use stage, intra-urban housing has a greater cost than the peri-urban, although the carbon footprint is greater in the peri-urban than in the intra-urban. However, considering both stages (pre-use and use), vertical housing has a better performance than horizontal housing: its carbon footprint is smaller and so are the annualized costs paid in that type if housing. The main cause of such results resides in the emissions and costs associated with transportation: those savings in costs from acquiring peri-urban housing are actually transferred by far to the cost of transportation.
