The present paper aims to improve the sustainability in the design of construction systems focusing the evaluation of embodied energy and embodied carbon in the beginner step of the life cycle of micro-homes. The micro-homes is usually been an answer to specific needs, like social transformation, economic crisis or strong demand for building. Moreover this micro-home should be also a prototype of the technological innovation and the definition of the building quality (i.e.: prefabrication, study of ergonomics, 3d printing...). Nowadays buildings have to reach two main goals related to sustainability: an environmental sustainability, for a new and major build quality, and an economical sustainability, as a consequence to the social transformation. So the micro-homes are an interesting design theme, and a lot of prototypes of buildings are energy efficient and flexible to several needs of aggregation or of time organization. This paper describes the results of an analysis that compares different construction systems, used to build the same model of micro-home. The values of embodied energy and of embodied carbon of such a case study consent to identify which construction system is the less “energivorous” in the construction phase. In a global sustainability perspective, the reduction of energy consumption must be evaluated and designed considering the whole life cycle of buildings, not just examining the power needed for their management during their use. As a consequence, the computation of the embodied energy and embodied carbon values, even though it has some simplifications, allows a rapid comparison among the different construction systems and stress a debate about the strong and weak points of each one.

Abstract
The present paper aims to improve the sustainability in the design of construction systems focusing the evaluation of embodied energy and embodied carbon in the beginner step of the life cycle of micro-homes. The micro-homes is usually been an answer to specific needs, like social transformation, economic crisis or strong demand for building. Moreover this micro-home should be also a prototype of the technological innovation and the definition of the building quality (i.e.: prefabrication, study of ergonomics, 3d printing...). Nowadays buildings have to reach two main goals related to sustainability: an environmental sustainability, for a new and major build quality, and an economical sustainability, as a consequence to the social transformation. So the micro-homes are an interesting design theme, and a lot of prototypes of buildings are energy efficient and flexible to several needs of aggregation or of time organization. This paper describes the results of an analysis that compares different construction systems, used to build the same model of micro-home. The values of embodied energy and of embodied carbon of such a case study consent to identify which construction system is the less “energivorous” in the construction phase. In a global sustainability perspective, the reduction of energy consumption must be evaluated and designed considering the whole life cycle of buildings, not just examining the power needed for their management during their use. As a consequence, the computation of the embodied energy and embodied carbon values, even though it has some simplifications, allows a rapid comparison among the different construction systems and stress a debate about the strong and weak points of each one.
