title: Life cycle assessment of two dwellings: one in Spain, a developed country, and one in Colombia, a country under development.
abstract: The main objective of this paper is to study and quantify the differences in energy consumption and environmental impacts of two dwellings during the full building life cycle: one in Spain, a developed country, and one in Colombia, a country under development. In both scenarios, we assessed the construction, use and end-of-life phases. Results show that the use phase in the Pamplona house (Colombia) represents a lower percentage for all impacts in the total than in the Barcelona house (Spain). The findings of this study showed that the difference in consumption in Colombia and Spanish dwellings analysed is not only due to the variation in results for bio-climatic differences but also because of the consumption habits in each country. The importance of consumption habits of citizens and the need to decouple socio-economic development from energy consumption are sought for achieving sustainability from a life cycle perspective. There is a crucial necessity to provide satisfaction to basic needs and comfort requirements of population with reasonable and sustainable energy consumption. Then, the type of standard dwelling varies substantially depending on the geographic location where it is built. Climate, technological, cultural, socio-economical differences clearly define the standard of a building in any context and in any region. However, the function is always the same, to provide protection and housing for its habitants.
